Cryptography
Applied Cryptographer, Credential Issuance
Own the issuance path for short-lived, scoped credentials — the moment an agent is trusted to act.
- team: Cryptography
- location: Remote (EMEA)
- type: Full-time
- level: Senior
The role
Every agent gets a distinct identity and credentials that live for minutes, not months. You own the cryptography that makes those credentials unforgeable, revocable, and cheap to issue at volume.
This is applied work: correctness, key handling, and performance under load, not papers.
What you will do
Design the issuance and rotation flow for scoped, short-lived credentials.
Choose and defend the primitives — signatures, attestations, and revocation — against a written threat model.
Drive the path from anomaly to full revocation down toward seconds.
Review the engineering team's use of the crypto surface you own.
What we look for
Hands-on experience shipping cryptographic systems in production — PKI, token issuance, HSMs, or credential frameworks.
You know where implementations leak and you test for it.
You can explain a trade-off between security and latency to the team making it.
