• Hands-on experience with LCMS or mycotoxin testing, or a strong interest in cross-training in these methods.
• Familiarity with ISO, GMP, or GLP requirements and documentation practices.
• Strong problem-solving skills and a methodical approach to root cause analysis and nonconformance investigations.
• Effective communication skills for documenting results, collaborating with colleagues, and supporting training activities.
• Ability to contribute to SOP development and continuous improvement initiatives.
• Service-oriented mindset with a focus on meeting customer turnaround times and demonstrating the value of a growing laboratory.
• Team-oriented attitude, willing to support colleagues and share responsibilities in a small, collaborative group.

Work Environment

This role is based in a small molecular laboratory located within a corporate headquarters. The lab is equipped with newer instrumentation and offers the opportunity to work on a variety of projects as the operation grows. The team is small, with a close-knit, family feel where colleagues support one another and collaborate to complete testing. You will interact with other personnel onsite but work most closely with laboratory staff and scientists.

The work involves handling ground grain and food samples, so the environment can be dusty at times. Noise levels vary depending on activities; grinding equipment can make the lab loud, while other times it may be quiet. Wearing headphones or earbuds is permitted when the lab is loud, provided you remain able to communicate effectively with the team.

The facility is pet-friendly, and there may be dogs or cats present in office areas, though animals are not allowed inside the laboratory itself. Standard laboratory attire and safety practices apply within the lab.

Typical hours fall within an 8:00 a.m. to 5:00 p.m. or 10:00 a.m. to 7:00 p.m. window, Monday through Friday, with flexibility required based on sample flow and customer turnaround times. Overtime may occasionally be needed but is expected to be limited, with an emphasis on flexibility rather than consistently late hours. The culture is collaborative, team-oriented, and service-focused, with an emphasis on building a strong reputation for the new lab and supporting one another to meet testing and quality goals. Contract employment includes holiday pay and offers the potential for transition to a full-time role as the lab continues to grow.

This is a Contract to Hire position based out of Saint Charles, MO.

The pay range for this position is $28.00 - $32.00/hr.

Individual compensation offered for this position within this range will depend on many factors, including qualifications, skills, relevant experience, job knowledge, geographic location, internal equity, and other pertinent job-related factors.

Eligibility requirements apply to some benefits and may depend on your job classification and length of employment. Benefits are subject to change and may be subject to specific elections, plan, or program terms. If eligible, the benefits available for this temporary role may include the following: • Medical, dental & vision • Critical Illness, Accident, and Hospital • 401(k) Retirement Plan – Pre-tax and Roth post-tax contributions available • Life Insurance (Voluntary Life & AD&D for the employee and dependents) • Short and long-term disability • Health Spending Account (HSA) • Transportation benefits • Employee Assistance Program • Time Off/Leave (PTO, Vacation or Sick Leave)
