Job description

Frontend Engineer (f/m/d) at Manex AI in München, BY, DE. This Full time on site position offers great opportunities for career growth.

Who We Are

Manufacturing runs on fragmented data: machines, sensors and decade-old systems that don't talk to each other. Data sits in departmental silos, knowledge lives in people's heads, and AI can't unfold its potential in point solutions that don't deliver. At Manex AI, we build the missing layer. Our platform handles manufacturing data at scale, models the factory ontology and builds agentic applications that reason and act across it. We're a fast-growing team in Munich, backed by Lightspeed and BlueYard, with engineers from top companies and leading enterprise manufacturers as customers. We ship fast, work close to the shop floor, and we don't ship things we're not proud of.

The Role

What You'll Do

Platform: Build the interface for Kosmos, the platform that brings together enterprise data, operational context and AI

Applications

• Build interfaces for manufacturing applications that run on and are embedded into Kosmos
• Framework & DX: Ship the components, conventions, tooling and guidance that help AI agents, full-stack engineers and forward-deployed engineers build better UI faster
• Architecture: Make the calls that keep our frontend consistent, maintainable and ready to scale

You Should Apply

If you 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, we care more about evidence of cleverness, craft and learning speed than about years of experience, credentials or prior use of our exact stack.

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 stateExperience designing tools or interfaces for AI-assisted development

What We Offer

• 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 and a subsidized Deutschlandticket
• Regular offsites with the greatest team: think Austrian mountains, lakeside retreats or European cities
• Relocation support, including corporate housing offers
