Solution Architect – Post-Quantum Cryptography

We are hiring a Solution Architect to support customer delivery of post‑quantum cryptography (PQC) and cryptographic agility solutions. This role focuses on practical delivery, integration and customer‑facing technical work while contributing insights to our broader PQC strategy.

The Solution Architect will operate independently in day‑to‑day engagements with customers, coordinating closely with the Lead Security Engineer, who serves as the primary contact for the Commercials team and overall delivery lead.

The role is remote within the USA with some travel for customer meetings and project delivery.

Qualifications – Required

• Bachelor's degree in computer science, cybersecurity, or related field.
• Minimum 4+ years of experience in cryptography, secure systems integration, or professional services.
• Hands‑on experience with major crypto libraries (OpenSSL, BoringSSL, wolfSSL, liboqs, etc.).
• Proficiency in C/C++ and Python; Java, Go and/or Rust is a plus.
• Familiarity with all three major cloud platforms (AWS, Azure, GCP).
• Experience with hybrid cryptography, KMS/HSM integration and secure protocol deployment.
• Proven customer‑facing experience, ideally in consulting or professional services.
• Experience working with government or defense clients; eligible to obtain U.S. security clearance.

Qualifications – Desired

• Familiarity with PQC standards development (NIST, ETSI, EU initiatives).
• Familiarity with NIST Risk Management Framework (RMF).
• Experience presenting at conferences, workshops or technical forums.
• Exposure to benchmarking PQC in IoT/IoBT or DDIL environments.
• Knowledge of compliance and regulatory frameworks relevant to cryptography.
• Publications, white papers or patents related to applied cryptography.
• Ability to translate cryptographic strategy into plain business language.

Responsibilities – Overall

• Deliver customer projects across the PQC lifecycle, from cryptographic assessments to hybrid solution deployment.
• Design and implement cryptographic solutions involving PQC algorithms (Kyber, Dilithium, SPHINCS+), classical interoperability and crypto agility.
• Integrate solutions for key management (KMS, HSM, cloud environments) and protocol‑level architecture (TLS, VPN, IoT/IoBT).
• Benchmark and validate cryptographic solutions in constrained environments (IoT, DDIL, low‑bandwidth networks).
• Collaborate with product engineering to translate field experience into product improvements.
• Track U.S. (NIST) and EU PQC regulatory developments to inform customer guidance.
• Support pre‑sales and proposal work as a technical contact, in coordination with the Lead Security Engineer and Commercials team.

Responsibilities – Day‑to‑Day

• Engage in customer meetings to gather requirements and provide technical insights.
• Conduct workshops, briefings and technical sessions for customer stakeholders.
• Participate in conferences, thought‑leadership activities and standards discussions when relevant.
• Prepare technical documentation (bills of materials, migration playbooks, integration guides) for delivery projects.
• Collaborate with internal teams to ensure scalable, compliant and production‑ready solutions.
• Provide ongoing technical support and advocacy for deployed solutions.

Rewards & Benefits

• Opportunity to work with some of the brightest minds in pioneering quantum technologies.
• Gain knowledge of cutting‑edge technology developments in science & engineering.
• Part of a globally leading technology firm at the forefront of quantum science.
• Welcoming, friendly, and professional colleagues.
• Personal development plan with clear goals for advancement.
• Competitive salary and flexible working arrangements.
• Diverse and supportive atmosphere that encourages innovation and initiative.
