Who we are Comand AI is building a global technology leader focused on defense & security. The company was co-founded in 2023 by Loïc Mougeolle, Marie Inuzuka and Quentin Le Pape, drawing from their unique experience at defense industry leaders and world-class tech companies. The world of defense & security are being entirely renewed by AI and robotisation: new classes of threats, new levels of autonomy and speed demands radically new solutions to protect our societies. Comand AI is at the forefront of the rebuilding of these verticals to serve our countries resilience. Comand AI core product is a next generation command and control software platform, which allows militaries to operate at machine speed in a communication and GNSS denied context. A few facts to anchor you: • €45M raised from seed to Series A, Blossom Capital leading the series A and Saab as a strategic investor • Software platform combat proven and deployed in Ukraine • A lean team of operators with backgrounds from Palantir, OpenAI and world-class tech experience, alongside unique expertise from the defense sector • Live business with governments and defense industry leaders across Europe • Paris (HQ), London, Munich and Kyiv subsidiaries The Role We are fully indexed on the success of every user, the interfaces you ship support live operations. You'd join the product development team as a front-end specialist, working closely with product design and engineering. You take an operational problem, explore it, come back with proposals, and iterate. Delivering a clear, fast and dependable user experience is critical to the person using it. What this looks like in practice: • Own front-end delivery on Prevail, our operational planning platform, from interaction design through production • Build interfaces for real geospatial problems: interactive maps, multiple data layers, large datasets, and time-sensitive workflows well beyond a typical CRUD application • Work with product and design early, turning operational needs into clear flows and production-ready experiences • Raise the front-end quality bar across the team by reviewing and improving work from engineers with different specialities, including AI-assisted code • Make thoughtful trade-offs between speed and durability, especially when a high-stakes demo or deployment creates a short deadline • Help create reusable patterns that make the product more coherent as the team and surface area grow Who We're Looking For We filter hardest on mission drive, low ego, attention to detail, and resilience under pressure. We want someone who cares about front-end engineering as a craft and can still move quickly when the problem is ambiguous. Must-have: • Strong production experience with React and TypeScript, with front-end engineering as a core part of your craft • A track record of owning complex interfaces from problem definition through release and iteration • Strong product and design judgement: you notice weak hierarchy, inconsistent interactions, and confusing states before a specification points them out • Pragmatism and low ego: you can improve rough work from other engineers without turning every implementation choice into a philosophical debate • Comfort with ambiguity and changing priorities, while keeping the quality of what ships high • EU or UK citizenship (contractual requirement tied to our defence contracts) Nice to have: • Experience with mapping, cartographic, GIS, or other geospatial applications • Front-end performance work involving large or real-time datasets • Experience building offline-capable or resource-constrained web applications • Experience creating or scaling a design system • Prior work in defence, government, or dual-use technology What's In It For You • A top 0.1% European compensation package, including base salary and equity • Paris or London based The Process • Talent screening: 30 min, online. We cover your background, motivations, and what you want to own next. • Front-end interview: 60 min, online. We assess React and TypeScript fundamentals, product judgement, and how you reason through an unfamiliar interface problem. • Onsite in Paris: half day. You see the product, present a project you are proud of, and work through a front-end design and re-engineering exercise based on a realistic product problem. • Roundtable: hiring committee reviews the full set of evidence and makes the final decision.
