Senior Software Engineer

Work with usClearance for AI that has to hold when challenged. Seal is the production gateway behind that claim. Join the engineering and research work that makes the record hold when challenged.Dublin

• permanent, full-time
• remote or blendedWhen an AI system makes a decision that matters, there is usually no way to prove afterwards what it actually did. You would work on the signing service that fixes that, and on the open specification behind it: Ed25519 signing, canonical serialisation that has to produce byte-identical output in Python and TypeScript, an append-only Merkle log built to RFC 6962, and two reference verifiers kept behaviourally identical by a conformance suite.You
• Strong in Python and TypeScript, and you like cryptography and specifications.
• You enjoy working out how things break, because most of this job is reasoning about an adversary who controls the record.

• paid internship
• full-time or part-time by agreementWork on Seal, the production gateway that clears AI requests and signs a record of the decision before the model call. You will own a bounded piece of backend or infrastructure work, from design through deployment, on a system already live.You
• Comfortable in Python, and you care that code reads as cleanly as it runs.
• Ready to make a well-defined part of a production system materially better.

Dublin or remote within the EU and Switzerland

• paid research internshipThis is research, not a deployed gateway feature. Explore how a proof can show that a policy held without dumping sensitive digests, then turn the useful parts into prototypes against the open ATTESTATION-v1 format and public verifiers.You
• A strong mathematics or computer-science foundation, with curiosity about elliptic-curve cryptography and proof systems.
• Familiarity with Groth16, Schnorr proofs, Rust, Python, or circom is useful but not required.
