About the RoleA seed-stage construction lending fintech is looking for a
Full-Stack Engineer with
6+ years of experience to join a small, high-velocity remote team. You'll work across the entire stack - from database schema design and API development to React front-end UI - extending and improving a mature, mission-critical Rails monolith that powers construction lending workflows. This is a hands-on, high-ownership role for a pragmatic engineer who thrives in ambiguity and is genuinely curious about domains outside their own expertise.
Experience in construction, fintech, proptech, or any domain requiring deep business understanding is a strong plus.
Visa sponsorship is not available; candidates must have U.S. work authorization.
What You'll Do- Collaboratively define, scope, and architect new platform capabilities on top of a 6-year-old Rails monolith serving mission-critical construction lending workflows
- Take ownership of extending and improving legacy systems - adding payments, integrations, and new features in a seamless, secure, and scalable way
- Write and optimize SQL, design schema migrations, and ensure API payloads are efficient and well-structured
- Develop and maintain web (React, Hotwire, TypeScript, Tailwind) and mobile-facing (React Native) features, ensuring platform alignment
- Manage background processing and job queuing (Sidekiq) to ensure system reliability without over-reliance on expensive vendor solutions
- Identify where legacy implementations need improvement and propose practical migration paths balancing engineering quality with business constraints
- Help establish engineering culture, conventions, and development practices as the team scales
- Serve as a technical leader and mentor others on the team
- Manage the end-to-end software delivery lifecycle, including testing, release management, and monitoring
- Communicate proactively in a fully remote, async-friendly environment - articulate your thinking, ask the right questions, and collaborate through conversation
What We're Looking ForRequired (dealbreakers):- 6+ years of full-stack software development experience in production environments
- Strong proficiency with Ruby on Rails, including extending and maintaining mature monoliths and legacy systems
- Experience shipping and maintaining production applications used by real customers

Also required:- Proficiency with React, TypeScript, Tailwind, and Hotwire
- Experience with mobile frontend development using React Native
- Strong SQL and PostgreSQL experience, including schema design and migrations
- Experience with background processing and job queues (Sidekiq)
- Hands-on experience with payments integrations and related API design, ideally within fintech, proptech, or construction lending
- Ability to architect platform capabilities, scope features, and make sound design decisions for scalable systems
- Comfort working cross-functionally and communicating problems and solutions clearly
- Strong problem-solving skills in ambiguous, fast-moving environments
