Internship

Seville

Open

Mechanical Engineering internship

Design, build and break real parts on vehicles that go out on 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

This is not an internship where you watch. We design vehicles certified to EN 17860 that live seven years on the street, and we have our own test rig, so the loop between drawing a part and finding out whether it holds is short. You will be inside that loop: preparing tests, assembling, measuring, and writing down what happened when something failed.

You will have a senior engineer next to you and real work with a date on it. The interesting part is the failures. A part that breaks on the rig teaches you more in an afternoon than a term of theory, and here you get to see why with the part in your hands.

Responsibilities

  • Support part design and the preparation of test rig campaigns.
  • Assemble, measure and document what happens when a part fails.
  • Keep drawings, test records and documentation in order.
  • Take part in field testing with vehicles in real operation.

What we're looking for

  • Studying mechanical or industrial engineering, with a university internship agreement in place.
  • Fluent enough in CAD to draw a part and modify it.
  • Comfortable in a workshop, with tools and with getting your hands dirty.
  • Based in Seville or willing to relocate.

Counts in your favour

  • A student team: Formula Student, Moto Student or similar.
  • Any hands-on machining, welding or workshop experience.

You will fit here if

  • You want the work to be real, with the responsibility that comes with it.
  • Learning by taking something apart suits you better than learning by reading about it.
  • Here you will be asked what you think before you feel ready to answer, and that unsettles a lot of good students.
  • You would rather ask than guess when something is not clear.

What we offer

  • Direct mentoring from senior engineers with automotive experience.
  • Access to the test rig and to vehicles in real operation.
  • 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. Conversation about something you have built or taken apart.
  3. A morning in Seville with the team, the workshop and the test rig.

These steps can be completed in ten days.
