Scientist

ROLE SUMMARY

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

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

Screening Considerations / Red Flags

• Lack of communication skills or difficulty working in team environments

• Limited or no hands-on bioreactor experience (for experienced candidates)

• Lack of aseptic technique experience

Interview Process

• 1 onsite interview

• Includes 3 x 30-minute sessions with team members

• Typically 4–5 candidates interviewed per role
