Interfere empowers engineers, product managers and designers with real-time understanding of previously unseen bugs and issues. Backed by Y Combinator.
About the role
You'll own the intelligence layer that makes Interfere work. The product is only as good as the systems that decide what's broken, what caused it, and what to do about it — and those systems live inside the agents, evals, and inference pipelines you'll build. You'll work where research meets production, shipping things that run at scale against real codebases and runtime data. Concretely, this looks like building:
What they're looking for
- You've shipped ML or LLM-powered systems into production, where real users depend on the output, not just a notebook or a demo
- You move between research and engineering comfortably, and you pick up unfamiliar tech fast. You can go from a new framework or technique on Monday, to a working prototype by Friday, to an eval that tells you whether it's actually better the following week
- You can own something 0→1, beginning to end. You can take an ambiguous AI problem, define the next useful step, and ship without waiting for a fully specified plan
- You treat evals as a first-class engineering problem. When the system is making decisions for users, intuition isn't a substitute for measurement
- Experience with agent architectures, tool use, multi-step reasoning, or autonomous workflows in production
More about this role
Interfere turns a product's invisible failures into shared problems the whole team can see and fix. Every app has places where users get confused, blocked, or forced to abandon a flow, but most of those moments never make it into a support ticket. We detect those failures in real-time and provide every person responsible for the fix with the context they need. When Interfere flags a broken checkout flow, the PM uses our data to prioritize the issue, the designer sees where the experience broke down, and the engineer pulls the trace underneath. We're building the operating system for product quality, so teams can move from scattered symptoms to a shared understanding of what's actually going wrong. We're a seven-person team in New York, with $5.1M raised from Y Combinator, Vercel Ventures, Hummingbird, Designer Fund, and others. Interfere is already running in production with design partners, which means the work you ship will immediately help real teams find and fix the failures costing them users today. The category is still being defined, but the product to fill this gap is inevitable, and the company that gets there first will own how the next decade of teams ship software....
