FIELD SERVICE TECHNICIAN
Mobile Diesel Fuel Polishing
Keep the lights on — literally. Fuel Perfect is San Antonio's leading mobile fuel polishing and conditioning company, helping hospitals, data centers, banks, and mission-critical facilities keep their backup power systems running when it matters most. We're growing, and we're looking for a hands-on, reliable Field Service Technician to join our team.
No fuel polishing experience? No problem. We'll train the right person — what we're really looking for is someone mechanically curious, dependable, and great with people.
WHAT YOU'LL DO
- Travel to customer sites across San Antonio and throughout Texas to perform on-site diesel fuel polishing and tank conditioning.
- Set up and tear down hoses, pumps, and filtration equipment safely and efficiently.
- Operate our fuel polishing system through the process while following our Method of Procedure.
- Conduct routine inspections and preventive maintenance on mechanical and filtration equipment.
- Collect fuel samples for lab testing and document before/after results for customers.
- Operate a company vehicle safely to transport equipment between job sites.
- Communicate clearly to customers and represent Fuel Perfect professionally on-site.
- Maintain accurate service records, inspection reports, and job documentation.
- Follow all safety protocols related to diesel fuel handling, spill prevention, and PPE use.
- Assist with equipment maintenance and inventory at our shop between jobs.
WHAT WE'RE LOOKING FOR
- Valid driver's license with a clean driving record.
- Willingness and ability to travel, including occasional overnight trips.
- General mechanical aptitude — comfort working with pumps, hoses, and small mechanical systems.
- Willingness to learn diesel fuel systems, generator basics, and industrial maintenance practices.
- Strong customer service skills and a professional, can-do attitude.
- Ability to work independently and manage your schedule across multiple job sites.
- Comfortable working both solo and as part of a two-person crew depending on the job.
- Basic tech comfort — you'll use a phone/tablet for scheduling, photos, and reporting.
- Plus, but not required: OSHA certification, HAZMAT handling experience, or a CDL.
PHYSICAL REQUIREMENTS
- Ability to lift and carry up to 50 lbs (hoses, pumps, equipment)
- Comfortable working outdoors in varying weather conditions.
- Ability to bend, kneel, and work in mechanical/utility areas and in tight spaces.
- Standing and walking for extended periods during service calls.
SCHEDULE & TRAVEL
- Flexible, 20–30 hours per week depending on workload.
- Days vary week to week — no fixed schedule.
- No weekends required.
- Based out of San Antonio, with day travel required to job sites across Texas.
- Overnight travel is possible a couple of times per month — hotel and per diem provided.
WHY FUEL PERFECT

No two days look the same — you'll work with clients like banks, medical facilities, and data centers, gaining experience that few technicians get. As part of our small, tight-knit team, your work is seen and valued, and as we grow, so will the opportunities — including the chance to grow into management positions for the right person who wants to build a career, not just work a job.
