Up to £45,000 Basic Salary + Overtime + Benefits

Join a Team That Values Quality, Development and People

At Genex, we're building more than a compliance business. We're building a team of skilled professionals who take pride in delivering high-quality work, supporting each other and continuously developing their expertise.

As part of the growing Obsequio Group, Genex specialises in water hygiene, pre-commission cleaning, flushing, commercial plumbing, ductwork cleaning and air hygiene services. From major data centres and hospitals to complex commercial developments, our engineers play a vital role in delivering safe, compliant and efficient building systems across the UK.

We're growing rapidly and are now looking for an experienced Flushing Engineer to join our team.

If you're looking for a role where you'll be trusted, supported and given genuine opportunities to progress, we'd love to hear from you.

Why Join Genex?

• Competitive salary with overtime opportunities
• Company van, uniform, tablet provided and paid for accommodation when on the job
• 25 days annual leave plus bank holidays
• AVIVA pension scheme
• Funded training, industry qualifications and apprenticeship programmes
• Clear opportunities for career progression
• Work on high-profile projects across the UK
• Supportive team culture where your contribution matters
• Part of a growing national business with ambitious plans

At Genex, we believe our engineers deserve good support. We invest in our people, promote from within wherever possible and create an environment where individuals can build rewarding long-term careers.

Development isn't just something we talk about, it's something we actively invest in. Through ongoing training, recognised industry qualifications and funded apprenticeship programmes, we'll help you build your skills, expand your knowledge and take the next step in your career.

The Opportunity

As a Flushing Engineer, you'll be responsible for delivering pre-commission cleaning, flushing and water treatment services across a variety of commercial and industrial projects nationwide. You'll work with experienced colleagues on technically challenging projects, using industry-leading equipment and processes to ensure systems are commissioned safely, efficiently and in full compliance with industry standards. No two days are the same. One week you could be supporting the delivery of a major data centre project, the next carrying out chemical cleaning and system treatment works for a hospital or commercial development. You'll have the autonomy to do what you do best, whilst benefiting from the support of a knowledgeable management team that's committed to your development.

Key Responsibilities

• Collection and recording of system data and test results
• Maintenance of equipment, vehicles and site documentation
• Ensuring all works are completed safely and in line with company procedures and industry standards
• Working closely with colleagues, clients and site teams to deliver exceptional service

What We're Looking For

Essential

• Experience within flushing, water treatment or building services
• Knowledge of pre-commission cleaning and closed-system treatment
• Experience operating flushing and filtration equipment
• Good understanding of heating and chilled water systems
• Strong commitment to health, safety and quality standards
• Full UK driving licence
• Willingness to travel and stay away when required

Desirable

• Experience with conventional and CPC filtration flushing
• Knowledge of BSRIA BG29 and BG50 guidance
• Legionella Risk Assessor qualification
• Water hygiene experience
• Microsoft Office skills

Don't worry if you don't tick every box. If you've got relevant experience and a positive attitude, we'd still love to hear from you.

We're proud of the culture we've built. Our people are trusted to do their jobs, supported when they need help and recognised for the contribution they make. We believe in open communication, teamwork and continuous improvement. Whether you've been with us for ten years or ten weeks, your ideas and input matter. As we continue to grow, we're committed to maintaining the supportive, down-to-earth culture that's helped make Genex what it is today.

Ready for Your Next Challenge?
