Senior Staff Backend Engineer

The Vault is seeking a Senior Staff Backend Engineer to contribute to its crypto custody platform, which serves both institutional and retail clients. This role involves designing and implementing complex backend systems, focusing on critical components such as policy engines, signing orchestration, and key lifecycle workflows. Candidates should have experience with high-load, multi-tenant SaaS systems, distributed systems, and security practices, including mTLS and audit-ready data models. The position emphasizes technical leadership without people management responsibilities, requiring the ability to drive initiatives through code and documentation. Familiarity with AI tools for code generation is also important, as the team values critical evaluation of AI outputs. The role is suited for engineers who can navigate either security-critical areas or faster-moving integrations and APIs. While the advert does not specify the employment type or working arrangement, it highlights the need for strong relational database skills, particularly with Postgres or similar technologies. This position is ideal for experienced engineers looking to make a significant impact in a rapidly evolving field.
