[Hiring] Senior Full-Stack Engineer @Stefanini Group

Role Description

Stefanini is looking for a Senior Full-Stack Engineer in Remote - USA. This is a senior, backend-leaning full-stack role. Most of your time goes into Python services, our GraphQL API, and AWS infrastructure. You'll also work in our React/TypeScript frontend. We want someone who shapes the API around what the product actually captures.

• Design and own the GraphQL schema and the Python services behind it, shaped around the data and flows the frontend captures.
• Own the mapping between our data model and the loan application (URLA / Form 1003) as MISMO XML.
• Build and harden the OCR pipelines that turn borrower documents into structured, verifiable data.
• Own third-party integrations end to end, including Freddie Mac, Fannie Mae, data and verification providers, and the upcoming IRS integration.
• Ship frontend features in React/TypeScript when that's the fastest path, and work with design on the upcoming redesign.
• Break work into pieces you can estimate, commit to dates, and raise slippage early instead of at the deadline.
• Take on product, QA, infrastructure or vendor work when the stage calls for it, and keep the thread when you switch.
• Give and ask for direct feedback, in code review, in design discussions and about how the team works.

Qualifications

• Senior-level engineering experience (typically 5+ years), with systems you designed and own running in production.
• Strong Python backend skills and production experience designing GraphQL APIs.
• Hands-on AWS experience: you've deployed, operated and debugged what you built.
• Experience mapping application data to and from large, strict XML schemas.
• Working fluency in React and TypeScript, enough to build features and to judge how an API decision lands in the UI.
• Hands-on experience using agentic AI tools (such as Claude Code, Cursor or Copilot) for coding, testing and documentation.
• Startup experience on a small team, where scope was ambiguous and you owned outcomes, not just tickets.
• Experience in fintech or another regulated domain, such as handling PII, keeping audit trails, or building to external compliance requirements.
• A track record of estimating work and delivering on it, with examples of what you did when an estimate slipped.
• Comfort giving and receiving direct feedback, and clear written communication across time zones.

Requirements

• Hands-on work with the URLA (Form 1003) and MISMO 3.4 / ULAD, including GSE submissions.
• Other mortgage industry experience, such as loan origination systems or GSE integrations (Freddie Mac LPA, Fannie Mae DU).
• OCR or document-processing pipelines in production.
• Integrations with government data sources, including the IRS.
• Experience going through a vendor certification or partner approval process.

How we work

• Feedback goes both ways. We say it directly and early, and we expect the same from you.
• Estimates are commitments. We expect them to change sometimes, and when they do, we say so as soon as we know.
• Everyone wears several hats. At five people, you'll move between engineering, product, QA, and ops.
• We decide with the whole system in view. A good backend change considers the frontend, the integrations, and the compliance trail.
