Our Green Gas Solutions team plays a crucial role in the safe operation and maintenance of biomethane plants across Yorkshire. We’re now looking for an experienced and motivated Senior Biomethane Technician (Mechanical) to join us and help keep our sites running safely, efficiently, and reliably.

You’ll be part of a skilled operations team, carrying out daily and weekly site tasks, supporting planned and statutory maintenance, diagnosing faults, and contributing to more complex project work across our biomethane assets.

As a Senior Biomethane Technician (Mechanical), you’ll take responsibility for the safe and reliable operation of mechanical assets across our biomethane process plants in the Yorkshire region:

• Maintaining mechanical assets in line with legislation, industry standards, and SGN procedures.
• Delivering operational and maintenance activities on equipment such as compressors, pumps, valves, and ancillary machinery.
• Carrying out planned preventive maintenance, including repairs, overhauls, shutdown work, PSSR inspections, lubrication, filter cleaning, seal checks, and replacement of wear items—always following LOTO, permit‑to‑work, and hazardous‑area procedures.
• Completing routine site checks, logging readings, identifying leaks, abnormal vibration, or equipment deterioration.
• Responding to alarms and downtime events, carrying out complex fault‑finding and restoring safe operation.
• Troubleshooting mechanical issues, including alignment checks, vibration/noise investigation, fluid level verification, and safe repair execution.
• Working closely with customers and stakeholders, including Gas Distribution Networks, contractors, suppliers, and internal teams.
• Participating in a standby rota to provide 24/7 emergency support.
• Travelling across a wide geographical area, working both independently and as part of a team.

The role will require close cooperation and communication with our commercial customers and other key stakeholders including Gas Distribution Network representatives, our key contractors and suppliers, internal departments as well our biomethane team.

This role works across a large geographical area, and you will be working as part of a team as well as on your own, depending on the work you are doing. You will be expected to participate in a standby rota to deliver a 24/7 out-of-hours emergency support service.

What you will need:

• A strong understanding of the mechanical engineering discipline within an operations and maintenance environment.
• NVQ Level 3 (or equivalent) and completion of a recognised apprenticeship in Mechanical Engineering (minimum 2 years’ experience).
• Motivation to learn, develop, and expand your technical and industry knowledge.
• Confident IT skills and the ability to use digital systems effectively.
• A safe, methodical approach to work, with the ability to react positively when required.
• Strong communication and customer‑service skills, consistently demonstrating SGN’s core behaviours.
• Flexibility to participate in a standby rota and attend sites outside normal working hours.
• Willingness to travel across Yorkshire and occasionally to other UK locations including London, the South East, and Scotland.
• A full valid driving licence.
