Senior Medical Science Liaison (Great Lakes)

Who We Are:


Xenon Pharmaceuticals (NASDAQ:XENE) is a neuroscience-focused biopharmaceutical company dedicated to drug discovery, clinical development, and commercialization of life-changing therapeutics for patients in need. We are looking for great people who thrive in a respectful, collaborative, inclusive, and productive culture to join the Xenon team.


What We Do:


We are advancing an exciting product pipeline to address indications with high unmet medical need, including epilepsy and depression. Our flagship azetukalner program represents the most advanced, clinically validated potassium channel modulator in late-stage clinical development for multiple indications. Building upon the positive results and compelling data from our Phase 2b “X-TOLE” study in adult patients with focal epilepsy, our Phase 3 epilepsy program includes multiple clinical trials evaluating azetukalner in patients with focal onset seizures and primary generalized tonic-clonic seizures. In August 2025, we announced the completement of patient recruitment in our Phase 3 X-TOLE2 study and topline data are anticipated in early 2026. We also have multiple Phase 3 azetukalner clinical trials in major depressive disorder (MDD) and bipolar depression (BPD) underway, based on topline data from our Phase 2 “X-NOVA” clinical trial. In addition, we are proud of the leading-edge science coming out of our discovery labs, including early-stage research programs that leverage our extensive ion channel expertise and drug discovery capabilities to identify validated drug targets and develop new product candidates, and have recently initiated Phase 1 studies for our follow-on Kv7 channel opener, XEN1120, and our lead Nav1.7 development candidate, XEN1701, in pain. Backed by a strong balance sheet to support our growth plans, we continue to build a fully integrated, premier neuroscience company with strong discovery, clinical development, corporate, and commercial operations.
