Senior Rust Developer

Silence Laboratories builds cryptographic infrastructure for financial institutions, payments networks, custodians, and other security-sensitive customers. We are hiring a Senior Rust Developer to build the software stack that turns our cryptographic protocols into production systems: backend services, MPC orchestration layers, SDKs, APIs, bindings, developer tooling, and customer-facing integration surfaces.

This role sits between cryptography research and enterprise deployment. You do not need to be a cryptographer, but you do need to care deeply about correctness, auditability, reliability, and clear interfaces. Your code will be read by engineers, cryptographers, security auditors, and customers who operate in regulated environments.

• Build and maintain Rust services, libraries, SDKs, and APIs used in production customer integrations.
• Translate protocol specifications into clean, testable, auditable implementation patterns.
• Design networking and orchestration layers for multi-party cryptographic protocols.
• Build and harden cross-platform bindings, including TypeScript, Kotlin, Swift, Python, WASM, or similar targets where needed.
• Improve developer experience through API design, documentation, examples, integration guides, and tooling.
• Partner with cryptography, product, solutions, and customer teams to make complex cryptographic operations deployable at enterprise scale.
• Write comprehensive tests, including unit, integration, property-based
