Job description

You build domain-specific AI software and the digital twins for our clients, from the first prototype right through to production.

At Bonsai you won't build demos or proofs of concept that gather dust in a drawer. You build software that runs the operations of the country's largest organisations: what you make turns up on the road, in the news and on supermarket shelves.

You work full-stack on the edge of AI: the data pipelines and agents, plus the interfaces that planners, engineers and drivers rely on every day. You stay close to the client and own what you ship, from the first prototype right through to production.

The role

What you'll do

• Build AI agents and software that actually run in live operations.
• Design integrations with ERP, TMS and customs systems.
• Co-architect the digital twins we build for clients.
• Safeguard quality, evaluation and reliability in production.

Your profile

What you bring

• Strong fundamentals in Python and/or TypeScript.
• You've shipped production software, not just notebooks and demos.
• You think about what solves a problem on the shop floor, and you leave the hype out of it.
• You enjoy working close to the client.

A plus, not a requirement

• Experience with LLM pipelines, agent frameworks or RAG in production.
• Cloud (AWS or GCP) and containers.
• Domain knowledge in logistics, ports or industry.
• A feel for data quality and evaluating AI output.

Stack & tools

Your first months

Week 1-2

Get up to speed on a live case and ship your first pull request to production.

Month 1

Your first AI software is running live at a client.

Month 3

You co-architect a digital twin and steer the technical choices.

What we offer

Working at Bonsai

Production, not POCs

Ownership from day one

Small team, real responsibility. Spot a gap and you go after it, and your work ends up live at the client.

The best AI tools

You work with Claude Code, ChatGPT, Figma and Copilot. We automate our own work just as hard as the client's.

Rotterdam, hybrid
