Electrical and Controls Design Engineer

Our client is seeking an Electrical & Controls Design Engineer to support the development of advanced cooling technologies for data centres, AI/HPC, and industrial applications.

This is an R&D-focused role covering electrical system design, controls architecture, and instrumentation from early concept through prototype development and validation, with exposure to product industrialisation.

You will work closely with mechanical, software, and test engineers to define system-level electrical and controls strategies for next-generation cooling products.

Key Responsibilities

Electrical System Design

• Design electrical architectures for R&D prototypes and future production systems, including:

  • Power distribution

  • Control and safety circuits

  • Protective devices and panel layouts

• Produce electrical schematics and wiring diagrams using AutoCAD Electrical (or similar).

• Select electrical components such as:

  • Relays, breakers, contactors

  • VSDs, EC fans, actuators, compressors

  • Power supplies and safety hardware

• Ensure designs comply with CE and applicable safety standards.

• Support design reviews, risk assessments (FMEA), technical documentation, and BOM creation.

Controls & Instrumentation

• Define and specify sensors and instrumentation for refrigerant, air, and water systems, including:

  • Temperature, pressure, flow, humidity, level, and differential pressure

• Develop controls architecture diagrams, I/O lists, and cable schedules in collaboration with controls/software engineers.

• Provide technical input to control logic, sequencing, and system behaviour.

• Specify and review communication methods and interfaces:

  • Analog/digital I/O, Modbus, BACnet, PWM, 0-10 V

• Support panel builders and software teams with clear I/O maps, signal definitions, and instrumentation specifications.

• Review R&D test data to validate sensor accuracy and control performance, recommending improvements where required.

Required Experience

• Degree in Electrical Engineering, Controls Engineering, Mechatronics, or related discipline.

• 3+ years' experience in electrical design, controls design, or instrumentation engineering.

• Strong ability to design and interpret electrical schematics and control circuits.

• Experience selecting and integrating sensors and instrumentation.

• Understanding of control theory fundamentals.

• Familiarity with:

  • VSDs, EC motors

  • Valves, actuators, relays

  • Analog and digital I/O

  • Industrial wiring practices

• Ability to work effectively in cross-functional R&D teams.

• Strong technical documentation and communication skills.

Desirable (Not Essential)

• Exposure to UL standards (UL1995, UL508A, UL 60335-2-40).

• Experience with HVAC/R or refrigeration systems.

• Hands-on experience with instrument calibration or data acquisition.

• Familiarity with PLC environments (e.g. Carel, WebCTRL).

• Knowledge of data-centre cooling architectures.
