Job description

Senior AI Research Engineer

๐Ÿ“ Netherlands - Hybrid ๐Ÿ’ถ Up to โ‚ฌ110k + benefits & equity

๐Ÿ› ๏ธ AI: LLMs, RAG, agentic systems, evals & guardrails

Some markets are slow because they're genuinely hard. This one is slow because nobody's bothered to fix it.

An Amsterdam startup is changing that. They're rebuilding how regulated firms onboard new clients, today a weeks-long mess of emails, manual checks and chased paperwork. Their platform turns it into something clean that takes days, and quietly keeps bad actors out of the financial system while it's at it.

This is a young, international team and they are looking for an AI engineer who's going to accelerate their growth even further! You'd report straight to the founder and own real surface area from day one.

Most of what you build is greenfield. You're designing systems, and building something secure and exciting. Whatever you ship is in front of paying customers within days, and the feedback lands in real time!!

This isn't a slide in a pitch deck. The product is live, the runway runs years deep, and the market is old, niche, and barely contested.

๐Ÿ’ถ Salary up to โ‚ฌ110k + benefits

๐Ÿ“ Amsterdam HQ

๐Ÿค A genuine founding-team seat - flat structure, direct line to the CTO

โšก Your work ships to real users in days, not quarters

๐Ÿง  An AI-native engineering culture - Claude Code, Codex and friends are part of the daily toolkit, not a side experiment

๐Ÿชด Meaningful equity - real skin in the game

๐Ÿ— Real ownership of backend architecture, security and core business logic

What you'll be doing

๐Ÿ” Build the reasoning layer that goes beyond retrieval - linked data, knowledge graphs, structured formal knowledge

๐Ÿค– Design complex multi-agent systems that reason across regulation and stay correct end to end

๐Ÿ‘๏ธ Bring language and vision together over data-heavy documents - plans, drawings, blueprints

๐Ÿ›ก๏ธ Own the evaluation and guardrails that keep every cited answer trustworthy

๐Ÿงญ Set the technical direction as the first dedicated AI hire, working directly with the founders

You'll love this if...

โœ… You've built something most AI engineers haven't - linked data and AI, knowledge graphs, complex multi-agent, or multimodal in a data-heavy domain

โœ… You understand models from the inside - fine-tuning or post-training, not just calling an API

โœ… You're drawn to formal, high-stakes domains - legal, regulatory, medical, construction

โœ… You want founding-level ownership and equity, not a seat in the machine

โœ… You can go deep on the hard problem and still ship pragmatically

Apply today!

Because great teams are Built Different.
