Senior/Staff Software Engineer Remote (US) United States Full-time Remote (US/Canada must work U.S. hours)

Mortgage lending still runs on 20-year-old software and it costs over $11000 in human effort to originate a single loan. Youd be building the AI-native systems that make that cost disappear.

What youd actually work on

• Architect build and ship multi-step AI agents that customers use to digitize mortgage ops workflows saving them millions per year in manual processing.
• Integrate with third-party lending APIs to generate documents and disclosures produce automated underwriting results and catch fraud before it hits a human reviewer.
• Design and launch the next generation of job-processing infrastructure on AWS focused on observability and reliability at scale.
• Work directly in a codebase handling loan data with thousands of fields per record so schema decisions have real downstream consequences.
• Ship to production in week one. No multi-month onboarding runway youre expected to contribute fast.
• Mentor engineers earlier in their career on both technical depth and judgment calls.
• Own features end to end from design through deployment for enterprise mortgage lender customers.

Where it gets technically interesting

• Nearly the entire codebase is TypeScript in a single monorepo with types generated directly from Postgres and GraphQL schemas so a database change surfaces as a compile error in React components.
• 100% of infrastructure has been managed in Terraform since day one with automated per-PR staging environments so nothing gets deployed by hand.
• Youre wrangling non-deterministic LLMs into systems that have to be reliable for a regulated high-stakes financial process not just a chatbot.
• AWS backend runs on ECS RDS ElastiCache Kafka and ElasticSearch with real throughput demands as loan volume scales.
• The platform stores and displays highly sensitive personal and financial data so security isnt an afterthought its baked into every schema and endpoint decision.
• A comprehensive testing library mocks production-like data for end-to-end integration and performance tests which is what lets the team ship fast without breaking uptime.

What were looking for

• 7 to 25 years of full-stack engineering experience with at least 5 years operating at a Senior level.
• Strong demonstrable TypeScript depth ideally with recent complex systems youve built hands-on and can talk through in detail.
• Production experience with React Node/Express (in Docker) GraphQL/Apollo and PostgreSQL.
• Experience scaling high-throughput distributed systems in the cloud with AWS and infrastructure-as-code (Terraform or CloudFormation).
• A background at a high-growth tech company where software was the actual product (VC-backed startup or FAANG) not a traditional industry running internal tools.
• 2 years of tenure and real progression within the companies on your resume.
• A sharp eye for security risk given the sensitivity of the data involved.
• Nice to have: fintech background familiarity with AI product development cycles (evals experiment design dataset curation) an SRE mindset and an active GitHub or side projects.
