The Team

The Alloy Genetic Medicines group is innovating a novel RNA-based drug discovery platform, namely ?AntiClastic?, spanning the fields of antisense therapeutics to immunomodulating therapeutics. This technology platform was launched by Alloy in 2023 after exclusively licensing its underlying intellectual property which implements a novel spatial conformation of the oligonucleotide developed by Sudhir Agrawal of Arnay Sciences. The team works closely with external partners to discover and develop AntiClastic RNA medicines.

The Role

Alloy Therapeutics is seeking a visionary and technical leader to serve as the subject matter expert for Bioconjugation and Delivery within our Genetic Medicines Unit. Whether you are a seasoned manager or an elite independent contributor, you will play a pivotal role in bridging the gap between innovative nucleic acid chemistry and transformative therapeutic delivery.

You will be responsible for the end-to-end development, documentation, and implementation of process and analytical pipelines for Antibody Oligonucleotide Conjugates (AOCs) and targeted Lipid Nanoparticles (LNPs). This role requires a rare blend of deep technical mastery in conjugation chemistry and a strategic understanding of Quality by Design (QbD) to drive our internal programs and external partnerships forward.

Principal Responsibilities

• Process Leadership: Design and execute robust bioconjugation pipelines for AOCs (utilizing ASOs, siRNA) and targeted LNPs. This includes conjugating oligonucleotides, lipids, and nanoparticles to various targeting domains such as peptides, proteins, and aptamers.
• Innovation: drive innovation to improve circulating half-life, tissue penetration, cellular uptake, and intracellular bioavailability of payloads
• Method Development & Analytics: Establish high-resolution analytical methods and pipelines. You will be directly responsible for developing and proceduralizing in-process testing and finished product QC using HPLC (SEC, IEX, IPRP) and LC-MS.
• QbD & Documentation: Operate withing Quality by Design (QbD) framework, maintaining meticulous records in our Electronic Lab Notebook (ELN). You will iterate between product descriptions and process knowledge to ensure scalable, high-quality manufacturing.
• Supply Chain & Quality: Lead the review of raw materials and their quality attributes. Define process descriptions and manage technologies required for successful process scale-up.
• Cross-Functional Collaboration: Act as a central pillar within Genetic Medicines and Alloy, collaborating seamlessly with the Nucleic Acid Chemistry and Biology groups will be essential. You will serve as a primary technical point of contact for external partners.
