Job summary

Revin in New York City is seeking a Software Engineer to build the production systems behind our AI agents—the components that handle SMS, voice, and email conversations for multi-million-dollar home-service operators.

You will work across a Python/FastAPI backend, a Next.js/TypeScript dashboard, and LangGraph workflows, shipping in production with product, design, and senior engineers. 2–4 years of startup-scale full-stack experience is preferred.

Qualifications

• 2–4 years of full-stack experience shipping production software at a startup, high-velocity SaaS, or AI-driven company.
• Eager to work with LLMs in production — you've built with LLM-powered features and want to go deeper, even if you haven't owned them at scale yet.
• Working proficiency in Python (FastAPI) and TypeScript (Next.js, React Query).
• Comfortable working in production systems, and eager to learn multi-tenant patterns — RLS, account-scoped queries, JWT-based access.
• Experience debugging APIs and tracing issues across services and data pipelines.
• A continuous learner comfortable operating in ambiguity. You ship, learn, and adapt.
• Customer-obsessed — you want to be close to the people using what you build.

Responsibilities

• Build and evolve LangGraph workflows that handle SMS and voice conversations for enterprise operators
• Ship features end-to-end across a Python/FastAPI backend and a Next.js/TypeScript dashboard
• Work in a multi-tenant Supabase/Postgres environment where every query is account-scoped (RLS, JWT-based access)
• Help build the eval frameworks that catch agent regressions before they reach customers — we treat eval quality as a first-class engineering discipline
• Integrate with messy real-world CRMs (Salesforce, ServiceTitan, LeadPerfection, AccuLynx) where the data is never clean
• Partner with the voice team on real-time agent behavior (LiveKit + OpenAI Realtime)
• Help optimize the omnichannel experience across SMS, voice, and email
