• Accurately document and report routine production procedures relevant to microbial workflows.

• Associate’s or Bachelor’s degree in Microbiology, Biotechnology, Food Science, or a related field.
• Hands‑on lab experience in microbiology, fermentation, or similar life sciences, with familiarity in aseptic technique and sterile handling.
• Experience preparing and inoculating microbial media (liquid or solid).
• Ability to follow detailed protocols with accuracy and consistency.
• Comfortable working in warm, humid environments typical of SSF setups.
• Reliable, self‑motivated, and able to work independently and collaboratively.
• Competent in basic data recording, spreadsheet entry, and experimental tracking.
• Strong organizational, communication, and time‑management skills.
• Willingness to assist with both experimental work and routine production tasks.

• Experience with spore‑forming bacteria or filamentous fungi.
• Familiarity with 96‑well plate assays or microbial growth quantification techniques.
• Experience using moisture analyzers, pH meters, or fermentation process monitoring tools.
• Previous work in regulated environments (e.g., GMP, CLIA) or startup production settings.
