About the Build Platform Team

At Wealthsimple, the Build Platform team is on a mission to make developing great software fast, intuitive, and enjoyable. We believe engineers should focus on building incredible features for our clients, not fighting their environment. Our job is to clear the path. We do this by treating our platform as a product. Our internal developers are our customers, and their success is our primary measure of impact.

As a Developer on our team, you won't just be building tools; you'll be shaping the entire developer journey at Wealthsimple. From their first day onboarding to their thousandth code submission, you'll be making the experience seamless. You will support a diverse engineering organization that uses Ruby, Python, Kotlin, and TypeScript to build the future of finance. Your work will directly empower hundreds of developers to ship high-quality, secure code to millions of users with confidence and speed.

• Pioneer new ways to improve developer productivity by leveraging emerging technologies like AI to optimize workflows, improve test coverage and reduce friction in the development lifecycle.
• Shape the next generation of our development environments. A key focus will be on rolling out and enhancing containerized development environments across hundreds of services to drastically reduce setup time, eliminate "works on my machine" issues, and create a consistent, powerful local development experience for all engineers.
• Modernize core internal libraries and tooling. This includes improving our command-line interface to automate developer machine setup, sunsetting legacy tools in favor of safer, auditable alternatives, and evolving the shared libraries that underpin our microservices architecture.
• Define and measure operational excellence at scale. You'll help build automated scorecards that give every team clear, actionable insights into the health of their services, covering everything from dependency management to monitoring and scalability.
• Elevate our testing infrastructure. You'll get to evolve how our teams test complex systems, such as by building robust backend mocking solutions to increase end-to-end test stability and by enabling isolated testing of asynchronous, event-driven workflows in ephemeral environments.
• Champion engineering best practices by partnering with teams across Wealthsimple to deliver platform improvements that increase their velocity and confidence.

• 7+ years of experience in software development as part of a team, preferably a platform-oriented team.

• Experience designing, building, and maintaining internal libraries, frameworks, or tooling used by other engineering teams.
• A forward-thinking mindset and a passion for applying modern technology. You're naturally curious about the latest industry trends and are always exploring how they can be used to create a best-in-class development experience.
