You will:

• Operate and develop methods on parallel flash chromatography systems (Interchim PuriFlash XS520Plus / ClearPeak) — column packing, gradient development, fraction pooling
• Run wiped-film and short-path distillation; troubleshoot vacuum and thermal systems
• Execute kg-scale crystallization and recrystallization (CBG, CBD, CBC)
• Handle Class I flammable solvents (pentane, heptane, IPA) safely and within permitted quantities
• Author and maintain SOPs and batch records under our 21 CFR Part 111-aligned Quality Manual
• Review third-party COAs, manage retains, and drive corrective action on out-of-spec lots

You have:

• B.S. in Chemistry, Chemical Engineering, or Biochemistry — or equivalent hands-on process experience
• 3+ years in a production or pilot-scale lab (pharma, nutraceutical, food ingredient, flavor/fragrance, or cannabis all count)
• Real preparative chromatography and distillation experience — not just coursework
• Documentation discipline. If it isn't written down, it didn't happen.

Nice to have: natural product isolation, GMP/dietary supplement environment, C1D1 / flammable-storage familiarity, cannabinoid chemistry.

Why here: Small team, no bureaucracy, you own your process end to end. Modern equipment already installed. Direct line to the owner.

Apply with a resume and one paragraph: describe a purification or distillation problem you solved and how you knew it worked.
