Offchain Labs

• The Developer Platform team builds KMS, the key-management and signing service behind ZeroDev's embedded wallets (smart-account / account-abstraction wallets that app developers drop into their products). It is non-custodial: end users control their keys, and the service orchestrates secure creation, authentication, and signing on top of a third-party signing provider. This is security-critical infrastructure, externally audited, with a high review bar. You will own backend services and the cryptographic recovery and trust-model machinery around them on a small, high-ownership team, and help grow the platform from interactive consumer wallets toward programmatic and automated signing and programmable transaction policy. • Go backend services that broker wallet creation, authentication, and signing at scale. • Key recovery and the committee trust model: distributed key generation and secret sharing that keep the service non-custodial, with recovery authority split across independent committees so no single party ever holds a user's key. • Trusted Execution Environments: reconstructing and operating on key material under hardware isolation and remote attestation. • Authentication and signing-provider integration: the user-facing auth methods that gate signing (passkeys / WebAuthn, OAuth, OTP, sessions, 2FA), and integrating with a third-party signing provider (authorization and policy flows, scoped credentials, quorum / consensus approvals). • Security review and hardening: writing design docs and decision records, working directly with external security auditors, and turning a high review bar into shipped code. • Production operations on Kubernetes: observability and alerting, secrets and certificate management, on-call, and the compliance controls the domain requires (sanctions screening, PII-safe handling)
