Job description

Senior Electrical Engineer – SmartPlant 3D (SP3D) supports the development of the SMR-300, Holtec's next-generation small modular reactor. This role leads cable routing and raceway design for electrical power, I&C, and communication systems, including cable tray and conduit layouts, routing strategy development, and multidisciplinary coordination. The position is responsible for ensuring designs meet applicable codes, standards, and constructability requirements while leveraging SmartPlant 3D (SP3D) to support project execution from design through construction.

Location: Almondsbury Bristol, UK - Relocation Assistance Available!

Primary Responsibilities

• Lead cable routing design for the SMR-300 plant across electrical power, I&C, and communications systems.
• Develop routing design approach and coordinate design criteria/inputs (separation, fire area routing considerations, congestion management, constructability, maintainability).
• Execute and/or oversee raceway design including cable tray and conduit layout, routing constraints, and installation considerations.
• Provide raceway sizing inputs (tray sizing/fill inputs, conduit sizing inputs, routing quantities/support needs as required by project workflow).
• Coordinate and own penetration coordination (locations, routing paths, interface with civil/structural and other disciplines) and ensure routing is consistent with building/structural constraints.
• Produce/review routing deliverables (routing layouts, design notes/details, routing reports, model-based outputs, design change documentation) and ensure technical accuracy and quality.
• Perform and/or oversee cable routing and raceway layout work in SmartPlant 3D (SP3D).
• Lead/participate in model reviews; drive clash/congestion resolution and ensure routing content supports downstream construction and installation sequencing needs
• Provide technical direction, mentoring, and quality oversight for entry-level engineers supporting cable routing/raceway deliverables.
• Review/check work products for compliance with project requirements, applicable codes/standards, and internal procedures.
• Support construction/field execution as needed (RFI responses, routing conflict resolution, etc.)

Requirements

• Bachelor’s degree in Electrical Engineering (or closely related discipline) from an ABET accredited college or university.
• 10–15 years of progressive experience in electrical engineering design with significant experience leading cable routing and raceway design (nuclear preferred).
• Demonstrated ability to lead routing/raceway scope (quality, schedule, coordination) and provide technical direction to junior engineers.
• Working knowledge of codes/standards and engineering practices relevant to cable routing and raceway design (routing separation concepts, cable tray/conduit practices, grounding/bonding concepts, fire protection interfaces, and constructability considerations).
• Proficiency working in a 3D plant design environment; experience performing or directing routing development in SP3D (or equivalent with strong ability to ramp quickly).
• Strong technical writing and communication skills; able to coordinate across multi-disciplinary teams and external stakeholders.
• Strong planning, prioritization, and organizational skills; able to manage competing priorities and deliver results.

Preferred Qualificatioins

• Master’s degree preferred; PE preferred (or ability/interest to obtain).
• Nuclear project experience with familiarity supporting regulated design environments and formal design controls (QA, traceability, design reviews).
• Demonstrated experience coordinating routing and penetration interfaces with civil/structural, mechanical, piping/HVAC, I&C, and systems engineering.
• Experience supporting procurement/vendor submittal reviews impacting routing/raceway (equipment interfaces, installation constraints, vendor routing limitations).
• Experience supporting construction execution (walkdowns, constructability reviews, field change support, installation sequencing coordination).
• Familiarity with related tools/workflows often paired with SP3D delivery (model review tools, cable schedule databases, configuration management / document control processes).
