Senior Full Stack Engineer (ruby on rails)
Senior Full-Stack Engineer (Rails Monolith + React)
Location: Remote (U.S.)
About Our Client
Our client builds software that powers mission-critical construction lending workflows. The platform is mature, used by real customers, and sits at the intersection of complex operational processes, payments, approvals, and data accuracy. This team values pragmatic builders who can ship, iterate, and improve legacy systems without breaking what already works.
The Role
Our client is hiring a Senior Full-Stack Engineer who has shipped and maintained production applications, someone comfortable moving across database design, API development, backend architecture, and front-end product work.
Youâll help define and build new platform capabilities on top of a 6-year-old Rails monolith, improving and extending it with modern patterns while balancing speed, quality, and business constraints.
What Youâll Do
⢠Collaboratively define, scope, and architect new platform capabilities on top of a mature Rails monolith
⢠Extend and improve legacy systemsâadding payments, integrations, and new features in a way thatâs seamless, secure, and scalable
⢠Work directly with databases: write/optimize SQL, design schema migrations, and ensure API payloads are efficient and well-structured
⢠Build and maintain web features using React, Hotwire, TypeScript, Tailwind (and potentially mobile-facing work in React Native)
⢠Manage background processing and system reliability using Sidekiqâtaking a pragmatic approach to infrastructure without overbuying vendor tooling
⢠Identify fragile legacy implementations and propose practical migration paths that balance engineering quality with business reality
⢠Help establish engineering culture, conventions, and development practices as the team scales
⢠Communicate proactively in a fully remote, high-velocity environmentâthinking out loud, asking the right questions, and collaborating through conversation
What Our Client Is Looking For
Required
⢠6+ years of professional full-stack engineering experience (exceptional 4â5 years considered)
⢠Strong Ruby on Rails experience, including working inside a mature monolith
⢠Comfortable working across backend + frontend, with strong product instincts
⢠Solid database fundamentals: schema design, migrations, query optimization, and API efficiency
⢠Experience building reliable systems: background jobs, queues, retries, and failure handling (Sidekiq or similar)
⢠Clear communicator who thrives in ambiguity and can reason out loud
Bonus Points
⢠Experience in construction, fintech, proptech, or any domain requiring deep business learning to build the right product
⢠Experience with React Native or mobile-adjacent product surfaces
⢠Experience integrating payments and third-party systems in production
Why This Role
⢠High-ownership work on a platform that mattersâreal customers, real workflows, real outcomes
⢠Meaningful engineering challenges: improving a mature codebase, scaling reliability, and modernizing without ârewrite theaterâ
⢠Strong influence on architecture, standards, and how the team builds as it grows
⢠Remote culture that rewards proactive communication and practical execution
