About this role

Qrypt's mission is to protect the world's data and restore privacy. Qrypt hardens cybersecurity and future-proofs encryption against quantum attacks by eliminating key transmission. Qrypt's unique technology independently generates symmetric keys at multiple endpoints for critical workflows today. We are a passionate team of engineers, physicists, and cryptographers committed to transforming the way the world safeguards data and communications! 

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. 

What you'll do

    • Design, build, and test backend services and APIs, primarily in Rust, with some C++ and Python. 

    • Work on the 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 and agentic development tooling to accelerate your work while owning the correctness and quality of everything you ship. 

    • Help shape how the team adopts AI-assisted development (instruction conventions, review standards) as the tooling matures. 

    • Develop an understanding of the domain (quantum random number generation, cryptography, network security) to build and validate our products. 

    • Collaborate with hardware, product, and other engineers to ship end-to-end. 

What you'll need

    • Bachelor's degree in Computer Science or a related technical field, and/or relevant work experience. 

    • 3+ years building and shipping backend software. 

    • Proficiency in Rust, or strong systems-programming experience (C, C++, Go) 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 — reviewing, correcting, and taking full ownership of AI-generated work.  

    • Strong written and verbal communication skills. 

    • Must be authorized to work in the United States. Qrypt does not provide visa sponsorship for this role. 

Nice to have

    • Experience with cryptography, security, or networking systems. 

    • Experience with high-reliability or performance-sensitive services. 

    • Familiarity with Linux systems programming and packaging/deployment. 

Benefits & Perks

    • Competitive Pay & Equity participation 

    • Comprehensive health, dental and vision coverage 

    • 401(k) match 

    • In-office lunch and snacks 

    • The opportunity to be part of a company solving one of the most critical technology challenges of our time!
