About Benchify
Benchify is building the reliability layer for AI-generated code. Today, we make sure dynamically generated code always builds. Tomorrow, we’ll add correctness and security guardrails so any code written by an LLM just works. Our vision is instant, self-healing code pipelines — where AI-generated software not only compiles, but runs reliably and securely without human babysitting.
About the role
Skills: Distributed Systems, Docker, Amazon Web Services (AWS)
The Role
We’re looking for a Founding Engineer who loves containers, infra, and DevOps. Your work will touch the critical path: packaging, scaling, and running code in dynamic environments where milliseconds matter. You’ll also get to influence how we build everything — from product APIs to culture. We are a small team, and you will get to touch every part of the product, work directly with customers, and ship new features every day. It is completely fine if you’ve never done any static analysis before. Max, our CTO, has a PhD in theoretical computer science and can get you up to speed very quickly. We are looking for grit, creativity, and the ability to pick up new skills quickly.
What you’ll do
Design and optimize containerized environments that can boot, run, and heal code in milliseconds.
Build infra that validates, repairs, and runs AI-generated code at scale.
Work across the stack when needed — but especially on the dev/ops side of things.
Talk to customers and ship features that solve real-world problems.
Help shape our engineering culture (lots of esoteric memes).
You might be a good fit if you:
Have strong experience with containers, runtimes, and DevOps tooling (Docker, K8s, Fly.io , OCI images, AWS, etc.).
Enjoy making infra faster, leaner, and more reliable.
Are fluent in TypeScript, Node.js, or Python .
Especially if you know a decent amount about the underpinnings of these languages – e.g., if you can explain why uv is faster than pip, if you have strong opinions on Parcel versus Vite, or if you feel that Python “doesn’t really have a type system”.
Care about performance and correctness, not just “works on my laptop.”
Are curious about compilers, testing, or program analysis (bonus points).
Like working in fast-moving, small-team environments with big ownership.
Why join Benchify?
Impact : You’ll be one of the first engineers, shaping the infra that powers self-healing code.
Fun : We’re serious about building, but not about ourselves. Expect plenty of bad puns and half-baked analogies.
Trajectory : YC-backed, funded, early customers.
Upside : Competitive salary + meaningful equity.
Details
Location: In person in San Francisco or New York City
Compensation: Competitive salary + meaningful equity

Technology
Benchify is built on an unholy alliance of static analysis and techniques from program synthesis / program repair. Our product is high performance (it does a lot in a short amount of time) which means we do a decent amount of parallelization and optimization work. We care deeply about algorithm design and clever hacks. If you enjoy HPC stuff, static and dynamic analysis, and doing unspeakable things to compilers and bundlers, you’ll enjoy working at Benchify.
