What you will do

We have created a technique to find out whether a hatching egg holds a male or a female chick, so we can prevent the male chicks from hatching. This leads to a big animal welfare win, and a very interesting, yet complex process.

Our machine, Ella, is designed to carefully take a sample of fluid from the hatching egg, making sure not to hit the bird-to-be inside. These tiny drops are analyzed using a mass spectrometer to see whether the egg holds a male or female.

Ella is controlled by software that integrates all the various modules. As a PLC Software Engineer, you will work alongside 8 colleagues in the Data & Software team (part of the R&D department). Together with the team, you will work on improving the software in our high-tech Ella machine.

Your responsibilities include:

  • Collaborating with mechanical engineers on strategic projects to develop new modules for Ella
  • Programming new PLC software and deploying it
  • Maintaining various software modules to ensure smooth operation of Ella
  • Debugging complex problems

In general, you will evenly divide your work between working on new projects, preventative maintenance and ad hoc debugging of the modules.

Job requirements

Our introduction (not boring, we’re cool)

In 2011, the first In Ovo pipettes hit the lab. The goal was clear: to stop the unnecessary killing of day old male chicks.

The first samples were carefully taken by hand. It took some years to get there, but in 2016, it worked: a single drop of the egg’s fluid was enough to see whether it held a boy or a girl. One done, only 13 billion to go.

As you can imagine, we needed a machine.

The first steps into industrialisation were taken and a huge impact on animal welfare was lurking. In 2020, our first machine was up and running. We named her Ella. What a beauty.

Taking a huge leap to today’s In Ovo: we’re a team of over 60 people, 3 Ellas and millions of saved chicks. We are engineers, operators, scientists, office people and everything in between. The go-getters of the poultry industry who roll up their sleeves to improve animal welfare. And Ella is just the beginning.

We believe that animals deserve a dignified place in a sustainable food industry. And we need way more people to fulfil our mission of improving the lives of 5 billions animals by 2030.

Are you with us?
