ROLE:  Research Assistant – Immunology, R&D 

Within its Preclinical Department, iTeos is looking for a highly motivated and skilled Research Assistant. The successful candidate will help develop breakthrough cancer immunotherapies through laboratory work, supporting the validation of new IO targets but also the discovery of small molecules and biologics for the development of innovative cancer immunotherapies. In this role, the candidate will work independently and as part of a team to generate robust in vitro/ex vivo data packages, helping to guide decision making and timely progression to development and clinical trials. The lab is equipped with state-of-the art technologies to study both in vitro and in vivo experimental models of immunology and cancer. 


  • Design, validate and perform experimental in vitro and ex vivo immunoassays on human and mouse samples, using Standard Operating Procedures.  Time keeping in the lab is evaluated around 80%.
  • Characterize immune responses ex vivo and in vitro by designing FACS panels, performing flow cytometry and analyzing cytokines/chemokines secretion by ELISA/MSD/Luminex/CBA.
  • Perform in vitro cell culture assays and maintain tumor cell lines.

  • Master degree in Life Sciences, Immunology, Pharmacology, Biochemistry, or closely related field.
  • Hands-on experience in setting-up human or mouse immune cell-based assays (isolation, handling of primary immune cells) and multicolor flow cytometry is highly desirable.
  • Additional cell culture and molecular cell biology techniques are important assets (ELISA, qPCR, experience with MSD or Luminex platform, gene expression analysis).   
  • Previous experience in the biotech/pharma industry or in a similar academic position is an advantage.
  • Knowledge of Microsoft Office. Knowledge of Prism is a plus.
  • Knowledge of cytometry software such as Diva and FlowJo is a plus.
  • Good command of English (oral and written).
