Senior Software Developer - Clients & Accounts

Wealthsimple TechnologiesToronto, ON
CA$151,200 - CA$189,000Hybrid

About The Position

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 building and operating scalable frontend components and services.
  • Experience with frontend performance profiling and optimization.

Nice To Haves

  • Experience with native mobile development is a plus.
  • Experience with backend languages like Ruby / SQL / Java (Kotlin) and GraphQL, reflecting the occasional need to touch backend code to serve frontend work.

Responsibilities

  • Architecting and scaling foundational frontend SDKs.
  • Developing core, complex components like Know Your Client (KYC), Identity Verification (IDV), and agreement signing.
  • Adjusting adjacent backend code to maintain end-to-end efficiency.
  • Consistently deliver high-quality code with minimal need for unblocking, demonstrating strong ownership of the end-to-end feature lifecycle.
  • Support over a million clients on their financial journey by shipping your first project or feature in a secure, and scalable way.
  • 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.
  • 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.
