Security
Security Engineer
Remote (Global) Full-time $130,000–$180,000 USD / yr 0.5–1.5% equity
This role opens after our pre-seed round.
Everything below — scope, salary band, equity — is real and current. Join the pipeline at the bottom and you will hear from us first, before the role is ever posted publicly.
Own the security posture of a payments company: smart-contract review, key management (2-of-2 MPC with passkey-bound shares), API hardening and incident response.
What you will own
- Audit and threat-model the settlement contracts before external audits do.
- Own the MPC custody architecture and the WebAuthn ceremony end to end.
- Build the abuse pipeline: rate limits, anomaly detection, scam-pattern ML.
- Run responsible disclosure and write the post-mortems we publish.
What we need to see
- 4+ years in security engineering, with real findings you can talk about (CVEs, audit reports, bounties).
- Deep familiarity with EVM attack classes: reentrancy, signature replay, approval phishing.
- You have operated production incident response, not just tabletops.
Nice to have
- Published security research.
- Experience with HSMs or MPC libraries.
