Stormshield, the leading French publisher and European reference player in cybersecurity, is a subsidiary of Airbus Defence and Space Cyber Programmes and offers innovative, certified, European‑level‑qualified security products for protecting networks and data. To keep growing, we are looking for a Senior C/C++ Developer.

This person must master native development on Windows, be comfortable with continuous‑integration processes, and actively contribute to code quality and security.

What are the responsibilities of the Senior C/C++ Developer?

• Analyse, reproduce and fix incidents reported by support or customers, and manage technical debt;
• Design, implement and test new features in modern C++ (resource management, smart‑pointers, STL, constexpr, std::thread, etc.);
• Work hand‑in‑hand with Product Owners and Tech Leaders to create functional and technical specifications;
• Provide strong expertise to the support team (crash analysis, diagnostic scripts, “how‑to” documentation);
• Apply defensive‑programming principles (input validation, buffer limits, encryption, …) in both C and C++;
• Participate in pull‑requests, mentor junior developers and spread best practices.

And, as a bonus, depending on your interests:

• Optimise our CI pipeline (security‑test deployment, static analysis, build artefacts);
• Become an internal trainer, run Tech‑Talks, take part in innovation days…;
• Share your favourite domain (reverse engineering, driver development, cryptography, etc.).

What is the technical environment?

• Languages: C (C99/C11), C++ (C++ 17/20)
• Windows development: Visual Studio 2019‑2026, SDK/WDK, COM, kernel‑mode drivers
• Continuous integration: Jenkins, Git, automated pipelines (unit tests, static analysis)
• Analysis & debugging: WinDbg, Sysinternals Suite (Process Explorer, Process Monitor, ProcDump…)
• Methodologies: Scrum, LeSS, Kanban, TDD, code reviews, defensive programming
• Domain focus: endpoint protection, data encryption, access control, EDR

Which team?

You will join the R&D team for Endpoint & Data Security products, made up of roughly 30 people organised in Scrum/LeSS and Kanban (large‑scale agility).
