About the Role

We are seeking a highly motivated Co-op to support early-stage discovery efforts within our Peripheral Artery Disease (PAD) program, a newly initiated therapeutic discovery program focused on achieving proof-of-concept (POC) by the end of the year. This position will provide hands‑on experimental support for routine but mission‑critical discovery and molecular biologyactivities that enable efficient advancement of the program. The role offers meaningful exposure to foundational discovery workflows within a fast‑paced, research‑focused environment, with opportunities to contribute across additional programs as bandwidth allows.

This position is a unique joint effort between the Discovery and Molecular Biology teams, with opportunities to support cloning projects focused on antibody expression, contribute to high‑throughput cloning pipelines, and gain exposure to laboratory automation.

Key Responsibilities:

The Co‑op’s core responsibilities will focus on executing routine, mission‑critical discovery and molecular biologyexperiments that support target validation, hit identification, and early characterization within the PAD program. The role will involve hands‑on laboratory work using established protocols, with opportunities to contribute to:

• Molecular biology techniques supporting library preparation, cloning, and hit screening
• Antibody selection methodologies, including phage display–based biopanning on PAD‑relevant targets
• ELISA‑based screening and other binding and characterization assays
