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.
Job Details
Responsibilities
- 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)
Requirements
- A 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 reason about threat models, blast radius, and key custody as a habit, and you write code that holds up to security-critical review
- Comfortable with applied-cryptography fundamentals (public-key crypto, signatures, key management). You do not need to be a cryptographer, but you can reason about it and learn fast
- Solid on distributed systems and API design: idempotency, failure modes, and clean service boundaries
- Operationally mature: Kubernetes, observability, and incident response are not foreign to you
- Clear written communicator (design docs, decision records) who thrives in a collaborative, review-heavy culture
