Are you a software engineer who likes your code to move real machines? A major name in robotics... Read more
Are you a software engineer who likes your code to move real machines? A major name in robotics and automation is building out the team behind one of the largest robotic deployments anywhere - thousands of automated workcells running across high-volume operations - and is looking for a Controls Software Engineer to help keep that fleet fast, stable, and improving.
This isn't a traditional PLC seat. It's a software role that happens to live in a controls world. Most of the team came up through C and C++ and learned the control platform on the job - so what matters here is real software-engineering ability paired with hands-on experience around machines, motion, and hardware.
What you'll work on
Hunting down and fixing bugs and faults in control software running across a large fleet of deployed machinesPushing rate and throughput improvements through the servo, motion, and state-management layersGetting hands-on with hardware in the lab - servos, drives, sensors, vision, and conveyanceTracing problems through telemetry, logs, and alarms, and owning fixes from root cause to rolloutWriting the change documentation and runbooks that keep fleet-wide deployments safeThe live system is written in Structured Text (CODESYS) on Linux-based industrial PCs, with a move to modern C++ already in flight. It's a big, established codebase - strong software instincts matter as much as controls knowledge.
The two things that really matter
Genuine controls experience - you've written software that drives physical hardware: machine control, motion/servo, robotics, or embedded real-time systems.Strong software development in a modern lower-level language - C, C++, Rust, or Structured Text - with the discipline to work cleanly inside a large, mature codebase.Nice to have
Structured Text on any platform (CODESYS, TwinCAT, Allen-Bradley, Siemens)Embedded, real-time, or industrial software backgroundMotion/servo control, robotics, or pick-and-place / Cartesian workcell experienceSystem-level Linux; EtherCAT or other industrial fieldbusExperience keeping production or large-scale systems runningLevel
Open from strong mid-level engineers (3-5 years) who can own their work, through to seasoned engineers ready to plug straight in. The blend of controls exposure and software ability is what counts - not a specific title.
