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! ## Equal Opportunity Employer Qrypt is committed to creating a diverse environment and is proud to be an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, disability, age, or veteran status. If you have a disability and need assistance with our employment application process, please email us at info@qrypt.com to obtain assistance. ## About Qrypt ## Company Overview - **One-liner**: Qrypt provides quantum-secure encryption solutions designed to protect data from current threats and future quantum computing risks. - **Entity Type**: Private (Incubator/Accelerator – NVIDIA Inception Program) - **Headquarters**: New York, New York, United States - **Founded**: 2017 - **Founders**: Kevin Chalker (CEO) and Denis Mandich (CTO) ## Core Business - **Primary industry**: Cybersecurity / Quantum-Secure Encryption - **Target customers**: B2B – enterprise, government, critical infrastructure, and industries vulnerable to intellectual property theft - **Mission**: "To protect and defend our collective privacy from exploitation" and help customers "take back your privacy forever" ## Products & Services - **Quantum Entropy-as-a-Service**: Cloud-based delivery of true random numbers for cryptographic key generation. - **Quantum Entropy Appliance**: On-premises hardware that generates quantum entropy for high-security environments. - **Quantum-Secure IPsec Gateway**: Encrypted network communication that resists quantum computer attacks. - **Digital Quantum Key Distribution (DQKD)**: Software-based key distribution using quantum principles without dedicated fiber. - **Q-Isolate**: A solution that isolates and secures sensitive workloads using quantum-derived keys. Qrypt holds 10+ patents covering resonant cryptography, multi-source entropy aggregation, and key management. ## Market Standing - **Valuation**: Not publicly disclosed - **Key Metric**: Headcount of ~21 employees (as of 2026, -11.1% YoY); total funding not disclosed, but backed by the NVIDIA Inception Program - **Notable Investors/Partners**: NVIDIA Inception Program; strategic partnerships with Mattermost, ITSEC Asia, AIC, and U.S. national labs - **Growth Signals**: Recent board appointments (Ralph Goff, former CIA senior executive; Nick Lippis, ONUG co-founder); joint development program with Mattermost for quantum-secure end-to-end encryption; expansion into critical infrastructure and Indonesian markets ## Competitive Advantages - **Mathematically proven unbreakable encryption**: Qrypt’s algorithm is claimed to be the only one proven secure even in theory, not just against known attacks. - **Quantum-ready today**: Solutions are designed to resist both classical and quantum attacks, eliminating the need for future migration. - **Patented technology**: 10+ patents in resonant cryptography, entropy aggregation, and key management. - **Team pedigree**: Founders and team include experts from academia, industry, and government (e.g., chief cryptographer Yevgeniy Dodis). ## Strategic Focus - **Critical infrastructure & government**: Targeting sectors most vulnerable to cyberespionage and quantum threats. - **FIPS compliance & standards**: Building solutions that meet U.S. government security standards (e.g., AIC’s FIPS-compliant platform powered by NVIDIA BlueField-3 DPU). - **Joint development**: Collaborating with platforms like Mattermost to embed quantum-secure encryption into widely used communication tools. - **Global expansion**: Partnerships in Asia (ITSEC Asia) and ongoing work with U.S. national labs. ## Why Work Here - **Culture & mission**: "Eternal Encryption" – a strong sense of purpose in defending digital privacy against quantum threats. Team is composed of cryptography, physics, and security experts. - **Work arrangements**: Hybrid and in-office roles available. Offices in New York City (HQ), Germantown (MD), and Austin (TX). Recent postings include in-office (Germantown) and hybrid (Austin) positions. - **Perks & benefits**: - Company equity - Generous parental leave - Health insurance, dental, FSA - 401(K) and disability insurance - Free snacks and drinks - Customized development tracks - **Engineering culture**: Stack includes Python, TypeScript, React, Docker, Kubernetes, Terraform, Bazel, Verilog/VHDL, and more.
