Your job in a nutshell

Solve complex last-mile puzzles with machine learning and optimization. Build smart solutions that improve delivery planning, use capacity more efficiently, and directly impact how we serve our customers every day.
What are we doing it for?

We make groceries easy, affordable, and reliable. By improving our last-mile planning, you help us deliver faster, reduce costs, and create a better experience for millions of customers.
Your new team

Join a small, driven Tech team in Veghel. Work with backend, full stack, and ML engineers who love solving complex problems and delivering real impact in a fast-moving environment.
Who do you work with?

Collaborate closely with engineers, product teams, and supply chain experts. Together, you turn complex logistics challenges into smart, scalable solutions that improve our delivery performance.

At Jumbo, we do everything we can to offer delicious, affordable, and responsible food for everyone. As a Machine Learning Engineer, you contribute to this every day by building smart optimization models that improve our last-mile planning and help us make better use of drivers, time, and delivery capacity.

Your role requires finding a balance between an efficient delivery operation and meeting our customers' needs. By doing so, you will be able to provide the best possible delivery experience to our customers while ensuring that the deliveries remain sustainable. For example, by providing better insights into when we will arrive to the customer, smaller time windows, reducing delivery costs, allowing for a later cut-off, and providing the driver with more time to deliver the groceries.

Your key responsibilities:

Optimize delivery routes to improve efficiency, costs, and customer satisfaction
Develop machine learning models to predict capacity and improve planning decisions
Allocate orders to the most efficient fulfillment and delivery locations
Improve how we use drivers, time, and space in delivery vans
Build and maintain scalable backend services for planning and optimization
Solve complex optimization problems with many dynamic parameters and constraints
Collaborate with engineers and supply chain experts to translate business needs into solutions
Continuously improve last-mile performance, balancing operational efficiency and customer experience
Coach and support other team members, helping them grow in their technical skills and measure and optimize their impact

Together, we are Jumbo: This is where you'll work

At Jumbo, no two days are the same. We move fast and keep improving, for our customers and for each other. You’re encouraged to spot opportunities, take ownership, and make an impact. You’ll work in an informal, energetic environment with room for your ideas, humor, and fun. Together, with a strong dose of Jumbo DNA, we collaborate to win our customers’ hearts every day.

Together, we tackle complex puzzles every day. With many parameters in play, this is exactly the kind of challenge that keeps the work exciting. You’ll join a driven IT Development team in Veghel, part of our Tech department, with 2 backend engineers, a full stack engineer, and a junior machine learning engineer. A small, focused team where you learn fast, take ownership, and make real impact on our last-mile performance.

A strong foundation in mathematics and statistics, including probability, linear algebra, and optimization, comes naturally to you
Designing and validating models is something you do with a clear understanding of experimentation, hypothesis testing, and bias detection
End-to-end thinking defines your work, from modeling to deployment, evaluation, and continuous improvement
A broad range of techniques, from regression and tree-based models to optimization and neural networks, is part of your toolkit
Clean, production-ready Python code is your standard, with a focus on architecture, testing, maintainability, and applying design patterns and maintainable abstractions
Critical thinking is second nature: you challenge assumptions and make decisions based on data and scientific evidence
You enjoy sharing knowledge and supporting others, for example by coaching other team members

A gross salary between €5.900 - €7.600 per month (based on 40 hours).
An annual bonus of max 7,5% of your annual salary, based on organizational goals.
30 days of paid holiday (with the opportunity to buy or sell days of paid holiday) and 8% holiday allowance. You build up a pension through participation in the Pension Fund for the Food Industry.
An allowance for your travel expenses (€ 0.21 cents per kilometer with a maximum of 35 kilometers one way). We like to work together in the office, but you can also work partly from home.
Room for entrepreneurship, growth and development. Not only in your job but also through our Jumbo Academy, online training through GoodHabitz and with a training budget.
Daily fresh lunch in our Foodcafé, good coffee and fresh fruit. You can sport daily at our own Jumbo Gym for a small fee.
Colleague discounts such as 10% off your groceries (up to €325 per year), participation in our collective health insurance or discounts through Benefits at Work.
