Senior Software Engineer

About This Opportunity

We are representing a confidential deep-tech semiconductor organization specializing in advanced cryptography and secure embedded systems. They are seeking a Senior Software Engineer to design and implement the next generation of classical and post-quantum cryptographic solutions for embedded platforms.

This role offers the opportunity to work on cutting-edge technology in a rapidly expanding segment of the industry, collaborating directly with technical leadership on secure software implementations for ARM and RISC-V architectures.

The position is based in the UK, Netherlands, Spain, or Belgium, with occasional travel to company offices required.

Responsibilities

• Design, implement, and test classical and post-quantum cryptographic primitives with emphasis on functional correctness, interoperability, and optimized performance across software environments
• Develop and integrate cryptographic solutions on hardware platforms, including FPGA and hardware cryptographic coprocessors, focusing on acceleration and secure implementation on ARM and RISC-V architectures
• Harden cryptographic implementations against side-channel analysis, fault injection attacks, and other physical or logical threats through constant-time design and countermeasures
• Ensure integration with cryptographic system and application APIs, such as GlobalPlatform, ARM Platform Security Architecture, and Linux Kernel drivers
• Collaborate with cryptographers, security engineers, and cross-functional teams to review, validate, and harden cryptographic implementations
• Contribute to performance benchmarking and optimization across multiple platforms
• Participate in design and code review meetings to improve cryptographic software quality, architecture, and development processes
• Perform and support security-focused code reviews, including static and dynamic analysis, and apply formal methods such as model checking where applicable
• Maintain and enhance existing cryptographic software, ensuring robustness, security, and performance across supported platforms
• Support compliance with relevant security standards including FIPS, ISO/IEC, and NIST PQC
• Participate in threat modeling and risk assessments related to cryptographic software

What We're Looking For

Required Qualifications:

• Master's or PhD degree in computer science, mathematics, or related field, with strong background in cryptography or computer security
• Proficiency in C and Assembly, with focus on resource-constrained, bare-metal environments
• Familiarity with classical and post-quantum cryptographic algorithms, including NIST PQC candidates
• Solid understanding of NIST and FIPS publications and compliance requirements
• Excellent problem-solving and debugging skills

Preferred Qualifications:

• Experience with secure coding practices and countermeasures against implementation attacks
• Solid understanding of side-channel attacks (timing, power, electromagnetic), fault attacks, and corresponding mitigation strategies
• Hands-on experience with security certification frameworks such as FIPS 140-3, SESIP, PSA Certified, or Common Criteria
• Ability to read and implement specifications from cryptographic research papers
• Experience with Rust is a plus
• 2+ years of professional experience in cryptographic software engineering preferred; however, seniority is assessed primarily based on depth of knowledge, hands-on experience, and problem-solving skills
