Job Description

This is a remote position.

Fountain Forward is hiring a Senior Full-Stack Developer to lead the design, build, and launch of our client portal while mentoring and managing a team of four junior developers. This role is hands-on: you will ship code, own architecture decisions, and raise the technical bar of the team.

Responsibilities

• Own the end-to-end technical delivery of the Fountain Forward client portal, from architecture to production.
• Lead, mentor, and manage a team of 4 junior developers through code reviews, pairing, and technical planning.
• Design scalable backend services in Python (FastAPI) and a performant Next.js (TypeScript) frontend.
• Architect data flows across Supabase (Postgres), Redis, and BigQuery, ensuring reliability and cost efficiency.
• Set engineering standards: testing, CI/CD, code quality, observability, and security best practices.
• Collaborate with product, data, and leadership to translate business goals into technical roadmaps.

Requirements

Required Experience

• 5+ years building production web applications, with at least 2 years in a senior or lead role.
• Strong proficiency in Next.js and TypeScript, including App Router, server components, and modern React patterns.
• Solid backend experience with Python and FastAPI, including async programming and REST/RPC API design.
• Hands-on experience with Postgres (Supabase a plus), Redis for caching and queuing, and BigQuery for analytics workloads.
• Familiarity with optimization and RPC frameworks (e.g., gRPC, tRPC, Protocol Buffers, or equivalents).
• Proven track record of mentoring junior engineers and leading small teams.
• Comfort with cloud infrastructure, CI/CD pipelines, and production monitoring.

Nice to Have

• Experience with data-heavy or analytics-facing client portals.
• Background in performance optimization at scale (query tuning, caching strategies, frontend performance).
• Exposure to event-driven architectures and background job processing.
• Previous experience in an agency, consultancy, or fast-moving product environment.
