About the role

Delta Freight Cloud is hiring a Python engineer in Utrecht. This is a product engineering role in Python rather than a notebook role: services, scheduled work and the libraries around them, all of it tested and deployed like any other production code. If you have wanted Python work with real engineering discipline attached, this is that.

Dutch offers are quoted as an annual gross figure with the 8% holiday allowance normally paid on top, and the 30% ruling may apply if you are relocating.

What the work actually looks like

You will build and maintain services and pipelines, tighten the interfaces between them, and spend a fair share of your time on correctness — typed boundaries, tests that fail for the right reason, and data validation at the edges. There is regular pairing with the people who own the domain logic. The team works a hybrid week out of Utrecht, usually three days together and the rest wherever you work best.

What we look for

This is a mid-level role. You should already be able to take a loosely specified problem, break it down and ship it without close supervision. We are looking for command of the standard library, comfort with type hints and a real testing habit. Experience with FastAPI, Django or a serious data stack is welcome; the ability to reason about a slow query or a memory profile is what we will actually probe.

Working at Delta Freight Cloud

A four-day week is a normal request here rather than an unusual one, and genuine part-time contracts are available for this role. The range shown is the annual gross salary band for this role.

Responsibilities

Build and maintain Python services and scheduled jobs in production
Validate data at the boundaries so bad input fails loudly and early
Write tests that pin down behaviour rather than restating the implementation
Profile and fix performance problems with evidence rather than instinct
Keep dependencies and runtime versions current and boring

Requirements

Several years of Python in production, not only in notebooks
Comfortable with type hints, packaging and virtual environments
Experience with FastAPI, Django, Flask or an equivalent framework
SQL beyond the basics, including reading an execution plan
Familiar with containerised deployment and CI

Benefits

Delta Freight Cloud

Rotterdam51-200 peopleLogistics Software

Delta Freight Cloud plans container movements between the Port of Rotterdam and inland terminals across the Rhine corridor. Our software decides which barge, which train and which truck, and it is measured on empty kilometres removed rather than on features shipped.

The data is messy in ways only physical logistics can be: a vessel arrives eleven hours late, a terminal closes a gate, a customs message never lands. Handling that gracefully is most of the product.

We are based near Rotterdam Centraal with a small team in Utrecht. A four-day week is a normal request here rather than an unusual one.
