Scientist

Title- Bench Scientist - II

Location- Andover, MA

Duration- 12-month contract (potential to extend)

Position Overview

• We are seeking two highly motivated scientists to support the upstream mammalian process development in a laboratory environment.
• This role focuses on hands-on bioreactor operations, mammalian cell culture, and experimental execution to support biologics development (e.g., monoclonal, bispecific, and Tri specific antibodies).
• This is a lab-intensive role requiring strong technical expertise, collaboration skills, and the ability to communicate experimental findings effectively.

Key Responsibilities

• Perform hands-on mammalian cell culture using bioreactors (CHO systems)
• Set up, operate, and monitor bench-scale bioreactors
• Design, execute, and analyze experiments
• Maintain accurate lab documentation (lab notebooks, batch records)
• Analyze cell culture performance (cell density, metabolites, nutrients)
• Write experimental plans and technical reports
• Collaborate cross-functionally with upstream (bacterial), downstream, and analytical teams
• Order lab supplies and maintain inventory
• Participate in weekend/on-call rotation as needed

Work Environment

• ~70% lab work / 30% desk-based work
• Primarily in one building, with occasional movement across campus for sample handling
• Team size: ~10 scientists (multiple levels from lab tech to principal scientist)

Required Qualifications (Must-Haves)

• Bachelor’s degree in biology, Biochemistry, Chemistry, Bioengineering, or related scientific field
• Minimum 3 years of relevant lab experience (industry preferred; strong academic experience considered)
• Hands-on experience with mammalian cell culture (CHO cells)
• Experience operating bench-scale bioreactors
• Strong aseptic technique experience (required)
• Experience designing and executing experiments independently
• Ability to document work and write technical reports
• Strong communication and teamwork skills

Preferred Qualifications (Nice-to-Haves):

• Experience with perfusion systems (continuous culture)
• Familiarity with bioreactor control systems (e.g., SCADA, DeltaV)
• Experience with electronic lab notebooks (ELN) or LIMS
• Exposure to analytical tools for cell culture monitoring
• Familiarity with statistical analysis software

Additional Details:

• No travel required

• Weekend rotation: approximately 1 weekend per month

o Typically 3–4 hours/day (Saturday & Sunday)

o Paid as overtime

• Candidates must be comfortable working in a highly collaborative lab environment

Success Profile:

The ideal candidate is:

• Hands-on and technically strong in the lab

• A clear communicator who can share results effectively across teams

• Able to work independently with minimal supervision

• Collaborative and team-oriented

Interview Process

• 1 onsite interview
• Includes 3 x 30-minute sessions with team members
