We are looking for a Backend Software Engineer with robust Rust expertise to build secure, scalable, and high-performance services for our Next-Gen Non-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.

- 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.
- Work closely with the Software Architect on system design.
- Partner with the Frontend Engineer on API contracts.
- Partner with the Cloud Engineer on deployment and runtime concerns.
- Contribute to technical discussions and design decisions.

Required Skills

What you'll bring day one.

Core backend & Rust

- 3 to 6 years of backend development experience.
- Strong proficiency in Rust.
- Experience with async programming (tokio, async/await).
- Experience with Rust web frameworks (Axum, Actix, Warp).
- Solid understanding of ownership, concurrency, and memory safety.
- Experience building RESTful or gRPC APIs.
- Understanding of microservices architecture.
- Ability to design clean, versioned APIs.

Database

- Strong experience with PostgreSQL.
- Knowledge of indexing, query optimization, and schema design.

Cloud & DevOps awareness

- Experience with Docker and Kubernetes basics.
- Familiarity with CI/CD pipelines.

Security awareness

- Understanding of TLS/SSL fundamentals.
- Secure coding practices.
- Experience with certificate management is a strong plus.

Nice to Have

- PKI systems, certificate authorities, ACME protocol.
- KMS / HSM integrations.
- Identity & access management systems.
- Next.js frontend integration exposure.
- Experience in security or infrastructure platforms.

Why Join Us

1. 01 Work on a cutting-edge security and identity platform.
2. 02 Solve real-world cryptographic and infrastructure challenges.
3. 03 High ownership and impact in a growing team.
4. 04 Opportunity to work across Rust, cloud, and security domains.
