Field Service Specialist in Bristol

Citritek provides water safety monitoring for a wide range of clients – hospitals, banks, corporate offices, utility companies and more. We install wireless sensors that track water temperatures and conditions in real-time, helping buildings stay compliant with safety regulations and protecting people from waterborne infections. We're small (which means you'll really matter) and growing (which means there's scope to grow with us).

We're looking to expand our team to help manage and service our growing client base in the South. We will be looking to hire two candidates: one in the South East and one in the South West. If you are based in Bristol, Wiltshire, Gloucestershire, Berkshire, Hampshire, or Greater London - we want to hear from you!

Escape the office. Every week is different. We're looking for someone who'd rather be working on or visiting customer sites than stuck behind a desk. You'll visit a variety of sites across the UK – hospitals one day, a City of London bank the next, an industrial water treatment plant the day after. You’ll manage your own schedule, build relationships with site teams, and take real ownership of your work. This is a role for someone who wants autonomy and variety, not routine and micromanagement.

What you’ll actually do:

• Most of your time is spent on site – hospitals, corporate offices, data centres, industrial facilities – installing and configuring wireless sensor systems, water sampling and testing for Legionella compliance, routine maintenance and troubleshooting, and building relationships with facilities managers and estates teams.
• You’ll also handle some desk‑based work from home – writing up reports, supporting customers remotely, keeping documentation in order.

What we’re looking for:

• Good with people – you’ll meet facilities managers and site teams every day, and need to build trust quickly.
• Comfortable walking onto an unfamiliar site and figuring out what needs doing.
• Tech‑savvy – you’ll use apps, data systems, and spreadsheets daily. If you can build a pivot table, you’ll be fine.
• Practically minded – the kind of person who’d know how to turn off the water, top up a combi boiler, or put up a shelf without too much fuss.
• Happy to travel and stay away when the job needs it (typically 4‑5 per month, sometimes more).
• Self‑directed – you won’t have someone looking over your shoulder.

You might come from trades or technical roles, ex‑forces, field service, healthcare facilities, or somewhere else entirely. We’re open‑minded – attitude matters more than qualifications.

This role isn’t for you if:

• You want a predictable 9–5 in one location.
• You’re uncomfortable staying away from home regularly.
• You prefer constant supervision or direction to stay on track.

What you’ll need:

• Full UK driving licence (essential).
• Comfortable with travel across England and regular overnight stays (5‑6 per month).

What’s in it for you:

• Company vehicle.
• Home‑based when not on site – no commuting to an office.
• Genuine training and development in a specialist sector.
• Small company where your contribution really counts.
