About the job

Mistral AI is seeking a talented and experienced Software Engineer with a strong focus on security to join their Engineering & Infrastructure team. This full-time, hybrid role is based in locations such as Paris, London, Berlin, Madrid, and more, with a preference for candidates based in France due to visa sponsorship availability. As part of a dynamic, international AI company, you will work closely with research, product, and program management teams to deploy and optimize frontier AI models across cloud and on-premises systems. Key responsibilities include launching new features, developing APIs and model interfaces, improving deployment infrastructure, enhancing system performance, and implementing observability and safety measures. You will also take a leadership role in promoting secure coding practices, reviewing system architecture, managing vulnerabilities, and integrating robust security standards. Ideal candidates have a Master’s in Engineering or Computer Science, strong backend or fullstack development experience (particularly in Python), familiarity with security protocols, and the ability to work autonomously in a fast-paced, innovative environment. Mistral AI offers competitive salary, equity, health and sport benefits, pension plans, meal vouchers, and relocation support. New hires are expected to onboard in Paris for the first month, with monthly in-office presence thereafter, and visa sponsorship is offered for candidates based in France.
