Full job description

Operations Technicians - Electrical, Mechanical, and Instrumentation x3 roles (Chelmsford)

£44,642 to £52,519 (depending on experience) + up to 6% bonus + access to liveried vehicle

Up to 10-15% additional earnings through overtime and standby

Chelmsford (and the surrounding area)

You’ll work across a defined regional patch (East 5), covering sites from Essex through to the Thames Estuary, with travel required across the area five days a week.

About us

National Gas is securing Britain’s energy. We transport gas throughout Great Britain, repair and maintain gas pipelines, and manage the meters that allow millions of homes and businesses to access the energy they need. We are the national gas network, providing secure energy to power Britain, achieve net zero, and maintain our industrial competitiveness.

About the role

Keep critical energy infrastructure running safely and reliably. We’re hiring Operations Technicians to deliver hands-on support across compressor stations, pipelines and AGI assets.

These are predominantly pipelines-focused opportunities within our operations team, where you’ll maintain and support electrical, mechanical, and instrumentation systems across operational gas infrastructure. You’ll carry out fault finding, repairs and performance improvement, playing a key role in both routine maintenance and emergency response.

Opportunities are available across electrical, mechanical, and instrumentation disciplines, with scope to build cross-discipline experience beyond your core specialism. These are field-based roles, working closely with technicians and wider teams to keep assets safe, compliant and performing at their best.

Why this role matters

The national transmission system underpins essential energy supply. Your work directly protects asset integrity, keeps gas flowing, and supports safe, uninterrupted operations.

You’ll take ownership of high-risk activities, support emergency response, and influence how sites operate - with real impact on safety, reliability and performance.

What you'll be doing

Manage installation, inspection, commissioning and maintenance of plant and pipeline assets
Manage maintenance across plant, including rotating equipment, valves and pressure systems
Deliver fault diagnosis and repair to maximise availability and reliability
Lead safe systems of work, issuing permits and defining isolations
Maintain accurate asset, maintenance and operational records in line with regulatory requirements
Support commissioning of new assets and contribute to minor design improvements
Respond to incidents and support emergency operations, including standby cover
Oversee contractor activity to ensure safety and technical compliance
Participating in a standby rota once fully trained, typically one week in every four or five

What you'll bring

This role would suit someone who brings strong field-based engineering experience and thrives in disciplined, safety-led environments.

Essential

Proven maintenance and operations experience in electrical, mechanical, or instrumentation engineering (or similar process industry)
Experience diagnosing faults and maintaining plant and equipment in hazardous or safety-critical environment
Strong working knowledge of safe systems of work, including permits and isolations
Understanding of process plant operation and cross-discipline equipment interaction
Knowledge of relevant technical and health & safety legislation
Recognised engineering apprenticeship or equivalent, plus Level 3 qualification (e.g. NVQ, City & Guilds)
Full UK driving licence

Desirable

CompEx certification relevant to your discipline (EX01–04 or EX11)
Electrical certifications such as 18th Edition, Inspection & Testing, or PAT Testing
Experience with rotating plant, compressors, pipelines etc.
Experience with DSEAR-regulated environments
Exposure to cyber security standards (e.g. IEC 62443)
Experience supporting construction and commissioning projects

Security clearance

The successful candidate must be able to achieve and maintain Security Check (SC) security clearance for this role.

Many of the positions within our company are subject to national security clearance and Trade Control restrictions. This means that your eligibility for certain roles may be affected by your place of birth, nationality, current or former citizenship, and any residency you hold or have held. Further details are available at United Kingdom Security Vetting: clearance levels - GOV.UK (www.gov.uk).

What we offer

Competitive salary and annual performance bonus
Double-match pension scheme (max. company contribution 12%)
Generous holiday allowance (26 days + bank holidays)
Flexible benefit scheme, inc. private healthcare, dental insurance, technology plans, and more
Financial protection with 10x salary death in service and financial support if you’re unable to work due to long-term illness or injury
