Hummingbird is a remote-first, fully distributed team united by the shared mission of helping fight financial crime. Since our launch in 2017, we’ve helped major financial institutions and tech-savvy trailblazers alike (e.g. Stripe, Affirm, Evolve Bank etc.) orchestrate their compliance programs through our thoughtfully designed, intuitive SaaS product. We believe finding and stopping financial crime is a problem rooted in code, language and design, so we built the product that the heroes doing this work deserve.

We are customer-obsessed, and we love building and shipping great products. We set a high bar, challenge our assumptions, seek diverse opinions, and support each other to do our best work.

We do our best to write inclusive, descriptive and accurate job descriptions, but we’re not always perfect. If you’re interested in the role, we’d love to hear from you even if you don’t feel like you meet everything we’re looking for.

Data Engineering builds and maintains the reliable foundation that makes trusted data possible, enabling teams across Splice to work from a governed, consistent source of truth. We are accountable for the warehouse and pipeline foundation; ingestion, transformations, and the standards and quality guardrails that keep data consistent, timely, and usable. This is a mid-level, high-ownership role: engineers here carry features from technical design through delivery, monitoring, and documentation, and participate in our on-call rotation.

The work requires hands-on data engineering experience. Our stack; BigQuery, SQLMesh, Python, Dagster- is distinct from Splice’s web engineering stack, and effective contribution requires domain expertise in data pipeline systems, not general software engineering background.

TEAM INFORMATION:

You’ll be joining Splice’s Data Engineering team, a small, embedded platform team responsible for the pipelines, transformations, and warehouse infrastructure the rest of the company depends on. Our systems support finance-critical processes (contributor payouts, GAAP revenue reporting), product analytics, and data reliability for customer-facing features like recommendations. We operate with a shared on-call rotation and a strong bias toward observable, well-documented, durable systems.

WHAT YOU’LL DO:

Pipeline Development & Transformation

• Build and maintain data models in SQLMesh, including incremental strategies, testing, and documentation
• Continuously improve and evolve our orchestration and transformation infrastructure as the platform scales
• Modernize legacy pipeline jobs in Python and SQLMesh, reducing technical debt over time

• Participate in on-call rotation; triage and resolve incidents including ETL failures, data unavailability, and core metric breakage
• Build introspectable software: define alert thresholds, emit metrics and logs, produce dashboards, and establish closed-loop escalation paths
• Improve observability across the platform so failures are caught early and resolved quickly

Finance & Revenue Pipelines

• Extend and maintain pipelines powering creator payouts and GAAP-compliant revenue reporting across Splice’s product lines
• Build pipeline support for new revenue streams as Splice launches them

Platform Quality & Optimization

• Improve query performance and reduce compute costs in BigQuery
• Contribute to ingestion platform work and product analytics infrastructure
• Uphold our definition of done: validation complete, documentation updated, monitoring in place before closing a ticket

JOB REQUIREMENTS:

• 3+ years of hands-on data engineering experience in a production environment
• Proficiency in SQL — window functions, CTEs, query optimization, execution plan analysis
• Proficiency in Python for pipeline logic, data transformation, and testing (maintainable code, not just scripts)
• Experience with a modern transformation framework — SQLMesh, dbt, or equivalent — including incremental models, testing, and documentation
• Production experience with a cloud data warehouse (we use BigQuery); understands partitioning, clustering, and cost management
• Experience with at least one workflow orchestrator (Dagster, Airflow, Prefect, or equivalent)
• Demonstrated ability to build observable, reliable data systems — alerting, dashboards, and data quality checks
• Comfortable owning small-to-medium features from technical design through delivery with limited guidance

SPLICE BENEFITS:

• Compensation & Equity: Competitive pay with annual reviews and equity opportunities.
• Time Off: Unlimited PTO to recharge and thrive.
• Health & Wellness: Comprehensive medical, dental, and vision coverage for you and your dependents.
• Retirement Savings: 401(k) plan with immediate vesting and company match.
• Parental Support: 12 weeks of fully paid parental leave for non-birthing parents, and 18-20 weeks for birthing parents.
• Flexible Work Options: Work remotely or connect at our office hubs and creative spaces worldwide.
• Professional Growth: Annual learning budget, leadership programs, and team ambassador opportunities.
• Community & Connection: Inclusive events, team meet-ups, and vibrant Employee Resource Groups.

