Front-end Engineer

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.

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
