About the project

A modern operating system for risk, compliance, and vendor management in the U.S. mortgage industry is a $12T+ market still relying on fragmented, outdated tools.

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.

You will join a small, senior, high-ownership team:

  • 2 Founders (product, strategy, customer-facing)
  • 1 Founding Engineer (full-stack, infrastructure)

We operate with high trust, clear communication, and full ownership. Everyone on the team directly shapes the product.

tech stack:

  • Frontend: Next.js, React (custom hooks, components), Redux
  • Backend: Express, MongoDB + Mongoose, CRON jobs
  • Infrastructure: Railway, MongoDB Atlas, AWS S3, Sentry
  • Language: JavaScript (migrating to TypeScript in 2026—this is a major priority)
  • Tooling: Slack, Linear, Loom, AI dev tools (Cursor, Roo Code)

If you're thinking "I'd change half of this," good. Tell us why.

must-have experience

  • Strong experience with React and modern frontend development
  • Proven ability to build polished, user-facing interfaces with high attention to detail
  • Experience owning frontend features end-to-end, from idea to production
  • Solid understanding of modern JavaScript (TypeScript experience preferred)
  • Strong grasp of UI/UX principles, component design, and consistency
  • Experience collaborating closely with product and backend teams
  • Comfortable working with evolving requirements and limited specifications

nice to have:

  • Experience with TypeScript (or strong interest in migrating a codebase)
  • Familiarity with AI APIs (OpenAI, Anthropic, etc.) and integration patterns
  • Background in fintech, compliance, or regulated industries
  • Experience with automated testing, QA processes, and error monitoring tools (Sentry, etc.)

responsibilities

  • Build polished, intuitive user interfaces using React and Next.js
  • Own frontend features end-to-end, from concept to release and iteration
  • Translate ambiguous requirements into clear, user-friendly UI solutions
  • Obsess over UI/UX details: spacing, hierarchy, states, edge cases, and consistency
  • Improve and maintain a high-quality component system and frontend architecture
  • Ensure frontend performance, reliability, and graceful error handling
  • Continuously raise the quality bar by refining existing UI and eliminating UX friction
  • Collaborate closely with product and backend to deliver thoughtful, cohesive experiences

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.
