Apply for this role

No account needed. One of us reads it before anything reaches the company.

The work

The arm has six axes and a hard requirement to stop within 120 milliseconds of a light curtain break. That requirement shapes everything.

You would own the motion firmware and the safety controller that watches it.

Worth knowing

  • On-site in Bristol, because the robots are here and you will want your hands on them.
  • There is a cold room on the ground floor and you will spend time in it.

Must have

  • Bare-metal or RTOS firmware in production
  • Motor control or motion planning
  • Reading a schematic and a scope trace

Nice to have

  • Functional safety, ISO 13849 or similar
  • Cold-chain or industrial environments
