EC&I Jobs Cumbria: Sellafield, Barrow and Beyond

Published 14 August 2026 · Cumbria Works editorial

Compare EC&I careers at Sellafield, Barrow and across Cumbria, including design, maintenance, control systems, HV/LV skills and salaries.

EC&I jobs in Cumbria span electrical, control and instrumentation work in some of the UK’s most demanding engineering environments. However, a design role supporting Sellafield can look very different from electrical commissioning in Barrow or a PLC-focused position with a supply-chain contractor.

What does EC&I cover?

EC&I stands for electrical, control and instrumentation. Employers may also use C&I, ECI, electrical controls or control systems in job titles, so searching only for “EC&I Engineer” can miss relevant vacancies.

The discipline commonly covers:

  • Electrical distribution, protection and equipment
  • Instrument selection, installation and calibration
  • PLC, SCADA and distributed control systems
  • Control panels, motor control centres and drives
  • Functional testing and commissioning
  • Fault diagnosis and planned maintenance
  • Design calculations, drawings and technical specifications
  • Safety, configuration and engineering change control

Job boundaries vary. One employer may combine electrical and instrumentation responsibilities, while another separates electrical power, software, commissioning and maintenance into specialist teams.

Sellafield: plant, safety and long-term asset work

EC&I work connected with Sellafield is generally centred on complex industrial facilities and their supporting infrastructure. Opportunities can sit with Sellafield Ltd or with engineering consultancies, delivery partners and specialist contractors.

Design engineers may work on equipment specifications, cable schedules, control philosophies, instrument schedules, schematics and design substantiation. Depending on the project, they may support modifications to an existing plant rather than start with a blank-sheet design.

Maintenance and site-based roles place more emphasis on asset condition, fault finding, testing, calibration, isolations and returning equipment safely to service. Engineers working on ageing or modified assets also need to understand configuration control and the relationship between installed equipment and approved documentation.

PLC and SCADA opportunities may involve software changes, obsolescence management, testing or integration with existing systems. Candidates should check the vacancy carefully for the named platforms and whether the employer wants programming expertise, independent assurance or broader control-system engineering.

For HV/LV positions, look beyond the headline voltage level. The specification may require experience of protection, switchgear, distribution studies, safe systems of work, commissioning or operational authorisations. Never assume an existing authorisation automatically transfers between employers or sites.

The current site vacancy snapshot does not contain a role explicitly titled EC&I at Sellafield. It does include Sellafield and supply-chain vacancies in safety, project controls and site delivery. That is a reminder that EC&I recruitment can be project-led and that relevant roles may appear under electrical, commissioning, systems, maintenance or control-system titles.

Barrow: integration and electrical commissioning

The current vacancy data shows the clearest immediate EC&I demand around Barrow-in-Furness. There are five listing entries with the exact title Senior Commissioning Engineer – Electrical, advertised through BAE Systems and BAE Critical Skills. Repeated entries may be separate campaigns or duplicated listings, so candidates should confirm the number of distinct posts with the advertiser.

Where salaries are displayed, two Senior Commissioning Engineer – Electrical entries show £50,873.44 and £55,048.18. Other listings with the same title do not publish a salary, so these figures should be treated as examples from the present adverts rather than a market-wide pay range.

Barrow also has a Principal Software Engineer (Control Systems) listing at £47,700.42 and an Instrument Technician vacancy at £47,958.23. Related adverts include systems engineering, software assurance and communications integration roles.

This mix points candidates towards three distinct career routes:

  • Electrical commissioning: proving that equipment and systems have been installed correctly, completing tests, recording evidence and resolving defects.
  • Control systems: developing, integrating or assuring software-led control functions and their interfaces.
  • Instrumentation: maintaining, testing and diagnosing measurement and control equipment in an operating industrial environment.

Barrow roles may use “systems”, “software”, “integration” or “commissioning” rather than EC&I. Read the responsibilities and essential criteria, not just the title.

The wider Cumbria supply chain

Supply-chain employers can offer broader exposure than a large site organisation because one engineer may support several work packages or clients. Opportunities can include concept and detailed design, panel manufacture, installation, commissioning, maintenance and technical consultancy.

Workington, West Cumbria and the Furness area can all provide access to nuclear, defence and advanced-manufacturing projects. Current vacancies also show engineering and design recruitment in locations including Workington, Cockermouth, Ulverston, Kendal and Carlisle, although not every engineering role is EC&I-specific.

For PLC and SCADA candidates, supply-chain roles may value practical delivery experience particularly highly. Useful evidence includes:

  • PLC or SCADA platforms used and your level of responsibility
  • I/O schedules, control narratives or cause-and-effect work
  • Factory and site acceptance testing
  • Network or industrial communications knowledge
  • Commissioning records and fault-resolution examples
  • Work on upgrades, migrations or obsolete equipment

For design positions, prepare examples showing how you selected equipment, checked calculations, managed interfaces and produced controlled documentation. For maintenance roles, quantify the complexity of faults and explain how you worked safely within permit, isolation and escalation arrangements.

Qualifications, competence and clearance

Common routes into EC&I include an electrical or electronic engineering degree, HNC/HND, apprenticeship or technician qualification. The appropriate route depends on whether the vacancy is focused on design authority, hands-on maintenance, software, commissioning or leadership.

Employers may ask for sector experience, but candidates from manufacturing, utilities, process industries, rail, marine or other regulated environments can still have transferable skills. Make the connection explicit by highlighting controlled change, safety-critical testing, technical records and work under formal procedures.

Some nuclear and defence positions are subject to security, identity, residency or site-access checks. Requirements differ, so check the individual advert rather than assuming that holding one clearance guarantees eligibility elsewhere.

Hiring managers should also avoid treating EC&I as a single skill set. A strong PLC programmer is not automatically an HV protection specialist, while an experienced maintenance technician may need support before taking design-signatory responsibility. Clear adverts should identify the equipment, project stage, site expectations and required level of technical authority.