The national pay range for this role is $94,952 - $118,690. Individual compensation will be commensurate with the candidate’s experience.

Splice embraces a culture of remote work. You’ll see your colleagues showing up from across the US and the UK. In order to keep us working well as a team, we have regular communication, including Town Halls, departmental all-hands and get-togethers.

When you join Splice, you join a network of colleagues, peers, and collaborators. Are you ready?

JOB TITLE: Data Engineer II LOCATION: REMOTE- US

THE ROLE:

We’re looking for a Data Engineer II to join Splice’s Data Engineering team and help scale the platform that powers creator payouts, revenue reporting, and product analytics across Splice’s product lines.

Data Engineering builds and maintains the reliable foundation that makes trusted data possible, enabling teams across Splice to work from a governed, consistent source of truth. We are accountable for the warehouse and pipeline foundation; ingestion, transformations, and the standards and quality guardrails that keep data consistent, timely, and usable. This is a mid-level, high-ownership role: engineers here carry features from technical design through delivery, monitoring, and documentation, and participate in our on-call rotation.

The work requires hands-on data engineering experience. Our stack; BigQuery, SQLMesh, Python, Dagster- is distinct from Splice’s web engineering stack, and effective contribution requires domain expertise in data pipeline systems, not general software engineering background.

TEAM INFORMATION:

You’ll be joining Splice’s Data Engineering team, a small, embedded platform team responsible for the pipelines, transformations, and warehouse infrastructure the rest of the company depends on. Our systems support finance-critical processes (contributor payouts, GAAP revenue reporting), product analytics, and data reliability for customer-facing features like recommendations. We operate with a shared on-call rotation and a strong bias toward observable, well-documented, durable systems.

WHAT YOU’LL DO:

Pipeline Development & Transformation

• Build and maintain data models in SQLMesh, including incremental strategies, testing, and documentation
• Continuously improve and evolve our orchestration and transformation infrastructure as the platform scales
• Modernize legacy pipeline jobs in Python and SQLMesh, reducing technical debt over time

Reliability & Observability

• Participate in on-call rotation; triage and resolve incidents including ETL failures, data unavailability, and core metric breakage
• Build introspectable software: define alert thresholds, emit metrics and logs, produce dashboards, and establish closed-loop escalation paths
• Improve observability across the platform so failures are caught early and resolved quickly

Finance & Revenue Pipelines

• Extend and maintain pipelines powering creator payouts and GAAP-compliant revenue reporting across Splice’s product lines
• Build pipeline support for new revenue streams as Splice launches them

Platform Quality & Optimization

• Improve query performance and reduce compute costs in BigQuery
• Contribute to ingestion platform work and product analytics infrastructure
• Uphold our definition of done: validation complete, documentation updated, monitoring in place before closing a ticket

JOB REQUIREMENTS:

• 3+ years of hands-on data engineering experience in a production environment
• Proficiency in SQL — window functions, CTEs, query optimization, execution plan analysis
• Proficiency in Python for pipeline logic, data transformation, and testing (maintainable code, not just scripts)
• Experience with a modern transformation framework — SQLMesh, dbt, or equivalent — including incremental models, testing, and documentation
• Production experience with a cloud data warehouse (we use BigQuery); understands partitioning, clustering, and cost management
• Experience with at least one workflow orchestrator (Dagster, Airflow, Prefect, or equivalent)
• Demonstrated ability to build observable, reliable data systems — alerting, dashboards, and data quality checks
• Comfortable owning small-to-medium features from technical design through delivery with limited guidance

SPLICE BENEFITS:

• Compensation & Equity: Competitive pay with annual reviews and equity opportunities.
• Time Off: Unlimited PTO to recharge and thrive.
• Health & Wellness: Comprehensive medical, dental, and vision coverage for you and your dependents.
• Retirement Savings: 401(k) plan with immediate vesting and company match.
• Parental Support: 12 weeks of fully paid parental leave for non-birthing parents, and 18-20 weeks for birthing parents.
• Flexible Work Options: Work remotely or connect at our office hubs and creative spaces worldwide.
• Professional Growth: Annual learning budget, leadership programs, and team ambassador opportunities.
• Community & Connection: Inclusive events, team meet-ups, and vibrant Employee Resource Groups.

The national pay range for this role is $94,952 - $118,690. Individual compensation will be commensurate with the candidate’s experience.

