Role · Developer
What does a developer do in a data team?
A developer builds, maintains and improves software that supports, automates and connects processes. Where a data engineer keeps the data flowing, the developer builds what sits around it: the application, the integration, the internal tool that does the work every day.
What do you do in this role?
Our developers make sure ideas actually work in practice. They build, maintain and improve software that supports, automates and connects processes.
- Developing applications and internal tools
- Automating processes and workflows
- Integrating systems and data sources
What companies look for in a developer in a data team
- Someone who can talk to an analyst without disappearing into technicalities, and to an engineer without disappearing into wishful thinking.
- Integrations that keep working when the other side changes. Integration is most of this work.
- Internal tools somebody actually uses; not the prettiest screen but the one that fits how people work.
- Enough sense of data to know when a field must not simply be empty.
What matters
- One language thoroughly, plus SQL. Which language matters less than how well.
- APIs: building them and, just as importantly, keeping other people's running.
- Git, tests and a deployment that does not come out of one person's hands.
- Some infrastructure: containers, a pipeline, being able to read logs.
- Judging when an existing package beats building it yourself.
How the role is changing
AI writes a growing share of the code, and that shifts the work towards judging rather than typing: is this right, does it fit what is there, what will break. At the same time integration work grows, because organisations tie together more separate services than ever. Those who grow here move towards platform work, architecture, or towards the client's own field.
How you stand out among the other hundred
By showing something used by other people that you had to change after it went live. Anyone can show code they wrote; maintaining what is there, with users who have opinions, is the real work. Tell us which assumption turned out to be wrong and what you changed.
What every role has in common
Companies increasingly look for someone who is broadly deployable. That does not mean you have to be able to do everything: it means you look into the disciplines around yours.
As a BI specialist you do not have to be an AI specialist. But if you demonstrably use AI in your work and keep learning about it, you become added value rather than replaceable. The same goes for communicating across departments: anyone who recognises the problems, pitfalls and opportunities of sales or finance delivers work that actually lands there.
What you can earn
Our own rates are based on a gross full-time monthly salary of € 3.000 to € 3.200. That is the floor we work from for a starting professional working full time.
A market indication per role is deliberately absent. The same job title varies widely between companies (a senior BI specialist earns noticeably less at one employer than at another) and the region weighs heavily: Amsterdam sits above Eindhoven, Eindhoven above Rotterdam, and Rotterdam above Drenthe. Quoting a number without checking it would mislead you in a conversation about your own income.
Just ask us. We see what the market pays and we will tell you what we know, including when we do not know.
