Full Job Description

BUILD SOMETHING PEOPLE LOVE Wealthsimple is Canada’s leading financial innovator. The company offers a full suite of simple, sophisticated financial products across managed investing, do-it-yourself trading, cryptocurrency, tax filing, spending and saving. Wealthsimple currently serves more than 4 million Canadians and holds over $125 billion in assets under administration. The company was founded in 2014 by a team of financial experts and technology entrepreneurs, and is headquartered in Toronto, Canada. We're proud of what we've built — and we're just getting started. Read our Culture Manual https://www.wealthsimple.com/en-ca/culture and learn more about how we work https://www.wealthsimple.com/en-ca/careers. About the Team CLIENTS & ACCOUNTS 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 devel
