Senior Developer on Wealthsimple’s Delivery Platform team enhancing CI/CD infrastructure and deployment tools. Supporting diverse engineering teams to deliver high-quality financial software efficiently.
Responsibilities
Evolve progressive delivery with Argo Rollouts and GitOps. Enhance our canary deployment strategies, improve automated health checks and rollback triggers, and build self-service deployment tools that give engineering teams the power to ship safely and independently.
Optimize CI/CD infrastructure at scale. Improve our CI workflows to optimize for speed and reliability, optimize build times across hundreds of services, enhance artifact management and package publishing workflows, and build tools that make continuous integration faster and more dependable.
Build deployment gates and guardrails that prevent production incidents. Design and implement automated quality checks including end-to-end testing, load testing, and progressive delivery validations that catch issues before they reach production. You'll be responsible for ensuring every deployment is safe and reversible.
Build world-class deployment observability and visibility. Create comprehensive deployment monitoring, dashboards, and alerting through Datadog and custom tooling. Integrate deployment metrics into Backstage to give every engineer real-time insights into their service's deployment health, success rates, and performance characteristics.
Drive Wealthsimple's 2026 reliability mission. Reliability is our top priority this year, and you'll be at the center of building systems that make it a reality. Implement chaos testing frameworks to validate system resilience, build automated rollback mechanisms, and create deployment confidence metrics that teams can trust.
Pioneer continuous, automated load testing. Design and build infrastructure that continuously validates performance characteristics of services before and during deployments. Implement k6-based testing frameworks, automated performance regression detection, and integration with deployment gates to catch performance issues early.
Champion engineering excellence and mentorship. Partner with teams across Wealthsimple to understand their deployment pain points and build solutions that increase their velocity. Share your expertise through documentation, training sessions, and code reviews. Mentor mid-level engineers on the team and across the organization.
