We are seeking an Operator to join our energetic, multidisciplinary team at a first-of-its-kind biomanufacturing facility. This position will report to the Director of Fermentation and will follow detailed instructions to operate fermentation and material processing equipment. This is a full-time, on-site position.


Background on the company and position:

The company is led by a technically oriented team – five of our senior team members have PhDs in STEM. We put the safety and well-being of our people above all other priorities. We love to track and measure. We use a software called Asana to monitor project progress and allocate tasks. We follow detailed standard operating procedures for all research testing, plant operations, and business operations. We keep detailed timecards. We have meticulous naming and version control policies for all electronic files. We record and thoroughly analyze all data and are in constant pursuit to find the best and most efficient way to get things done. We work hard and always seek to work smart.


This position will report to the Director of Fermentation and, after initial training, will follow detailed procedures and check lists to operate fermentation and material processing equipment. This is a full-time, on-site position – we are hosted by our partner, a local wastewater treatment plant, and have office trailers near our production site. Odors and noises affiliated with a modern waste processing facility are to be expected.

  • Clearly and carefully record detailed notes and observations
  • Analyze field samples in the lab
  • Perform mathematical calculations
  • Troubleshoot basic challenges
  • Maintain cleanliness at the work site
  • Perform other company-related duties designated at the discretion of the supervisor

  • Organized and attentive to detail
  • Flexible, creative, proactive, punctual
  • A team playerwith strong collaboration skills
  • An excellent communicator
