Senior Software Engineer

Company

We're the AI design platform powering some of the world's biggest fashion brands and retailers — official LVMH partner, real enterprise contracts, real production load. Our product covers Brand DNA analysis, AI-driven design, trend intelligence, tech packs, 3D garment visualization, and AI photoshoots.

We're a small, fast team. AI writes a lot of our code now — what we hire for is the engineer who orchestrates it: designs the system, picks the right abstraction, judges the output, and ships quality. Typing speed isn't the moat anymore. Taste and judgment are.

What you'll do

• Build backend (occasionally frontend) features end-to-end and own them in production
• Design and ship LLM, vision, and 3D pipelines — RAG, agents, embeddings, fine-tuning, evaluation
• Work across foundation models (Flux, Qwen, Hunyuan3D, Gemini, Claude) and orchestrate them into production-grade workflows
• Prototype Monday, deploy Friday, iterate next week — without sacrificing what makes the codebase last

Who you are

• Solid traditional engineering fundamentals — clean code, good system design, production-grade habits
• An AI power user in your daily workflow (Claude Code, Cursor, ChatGPT, etc.) — you orchestrate, not type line by line
• Analytically sharp: ask "why" before writing code, spot the right abstraction, push back on bad ideas
• Comfortable owning ambiguity end-to-end
• 4+ years building backend systems in Python (or equivalent)

Stack: Python · FastAPI · PostgreSQL + pgvector · GCP · Docker · React (occasionally)

Nice to have: generative AI in production · computer vision · 3D / Blender · vector DBs and retrieval · fashion-tech background

Why Refabric

• Real AI work: design, vision, 3D — not chatbots
• Small team, big leverage. You ship things that move the business.
• Apply with your CV + a few lines on the most interesting AI-powered system you've built or shipped.
