• 7+ years of professional software development experience
• 5+ years of hands-on experience with Node.js and TypeScript
• Solid understanding of backend architecture, distributed systems, and scalable service design
• Experience with front-end technologies (React) sufficient for supporting full-stack delivery
• Strong knowledge of JavaScript/TypeScript runtime patterns and performance considerations
• Experience working with relational databases (PostgreSQL or equivalent)
• Experience with containerized development environments and cloud-native practices

This is not an idea-stage startup.

• Paying customers
• 3,000+ active users

• Proven product-market fit

   

Our goal is to become the default compliance platform for mortgage companies nationwide, with 10,000+ companies using the product daily by the end of 2026.

What You’ll Be Doing

You’ll own features end-to-end from database schema to polished UI. This isn’t a role where you throw code over the wall. You design, build, ship, and maintain.

Immediate priorities (3 — 6 months):

• Build features to reach parity with legacy competitors
• Improve UI/UX across the platform (we’re good, want to be great)
• Develop AI-powered document review/OCR solution to automate compliance tasks

• Triage and resolve production issues surfaced in Sentry

   

Long-term (2+ years):

• Launch Products #3 & #4 to complete the risk and compliance ecosystem
• Help us build the single platform every mortgage bank will rely on—nothing like this exists today

How We Work

Async-first. High-trust. High-agency.

• No daily standups. No micromanagement.
• We review priorities weekly and make sure everyone’s working on the highest-impact task.
• Deadlines and blockers are communicated in Slack. Updates via Loom.
• We value written communication, it forces clarity and works across timezones.
• We’re a curious, opinionated group who debate ideas and seek the best solution, not the loudest voice.
•  

We care deeply about product design and thoughtfulness. The feedback we hear most on demos is: “Wow, it looks so great and feels so intuitive.” We’re proud of that but we know we can do even better.
