ABOUT THE OBSERVABILITY PLATFORM TEAM The Observability Platform team exists to make production legible to every engineer and AI agent at Wealthsimple, on their first day and every day after. We treat the platform as a product, with our internal engineering teams as our customers. Our mission is to provide the best, most consistent logging, metrics, and tracing experience. We do this by brokering tools and patterns into golden paths that accelerate best practices, and by connecting teams to business impact through SLOs, user flows, and customer experience signals. We instrument on open standards so that switching costs are a configuration change rather than a rewrite, we optimize for the questions engineers did not anticipate rather than for pre-built dashboards, and we design for a world where both humans and AI agents investigate production through fast, high-cardinality data. As the Staff Software Engineer on this team, you are the deepest technical builder and the person who sets the technical bar. You design the foundations, write the code that matters most, and raise the engineering quality of everyone around you. IN THIS ROLE YOU'LL HAVE THE OPPORTUNITY TO: - Design and build the events-first foundation. Own the architecture of the wide-event data mode
