Who should you write to at Comand Ai?

Your free dossier identifies the people who'd interview you — their background, what they value, and how to reach out so you stand out before applying.

Comand AI's mission is to build next-generation C2 software with real users in real deployments. 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. 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 Ownership of a product surface used in real operational environments Direct collaboration with product design and engineering, with room to shape front-end standards as the team grows 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.
