About this opportunity

Job Description

General Summary

The DMD Biology team at Vertex Cell and Genetics Therapy Research (VCGT Research) is seeking a highly experienced and motivated Principal Research Associate to build genetic therapy candidates and to develop and execute assays to support advancing non-viral therapeutics through program stage gates. The successful candidate will bring strong hands-on expertise in molecular biology, cell biology, gene-expression analysis, and protein-based assays. This individual will work closely with cross-functional partners to generate high-quality data that informs discovery-stage decisions and candidate progression. This laboratory-based role will design, execute, optimize, and interpret molecular and cellular assays that characterize functional delivery, intracellular activity, gene expression, and immunological and pharmacological responses.

Key Responsibilities

Build gene expression constructs using advanced molecular biology tools.

Design, execute, and optimize in vitro assays supporting non-viral delivery biology and gene replacement strategies for Duchene Muscular Dystrophy.

Develop and apply cellular and molecular biology workflows to evaluate uptake, dose response, intracellular trafficking, functional delivery, gene expression, and pharmacological activity of therapeutic candidates for Duchene Muscular Dystrophy.

Perform nucleic acid extraction and downstream gene-expression analyses, including qPCR, RT-qPCR, NGS library construction, and related molecular characterization methods.

Execute protein and cellular assays, including but not limited to ELISA, MSD, Western blotting/Jess, immunoprecipitation, reporter gene assays, and cell-signaling assays to assess cellular responses and delivery outcomes.

Support both in vitro and in vivo evaluation of gene-editing and gene-replacement approaches using relevant molecular and cellular readouts.

Collaborate closely with cross-functional teams and external partners to design studies, communicate findings, and advance program priorities.

Prepare clear experimental and technical summaries, data reports, and presentations; proactively communicate findings.

Maintain accurate, timely, and well-organized electronic laboratory notebook records and structured documentation/SOPs.

Knowledge and Skills:

Significant hands-on laboratory experience in molecular cloning, molecular biology assays, cell biology assays, protein-based assays, and mammalian cell culture.

Experience with: RNA/DNA extractions, qPCR, plasmid construct design, gene expression analysis, reporter assays, Western Blot/Jess, MSD, immunoprecipitation, ELISA etc.

Experience with one or more of the following: RNA/DNA therapeutics, Lipid nanoparticle (LNP) dosing, receptor biology and intracellular trafficking, gene expression, cell transfection/transduction experiments, or confocal imaging.

Strong collaboration skills, with the ability to work in a highly cross functional, fast-paced research environment.

Strong written and verbal communication skills, including the ability to summarize complex experimental findings clearly.

Experience with one or more of the following: IND-enabling studies, data visualization, report writing, electronic lab notebook keeping (e.g. Benchling), or structured data documentation.

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.
