The Role
You’ll own product and infrastructure security across Squads, working closely with our Head of Security, CTO, and engineering leads across Multisig, Altitude, Fuse, and the infrastructure that powers them. That means being in the room when systems are designed, reviewing code before it ships, and driving every finding to verified closure.
This is a hands-on role. You’ll read code, write threat models, and build the tooling and standards that make the secure path the default as engineering grows. We’re looking for a senior practitioner who can tell engineers what to fix and why, and hold the line on what matters without slowing the team down.

Why This Might Be Interesting
Most product security roles sit downstream of engineering, reviewing what’s already been decided. This one sits in the room. You’ll shape how a self-custody platform, a business account, a consumer app, and the infrastructure under all of them get built, across Solana programs and traditional backend services alike.
The stakes are concrete: a missed authorization check here moves money. You’ll work directly with our Head of Security and CTO, with the ownership to build the product security program while operating it.
