Wealthsimple Technologies - Staff Software Developer, Production Engineering
Requirements
• 8+ years of software engineering experience, with significant time in platform, infrastructure, or SRE work • Demonstrated track record of improving reliability at scale — reducing incidents, building guardrails, or driving operational standards across multiple teams • Strong proficiency in backend systems and distributed architecture; you can diagnose complex failure modes across a service mesh • Experience with load testing and capacity planning, and the ability to translate findings into concrete engineering improvements • Proven ability to work across engineering teams as a technical influencer — driving adoption of standards and practices without direct authority • Familiarity with Kubernetes, Helm, Argo and modern deployment tooling • Strong written and verbal communication — comfortable presenting findings and recommendations to both engineering teams and senior leadership • You think in systems — you’re not looking for the fix, you’re looking for what caused the problem and how to make sure it doesn’t happen elsewhere • You’re comfortable working without direct authority; you build credibility through the quality of your thinking and the clarity of your recommendations • You hold a high bar for operational excellence without making it someone else’s problem to catch up to — you bring people along • You’re energised by ambiguity, not slowed down by it; you know how to prioritise when everything feels urgent • You’re curious about where AI-assisted tooling is headed in reliability engineering, and you want to help shape how we use it — not just observe it from a distance
Responsibilities
• Improve the platform to prevent incidents — designing and driving adoption of guardrails, sensible defaults, and engineering standards that reduce the likelihood of failures across services • Build tooling that reduces time to mitigation when incidents occur, including contributing to our in-house product on AI-assisted incident response • Own the investigation and follow-through on load test findings — translating results into concrete reliability improvements across critical flows • Work across platform and product engineering teams as a technical influencer — participating in architecture and readiness reviews, coaching service owners, and driving adoption of scalable reliability practices • Identify recurring failure patterns and design platform-level fixes that prevent them from showing up again in a different service • Contribute to the team’s reliability syncs with product engineering, helping align on incident themes, critical-flow risks, and the next highest-leverage initiatives
