Senior Mechanical Engineer — Drivetrain & Durability (m/f/d)

Find out why a field robot keeps breaking its drivetrain, redesign it so it stops, and build the test rigs that prove it before the next machine goes out.

  • Part-time
  • Contract
  • Remote
  • Based in Vietnam
Apply for this role

Our field robot works European farms: 200 kg, four wheels, battery powered, ten to twelve hours a day on rough ground, with a drilling tool on board. The third prototype generation keeps breaking shafts and drivetrain components. We want that settled rather than patched again.

What good looks like

The robot stops breaking shafts, and you can show why on a rig instead of arguing about it. The durability plan you write is what the next failure gets measured against.

What you do

  • Analyse the broken parts. Failure mechanism, fracture pattern, load path.
  • Redesign the drivetrain: shafts, shaft-hub connections, bearings, gearboxes, overload protection.
  • Rework the wheel suspension for oscillating axles and uneven ground.
  • Select the bought-in components — gearmotors, torque limiters — and be able to defend the choice.
  • Develop and build component-level test rigs, and validate against the duty cycle.
  • Write the durability plan: load cases, acceptance criteria, what counts as passed.
  • Work with the engineering teams in Vietnam and Germany.

What you bring

  • 8+ years in mechanical engineering on machines that move and carry load.
  • A field failure you solved, not just described.
  • Fatigue calculation to DIN 743 or FKM, and L10 bearing life.
  • Shaft-hub connections, press fits, tolerances, GD&T.
  • Endurance test rigs you have built and run.
  • Professional CAD: Fusion, SolidWorks, Inventor, NX or Creo.
  • Technical English.

Nice to have

  • Agricultural or off-road machinery.
  • Electric drive selection.
  • Machinery safety standards: EN ISO 12100, ISO 25119, ISO 18497.
  • Working with manufacturers in Vietnam.

Terms

  • About 2–3 days a week, roughly six months, extendable.
  • Fully remote.
  • Based in Vietnam: that is where the team you work with every day sits.
  • Working language English.

What we will ask you

Three questions come with the form. They are the same ones we ask on every channel, published here so you can think about them before you write, rather than after.

  1. A field failure you traced to root cause. What was the mechanism, and how did you confirm it rather than assume it?
  2. How do you size a shaft that has already failed once in service?
  3. A test rig you specified. What did it have to reproduce, and what did you deliberately leave out?

One form, no login, no portal. We read every application and reply to all of them.
