Internship

Seville

Open

Electronics or Systems Engineering internship

Write code that runs on a vehicle's electronics and reaches the street.

About Mothium

Mothium builds professional electric vehicles for urban logistics and the agents that run them. Synapse ships with every vehicle and today it runs maintenance, aftersales, routing and cost across real customer fleets. It is not a demo. It is operating.

What you'll do

Our vehicles carry a control unit, communication buses, sensors and an HMI, and above them Synapse, which runs maintenance, routing and cost for customer fleets. You will work where those two meet: writing and testing code on the actual electronics, capturing telemetry and helping to work out what it is telling us.

The difference from a coursework project is what happens when it is wrong. Code that behaves perfectly on a bench can fail on a route because of vibration, damp or a connector. You will watch that happen, with a senior engineer next to you, and you will learn to debug something you cannot pause.

Responsibilities

  • Write and test code on the vehicle's electronics, on real hardware.
  • Help capture, clean and analyse telemetry from vehicles in operation.
  • Support the agent team on integration between the vehicle and Synapse.
  • Document what you build and what failed, so the next person does not repeat it.

What we're looking for

  • Studying electronics, telecommunications or computer science, with a university internship agreement in place.
  • Fluent programming in at least one language, and an appetite for touching hardware.
  • Comfortable with a command line, version control and documentation in English.
  • Based in Seville or willing to relocate.

Counts in your favour

  • Personal projects with microcontrollers, sensors or robotics.
  • Any exposure to C, C++ or Python on embedded hardware.

You will fit here if

  • You want your code moving something physical rather than sitting in a repository.
  • Debugging interests you more than getting a first version working.
  • Here you will be given real work before you feel ready for it, and that unsettles a lot of good students.
  • You would rather ask than guess when something is not clear.

What we offer

  • Your code running on vehicles in the city, not sitting in a drawer.
  • Direct mentoring from the engineers who built the vehicle and the software.
  • A real chance of joining the team afterwards.
  • 100% on-site work in Seville.

What the process looks like

  1. Intro call with our team, 30 minutes.
  2. Technical conversation about something you have programmed, ideally with hardware attached.
  3. A morning in Seville with the team and the test rig.

These steps can be completed in ten days.
