OverviewXenon 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, team-oriented, inclusive, and productive culture to join the Xenon team.We are advancing an exciting product pipeline to address indications with high unmet medical need, including epilepsy, depression and pain. Our Phase 3 azetukalner program represents the most advanced, clinically validated potassium channel modulator in late-stage clinical development for multiple indications. In March 2026, we announced positive topline data from our Phase 3 X-TOLE2 study of azetukalner in focal onset seizures (FOS), and we anticipate submitting a Current Drug Application to the Food and Drug Administration in the third quarter of 2026. Our Phase 3 epilepsy program also includes a second FOS study, X-TOLE3, which would support regulatory submissions outside the U.S., and the X-ACKT study in primary generalized tonic-clonic seizures, which would support regulatory submissions for an additional epilepsy indication. We also have multiple Phase 3 azetukalner clinical trials underway in major depressive disorder (MDD) and bipolar depression (BPD), based on topline data from our Phase 2 X-NOVA clinical trial. In addition, we are proud of our strong heritage in human genetics, deep understanding of ion channel biology, and expertise in novel chemistries to enable potent, selective ion channel targeting, and continue to advance an early-stage pipeline of novel therapeutic candidates. In 2025, we initiated Phase 1 trials for XEN1701 (targeting Nav1.7) and XEN1120 (targeting Kv7). Nav1.7 and Kv7 are important pain targets, and data from these Phase 1 studies are expected in 2026 to support Phase 2 proof-of-concept studies in acute pain. Backed by a strong balance sheet to support our growth plans, we continue to build a fully integrated, premier neuroscience company with robust discovery, clinical development, corporate, and commercial operations.About The RoleWe are seeking aNetwork Systems Engineer / Senior Network Systems Engineerto join our team.
