Job summary

The French Sourcer is seeking a Solution Architect, Hardware & Software Security in Aix-en-Provence to own the end-to-end security architecture from silicon to cloud. You will define specifications, drive cryptographic choices, and guide multi-disciplinary teams to meet strict security and performance requirements.

You'll balance innovation with stability, manage a long-term roadmap, and collaborate with sales on RFPs, while ensuring compliance with security standards and certifications.

Qualifications

• 10+ years of hands-on technical experience in secure systems.
• Strong C/C++ development skills for constrained environments: bare-metal, RTOS, embedded Linux or secure operating systems.
• Deep knowledge of hardware security principles: secure boot, attestation, key lifecycle management and side-channel countermeasures.
• Solid understanding of PKI, certificate management and secure device provisioning, and a good grasp of the emerging post-quantum standards.
• Proven ability to connect high-level system requirements to low-level hardware and software implementation, and to explain trade-offs clearly to engineers, product and business teams alike.
• Master's degree in engineering or a related field.
• Fluent in both French and English, as you will work with French engineering teams and international customers.
• Bonus: experience with security certification processes (Common Criteria, FIPS, or similar) is a strong plus.

Responsibilities

• Defining the end-to-end architecture of secure hardware products, from the chip and its firmware up to the applications and the cloud platform that manages devices in the field
• Turning customer requests and market needs into clear technical specifications that silicon, firmware and software teams can actually build from, without losing the security intent along the way
• Setting the product requirements around performance, security hardening and integration constraints, and defending them when deadlines or customer pressure push the other way
• Keeping silicon design, firmware development and system integration moving in the same direction, so the pieces fit together at delivery instead of at the last minute
• Owning the long-term technical roadmap and making the hard calls between adopting new cryptography early and keeping the platform stable for customers who have already deployed it
• Working with sales and product leadership on RFPs and early-stage opportunities, judging what is feasible and defining the security scope before anything is promised
• Guiding the engineering team day to day by managing the backlog, setting priorities and unblocking technical decisions
