About the role

Key responsibilities & impact

Integrate electronics devices, instruments, third-party devices, and subsystems into larger complex systems comprising RF, analogue, digital, optical, and mechanical elements.
Translate system-level requirements into practical integration architectures, interfaces, cabling, power, communications, and control schemes.
Develop system interconnects including cable assemblies, harnesses, RF connections, grounding, shielding, power distribution, and signal routing.
Perform system bring-up, commissioning, troubleshooting, fault isolation, and performance optimisation.
Identify and resolve integration issues involving grounding, EMI/EMC, signal integrity, timing, communications, power distribution, and environmental effects.
Develop and maintain system diagrams, interface control documentation, wiring diagrams, integration procedures, and configuration records.
Define and execute integration, verification, and validation test plans at subsystem and system level.
Use laboratory test and measurement equipment to diagnose system-level performance and integration problems.
Support installation, deployment, commissioning, and maintenance of systems in laboratory and operational environments.
Collaborate with electronics, software, FPGA, mechanical, optical, physics, and systems engineering teams for end-to-end integration.
Support supplier selection and integration of third-party equipment and externally developed subsystems.
Contribute to system risk management, failure analysis, reliability improvement, and continuous improvement activities.
Collaborate with team members to ensure deadlines are met.
Work within multidisciplinary teams of physicists, engineers, and technicians to develop solutions.
Adapt to changing circumstances and manage ambiguity effectively.

Requirements

What you’ll need

Bachelor’s degree or substantive equivalent experience in electrical engineering, systems engineering, electronic engineering, physics, mechatronics, or a related technical discipline.
Several years of relevant and progressive experience integrating complex multidisciplinary hardware systems.
Strong practical understanding of analogue, digital, RF, power, grounding, shielding, and signal integrity principles.
Experience integrating PCBs, embedded systems, instruments, sensors, actuators, and third-party equipment into larger systems.
Experience with system bring-up, commissioning, troubleshooting, and fault isolation.
Experience developing and interpreting system block diagrams, wiring diagrams, interface specifications, and technical documentation.
Experience with electrical interfaces and communications protocols such as Ethernet, serial, SPI, I2C, CAN, USB, or similar.
Experience designing or specifying cabling, connectors, harnesses, grounding, shielding, and power distribution.
Experience with testing, verification, and validation of complex systems and subsystems.
Experience using test and measurement equipment such as oscilloscopes, spectrum analysers, network analysers, signal generators, power meters, and digital multimeters.
Ability to diagnose issues across multiple engineering disciplines rather than within a single subsystem.
Ability to work effectively within highly collaborative, multidisciplinary engineering teams.
Experience integrating RF systems including amplifiers, mixers, oscillators, filters, attenuators, and frequency conversion equipment.
Experience integrating optical or electro-optical systems including lasers, photodetectors, modulators, and optical control hardware.
Experience with precision analogue electronics, low-noise systems, and high-resolution data acquisition.
Experience with FPGA-based and embedded control systems.
Experience integrating laboratory automation and instrumentation using software interfaces such as SCPI, serial communications, Ethernet, or APIs.
Familiarity with EMI/EMC design and troubleshooting.
Experience designing systems for long-term stability and operation under varying environmental conditions.
Experience with rack-mounted systems, equipment enclosures, thermal management, and power distribution.
Experience commissioning complex scientific, industrial, or quantum technology systems.
Experience solving complex multidisciplinary problems in highly technical and scientific environments.
Up to 10% travel, including international travel, may be required.
Able to use automated office equipment such as laptops, copiers, and printers.
Able to effectively engage in communications via phone, computer, or in person.
Able to sit, stand, walk, lift, and carry up to 10 kg.
