Job description

We're looking to grow our BioCH4nge field service team and this is a great opportunity for an engineer who wants to build a career within the biomethane sector.

The role will focus heavily on BioCH4nge and biomethane upgrading technology, supporting plants across the UK, Republic of Ireland and internationally.

You will be working directly with the equipment and process that takes biogas and upgrades it into grid quality biomethane, giving you exposure to both the mechanical and process side of renewable gas production.

This is not just a maintenance role. You will be involved in fault finding, planned and reactive maintenance, commissioning support, plant optimisation, performance improvement and working with both customers and our wider technical teams to keep biomethane plants operating reliably and efficiently.

Travel will be a major part of the role, with extensive work across the UK and Republic of Ireland, as well as international travel for training, technical support and site activities.

Due to the travel requirements of the role, applicants must already have the unrestricted legal right to work in both the UK and Republic of Ireland without requiring employer sponsored visas or work permits.

The biggest opportunity is the technical development available.

You will receive specialist training on BioCH4nge systems and biomethane upgrading technology, developing knowledge across areas such as gas treatment, compressors, membranes, analysers, instrumentation, controls and the wider upgrading process.

There will also be opportunities to cross train on CHP technology, giving you a broader understanding of the complete renewable energy process and opening up further progression opportunities within the business.

Previous biomethane experience would be beneficial, but it is not essential. We are more interested in finding someone with a strong engineering background, good fault finding ability, a practical mindset and the willingness to learn.

Experience with mechanical or electrical maintenance, compressors, rotating equipment, PLCs, instrumentation, gas systems, process plant or CHP would all transfer well into the role.

If you are looking to move into biomethane, develop into a specialist in upgrading technology and work in a sector that is continuing to grow rapidly, this is a very strong opportunity.
