Role Overview: We're looking for a Full-Stack Developer to build and own features end-to-end on an AI-powered Customer Success platform. You'll work across the stack — Next.js or React on the frontend and Python / FastAPI with PostgreSQL and Redis on the backend — and help ship LLM-driven features like sentiment analysis, meeting summaries, and automated insights. This is a hands-on role for someone with 3–5 years of experience who's comfortable moving between UI, APIs, and data. Key Responsibilities: Frontend • Build responsive, polished interfaces using Next.js or React — dashboards, charts/KPIs, tables, and workflow views. • Collaborate with designers to implement UI accurately; handle loading, error, and empty states cleanly. Backend & APIs • Develop RESTful services using Python and FastAPI in a microservices architecture. • Design clean API contracts that your own frontend consumes. Database & Performance • Design and maintain PostgreSQL schemas (Supabase); write and optimize SQL, add indexes, pagination, and Redis caching to keep endpoints fast. AI / LLM Integration • Integrate LLM APIs (OpenRouter / OpenAI / Anthropic) for summaries, sentiment, and content generation; help refine prompts and structure model outputs. Quality & Collaboration • Write clean, well-documented, testable code; debug across the stack. • Handle authentication/authorization (JWT + RBAC). • Participate actively in team meetings, code reviews, and planning. Required Skills/Experience: • Bachelor's in Computer Science, IT, or related field. • 3–5 years of full-stack development experience. • Frontend: strong experience with Next.js or React. • Backend: solid Python with a web framework — FastAPI preferred (Flask/Django acceptable). • Strong SQL / PostgreSQL: schema design, query optimization, indexing. • Solid REST API design and integration experience. • Familiarity with Git. Nice to have • Experience integrating LLM / AI APIs and prompt engineering. • TypeScript, Supabase, Redis, async Python. • Microservices, Docker, CI/CD, data visualization/charting libraries. What makes you stand out • You've shipped features end-to-end (DB → API → UI) and care about both clean code and good UX.
