Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Front-end Engineer - **Company:** Comand AI - **Location:** Paris, France - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Big Data, GIS Applications, Interaction Design, TypeScript, Web Applications, Web Performance Optimization, ReactJS, Data Layers, Front End Software Development, Crud - **Published:** September 7, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=90d3be9e93d4438d ## About the Role 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 ## Description 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, * 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.
