About Revin

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

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, 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.
