About the Role
The Vault, an MPC-based crypto custody platform for institutional and retail customers. We run threshold signing with non-extractable key shares across HSM and Ledger hardware, support a growing surface of chains and assets, and are pushing toward post-quantum readiness and SaaS-grade scale. Series A is ahead, the 2026 productized launch is in flight, and we publish original cryptographic research alongside the product work.
● Build end-to-end product features across Go backend and React frontend
● Design backend services using DDD patterns (bounded contexts, aggregates, domain events), clean layering, and pragmatic architecture
● Implement data models and migrations on PostgreSQL, using GORM where appropriate (and raw SQL when it’s the right tool)
Key Responsibilities
- ● Build and maintain REST APIs (and webhooks/event-driven workflows where needed)
- ● Implement frontend flows in React (TypeScript preferred): dashboards, admin workflows, status lifecycles, audit views
- ● Ensure correctness and observability: structured logging, metrics, tracing, and production-ready error handling
- ● Contribute to security fundamentals: RBAC, least-privilege access, safe secrets handling, and audit trails
