Senior Software Developer

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 $155 billion in assets under administration.

As a Senior Front End Engineer on our trading and investing teams, you'll own meaningful slices of the experiences at the heart of Canada's first zero-commission brokerage. This is a pipeline role across several frontend-focused teams, including Order Execution and Options Trading.

These are high-visibility, high-stakes surfaces: the order flow across equities, options, and crypto, and the trading experiences active clients use every day. A slow screen or a mishandled order is felt immediately by our clients, so the bar for reliability, performance, and craft is high. You'll bring strong technical judgment, a bias toward action, and a deep sense of ownership, working closely with product managers, designers, and engineers to turn complex, high-stakes problems into simple, reliable trading experiences.

What you'll do:

• Own complex, end-to-end frontend projects across the trading experience - from technical design through implementation, launch, and iteration.
• Build and improve the client-facing surfaces that power our order flow and trading products, with a focus on reliability, performance, and correctness.
• Work on high-stakes client journeys: order entry and execution, options trading, real-time market data, and portfolio experiences across equities, options, and crypto.
• Make thoughtful architectural decisions and help the team balance speed, quality, and scale.
• Partner closely with Product and Design to clarify goals, surface trade-offs, and deliver outcomes, not just features.
• Build with the reliability and observability standards that trading journeys demand.
• Leverage AI-centric workflows to ship faster and safer.
• Raise the technical bar through design reviews, code reviews, documentation, pairing, and mentorship.

What you bring:

• 5+ years of professional software engineering experience, with a track record of shipping production-grade systems.
• Strong frontend fundamentals with React and TypeScript, and ideally React Native.
• Native mobile experience (Swift/iOS or Kotlin/Android) is a strong plus.
• An AI-first development workflow that doesn't compromise on rigour.
• Product judgment and a maker-owner mindset.
• Technical leadership and strong communication.

Nice to have experience:

• Experience building trading, brokerage, or other real-time, high-reliability financial surfaces.
• GraphQL and performance optimization experience.
• Ruby on Rails, Kotlin, or Java experience.
• Experience in a fast-moving environment where engineers have broad ownership.
• Passionate about trading and investing.

• Long-term group savings with employer match.
• 20 vacation days, 4 wellness days, and unlimited sick and mental health days per year.
• Employee resource groups, including Rainbow (2SLGBTQ), Women of WS, and Black at WS.
