Bachelor’s degree in Biology, Bioengineering, Molecular Biology, or a related scientific discipline with 1-3 years of hands-on experience in Cell Line Development.
Mastery of aseptic cell culture technique, experience with suspension cell lines, and proficiency with CLD lab equipment.
Hands-on experience operating automated micro-bioreactor systems (e.g., ambr® 15 / ambr® 250) or benchtop glass/disposable bioreactors (3L–10L).
Proven capability to execute lab protocols independently, manage daily tasks, and analyze data with high attention to detail.
Meticulous record-keeping, strong communication skills, and a collaborative team-first mindset.

Responsibilities

Independently execute mammalian cell culture workflows using strict aseptic technique within a biosafety cabinet (BSC).
Safely operate and maintain analytical suites, including Vi-CELL analyzers, NOVA analyzers, centrifuges, incubators, and liquid handlers.
Manage liquid nitrogen vial storage, inventory documentation, media preparation, and consumable supplies for the CLD laboratory.
Conduct routine experiments, analyze data to verify quality standards, troubleshoot minor technical issues, and maintain accurate Standard Operating Procedures (SOPs) and lab records.
Assist with upstream high-throughput micro-bioreactors or benchtop vessels to support scale-up and process optimization.
Be a good team player, partnering effectively with scientists and cross-functional teams to meet production timelines.
