Post-Quantum Cryptography Solution Architect (Customer Delivery)

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. 

The Rewards 

We are an international team of quantum technology experts and dedicated business creatives that are working to bring quantum-enabled solutions to the global market. Our brilliant team members enjoy a high degree of freedom working remotely or joining one of our office spaces. We have a vibrant, enthusiastic, passionate and creative culture driven by trust, excellence and continuous improvement. If you join the Terra Quantum team, you can expect:

Company description 

Quantum technologies have the potential to solve some of the world’s biggest challenges. There have been great advances in all areas of quantum technologies, and new fields of application are opened up every day. Hybrid computer systems that combine classic high-performance computing with quantum computers are already being used to develop solutions in sectors such as logistics, healthcare, finance, energy, automotive and aerospace. Quantum mechanical predictions are also used to obtain unprecedented precision in measurements, generate unbreakable codes, and form the basis of impenetrable communication networks. All these developments are happening right now, and they are happening at Terra Quantum. 

At Terra Quantum we are building the world’s leading Quantum Technology company. We offer customers world-class quantum technology expertise organized as “quantum-as-a-service”: hybrid quantum algorithms, quantum compute and quantum enabled security solutions. Through the proprietary quantum cloud, customers have access to a unique technology platform which provides a toolset to solve real-world challenges in the realms of machine learning, optimization and simulation, today. In 2022, the company closed its Series A financing round with a $75m fundraise. 

Quantum physics has, in some respects, parallels to the machine language of our computers-the zeros and ones into which our keyboard or touchscreen instructions are translated for execution in the computer-only on a larger scale: it is the machine language of the universe. The second quantum revolution is based on the control of individual quantum systems, such as individual atoms. We use quantum computers to solve currently unsolvable problems, simulate molecules and their interactions, find drugs for diseases that are not yet curable, find new materials, or make artificial intelligence stronger. Quantum is now. 

Terra Quantum is a future-focused quantum services and technology company working on making the second quantum revolution a reality. Terra Quantum’s activities span all areas, markets, and industries globally. 

• Our purpose is to pioneer quantum technologies to change the world for good,
• Our vision is to lead the quantum revolution and be the trailblazer in technology solutions, shaping a better future for humankind to thrive in, and
• Our mission is to unleash the power of quantum tech to deliver meaningful solutions today

Terra Quantum is an equal opportunities employer, committed to diversity, inclusion and employee well-being.
