Steel is building open-source browser infrastructure for AI agents & apps. We make it easy for AI engineers to ship products that interact with the web using our Sessions API - An API that controls fleets of browser sessions in the cloud while we handle everything from scaling to antibot and more.
Our tech stack:
- Frontend: Vanilla React + TailwindCSS + Shadcn, built with Vite, deployed on Vercel
- Backend: Fastify, Node.js, Zod, NATs, Drizzle with Redis, PostgreSQL, and S3
- Infrastructure: Pulumi, Go, Firecracker VMs, Docker
- Languages: Mostly Typescript, Rust, Go
With over 6,000 GitHub stars, dozens of paying customers, and millions of sessions served, we grew our platform 50x in 2025 purely through word-of-mouth and our open-source community. Backed by world-class investors, we're building a small, talent-dense team that's shaping the future of how humans & agents interact with the internet.
Current roles (all roles include competitive comp + equity):
- Infrastructure Engineer: Design, optimize, and scale our browser VM infrastructure
- Applied AI Engineer: Build on agent frameworks, integrations, and real-world AI use cases
- Founding Growth Lead: Own the growth machine to turn insane organic traction into a category-defining brand
- Founding GTM Lead: Be our first sales hire, closing deals with AI startups transforming entire industries

EQTY Lab is focused on emerging governance and security paradigms for AI infrastructure. Our primary focus is verifiable computing using cryptographic capabilities to identify and govern agent behavior.
We're also focused on helping the industry advance with frontier tooling. From requesting the hooks feature in Claude Code, to building our own open-source integrated capabilities such as https://github.com/eqtylab/cupcake - we will continue to explore and share the things we develop for coding agents or any frontier tooling enterprise is quickly adopting.
We're seeking software engineers across the full stack. To include,
- engineers interested in governance tooling - sdk writing in TypeScript or Rust - or engineers with cryptographic security domain experience - or deeper hardware level focus (platforming on Kubernetes - confidential computing, custom firmware as it relates to GPUs). For all of this, we're seeking experienced devrel to help us communicate and build tooling the right way.Please email me directly: ramos@eqtylab.io
