About the role

As a Senior Front End Engineer on our trading and investing teams, youll own meaningful slices of the experiences at the heart of Canadas first zero-commission brokerage - the surfaces over 4 million Canadians rely on, and invest with. This is a pipeline role across several frontend-focused teams, including Order Execution and Options Trading, and well match you to the team where your experience and interests fit best.

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. Youll 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 youll 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 — influence what we build, how we build it, and where we go next

• 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 — clients notice the moment something is slow or wrong

• Leverage AI-centric workflows to ship faster and safer — we invest heavily in AI tooling and expect senior engineers to push the frontier of how we use these tools

• 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 that real users depend on

• Strong frontend fundamentals with React and TypeScript, and ideally React Native — you build performant, reliable client experiences and understand how they behave under real-world conditions.

• Native mobile experience (Swift/iOS or Kotlin/Android) is a strong plus, whether youve built native apps directly or directed and reviewed native work

• An AI-first development workflow that doesnt compromise on rigour — youve moved beyond AI as autocomplete into genuinely agentic workflows, and bring the judgment to know when the model is wrong, where the risks are, and what verification a change needs before it touches production

• Product judgment and a maker-owner mindset — you care about the client problem, simplify complexity, and want to own and grow a domain over time, not just ship the next ticket

• Technical leadership and strong communication — you raise the bar through your code, reviews, and design docs, navigate ambiguity, and bring others along with a collaborative, low-ego approach

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 — helpful for working across the stack, but not a requirement; depth and willingness to ramp matter more

• Experience in a fast-moving environment where engineers have broad ownership and meaningful influence over product decisions

• Passionate about trading and investing, perhaps even an active investor or trader yourself, and you use that perspective to build experiences that feel intuitive to people managing their own money.
