Scientist II at 4D Molecular Therapeutics

Attention recruitment agencies: All agency inquiries are vetted through 4DMT’s internal Talent Acquisition team. No unsolicited resumes will be accepted. The 4DMT Talent Acquisition team must expressly engage agencies on any requisition. Agencies contacting hiring managers directly will not be tolerated, and doing so may impact your ability to work with 4DMT in the future.

 

4DMT is a clinical-stage biotherapeutics company harnessing the power of directed evolution for targeted genetic medicines. We seek to unlock the full potential of gene therapy using our platform, Therapeutic Vector Evolution (TVE), which combines the power of directed evolution with our approximately one billion synthetic AAV capsid-derived sequences to invent evolved vectors for use in our products. We believe key features of our targeted and evolved vectors will help us create targeted product candidates with improved therapeutic profiles. These profiles will allow us to treat a broad range of large market diseases, unlike most current genetic medicines that generally focus on rare or small market diseases.  

Company Differentiators: 

•    Fully integrated clinical-phase company with internal manufacturing
•    Demonstrated ability to move rapidly from idea to IND
•    Five candidate products in the clinic and two declared pre-clinical programs
•    Robust technology and IP foundation, including our TVE and manufacturing platforms
•    Initial product safety and efficacy data substantiates the value of our platforms
•    Opportunities to expand to other indications and modalities within genetic medicine

GENERAL SUMMARY: 

As a Scientist II on the Payload Innovation team, you will contribute to the development and discovery of novel Therapeutic Payload elements and the evaluation of these Payload Constructs through payload elements database construction, candidate screening and novel assay development. You will work closely with the Emerging Technology and Early Product development teams to ensure that the novel payload construct meets the product development requirements. Reporting to a Director in the Payload Innovation team, you will execute bioinformatics pipelines to identify potential payload construct candidates and conduct laboratory experiments to screen these candidates and propose lead candidates for downstream product development. Secondary to these responsibilities, you will develop different NGS and other molecular biology assays for payload construct evaluation.
