Job Description
** Join the Fusion and Modular Nuclear Business Unit!
** Assystem has an exciting opportunity for a Control Systems Engineer to join our expanding Fusion and Modular Nuclear (FMN) business unit. As leaders in the design and development of new technologies, you will have the opportunity to work across multiple cutting-edge projectsdeveloping technical solutions making net-zero power generation a reality.

Provide engineering expertise in the design, development and verification of control systems used in nuclear facilities. The role covers programmable logic controllers (PLCs), distributed control systems (DCS), safety-related I&C functions and supporting systems such as SCADA/HMI. The engineer ensures that control system implementations are safe, compliant and fully traceable to nuclear requirements throughout the project lifecycle.
** Your Mission:
*** Design robust control system architectures that seamlessly support plant operations, automated sequences, interlocks, and vital protection functions.
* Create high-quality technical documentation—including control philosophies, functional requirements, logic descriptions, cause-and-effect diagrams, and interface specifications.
* Configure and program PLC, DCS, and specialised control platforms in line with nuclear lifecycle standards and industry expectations.
* Collaborate closely with EC&I, process, mechanical, safety, and human-factors engineers to ensure unified and consistent system performance across all interfaces.
* Integrate intelligent control logic with SCADA/HMI systems, historians, networks, and field instrumentation for smooth and reliable operations.
* Apply best-practice alarm management aligned with EEMUA 191 and site strategies to ensure clarity, efficiency, and safety.
* Execute rigorous verification and validation activities—including peer reviews, simulations, software testing, FAT, SAT, and commissioning support.
* Develop comprehensive test specifications ensuring alignment with requirements, functional hazards, and safety classifications for full assurance.
* Maintain strong configuration control and software governance, managing versions, coding standards, and baselines within nuclear-grade quality frameworks.
* Over 55 years in nuclear engineering.
* Ranked among the top 3 largest nuclear engineering companies.
* Attractive social benefits, including an engaging Employee Committee and holiday bonuses.
* Ongoing training with numerous career opportunities.
* 70% of our managers are promoted internally!
* Hybrid work: 1-2 days remote per week.## My profile
*
* Skills and Experience:

*** Hands-on control systems engineering experience in regulated sectors—ideally nuclear, defence, energy, or similarly high-integrity environments.
* Proven ability to produce detailed control deliverables such as control philosophies, logic diagrams, and sequence descriptions.
* Skilled in interpreting P&IDs, process narratives, safety requirements, and mechanical schematics to inform accurate and efficient design.
* Strong understanding of PLC/DCS programming techniques including structured text, ladder logic, function block, and sequential function charts.
* Experienced in verification, testing, simulation, or model-based methods for validating control logic with precision.
* Knowledgeable in nuclear I&C lifecycle requirements and safety classifications, including industry standards like IEC 61513, IEC 60880, IEC 61508, and IEC 61226.
* Familiar with alarm management best practices and experienced in applying EEMUA 191 to improve operational clarity and performance.
