Role
Who you are
- You bring a deeply AI-native approach to your work beyond surface familiarity
- You've made agentic coding tools like Claude Code a core part of your development workflow, and you can point to concrete ways they've multiplied your output
- You have strong instincts for which problems AI can automate extremely well (rolling out analytics event wrappers across components, expanding e2e test coverage, scaffolding boilerplate tooling at scale) and you proactively design your systems and workflows to take advantage of that
- You ask first "how could this be automated?" before reaching for the long way around
- Demonstrated experience building developer tooling, test frameworks, or internal platforms. Not just using them; you've designed and owned the systems themselves
- Strong proficiency in TypeScript/JavaScript with hands-on experience in React and/or React Native contexts, particularly building shared libraries, SDKs, or instrumentation rather than product UIs
- Backend development experience (Ruby, Python, Go, or equivalent) and comfort working across APIs, databases, and service-layer code
- A quality engineering mindset. You think about testability, observability, and reliability from the start, not as an afterthought
- An AI-native approach to your craft. You use agentic coding tools as a core part of your workflow, not a novelty, and have a genuine track record of using them to move faster and smarter on the problems they're well-suited for
- Nice to have: experience designing and implementing end-to-end or integration test frameworks across web and mobile
- Nice to have:experience instrumenting frontend SDKs with analytics or observability tooling, or building analytics event pipelines
What the job involves
- As a Senior Software Developer on the CAP OpEx team, you own the application-level quality and tooling layer of our platform
- Where our Site Reliability Engineer owns infrastructure, deployment, and system-level observability, you own the engineering complement: end-to-end test infrastructure, SDK instrumentation, test account tooling, and the internal developer automation that makes CAP engineers faster and more confident
- You build systems that other engineers depend on — not shipping product features to end users, but building the platforms and pipelines that let your colleagues do so safely at scale
- This means thinking in systems, caring deeply about developer experience, and moving fluidly across the full stack: frontend SDKs, backend services, CI/CD. You're comfortable in a TypeScript/React codebase instrumenting an SDK one day and writing a backend script to automate a manual operational workflow the next
- End-to-end testing platform - Architect and own CAP's e2e test suite across web and React Native mobile. This is framework architecture work: runner configuration, CI integration, test standards, and reliability at scale
- SDK observability & instrumentation - Instrument our Account-Opening SDK with standardized analytics events and structured logging, leveraging React hooks and context patterns to give Wealthsimple visibility into frontend onboarding flows
- Test account & staging tooling - Own and evolve CAP's staging and production test account tooling so every team at Wealthsimple can reliably create accurate test accounts for every environment. CAP owns account creation, we should own test account creation too
- Developer automation - Build internal tools and automation that cut manual operational work across the CAP domain: feature flag cleanup, automated triage, AI-powered developer workflows, and whatever the team's highest-leverage opportunities turn out to be
- Quality gates & coverage - Drive shift-left quality practices: mutation testing, code coverage improvements, and CI gates that catch issues before they reach production
- Within 1 month, you'll:
- Learn about the foundations of Wealthsimple, and our current goals for the future that you will start to shape
- Meet other new Wealthsimplers in your onboarding group and key people from each department, to start to build relationships across the company
- Gather an understanding of our technology by pair-programming with your teammates and attending engineering onboarding sessions designed and presented by your peers
- Have an assigned buddy within your team that will assist you in getting up-to-speed with our architecture and current projects
- Within 3 months, you'll:
- Learn Wealthsimple’s technical stack and apply our development patterns and best practices through your work
- Buddy up for your first on-call rotation to help identify and resolve production issues and bugs clients have experienced
- Contribute and support work in a new or existing product and share your work with the team
- Learn how to query our data to measure the impact of your work
- Support over a million clients on their financial journey by shipping your first project or feature in a secure, and scalable way.
- Within 6 months, you'll:
- Reliably ship new features to our clients, following our best practices such as shipping daily, writing automated tests and monitoring
- Contribute to or lead the technical design of a project, while understanding how it will shape our future architecture
- Collaborate with other developers on the team while mentoring and providing continuous feedback via code reviews
- Develop a big picture perspective and understand how our tools and frameworks come together. You’ll feel comfortable contributing to various codebases
- Within 12 months, you'll:
- Lead your first project: planning, scoping and regularly communicating progress to stakeholders to ensure the quality and timelines
- Have provided leverage to our engineering teams by shipping new best practices and tools for all to benefit from
- Have worked closely with our product and design teams, contributing your own feedback and opinions on design and UX
Our take
Wealthsimple is one of a crop of robo-advisors trying to democratise investment management. These companies are disrupting the industry by automating many of the processes involved in investment, removing the need for human advisors.
But while other so-called robo-advisors are focused on courting the high end of the market, Wealthsimple is trying to provide the same types of tools and advice to all users, regardless of the amount they have to invest.
Wealthsimple does have higher fees than some other robo-advisors such as Betterment and Charles Schwab. However, the company believes that it provides a more user-friendly platform, tailored to millennials who will be attracted to Wealthsimple due to its ease of use and social impact offerings.
