Senior System Engineer (Go) - Metal Platform

We're building the platform that orchestrates how software moves across our entire server fleet. You'll work in Go on the control-plane services driving deployments, and shape the Linux image and boot path that safely brings servers from power-on to running production software.

If you want to: •

Design and build Go services for fleet-wide deployment, configuration, and lifecycle management;

•

Work on the Linux image and boot path used by servers in the fleet;

•

Contribute to the cryptographic protocols and machine-attestation work behind it;

•

Help keep the system's security properties verifiable as it evolves.

And you can check off: •

Strong Go and a track record of shipping production backend services;

•

Solid Linux internals: kernel boot, initramfs, networking stack;

•

Comfortable with modern cryptographic primitives and authn building blocks (mTLS, OIDC, signature schemes);

•

Security-first mindset: you think in threat models, key rotation, and blast radius.

Bonus points if you: •

Have worked with hardware roots of trust or measured boot;

•

Have shipped supply-chain primitives (reproducible builds, SBOMs, artifact attestation);

•

Have used formal-methods tools to reason about protocols or systems.
