Post-Quantum Cryptography Architect at Terra Quantum

Job description

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 but will coordinate closely with the Lead Security Engineer, who serves as the primary contact for the Commercials team and overall delivery lead. 

You will guide customers through phased projects, beginning with cryptographic bill of materials and asset scanning, and extending to PQC migration planning, hybrid solutions, and deployment of our crypto-agility platform. Your overall objective will be to help customers achieve quantum-safe compliance, resilience, and regulatory readiness.  This role requires deep technical expertise, strong consulting skills, and the ability to communicate complex cryptographic concepts to diverse audiences. 
 
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/expertise with major crypto libraries (OpenSSL, BoringSLL, 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. 

 

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. 

 

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.
