  • Maintain various logbooks and documentation in accordance with Standard Operating Procedures (SOPs).  
  • Support the training and onboarding of new team members to ensure their competency and compliance with laboratory procedures.  
  • Communicate effectively across departments—including Quality Assurance, Client Care, and other internal teams—to ensure smooth workflow and alignment with company objectives.

Who You Are 

  • Bachelor’s degree in Biology, Microbiology, or a related field, or equivalent relevant experience.
  • Preferred experience in sterility testing and cleanroom operations; experience in cGLP and/or cGMP regulated laboratory environments is a plus.

  • Proficiency in laboratory data entry and laboratory information or data management systems.
  • Excellent attention to detail, strong organizational skills, and the ability to maintain accurate documentation in compliance with company policies, SOPs, and safety regulations.
  • Ability to manage time effectively, maintain focus, meet established timelines, and adapt to new processes and skills as required.
  • Ability to work independently with minimal supervision as well as collaboratively in a team environment, following instructions accurately and communicating effectively across disciplines.
  • Ability to execute tasks in a cleanroom environment; head-to-toe PPE (including full bunny suit) is required at all times.
  • Ability to stand for extended periods while conducting testing procedures, with the physical dexterity to perform testing accurately and precisely.
  • Frequent use of laboratory equipment and routine exposure to chemicals in a controlled, regulated setting.
