About this opportunity

Make your mark for patients

The Gene Therapy Vector Core group is seeking a Scientist II in Upstream Process Development and Bioprocess Analytics team to support genetic medicine projects and AAV gene therapy platform development.

Additional responsibilities include supporting routine testing for characterization of research grade materials and for guiding process development activities.

Responsibilities:

Leading the development and execution of custom molecular assays including ddPCR and qPCR to support gene therapy analytics

Optimizing and applying cutting-edge next generation sequencing (NGS) technologies to characterize impurities and assess heterogeneity in AAV drug products

Utilizing strong biology foundations to help guide or run cell-based potency assays to evaluate biological function and activity

Support gene therapy platform development through the application of evolving analytical methodologies and cross-team collaborations  including capsid engineering

Function independently and cross functionally across various UCB teams (data scientists, cell biologists, disease area experts, CMC professionals, etc.)

Ability to manage priorities, engage/communicate in a multidisciplinary environment, and provide exemplary documentation of experimental work

Required Education, Skills and Experience:

MS degree in Molecular Biology, or related field, with over 10 years of experience – OR – PhD or Post Doc with 2+ years of experience.

4+ years expertise in PCR based assay development and molecular characterization of AAVs or biomolecular characterization for gene therapies

4+ years of NGS (long and/or short read technology) development experience (genomic DNA, targeted amplicon, small RNA, and RNA-seq) to enable genomic and transcriptomic analyses for early drug discovery and drug substance analytics

4+ years of experience serving as a functional representative in multi-disciplinary drug discovery project teams

Preferred Education, Skills and Experience:

PhD in Molecular Biology, Biochemistry, or related field with direct AAV characterization experience supporting molecular analytics of AAV vectors

6+ years of experience in molecular analytical characterization of AAV vectors

6+ years of hands-on experience with NGS library preparation, Illumina and PacBio data acquisition and QC to support drug discovery activities

At least 6 years of experience in drug discovery or development in a pre-clinical setting with a focus on molecular characterization, analytical method development, characterizing impurities and identifying biological complexities.

Serve as the primary owner of developing, optimizing, and/or routinely conducting cell based potency assays to evaluate biological function and activity

Salary:

This position’s reasonably anticipated base salary range is $99,200 to $130,200 per year. The actual salary offered will consider internal equity and may also vary depending on the candidate’s region, job-related knowledge, skills and experience, among other factors.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
