Germany - EU Remote (CET preferred) · German & English · Full-timeCompetitive salary · Early equitywww.3ive.aiAbout UsA software engineer today works alongside Claude Code or Cursor. A mechanical engineer designing the next car component still clicks through CAD trees, up to 7 different softwares and searches Excel sheets, Windows folders and asks whoever has been around longest.AI is about to change that fundamentally – and nobody has figured out yet what the interface for it looks like.That is why we are building the AI co-engineer for physical products: agents that work natively in 3D, sit on top of CATIA, NX, SOLIDWORKS and Creo, and learn from real-world engineering decisions.We are already in production with major European manufacturers.🔍 Who we're looking forWe are a small, AI-native team and we need a senior designer who defines how engineers and AI agents work together in 3D. You own product design end-to-end and take on a real share of product management (~30%) together with the founders.You have designed complex B2B / SaaS products – dense data, multi-step workflows, expert users who don't forgive frictionYou have shipped AI and agent experiences – not just chat, but human-in-the-loop review, uncertainty, and making an agent's reasoning traceableYou prototype in code – and put working prototypes in front of users, not just Figma framesYou think like a product manager – you run user interviews, write crisp specs, prioritise ruthlessly and work directly with engineersYou combine taste with pragmatism – you know when to polish and when to shipYou are fluent in German and English – our users are engineers at German manufacturers and you will talk to them directlyExperience with 3D, CAD, PLM or other engineering software – ideally in a startup – is a strong plus.🏗️ What you'll work onYou will shape the future of agentic 3D design and engineering. There is no pattern library for this category yet – you will write it. What that looks like right now:Designing how an engineer briefs, steers and reviews an AI agent that generates and modifies 3D designs – from a customer request to a validated design variantMaking agent work inspectable in 3D – viewers, cuts, measurements, 2D drawings, and a clear view of what the agent changed and whyTurning a fast-grown product into a coherent design system together with our frontend engineersRunning research loops with engineers at automotive and industrial customers and turning them into roadmap, specs and shipped featuresWe work with Figma, Flowbite, Linear and a modern Python and TypeScript stack – and we prototype with AI every day.✨ Why joinDefine the interaction model for a category that does not exist yetReal enterprise customers, real revenue, real problems - not a solution looking for a marketDirect line to the founders – product vision and design decisions happen in the same conversationRemote across Europe with in-person client workshops and team offsitesCompetitive salary and meaningful early equity📩 How to applyVia Ashby with:Your CVYour portfolio – at least two case studies of complex B2B or AI products, showing your process, not just final screensA link to something you prototyped in codeA 2-min intro video (any format you like)A short answer to: "What is the most complex workflow you have simplified – what made it hard, and what did you decide to leave out?"No recruiters, no portals.Find more English Speaking Jobs in Germany on Arbeitnow
