About the Position

Data Extraction Specialist – AI

Location: Amsterdam, NL

Employment Type: Full-time

Salary: 38,000 - 58,000 € per year

About the Role

Do you want to teach a bank’s document engine to read?

Every mortgage application comes with a stack of documents: payslips, employer statements, valuation reports, bank statements, and IDs. Our extraction engine automatically turns these documents into structured data that can be used throughout the lending process.

Making that engine smarter is one of Ohpen’s key objectives for 2026, as we move from classical extraction rules towards AI/LLM-based extraction.

As a Data Extraction Specialist – AI, you’ll help drive that transition end-to-end. You’ll configure and optimize the engine, build the LLM-based extraction that replaces existing rules, benchmark the results to prove extraction rate.

Responsibilities

Improve extraction rates. Configure and tune DTA2 across different document types and fields, prioritizing those that matter most to our clients.
Roll out AI/LLM-based extraction. Design, build, evaluate, and deploy LLM-based extraction within the engine. This includes everything from prompt design and model selection to guardrails, evaluation sets, and production rollout.
Prove that it works. Build and maintain the benchmarking loop that shows where extraction has improved, where it has regressed, and why. No improvement ships without evidence.
Improve the engine itself. Identify and implement engineering improvements across DocStreet, DTA2, and Orbis.
Work closely with the people who use it. Collaborate with internal stakeholders across Product, Engineering, and Lending Operations, as well as directly with our clients.

Requirements

Analytically strong. You pick up new domains quickly and are comfortable being the person who figures out how things actually work.
Technical engineering background, with a degree in Computer Science, Software Engineering, Data Engineering, or a comparable field, and 1–5 years of hands-on experience.
AI-native. LLMs are a normal part of how you work. You know how to design and iterate on prompts and how to build benchmarks that show whether a change actually helped.
Proactive self-starter. In a small team, there is no one to wait for. You spot what needs doing, propose it, and take ownership of getting it done.
Strong communicator. You can explain technical trade-offs to clients, respectfully challenge colleagues when needed, and keep stakeholders informed without being asked.

Nice to Have

Experience with Java and AWS, as our engine runs on them.
Dutch language skills, as most of the documents we extract are in Dutch.
Familiarity with the Dutch mortgage market, ideally through previous experience working with Dutch mortgage products, processes, or systems.

We Offer

Ownership of a strategic 2026 objective from day one, in a team small enough that your work is visible to both clients and leadership.
The opportunity to move a production system used by regulated lenders from rule-based to AI-based extraction.
A role at the intersection of engineering, AI, and the Dutch mortgage domain.
Hybrid working from our office in the heart of Amsterdam.
Competitive compensation and benefits.
