What refinery jobs are and who hires for them

A refinery job is work at an oil refinery — a large industrial facility that turns crude oil into gasoline, diesel, jet fuel, and other products. Refineries operate 24 hours a day, 7 days a week, so they hire for day shifts, night shifts, and rotating schedules. The work ranges from operating equipment and monitoring systems to maintenance, lab testing, administration, and security.

Major employers include companies like Chevron, ExxonMobil, Shell, Valero, and Phillips 66, which operate refineries across the United States. Smaller regional refineries also hire regularly. Most refineries are located in Texas, Louisiana, California, Oklahoma, and along the Gulf Coast, though refineries exist in nearly every state. Some refineries are owned by the oil company itself; others are independent operations that process crude oil for multiple clients.

Refinery work is unionized at many facilities, meaning wages, benefits, and working conditions are set by contract between the company and the union — typically the United Steelworkers or the International Union of Operating Engineers. Non-union refineries set their own pay and terms. Both types hire entry-level workers, though union shops often require apprenticeships or training programs.

Key Takeaways

  • Refinery jobs range from equipment operators and maintenance technicians to lab analysts and control room operators, with entry-level positions available to people without prior refinery experience.
  • Starting pay at refineries varies by location, employer, and union status, but entry-level positions typically start between $18 and $28 per hour, with experienced operators earning significantly more.
  • Most refineries require a high school diploma or GED, a valid driver's license, and the ability to pass a background check and drug screening before hire.
  • Union refineries often offer paid apprenticeships or training programs that last 3 to 5 years, during which you earn while you learn the job.
  • Refinery work involves shift work, on-site safety training, and exposure to industrial hazards, so physical fitness and comfort with safety protocols are essential.

Common refinery job titles and what they involve

Equipment Operator is one of the most common entry-level roles. You monitor gauges, control valves, and adjust processes to keep crude oil moving through the refinery and turning into finished products. The work is mostly in a control room or at equipment stations, watching instruments and responding to changes. Most operators work 12-hour shifts on a rotating schedule.

Maintenance Technician repairs and maintains the machinery, pipes, pumps, and systems that keep the refinery running. This role requires mechanical skill and often involves climbing, welding, and working in tight spaces. Many refineries hire maintenance technicians as apprentices and train them on the job. Instrument Technician roles focus specifically on the sensors, gauges, and control systems that tell operators what is happening in the refinery.

Laboratory Analyst or Quality Control Technician tests samples of crude oil, intermediate products, and finished fuel to make sure they meet specifications. This work is usually day shift and requires attention to detail and basic chemistry knowledge. Safety Inspector and Environmental Technician roles focus on compliance, hazard prevention, and regulatory reporting.

Administrative roles like Scheduler, Planner, and Clerk also exist at refineries. These positions involve coordinating work, managing records, and supporting operations from an office. Security, janitorial, and food service roles are also available at most facilities.

Pay, benefits, and shift schedules

Entry-level refinery pay varies significantly by location and employer. Non-union refineries in rural areas may start at $18 to $22 per hour for operators or technicians. Union refineries and those in high-cost areas like California or the Gulf Coast typically start between $24 and $28 per hour. After 3 to 5 years of experience, operators and technicians at union shops often earn $35 to $50 per hour or more, depending on the contract.

Most refineries offer health insurance, a 401(k) or pension plan, paid time off, and shift differentials — extra pay for working nights or weekends. Union refineries typically offer more generous benefits packages. Some refineries offer tuition reimbursement for continuing education or certifications. Overtime is common at refineries, especially during maintenance shutdowns or when production ramps up, and overtime pay is usually time-and-a-half or double-time.

Shift schedules vary by refinery. Many use 12-hour rotating shifts — you might work four days on, then four days off, with the day/night rotation changing every week or month. Others use 8-hour shifts with traditional day, evening, and night rotations. Some administrative and lab roles offer standard 8-to-5 schedules. Refineries rarely close for holidays, so you may work Thanksgiving, Christmas, and New Year's, though you receive holiday pay or time off in exchange.

Education and training requirements

Most refineries require a high school diploma or GED for entry-level positions. Some roles, particularly lab analyst or instrument technician positions, may prefer some college coursework or a certificate in chemistry, electronics, or industrial maintenance, but this is not always required. Many refineries hire people without prior refinery experience and train them on the job.

Union refineries often run formal apprenticeship programs that last 3 to 5 years. During an apprenticeship, you work full-time at the refinery while attending classroom instruction one or two days per week. You earn a wage throughout — typically starting at 50 to 60 percent of a journeyman's wage and increasing each year. At the end, you earn a recognized certification. Non-union refineries may offer informal on-the-job training instead, where a senior technician teaches you over weeks or months.

