About The Position

Wealthsimple is Canada’s leading financial innovator, offering a comprehensive suite of financial products. The Production Engineering team, within Platform Experience, focuses on enhancing reliability across Wealthsimple’s critical operations. Their goal is to minimize incidents, support safe service deployments, and implement platform-wide improvements. The team measures success by achieving 99.9% uptime on critical flows and ensuring fewer than 1% of weekly active users encounter errors. This new Staff Software Developer role is crucial for bringing senior technical leadership to scale Wealthsimple's reliability. The role involves collaborating across platform and product teams to identify high-impact reliability issues and develop solutions that not only address immediate problems but also elevate engineering standards company-wide. This is a strategic position that shapes how engineering is conducted across the organization.

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

Nice To Haves

• 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

Benefits

• Top-tier health benefits and life insurance
• Long-term group savings with employer match, through Wealthsimple for Business
• 20 vacation days, 4 wellness days, and unlimited sick and mental health days per year
• 90 days away: work outside Canada for up to 90 days per year
• Employee resource groups, including Rainbow (2SLGBTQ), Women of WS, and Black at WS
