Backend Software Engineer (Rust)

About the Role

We are looking for a Backend Software Engineer with strong Rust expertise to build secure, scalable, and high-performance services for our Next-Gen Human Identity (NHI) Platform.

You will play a key role in designing and implementing backend services, APIs, and cryptographic workflows, working closely with the Software Architect, Frontend Engineer, and Cloud & Deployment Engineer.

This role requires someone who is both strong in systems programming and backend development, and comfortable working on security-focused systems (TLS, certificates, identity).

Responsibilities

What you’ll own.

• Backend development
• Design and build high-performance backend services in Rust.
• Develop REST/gRPC APIs for certificate management, identity workflows, and system operations.
• Implement asynchronous and concurrent systems using Rust best practices.
• Write clean, maintainable, and testable code.

• Security & cryptography
• Work with TLS/SSL, X.509 certificates, and secure communication flows.
• Implement or integrate certificate lifecycle management (issuance, rotation, revocation).
• Ensure secure handling of keys, secrets, and authentication flows (mTLS, token-based).

• Cloud-native & distributed systems
• Build services designed for containerized environments (Docker).
• Work with Kubernetes-based deployments.
• Collaborate on scalability, observability, and reliability.
• Integrate with cloud services (AWS, Azure, or GCP).

• Data & persistence
• Design and implement PostgreSQL schemas.
• Optimize queries and ensure performance at scale.
• Handle transactional workflows and consistency.

• Collaboration
• Work closely with the Software Architect on system design.
• Partner with the Frontend Engineer on API contracts.
