Job Title: I&C Sensor Engineer
Location: Site at Sizewell B & Cranefield
Travel: All transport covered by client
Role Type: Engineer (not Technician)
Required: High Security clearance at least (SC Level)
Role Purpose
To support the maintenance, calibration, integration, and operational performance of nuclear-grade instrumentation sensors and associated control systems for Sizewell B. The role includes specification, programming, testing, and linking of field instrumentation to control and automation functions.
Key Responsibilities
* Perform engineering activities related to field sensors, including installation design, calibration, configuration, and life-cycle monitoring.
* Work with temperature sensors including PT100 RTDs and thermocouples (IEC 60751 / IEC 60584).
* Configure and verify flow transmitters, level and pressure transmitters in safety and non-safety classified systems.
* Integrate sensors into control command systems, ensuring correct data acquisition and stable signal processing.
* Develop, modify, or troubleshoot control system logic and automation sequences to ensure correct process response to instrumentation inputs.
* Ensure sensor wiring, shielding, grounding, and routing are compliant with I&C and EMC nuclear standards.
* Participate in loop checks, commissioning, validation, and testing activities on-site at Sizewell B.
* Support failure analysis (FMEA), diagnostics, and maintenance strategies for ageing or drifting instrumentation.
* Maintain all documentation according to nuclear safety, configuration control, and QA procedures.
Technical Skills Required
* Strong knowledge of thermocouples and PT100 (industrial and/or nuclear grade).
* Experience with flow, level, and pressure transmitters (e.g., differential pressure, vortex, ultrasonic, radar).
* Ability to program or configure control command / PCS / DCS / PLC systems (e.g., Ovation, Foxboro, Siemens, Rolls-Royce Spinline, teleperm, or equivalents).
* Understanding of sensor signal conditioning and upgrading or integrating new measurement chains.
* Familiarity with industrial automation protocols (4–20 mA, HART, Foundation Fieldbus, Profibus, Modbus, etc.).
