Y Combinator Full Stack Software Engineer
Summary
Build and ship end-to-end features for an AI-native platform that lets companies securely deploy agents; work closely with users and own production systems.
About Us
Gumloop is the piece of AI infrastructure companies roll out to let everyone build agents securely. Let people who understand the problem build and share agents, manage their access to data, choose your AI models and host it all in your own cloud.
We're a very small team building as fast as humanly possible. Gusto, Ramp, Shopify, Samsara, Instacart, and Opendoor are running agents on Gumloop across their company. We've raised over $70M from Benchmark, First Round Capital, Y Combinator, Nexus Ventures to scale operations and are looking for people who care as much as we do to join the team.
Role Overview
We're looking for an experienced Full Stack Engineer to ship product at the highest level. You'll own features end-to-end — design, build, test, deploy, and operate them in production. This is a role for engineers who want close proximity to users, fast feedback loops, and the opportunity to directly shape the trajectory of an AI-native platform.
What You'll Do
Ship end-to-end features — design, code, test, deploy, and own them in production
Work directly with users to turn feedback into improvements within hours, not days
Build and operate frontend and backend systems that stay fast and reliable as traffic grows
Review PRs, share context, and mentor junior engineers to raise the bar across the team
What You Bring
2–5 years of professional experience building products as a full stack developer
Relentlessly resourceful — you've built real-world applications with a high bar for quality
If you've personally built something people use, years of experience is basically irrelevant
Comfort working in a small team where ownership and speed are the norm
Bonus
Prior experience as a founder or founding engineer
Strong sense of product taste
Experience building LLM-powered products
Proficiency in Python, TypeScript, React, TailwindCSS, Redux
