Founding Product Designer

3Ive; Deutschland; Remote; EUR 90,000 - 130,000; Full time

Job summary

3ive.ai is hiring a senior designer to shape the future of agentic 3D design and engineering. You will own product design end-to-end and share ~30% product management duties with the founders.

You will work with a small AI-native team on B2B SaaS products, prototypes in code, and direct collaboration with engineers, while engaging with German manufacturers remotely across Europe.

Qualifications

• You have designed complex B2B / SaaS products with dense data and multi-step workflows.
• You have shipped AI and agent experiences, including human-in-the-loop review and traceable reasoning.
• You prototype in code and present working prototypes to users, not just mockups.
• You think like a product manager: run user interviews, write crisp specs, prioritise with engineers.
• You combine taste with pragmatism: know when to polish and when to ship.
• You are fluent in German and English and can communicate with engineers in Germany.

Responsibilities

• Design how engineers brief, steer and review an AI agent that generates 3D designs from requests to validated variants.
• Make agent work inspectable in 3D: viewers, cuts, measurements, drawings, and change reasoning.
• Turn a fast-growing product into a coherent design system with frontend engineers.
• Run research loops with automotive/industrial customers to build roadmap, specs and features.

About Us

A 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 for

We 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 friction

• You have shipped AI and agent experiences – not just chat, but human-in-the-loop review, uncertainty, and making an agent's reasoning traceable

• You prototype in code – and put working prototypes in front of users, not just Figma frames

• You think like a product manager – you run user interviews, write crisp specs, prioritise ruthlessly and work directly with engineers

• You combine taste with pragmatism – you know when to polish and when to ship

• You are fluent in German and English – our users are engineers at German manufacturers and you will talk to them directly

Experience with 3D, CAD, PLM or other engineering software – ideally in a startup – is a strong plus.

What you'll work on

You 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 variant

• Making agent work inspectable in 3D – viewers, cuts, measurements, 2D drawings, and a clear view of what the agent changed and why

• Turning a fast-grown product into a coherent design system together with our frontend engineers

• Running research loops with engineers at automotive and industrial customers and turning them into roadmap, specs and shipped features

We work with Figma, Flowbite, Linear and a modern Python and TypeScript stack – and we prototype with AI every day.

Why join

• Define the interaction model for a category that does not exist yet

• Real enterprise customers, real revenue, real problems - not a solution looking for a market

• Direct line to the founders – product vision and design decisions happen in the same conversation

• Remote across Europe with in-person client workshops and team offsites

• Competitive salary and meaningful early equity
