Maarssen (Utrecht) | 32–40 hours | Hybrid | Up to approx. €7,000 gross per month
For a fast-growing Dutch software company in transport and logistics, we’re looking for a Senior / Principal Software Engineer who still wants to stay genuinely hands-on.
This is not the classic path where becoming senior means spending most of your time in meetings, people management and coordination.
In this role, roughly 80% of your time is spent building software. The other 20% is focused on architecture, technical decision-making, problem solving, mentoring and challenging the team to build better software.
You’ll work on a large, business-critical SaaS platform used by hundreds of logistics companies to manage processes such as order management, transport planning, Track & Trace, driver workflows, financial integrations and reporting.
The platform is complex. And that’s exactly the point.
A large part of the codebase is written in Delphi, but don’t let that define the role.
The company actively invests in the product, continuously refactors the codebase and applies modern software engineering principles to make the platform faster, more scalable and future-proof.
That means working with topics such as:
The team has even built its own solutions and patterns where Delphi did not provide what was needed out of the box.
So yes, strong Delphi experience is interesting.
But we are deliberately looking broader.
If you come from C#, .NET, Java, C++ or another serious engineering environment and you think in concepts rather than languages, we’d still like to talk.
You’ll work end-to-end on a complex software product that sits at the heart of logistics operations.
That means you won’t spend years maintaining one API or one isolated component.
You’ll be involved in:
You’re expected to have an opinion.
Not because being opinionated is a goal in itself, but because seniority here means understanding the trade-offs, explaining them clearly and taking responsibility for the outcome.
We’re looking for someone with real engineering depth.
Ideally, you have:
Dutch is a plus, but not required. More importantly, we’re looking for someone who sees software engineering as a craft, not just a job.
Someone who still wants to learn.
Someone who asks why.
Someone who doesn’t say:
“That’s not my component.”But instead:
“Why is this happening, and how do we solve it properly?”Job titles are not that important to us.
You may currently be called:
What matters is that you can independently analyse complex technical problems, influence technical direction and still enjoy building software yourself.
This is explicitly not a pure management position.
The internal development team consists of around ten engineers and works closely with Product, the CTO/architect, QA and external development teams.
The company is moving quickly from a traditional software environment towards a SaaS-first model and continues to invest heavily in both technology and product development.
AI is not treated as a future topic here.
The expectation is that strong engineers are already experimenting with it, improving their workflow and thinking critically about what it means for software development over the next few years.
The culture is direct, entrepreneurial and pragmatic.
People challenge each other.
You get freedom, but that freedom comes with ownership.
If you need every task to be fully defined before you start, this probably won’t be the right environment.
If you prefer:
“Give me the problem, the context and the desired outcome — I’ll figure out the rest.”
then it probably will.
Depending on experience and level, the salary goes up to approximately €7,000 gross per month for an exceptional senior/principal profile.
On top of that:
Because technical collaboration, knowledge sharing and whiteboard sessions matter, regular presence at the office in Maarssen is expected.
The software is business-critical and used 24/7, so an occasional on-call rotation is part of the role.
Because you won’t be hired to simply keep an old system alive.
You’ll join a company with a complex product, hundreds of customers, a strong growth ambition and a codebase they plan to keep investing in for years.
And because the team is relatively small, your technical opinion will genuinely matter.
If you’re a senior engineer who still sees software development as a craft and wants to stay technically sharp, we’d like to hear from you.
