Amazon is looking for a hands-on Controls Software Engineer to develop the software platform behind its next-generation warehouse automation systems.

In this role, you'll design and deploy reusable control software using CODESYS V3, develop robust state-machine based control logic, integrate real-world automation hardware, and help scale a modular platform across Amazon's global fulfillment network.

What We're Looking For:

  • Strong CODESYS V3 or Beckhoff TwinCAT experience
  • Expert-level Structured Text programming
  • State machine architecture and machine sequencing expertise
  • Object-oriented PLC development experience
  • EtherCAT hardware integration experience
  • 5+ years building production machine control systems

Bonus Experience:

  • Conveyor, robotics, warehouse automation, or material handling systems
  • IO-Link integration
  • JSON/configuration-driven applications
  • Electrical drawings and commissioning support

Ideal Candidate: A controls engineer who naturally thinks in state machines, understands industrial hardware, asks the right technical questions before coding, and can build scalable software for high-throughput automation environments.

GCS is acting as an Employment Business in relation to this vacancy.
