Job summary

Qrypt is looking for a Backend Software Engineer to build the services behind our quantum security products. You will write and ship backend software — primarily in Rust — that moves quantum entropy and keys, powers our entropy-as-a-service platform, and makes our appliances work reliably at scale.

You will use AI-assisted development tooling as a core part of how you work, while owning the correctness and quality of everything you ship.

Qualifications

• Bachelor's degree in Computer Science or a related field, and/or relevant work experience.
• 3+ years building and shipping backend software.
• Proficiency in Rust, or strong systems-programming experience with a demonstrated ability and eagerness to work primarily in Rust.
• Working familiarity with C++ and Python.
• Solid grasp of backend fundamentals: APIs, services, concurrency, testing, and Linux.
• Fluency with AI and agent-assisted development, and the judgment to apply it where it adds real leverage.

Responsibilities

• Design, build, and test backend services and APIs, primarily in Rust, with some C++ and Python.
• Work on software that delivers quantum entropy and keys reliably and securely.
• Write well-tested, maintainable code and participate in design and code review.
• Use AI-assisted development tooling to accelerate work while owning correctness and quality.
• Help shape how the team adopts AI-assisted development as tooling matures.
• Develop understanding of quantum RNG, cryptography, and network security.
• Collaborate with hardware, product, and other engineers to ship end-to-end.
