• Remote Job*

Client builds loan application software for the US mortgage industry. Client is based in Miami, with a team of five spread across the US West Coast, Brazil, South Africa and Spain. The hard integrations are happening now. They are working through certifications with mortgage agencies and integrations with government data sources, some well along and some just starting.

The role

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: they look at the forms, the documents and the borrower flow, then design endpoints that fit them. You should be able to reason about how a decision in your area ripples through the rest of the system: the frontend, the integrations, compliance, and the people who maintain it after you.

What you''ll do

• 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, the format we submit to Freddie Mac and Fannie Mae.
• 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. That includes the certification work each one requires.
• 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.