Some refineries sponsor employees to earn certifications in areas like process technology, instrumentation, or safety. The Certified Process Technician (CPT) credential, offered through the Manufacturing Institute, is recognized across the industry and can improve your pay and job prospects. Many community colleges near refineries offer CPT programs, sometimes with refinery sponsorship.

How to find and land a refinery job

Start by visiting the careers page of refineries near you. Major companies like Chevron, ExxonMobil, Shell, Valero, and Phillips 66 post openings on their websites. Search "[Company Name] careers" or "[Company Name] jobs" to find their process portal. You can also search job boards like Indeed, LinkedIn, and Glassdoor for "refinery operator," "maintenance technician," or "refinery jobs" plus your city or state.

Contact the refinery directly. Call the main number and ask for Human Resources or Recruitment. Many refineries have a dedicated hiring line or email address. Asking to speak with someone directly can sometimes move your process forward faster than explore online alone. Local unions also post apprenticeship openings — search "[Your State] Steelworkers apprenticeship" or "[Your State] Operating Engineers apprenticeship" to find union training programs.

Prepare for a multi-step process. Most refineries require a written process, a phone or video interview, an in-person interview, a background check, a drug screening, and sometimes a physical fitness test or medical exam. The entire process can take 4 to 8 weeks. Be ready to discuss your work history, why you want refinery work, and your comfort with shift work and safety protocols.

Safety requirements and working conditions

Refinery work is classified as hazardous. You will be exposed to high temperatures, pressures, toxic chemicals, and heavy machinery. Every refinery requires extensive safety training before you start work and ongoing training throughout your employment. You must wear personal protective equipment — hard hat, safety glasses, steel-toed boots, and sometimes respirators or chemical suits — depending on where you are working.

All refineries conduct drug screening before hire and random drug testing during employment. You must pass a background check with no felony convictions (some refineries have specific restrictions). You need a valid driver's license and may need a commercial driver's license (CDL) if the job involves transporting materials. Some refineries require a security clearance or work authorization verification.

Refinery work involves standing for long periods, climbing, lifting, and working in confined spaces. Physical fitness helps, though most refineries do not require you to be an athlete — they want to know you can handle the demands of the job. Heat stress, noise, and fatigue from shift work are real concerns. Many refineries have occupational health programs and employee information programs to support worker wellness.

Union versus non-union refinery work

Union refineries typically offer higher starting pay, more structured training, better benefits, and stronger job security. If you are hired at a union refinery, you usually enter an apprenticeship program, earn while you learn, and graduate into a journeyman position with a set wage scale. Union contracts protect you from sudden layoffs and set clear rules for scheduling, overtime, and grievances. The downside is that union apprenticeships are competitive — you may wait months or years to be called in.

Non-union refineries hire faster and may offer more flexibility in scheduling and advancement. However, pay is often lower, benefits may be less generous, and there is no contract protecting your job or setting wage increases. You have less recourse if you believe you are treated unfairly. Some non-union refineries are excellent employers; others are not. Research the specific refinery and read reviews from current and former employees before explore.

Many refineries are transitioning toward more contract and temporary workers, especially for maintenance work. Contract positions may offer lower pay and no benefits, but they can be a way to get your foot in the door and move into a permanent role later.

Frequently Asked Questions

Do I need experience to get hired at a refinery?

No. Most refineries hire entry-level workers without prior refinery experience, especially for operator and maintenance apprenticeships. You need a high school diploma or GED, a valid driver's license, and the ability to pass a background check and drug screening. Prior experience in manufacturing, maintenance, or military service can help, but it is not required.

What is the difference between an operator and a technician?

Operators monitor and control the refinery processes — they watch gauges and adjust valves to keep production running. Technicians maintain and repair the equipment and systems. Both are skilled roles, and both start as apprentices at union refineries. Technicians often earn slightly more because the work requires more specialized mechanical skills.

Can I work day shift only at a refinery?

Most production roles at refineries require shift work because the facility runs 24/7. However, some administrative, lab, and office roles offer day-shift-only schedules. If shift work is not possible for you, ask during the interview whether day-shift positions are available in your area of interest.

How long does it take to become a journeyman operator or technician?

At union refineries, apprenticeships typically last 3 to 5 years. You work full-time and attend classroom instruction one or two days per week. At non-union refineries, informal training may take 1 to 3 years, depending on the company and your role. After you complete training, you are considered a journeyman and earn the full wage for that position.

What happens if I fail the drug screening?

A positive drug screening will disqualify you from hire at virtually all refineries. Some refineries may allow you to reapply after a waiting period, but this varies. If you are taking prescription medications, disclose them before the screening — the testing company will account for legitimate prescriptions.
