Description

Own backend services and the cryptographic recovery and trust-model systems that support ZeroDev’s embedded wallets.
Build Go services that broker wallet creation, authentication, and signing at scale.
Design and implement key recovery mechanisms and distributed trust models using committee-based key splitting and secret sharing.
Work with trusted execution environments to reconstruct and operate on key material under hardware isolation and remote attestation.
Integrate user authentication and signing flows such as passkeys, OAuth, OTP, sessions, and 2FA.
Integrate with third-party signing providers, including authorization, policy flows, scoped credentials, and quorum-based approvals.
Write design docs and decision records, and partner directly with external security auditors on reviews and remediation.
Harden security-critical systems and ship code that meets a high review bar.
Operate production services on Kubernetes, including observability, alerting, secrets and certificate management, and on-call support.
Apply required compliance controls such as sanctions screening and PII-safe handling.

Requirements

Strong backend engineering experience shipping and operating production services in Go, or another adjacent systems language with willingness to go deep in Go.
Security-first mindset with the ability to reason about threat models, blast radius, and key custody.
Applied cryptography fundamentals, including public-key cryptography, signatures, and key management.
Solid understanding of distributed systems and API design, including idempotency, failure modes, and service boundaries.
Operational experience with Kubernetes, observability, and incident response.
Clear written communication skills for design docs and decision records.
Comfort working in a collaborative, review-heavy environment.
TEE experience with AWS Nitro Enclaves, Intel SGX/TDX, or similar, including attestation and enclave key handling, is preferred.
Threshold cryptography or MPC experience, such as DKG, FROST, verifiable secret sharing, or resharing, is preferred.
Account abstraction experience with ERC-4337, EIP-7702, or embedded/non-custodial wallets is preferred.
Experience integrating with custody or signing providers such as Turnkey or Fireblocks, or having built one, is preferred.
HSM, YubiKey, PIV, or secure-element integration experience is preferred.
Experience receiving and remediating findings from a third-party security audit is preferred.
Experience with WebAuthn/passkeys, OAuth/OIDC, and the Go crypto ecosystem is preferred.

Benefits

Remote-first global workforce with a New York office.
Annual company offsite plus team onsites.
Professional reimbursement program for conferences, certifications, and similar development expenses.
Medical, dental, and vision coverage for U.S. employees and some other countries.
401(k) retirement plan with company match for U.S. employees.
