Post-Quantum Cryptography Solutions Architect

As a Principal Solutions Architect at Quantum Sky, you drive the technical execution of post-quantum cryptography offerings. You bridge strategy and delivery by translating customer requirements and organizational roadmaps into actionable engineering backlogs, driving business development through proposal responses and product demonstrations, and directly advising customers on their cryptographic transition and migration planning.

What you'll do

• Partner with the Director to guide development teams in building out PQC product offerings
• Translate customer and market requirements into well-defined epics, user stories, and a prioritized development backlog
• Provide technical oversight to ensure implementations align with NIST PQC standards and sound cryptographic engineering practice
• Contribute technical and market insight to inform PQC offering strategy and roadmap
• Contribute technical responses including solution architecture to BAAs, RFIs, and RFPs
• Guide customers through PQC transition and migration planning, including cryptographic inventory, risk prioritization, phased migration roadmaps and action plans, orchestration, implementation, and continuous monitoring
• Assess and communicate cryptographic and key management risk
• Advise on prioritization frameworks for migration based on data sensitivity, system criticality, and crypto-agility

What you bring

• An advanced academic background: BS or MS in Cryptography, Computer Science, Computer Engineering, or a related field, with a solid working understanding of cryptographic and PQC algorithms
• 3+ years of experience in federal cybersecurity, including direct involvement in NSA/NIST pilots
• 5+ years of experience in encryption/secure systems engineering, PKI, and key management solutions, including 2-3 years of hands-on involvement in PQC migration planning or implementation
• Working knowledge of NIST PQC algorithms such as ML-KEM and ML-DSA, and how key material is generated, distributed, and consumed within cryptographic systems and cryptonets
• Demonstrated ability to communicate technical cryptographic concepts to both engineering teams and executive/business audiences, and to operate effectively across customer organizational levels
• Proven ability to curate and manage partners for inventorying, distributed key management, software-defined cryptography, and quantum-resistant solutions
• U.S. citizenship and eligibility for TS/SCI clearance

Nice to have

• Experience with distributed key management architectures and crypto-inventory tooling
• Experience with PQC deployments or PQC implementations in constrained/tactical DoD/IC environments
• Familiarity with AI/ML applications in cyber operations or PQC migration tooling
• Prior experience developing roadmaps, maturity models, or migration playbooks
• Publications, conference talks, or community contributions in PQC and applied cryptography
• Active security clearance

What we offer

• Salary range of $175,000-$215,000, based on skills, experience, education, certifications, and other factors
• Health, dental, and vision coverage
• 401(k) match
• Paid time off
• Short-term disability, long-term disability, and life insurance
• Referral bonuses
• Professional development reimbursement
• Parental leave
• Remote work, US-based
