About the Team

Join the team responsible for defining the gold standard of financial onboarding in Canada. We are not just building forms; we are transforming a classically painful experience, opening a bank account, into a truly magical and seamless journey. If you are an expert front-end developer who obsesses over meticulous polish and world-class user experience, this is your chance to lead our continued pursuit of excellence. You will be instrumental in two critical areas: first, architecting and scaling our foundational frontend SDKs that empower other teams to efficiently compose their unique onboarding flows; and second, directly developing core, complex components like Know Your Client (KYC), Identity Verification (IDV), and agreement signing. This role requires a visionary who can deliver significant advances in both cutting-edge UX and robust, extensible frontend architecture. While your focus will be purely on the front-end, comfort with occasionally adjusting adjacent backend code is a valuable asset in maintaining end-to-end efficiency.

Requirements:

• Expert experience with Typescript, React, React Native, and familiarity with modern frontend state management, testing, and bundling tools.

• Experience with native mobile development is a plus.

• Experience building and operating scalable frontend components and services.

• Experience with frontend performance profiling and optimization.

• Nice to have experience with backend languages like Ruby / SQL / Java (Kotlin) and GraphQL, reflecting the occasional need to touch backend code to serve frontend work.

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.

• Complete your first feature implementation and ship your first meaningful contributions to production.

Within 3 months, you'll:

• Consistently deliver high-quality code with minimal need for unblocking, demonstrating strong ownership of the end-to-end feature lifecycle.

• Buddy up for your first on-call rotation to help identify and resolve production issues and bugs clients have experienced.

• Support over a million clients on their financial journey by shipping your first project or feature in a secure, and scalable way. 🚀

• You are actively developing a deep understanding of our business objectives and key technical challenges, enabling you to proactively identify areas for improvement and propose future solutions.

Within 6 months, you'll:

• Lead the planning, technical design, and execution of a major feature or initiative, ensuring alignment with our frontend architectural north star.

• Effectively break down large technical work items, develop medium to long-term plans, and delegate tasks to maintain high team throughput.

• Reliably ship new features to our clients, following our best practices such as shipping daily, writing automated tests and monitoring.

• Collaborate with other developers on the team while mentoring and providing continuous feedback via code reviews.
