Volledige vacaturetekst

Every model we ship is only as good as its data. Blicker reads utility meters in production every day. Lapwing, our new LiDAR/3D AI product for the construction sector, is learning to understand underground assets. And our client systems in industry and logistics all depend on datasets that were selected, labelled, and monitored with care. Right now that care is spread across our AI engineers, in between their model work. We're looking for the person who makes it their job.

The role

You own the data side of every model we train. Today, our six AI engineers and consultants each carry a piece of it — selecting data, writing annotation instructions, checking label quality, watching for drift. It works, but it doesn't scale, and it isn't the sharpest use of their time. You take it over, run it better than we do now, and build it into something that scales with us.

A normal week looks like: curating the next training set (which of Blicker's new meter types are underrepresented? which Lapwing scans cover the edge cases?), reviewing annotations from our student pool and sharpening the instructions where labels disagree, checking whether production data has drifted since last month and assembling a retraining set if it has, discussing new features for our labelling and data management software with the software engineering team and running the annotation operation itself — scheduling students, onboarding new ones, and resolving the edge cases they surface. You sit in the middle of the AI team, and your work directly determines how good their models can be.

This is a new role. There is no predecessor's playbook — you define how data operations works at Clockworks, with the AI team beside you but the ownership genuinely yours.

What you'll work on

Own the dataset lifecycle for Blicker, Lapwing, and client projects: selection, versioning, quality metrics, dataset management
Monitor drift in production data and assemble retraining datasets when reality shifts, and build/automate the systems that monitor this
Write and sharpen annotation instructions, guard label quality, and troubleshoot the edge cases annotation surfaces
Run and grow our student annotation pool: recruiting from (tech) universities (Delft, Eindhoven, Nijmegen, etc.), onboarding, scheduling, quality feedback
Build the tooling and process that make all of this repeatable — you decide what good data ops looks like here

Collaboration

You sit in the middle of our AI and software engineering teams. You won't just be managing data; you’ll actively collaborate with the AI engineers to design model experiments based on your data insights, and work closely with software engineers to refine our internal data tools and infrastructure. Your perspective on the data will directly influence the development of our models and the systems that support them.

The challenge we'd love you to claim

Our annotation pool is more than labelling capacity — it's also where we find our future computer vision/AI engineers. We want it to become something with a reputation: a bigger pool, a proper communication channel, workplaces in our office for students who want to come in, students joining our Thursday drinks and demos, and a party once/twice a year — for them and for the team. None of this is a requirement of the role; the data work stands on its own. But if building that community sounds like your kind of challenge, it's yours to claim, and we'd love you to claim it.

Who we're looking for

Must-haves:

A beta BSc/MSc — computer science, mathematics, AI, physics, or similar
Structured and precise: you enjoy getting details right and keeping an operation running, week after week
Comfortable with Python and data tooling — or a demonstrated track record of picking up tools fast
A feel for what makes training data good — class balance, edge cases, label consistency, drift — or the drive to master it quickly
Comfortable instructing people and giving direct, kind feedback: you'll be running a student team

Nice-to-haves:

Hands-on annotation experience or familiarity with annotation tooling — time in our own pool counts double
Familiarity with computer vision models and their failure modes
Organizer energy: communities, events, getting people to actually show up
Dutch (the student pool is largely Dutch-speaking)

Annotation operations is detail work, and quality problems have a talent for surfacing at the worst possible moment. Students cancel, mislabel, and graduate, the operation has to keep running anyway. Drift monitoring means being the person who spots bad news early and says it out loud. And because the role is new, you'll sometimes be building the road while driving on it. If that energizes you more than it scares you, keep reading.

Salary & what we offer

€3,600 gross per month (within Band B — Junior of our published salary framework; 2026 band €3,475–€5,977; excluding 8% holiday allowance)
Annual performance-based raise (typically 2–8%) through a transparent review
Annual performance-based bonus, with individual and shared company goals
A solid pension plan
28 vacation days (40h week) and 8% holiday allowance
NS Business Card or €0.25/km — our office is directly at Rotterdam Central Station
Flexible hours around a 10:00–16:00 core; office-first with real room to work from home (most of us work one or two days a week from home) and one fully remote week per year
Team lunch included; training handled generously case by case, on working time
Real responsibility from day one: this entire domain is yours

About Clockworks

Clockworks builds AI that simply works. From Het Groothandelsgebouw at Rotterdam Central Station, we have been building AI solutions that run in production since 2017 — no demos that gather dust. From computer vision and classic machine learning to LLMs and agentic AI: we handle the complex machinery under the hood so users get something simple and reliable. We do this in bespoke projects for industry and logistics, and in our own products such as Blicker. We are a team of around fifteen: small enough that your work counts, big enough to build serious systems.

How we hire

An intro call (30 minutes — mutual fit, role scope, salary confirmed in the open). Then an in-depth conversation with the AI team plus a small, realistic case based on our actual data work — we discuss it together, we don't harvest free work. Then coffee with the founders and a walk through the terms. Offers are written, with your band position and growth path per our published salary framework spelled out. We respond to every application.

Sound like you?

Send your CV and a short note on why this role fits (a few sentences is enough — no formal cover letter needed) to [email protected]. Questions? Contact Victor Westerwoudt directly.

Note: unsolicited services or offers from recruitment agencies will not be responded to.
