Engineering Team Lead, DevEx

At Mistral AI, we believe in the power of AI to simplify tasks, save time and enhance learning and creativity. Our technology is designed to integrate seamlessly into daily working life, and we democratise AI through high-performance, optimised, open‑source models and solutions that meet enterprise needs across on‑premises and cloud environments. Our AI platform powers products such as Le Chat, the AI assistant for life and work, and the Mistral Vibe platform.

Role Summary

As a team lead, you will own both execution and delivery while remaining hands‑on. Your team will typically be about five people and you will split your time dynamically between individual contribution and leadership, with the balance shifting as the team grows. You will collaborate closely with engineering teams to ship improvements that accelerate development velocity, enhance code quality, and streamline workflows for AI Studio, Le Chat, and Mistral Vibe. You will be responsible for creating a strong team culture, setting clear processes, raising the developer experience bar, and ensuring consistent, high‑quality delivery of developer tooling and infrastructure.

What You Will Do

• Empower Your Team: Act as the clear point of contact for your team and its projects, remove obstacles, unblock execution, and create an environment where engineers can focus on building impactful developer tools and platforms.
• Lead Delivery and Accountability: Own the delivery of your team’s roadmap for developer experience improvements, including projects such as enhancing CI/CD and build systems, optimising cloud registries (Docker, Azure, GCP), implementing static and dynamic code analysis tools, and automated vulnerability analysis. Ensure projects are shipped with the right level of quality, reliability, and performance.
• Bridge Engineering and Productivity: Partner closely with engineering teams to define the roadmap and priorities for developer experience. Scope initiatives, estimate engineering effort, and drive prioritisation decisions based on developer productivity impact and technical necessity. Keep the whole team involved and engaged in the product direction.
• Hands‑on Technical Leadership: Stay deeply involved in architecture design, system design, coding, peer reviews, and technical decision‑making for developer tooling. Lead by example and remain connected to the day‑to‑day challenges of the team.
• Process and Clarity: Define and evolve team processes, best practices, and execution rituals for developer workflows. Ensure they remain relevant as the team and product scale.
• Raise the bar: Challenge engineers to step up, take ownership, and grow beyond their comfort zone. Increase the team’s bus factor through knowledge sharing, documentation, and rotation of responsibilities. Champion a culture of continuous improvement in developer productivity.
