ABOUT eGENESIS

eGenesis is a clinical-stage biotechnology company developing human-compatible engineered organs to address the severe global organ shortage. The Company’s proprietary genome engineering platform enables extensive, multiplex gene edits to remove key biological barriers, add protective human transgenes, and inactivate endogenous retroviruses. EGEN-2784, a genetically engineered porcine kidney, is the Company’s lead program and is currently being evaluated in a multi-patient Expanded Access study at MGH. eGenesis is headquartered in Cambridge, MA.
At eGenesis, our core values—innovation, collaboration, compassion, resilience, and passion—are at the center of how we work. We engineer hope and bring passion to everything we do. We collaborate and learn from one another, combining diverse expertise to tackle complex challenges. We innovate boldly, pushing boundaries and science to new heights. where no pig organ has gone before. With resilience, we navigate challenges and celebrate progress together. And in all we do, we lead with compassion—for our patients, our people, and our pigs.

POSITION SUMMARY

We are seeking a highly motivated Principal Research Associate to join the Analytical Development team. This is an opportunity to develop analytical methods supporting gene-edited xenotransplantation products in a dynamic environment focused on molecular and cellular engineering.

In this role, you will independently develop analytical assays from initial concept and feasibility through optimization, qualification, and transfer. Responsibilities include assessing transgene expression and biological function in genetically modified porcine cells, with a particular emphasis on developing robust, mechanism-relevant potency assays. The successful candidate will be expected to select appropriate assay formats and biological readouts, establish controls, understand critical assay variables, and solve complex development challenges with limited supervision.

The position involves significant hands-on cell culture, including the isolation, growth, and maintenance of porcine primary cells. Methods may include cell-based functional assays, flow cytometry, ELISA, and real-time PCR. This is a full-time, laboratory-based position suited for a proactive, rigorous, collaborative scientist who is comfortable building new methods where established procedures may not yet exist.

    PRIMARY RESPONSIBILITIES

  • Independently develop expression and potency assays from the ground up, from assay concept and biological rationale through feasibility, optimization, and qualification.
  • Serve as the subject matter expert for assigned methods and define assay strategy, format, biological readout, controls, and system-suitability criteria.
  • Develop and optimize fit-for-purpose methods for transgene expression and product characterization, including flow cytometry, ELISA, real-time PCR, and cellular assays.
  • Evaluate assay performance, including precision, specificity, sensitivity, relative accuracy, range, robustness, and repeatability, as appropriate to the method and stage of development.
  • Independently troubleshoot assay failures, conduct root-cause investigations, interpret complex data, and recommend scientifically justified paths forward.
  • Culture, isolate, expand, characterize, and maintain mammalian primary cells and cell lines while controlling sources of biological variability.
  • Manage critical reagent and reference-material lifecycles, including cell banks, standards, antibodies, controls, inventory, and lot-bridging studies.
  • Partner with QC and cross-functional stakeholders on method transfer, assay alignment, and transfer-related troubleshooting.
  • Author and review development and qualification documents, maintain accurate laboratory records, communicate results and risks, and provide technical guidance to junior team members.

    BASIC QUALIFICATIONS

  • B.S. or B.A. in cell biology, immunology, biomedical engineering, or a related scientific discipline with 6-8 years of relevant industry experience, or an M.S. with 4-6 years of relevant industry experience.
  • Demonstrated experience independently developing analytical methods from initial concept and feasibility through optimization, qualification, and implementation.
  • Hands-on experience developing, optimizing, and troubleshooting assays that measure biological activity or potency.
  • Expertise in mammalian cell culture and assay development using flow cytometry and ELISA, including control strategy and troubleshooting.
  • Experience designing controlled experiments, interpreting multivariable data, evaluating assay performance, and establishing fit-for-purpose controls and acceptance criteria.
  • Ability to independently manage laboratory work across concurrent projects, document and communicate scientific results clearly, and collaborate effectively across functions.

    PREFERRED QUALIFICATIONS

  • Direct experience developing cell-based potency assays, particularly with engineered primary cells, endothelial cells, immune-mediated mechanisms, or complex functional readouts.
  • Experience with analytical method qualification and transfer to a QC or regulated testing environment.
  • Experience establishing and monitoring critical reagent or cell-bank controls, including lot qualification and bridging studies.
  • Experience providing technical mentorship or guidance to research associates or junior scientists.
