Build the substrate for sovereign AI.
A very small team working on hard cryptography, confidential compute, and developer experience for the agent economy.

Backend Engineer, Rust (Gateway & Billing)
Own the metering path of a production Rust gateway (axum, sqlx, Postgres): pre-authorization holds, an append-only credit ledger, signed receipts, idempotent settlement. Correctness bugs here are money bugs. You should enjoy proving code right, not just shipping it.

Senior Backend Engineer, Rust (Confidential Compute)
Build the confidential sandbox: a measured Intel TDX runner CVM, DCAP quote verification, per-job response binding, sealed secret delivery. You have shipped Rust systems software and are comfortable reading TEE specs; prior enclave work is a plus, not a requirement.

Three principles.
We sell trust, not features.
Every line in the privacy path holds the cryptographic guarantee or it doesn't ship.
Calm, not loud.
Infrastructure people don't want confetti. We write code and copy with the same restraint.
Crypto-native, not crypto-bro.
On-chain in service of decentralization, not speculation. Platform economics stay dollar-denominated: Sable is always priced in dollars, the SABL community token's only role is an optional way to pay, and supply is never paid in emissions.
No fit? Write anyway.
What you do, what you'd build, a link or two. We read every email.
