Backend Software Engineer (Rust)

Location Remote / Hybrid Greater Toronto Area

We are looking for a Backend Software Engineer with strong 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.
