About Revin

At Revin, our mission is to bring super intelligence to the built world. Millions of operators across Home Services, Construction, and Remodeling have been overlooked by the last wave of technology. We believe AI is the most transformational platform change in history, but the hard work lies in thoughtful, context-aware applications of this technology to the real world.

Revin provides operators with an end-to-end system of intelligence to automate and scale revenue. Our modular suite of products includes Scheduling, Appointment Management, Membership Management, Inside Sales, Revenue Capture, Marketing, and Funnel Optimization.

Today, over $2.3B in revenue runs on Revin, making us the number one AI partner for enterprise operators. 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 have raised $10M from top investors including Stellation Capital, 1Sharpe, Gokul Rajaram, Russ Heddleston, Michael Werner, Tandem, Max Branzburg, and Marc Bhargava.

About the Role

We’re hiring a Fullstack Engineer to build the systems that turn AI into reliable, real-world products used by operators running $100M+ businesses. This is a high-ownership, high-impact role for engineers who want to work on applied AI in the real world where reliability, performance, and user experience matter. You should be comfortable owning problems end-to-end — from backend systems to frontend UX — and shipping quickly in production.

You will work across the stack, from agent logic and data pipelines to customer-facing tooling and omni-channel delivery. You’ll work with messy, real-world data and systems — not clean datasets or controlled environments. You will partner closely with product, design, and leadership to ship fast, iterate in production, and directly influence the direction of the platform.

What You Will Do

Build and scale production AI systems, including agent orchestration, data pipelines, and customer-facing applications
Design systems to handle unstructured data and event-driven workflows
Improve conversation quality and internal agent tooling used by onboarding and customer success teams
Optimize the omni-channel experience across SMS, email, and voice
Contribute to evaluation frameworks for AI agents to improve accuracy and reduce errors
Work closely with product and design to ship quickly, test in production, and iterate based on real customer feedback

Who You Are

An engineer with 3–8 years of fullstack experience shipping products at a startup, high-velocity, or AI-driven company
Someone with top-tier education in a highly selective and academically rigorous environment and/or experience at top-performing SaaS or AI companies. Advanced degrees are a plus
A customer-obsessed go-getter who wants to be in the field, getting as close to the product as possible
An ambitious builder who wants to build a generational product
A continuous learner comfortable operating in ambiguity. You ship, learn, adapt, and are constantly looking for new information
Fluent in Python, React, and TypeScript, comfortable working with REST APIs and cloud-based architectures, and able to move up the stack when needed
Comfortable testing and debugging APIs, tracing issues, and working with event-driven systems and unstructured data pipelines
Bonus if you have built or deployed LLM frameworks, language models, or AI agents in production environments

Don’t Work Here If

You wait for instructions instead of taking initiative
You want a safe, predictable 9-5. Expect 50+ hour work weeks. We are looking for fanatics who do not turn off. We are constantly chasing excellence, if that is not your goal, please do not apply
You are not excited about being part of a team applying AI into the built world. There will be no playbook, if you want a well-trodden path, this is not the role for you
