Backend Engineer

About the role

You will own backend systems where confidentiality and integrity matter. Client repos, findings, and report drafts need APIs that are boring in the best way: typed, observable, and hard to misuse.

Responsibilities

• Design and implement Node.js + TypeScript services and APIs for core product workflows
• Encode authorization, policy checks, and audit trails as first-class system behavior
• Build durable job/orchestration paths for settlement and attestation with clear failure semantics
• Define service boundaries, schemas, and SLIs that scale with design-partner load
• Harden operational readiness: logging, metrics, tracing, and runbooks for critical paths

Requirements

• Senior Node.js experience building production APIs and background processing
• Strong grasp of data modeling, consistency tradeoffs, and idempotent design
• Security-aware engineering — authn/authz, secrets handling, and least privilege
• Comfort owning services through production issues, not just green-path delivery
• Ability to write crisp interface contracts for frontend and protocol consumers

Nice to have

• Experience with Postgres or similar systems under transactional workloads
• Familiarity with queues, workers, and exactly-once / at-least-once patterns
• Background in payments, custody, KYC/AML tooling, or regulated APIs
• Interest in integrating with MPC, HSM, or enclave-backed signing flows

Benefits

• Meaningful founding equity
• Flexible PTO and remote-first culture
• On-call stipend when production coverage begins
• Home-office stipend and hardware signing kit
• Health coverage as we formalize benefits
• Cloud and tooling budget for serious local/prod parity
