Senior Software Engineer

• At Revin, we're bringing AI to the built world. Millions of operators across
• home services, construction, and remodeling have been overlooked by the last
• wave of technology. We're building the system of intelligence that lets them
• automate and scale revenue.
• Today, over $2.3B in revenue runs on Revin, making us the #1 AI partner for
• enterprise operators in this market. Our customers include Sears Home Services
• ($800M), Astara Capital ($700M), Del Air ($150M), Long Home Remodeling
• ($150M), ImproveIt Remodeling ($100M), Sage Home ($80M), and more.
• We've raised $10M from Stellation Capital, 1Sharpe, Gokul Rajaram, Russ
• Heddleston, Michael Werner, Tandem, Max Branzburg, and Marc Bhargava.

About the Role

• We're hiring an Senior Software Engineer to build the production systems behind our
• AI agents — the agents that handle SMS, voice, and email conversations on
• behalf of $100M+ home-services operators. When our agent makes a mistake —
• books outside hours, dispatches to the wrong zip code, promises a service the
• business doesn't offer — it costs our customers real money. Your job is to
• build the systems that prevent that.
• This is a high-ownership role. You'll work end-to-end across a Python/FastAPI
• backend, a Next.js/TypeScript dashboard, and the LangGraph workflows that
• drive agent behavior. You'll partner directly with product, design, and
• leadership, ship in production, and influence the direction of the platform.

What You Will Do

• 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)

• 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)

• Optimize the omnichannel experience across SMS, voice, and email

Who You Are

• 4–8 years of full-stack experience shipping production software at a

startup, high-velocity SaaS, or AI-driven company

• Production LLM experience — you've shipped LLM-powered features that real

customers depend on, not just prototypes or internal tools

• Fluent in Python (FastAPI) and TypeScript (Next.js, React Query)
• Comfortable working in multi-tenant production systems — RLS, account-scoped

queries, JWT-based access

• Experience debugging APIs, tracing distributed issues, and working with

event-driven systems and unstructured 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

Bonus

• LangGraph, LangChain, or other agent frameworks in production
• Real-time voice/audio work (LiveKit, Daily.co http://Daily.co, Twilio Voice)
• Observability tooling for LLM systems (Langfuse, LangSmith, Helicone)

Don't Apply If

• You wait for instructions instead of taking initiative
• You want a predictable, low-ownership role. We move fast, ship in

• production, and own outcomes end-to-end. If you're optimizing for
• predictability, this won't be a fit.

• You're not excited about applying AI to the built world. There's no playbook

here. If you want a well-trodden path, this isn't the role.
