AI Engineer

We at Lumion make beautiful, high-performance desktop software for architectural visualization. Think: gorgeous buildings, smooth lighting, slick renders — the works. Now, we’re on a mission to develop some AI enhancements on top.

We're not trying to build the next ChatGPT or reinvent neural networks. We just want to make our app smarter — with clever, useful, jaw-droppingly cool features — using the powerful AI models already out there in the wild. That’s where you come in.

What You’ll Actually Do

You're not a lab researcher. You're a feature whisperer who knows how to make AI do things. You'll use open-source models (diffusion, GANs, vision transformers, etc.), evaluate a few APIs, glue things together, and help our users get magical results with minimal clicks.

Here are some things we’re dreaming about:

• Turn a crappy photo into a stunning material.
• Auto-generate textures or assets with zero human suffering.
• Help users get better renders faster with upscaling, denoising, smart defaults.
• Integrate AI into creative workflows without making it feel like AI is taking over the world (yet).

We’re Looking for Someone Who:

• Has experience working with AI/ML in real-world, non-academic settings
• Knows how to wrangle pre-trained models (PyTorch, ONNX, Hugging Face, etc.)
• Loves building things, not just running experiments
• Can work in Python, and ideally isn’t afraid of C++ (or people who use it)
• Understands that “AI-enhanced” should never mean “mysteriously broken”
• Bonus: You’ve played with 3D software, graphics pipelines, or materials/textures

Why You Might Like It Here

• No infra-heavy LLM nonsense — just real features for real users
• Small team, high trust, low politics
• Ownership from day one: prototype, iterate, ship
• We’re allergic to buzzwords, but not allergic to shipping cool stuff
• An attractive salary and bonus structure.
• Full-time contract.
• 30 vacation days per year.
• 20 workation days to work remotely from anywhere.
• Local Office Benefits: Free lunch and free office gym.
• The opportunity to work in an enthusiastic, international team, in a creative environment, focused on people, growth, and collaboration.
• Ideally, we'd love this person to be based in the Netherlands but we are open to remote as well.
