What is a refinery sampler?

Refinery samplers are professionals responsible for collecting samples of raw materials, intermediate products, and finished products at oil refineries or chemical plants. Their main objective is to ensure that samples are collected safely and accurately for laboratory analysis, which helps monitor product quality and process efficiency. Refinery samplers must follow strict safety and sampling procedures to avoid contamination and maintain representative samples. They often work in hazardous environments and are trained to use specialized equipment. Their work is essential to compliance with industry standards and regulations.

What are the key skills and qualifications needed to thrive as a refinery sampler, and why are they important?

To thrive as a Refinery Sampler, you need knowledge of sampling procedures, attention to detail, and a high school diploma or equivalent, often accompanied by safety certifications. Familiarity with laboratory equipment, hazardous materials handling, and digital data entry systems is typically required. Strong observational skills, reliability, and effective communication help ensure accurate reporting and teamwork. These skills are crucial for maintaining safety standards, ensuring product quality, and supporting efficient refinery operations.

What are some common challenges a refinery sampler might face during sample collection, and how can they be addressed?

Refinery Samplers often work in environments where accuracy and safety are paramount. Challenges include handling hazardous materials, working in extreme temperatures, and ensuring samples are not contaminated. To address these, samplers should strictly adhere to safety protocols, use proper personal protective equipment, and follow standardized collection procedures. Regular training and clear communication with the operations and laboratory teams are also key to overcoming these obstacles and ensuring reliable results.

What is the difference between Refinery Sampler vs Petroleum Laboratory Technician?

AspectRefinery SamplerPetroleum Laboratory Technician
CertificationsSampling certifications, safety trainingLab safety, analytical certifications
Work EnvironmentRefinery sites, field samplingLaboratories, testing facilities
Job FocusCollecting samples from refineriesAnalyzing samples in labs
Industry UsageCommon in refining operationsCommon in quality control labs

Refinery Samplers primarily focus on collecting physical samples directly from refinery processes, often working in the field. Petroleum Laboratory Technicians analyze those samples in lab settings, performing tests to ensure quality and compliance. While both roles require safety training and industry-specific certifications, their work environments and daily tasks differ significantly, with samplers working on-site and technicians working in labs.

Job description

About Amphiform:

Amphiform (amphiform.com) is building next-gen energy materials for AI data centres, defence and space: light, abundant and powerful. We achieve that by creating a new type of matter: hybrid materials, built atomic layer by atomic layer, where every atom has a pre-programmed purpose.We just closed a $5.5+1m pre-seed led by General Catalyst and Main Object, with Thomas Wolf (Hugging Face), Charlie Songhurst, and others.


About the role

You'll run the deposition tools and keep the science moving day to day: ALD/MLD runs, sample prep, standard characterisation, and clean, well-recorded data. You'll work alongside our research chemists and report to the Head of Lab Operations. Out Berkeley lab is opening now and we'll have the first reactors installed in ~a month.

What you'll do
  • Operate ALD/MLD reactors for routine deposition runs: execute recipes, run witness wafers, keep the run log
  • Prepare substrates, precursors and samples; handle pyrophoric precursors (TMA, DEZ) and ozone to SOP once trained
  • Run standard characterisation: ellipsometry, XRD, SEM/EDS, BET, electrochemical testing
  • Support synthesis work for the research chemists: simple organic and inorganic prep, solution handling, glovebox work
  • Reduce and plot data (Python or Excel); keep sample tracking and records accurate
  • Maintain calibration, consumables and lab inventory; follow and help refine SOPs and safety protocols
  • Flag anomalies early
What we're looking for
  • Hands-on time in a chemistry, materials or semiconductor lab: glovebox, vacuum tools or cleanroom
  • A degree in chemistry, materials science, chemical engineering, physics or similar. Undergraduate through postdoc all welcome
  • Meticulous, methodical, and genuinely cares about the quality of their work
  • Comfortable with vacuum systems, gas handling and standard lab safety practices
  • Clear written communication
  • Able to work on-site in Berkeley with existing US work authorisation
Nice to have
  • Direct experience with ALD, CVD, sputtering or other vapour-phase deposition
  • Electrochemical testing or fuel cell / electrolyser MEA fabrication
  • Python for data handling and plotting
  • Experience commissioning new equipment from scratch
Not required
  • A PhD
  • Prior ALD experience
  • Fuel cell or catalysis background
