Frontend Engineer (f/m/d)

The role

You will work across the entire frontend ecosystem and own frontend systems end-to-end. You will build the interface for Kosmos, manufacturing application interfaces, and tooling for other engineers.

What you will do

• Build the interface for Kosmos, the platform that brings together enterprise data, operational context and AI
• Build interfaces for manufacturing applications that run on and are embedded into Kosmos
• Ship the components, conventions, tooling and guidance that help AI agents, full-stack engineers and forward-deployed engineers build better UI faster
• Make the calls that keep our frontend consistent, maintainable and ready to scale

Required qualifications

• Use AI as a serious engineering tool and can turn it into a high volume of reliable output
• Care about architecture and know when to create a reusable abstraction, and when not to
• Have strong visual judgment and notice when an interface feels confusing, inconsistent or unfinished
• Enjoy turning recurring UI problems into primitives, patterns, documentation and tooling for other builders
• Care about frontend fundamentals such as usability, accessibility, performance and maintainability
• Learn unfamiliar technologies quickly and form your own judgment about technical tradeoffs

Nice to have

• TypeScript, React or Next.js
• Design systems, component libraries or Storybook
• Visual regression, accessibility and browser testing
• SDKs, developer platforms, embedded applications or microfrontends
• Complex interfaces involving data grids, graphs, editors, workflows or real-time state
• Experience designing tools or interfaces for AI-assisted development

Benefits

• A cooperative team where you own your work, but never solve hard problems alone
• High trust and ownership from day one
• Competitive salary and equity
• Corporate Wellpass membership
• Subsidized Deutschlandticket
• Regular offsites with the greatest team: think Austrian mountains, lakeside retreats or European cities
• Relocation support, including corporate housing offers
