On January 11, 2021, we announced our intent to separate our severe genetic disease and oncology businesses into differentiated and independent publicly traded companies. We will retain focus on severe genetic disease (SGD) and will launch our oncology business (“Oncology Newco”) as a new entity, with the completed transition expected by the end of 2021.



At bluebird, only two things matter - patients and our people. When you join the nest, you're not just landing a new gig, you become a part of a flock that's soaring to new heights. We’re 1100+ doers, thinkers and collaborators across the globe with a strong sense of our values and our purpose. Our innovation and sustainability are rooted in the diversity of our teams and results are achieved through cooperation and the incorporation of multiple points of view. This is personal and we approach every challenge with radical care. The time is now to rise up and recode the science, the systems, and the status quo.


bluebird bio’s Oncology Research team is composed of collaborative, intelligent, and passionate individuals driven to grow our cellular immunotherapy programs, singularly focused on delivering transformative medicine to patients. The Oncology Research team is seeking a highly motivated Senior Scientist to support pre-clinical research engineering CAR-T/TCR molecules. If you crave innovation, embrace new challenges, and strive to solve tough problems, come join us!


We are a team that works, learns, and grows together - and we're eager to start co-creating with you! As a Senior Scientist, you will play a key role leading the discovery and optimization of early product concepts by:

  • Leading a team responsible for iterating, optimizing, and implementing a high-throughput CAR/TCR screening platform to enable the selection of top constructs from libraries of potential variants
  • Designing complex libraries combining various CAR/TCR technologies to tune T-cell activity in response to various stimuli
  • Designing and executing studies that provide the scientific basis for making data-driven decisions
  • Running established assays (e.g., co-cultures to evaluate antigen-dependent cytokine release, target cell cytotoxicity, and T cell proliferation)
  • Collaborating productively and creatively with other scientists to develop novel CAR architectural designs.
  • Developing assays to improve in vitro to in vivo correlation and discriminate between highly similar variants
  • Identifying creative combinations to overcome tumor microenvironment suppression of CAR-T cell efficacy.
  • Analyzing, interpreting, and presenting data at working groups and departmental seminars, with opportunities to present work at national conferences
  • Contributing to new technology assessment, in-sourcing, and implementation
  • Representing the Oncology Research team in a variety of cross-functional forums to provide feedback on scientific strategy, experimental priorities, and timelines


You’re the bird we’re looking for if you have:

  • PhD in immunology, molecular biology or related discipline with 5+ years’ industry experience, or MS degree with 10+ years of industry experience, or BS degree with 15+ years of industry experience.
  • Experience mentoring junior scientists and leading focused project teams.
  • Expertise in concepts of protein engineering including library design, construction, and screening. Prior antibody experience is a plus.
  • Expertise in high-throughput screening.
  • Expertise in mammalian cell culture, such as tumor cell lines and primary human cells.
  • Expertise in standard immunological assays (flow cytometry, MSD/Luminex).
  • Expertise in basic molecular biology techniques (cloning, cell line engineering). Familiarity with CRISPR-Cas9 gene editing, a plus.
  • Expertise in genomic analysis, including RNA-seq, scRNA-seq, Nanostring, a plus.
  • Excellent problem-solving ability to troubleshoot complex technical and scientific problems.
  • Must thrive in an innovative, fast-paced environment where flexibility, resourcefulness, and resilience are key to rapid information processing and change-management
  • Excellent communication and interpersonal skills, natural ability to constructively raise issues and crowdsource solutions, willingness to foster relationships with colleagues and stakeholders

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?
