Offchain is the technical backbone for global companies, delivering protocol-level breakthroughs for the transition to secure, programmable onchain infrastructure. Backed by Lightspeed and Redpoint.
About the role
The Developer Platform team builds KMS, the key-management and signing service behind ZeroDev's embedded, non-custodial wallets. These are smart-account / account-abstraction wallets that developers integrate directly into their applications. End users retain control of their keys, while KMS security orchestrates wallet creation, authentication and signing on top of a third-party signing provider.
What they're looking for
- Strong backend engineer who has shipped and operated production services in Go (or an adjacent systems language and is eager to go deep in Go)
- Security-first by default: You naturally think about threat models, blast radius and key custody, and write code that holds up to security-critical review
- Solid on distributed systems and API design: You’re comfortable reasoning about idempotency, failure modes and clean service boundaries
- Operationally experienced: You’ve worked with production infrastructure and are comfortable with Kubernetes, observability and incident response
- Clear written communicator: You can explain technical decisions through design docs and decision records, and work effectively in a collaborative, review-heavy environment
- Trusted Execution Environments (TEE) such as AWS Nitro Enclaves, Intel SGX / TDX or similar
