About the Role
Join a growing controls team delivering industrial control systems across power-generation projects. This is a full lifecycle role, taking projects from FDS/DDS and control design through PLC/HMI/SCADA development, FAT/SAT and on-site commissioning.
You'll work across diesel generator controls, switchgear, ATS/AMF systems, synchronisation, load sharing and power management, with a working pattern of approximately 70% office / 30% site.
Job Responsibilities
- Design, develop and commission PLC, HMI and SCADA systems.
- Produce URS, FDS/DDS/SDS, I/O lists, Cause & Effect and test documentation.
- Develop PLC code from initial design/conception, not just modifications.
- Integrate generator controllers, switchgear, ATS/AMF, synchronisation and load-sharing systems.
- Lead FAT/SAT, I/O checks, loop testing and site commissioning.
- Troubleshoot PLC/HMI/SCADA systems and industrial networks.
- Interface with protection relays, meters, breakers, UPS and BMS/EMS systems.
- Work closely with electrical design, project managers and clients.
- Produce handover documentation and provide client training/support.
- Support and mentor junior engineers where required.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
