Frontend Engineer

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 As Frontend Engineer, you'll work across our entire frontend ecosystem and own frontend systems end-to-end. You'll use AI to ship a high volume of polished work while making thoughtful architectural decisions that keep our frontend coherent and easy to extend. You'll work directly with founders, engineers and customers, and see your work used on real factory floors. What You'll Do Platform: Build the interface for Kosmos, the platform that brings together enterprise data, operational context and AIApplications: Build interfaces for manufacturing applications that run on and are embedded into KosmosFramework & DX: Ship the components, conventions, tooling and guidance that help AI agents, full-stack engineers and forward-deployed engineers build better UI fasterArchitecture: 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 outputCare about architecture and know when to create a reusable abstraction, and when not toHave strong visual judgment and notice when an interface feels confusing, inconsistent or unfinishedEnjoy turning recurring UI problems into primitives, patterns, documentation and tooling for other buildersCare about frontend fundamentals such as usability, accessibility, performance and maintainabilityLearn 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.jsDesign systems, component libraries or StorybookVisual regression, accessibility and browser testingSDKs, developer platforms, embedded applications or microfrontendsComplex interfaces involving data grids, graphs, editors, workflows or real-time stateExperience designing tools or interfaces for AI-assisted development Our current stack includes Next.js 16.3, React 19, TypeScript, Tailwind CSS, Radix-based components, TanStack libraries, Storybook, Vitest and Playwright. Familiarity helps, but none of these tools is a prerequisite.
