Engineer, Protocol & SDKs

Remote · Full-time · Senior IC

Own one or two SDKs end-to-end (Python, TypeScript, Go, or Rust), harden the verifier and signed-receipt path, and take Registry reliability seriously. Senior backend engineer comfortable with cryptographic primitives (signatures, DIDs, JWT/COSE-style formats), API design, and treating security as a normal engineering constraint, not a research project.