Splice is an Equal Opportunity Employer Splice provides equal employment opportunities to all employees and applicants for employment and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state or local laws.

We’ve trained over 40,000 students from 1,000+ universities, and our partners include Amazon, Google, and other leading technology companies. We’ve spent nearly a decade training the next generation of technical talent, and we just launched a $150M initiative with Anthropic, building one of the most ambitious AI workforce programs in the world.

We’re now expanding into new markets and scaling our team so we can move at the speed AI is transforming the workforce. People joining CodePath now will have the opportunity to help architect the next frontier of our work.

We believe technical skill is the fastest way to turn raw talent into real opportunity. We train the engineers the AI era runs on, building toward millions of learners, hundreds of millions in revenue, and billions in economic impact. If you want to own something and be part of a 0-to-1 journey at an organization moving at the speed of AI, this is the place to build it.

About the Role

Location: Remote, United States, Europe, Canada or LATAM

Role-Type: Full-Time

Reports To: VP of Engineering

Compensation: $170,000 to $190,000 per year for US based applicants. Adjusted contingent on location for applicants based in Canada, LATAM, and Europe.

CodePath’s educational programs run on our sophisticated learning platform, a set of Ruby-based applications with functionality spanning admissions, course delivery, grading, career coaching, and reporting.

We’re looking for a Staff Software Engineer who can lead at multiple levels at once: the architecture, the product direction, the team’s capacity, and the longer arc of where we’re going. You’ll move fluidly across the full technical stack, from infrastructure decisions to greenfield product work.

This is a high-ownership role. You’ll work directly with stakeholders to understand what students and staff actually need, participate in deciding what gets built, and then lead the execution. You won’t be handed a ticket queue. You’ll shape the work.

The ideal candidate for this role is a web engineer inspired by potential projects like these:

• Building brand-new functionality in Rails and beyond to create sophisticated and powerful new tools for our users and extend our reach to new kinds of learners we’ve never been able to serve before

• Reimagining core platform components as we migrate them from Sinatra to Rails

• Integrating AI/ML technology into our platform to support mastery-driven, adaptive learning

• Scaling a system that has helped tens of thousands of students to help hundreds of thousands more

Key Activities

• Architect and build web applications across Ruby on Rails, Sinatra/Padrino, and Django that directly support our mission

• Make consequential technical decisions on infrastructure, data modeling, API design, and emerging technologies with full ownership of the tradeoffs

• Set the code quality bar through reviews, architectural guidance, and constructive feedback

• Write automated tests that reflect real edge cases, not just coverage targets

• Identify performance bottlenecks and systemic issues before they become outages

• Mentor other engineers and raise the technical ceiling of the team

Qualifications

• 10+ years of software engineering experience, including at least 5 years with Ruby on Rails

• Familiarity with Claude Code or similar development tools and related best practices

• A systems-thinking orientation: you consider scalability, maintainability, and failure modes before writing a line of code

• Strong PostgreSQL and database design skills, including experience with complex queries, indexing strategies, and schema evolution

• Reasonable working familiarity with the full web stack, from infrastructure to CSS

• Demonstrated ability to lead technical decisions in a small, autonomous team environment

• Strong written and verbal communication. You can explain a technical tradeoff to a non-engineer without losing what actually matters

• Passion for education and desire to make a positive impact

Nice to haves

• Familiarity with higher education or edtech

• Direct experience working with LLMs and generative AI in production

• Familiarity with Docker, Ansible, and/or Terraform

• Experience deploying on GCP

Full-Time Employee Benefits:

This is a 100% remote position! CodePath prioritizes employee well-being with a competitive benefits package to support your health, financial security, and work-life balance.

• Health & Wellness: Medical, dental, and vision insurance (90% employer-covered for employees and dependents), employer-funded healthcare reimbursement, FSAs, and Employee Assistance Program

• Financial Security: 401(k), employer-paid life & disability insurance, and identity theft protection

• Work-Life Balance: Generous PTO, paid holidays, 10 weeks of fully paid parental leave, and an annual year-end company closure (Dec 24 – Jan 2)

• Professional Growth: $1,000 annual professional development stipend and home office setup support

• ​​Student Loan Forgiveness: CodePath is a qualifying employer for Public Service Loan Forgiveness (PSLF), helping employees manage student loan debt

• Additional Perks: Pet wellness plans, legal services, home/auto insurance discounts, and exclusive marketplace savings
