The Role 

We are hiring a Senior Frontend Developer to help build and evolve the web experience at the heart of our platform. You will own significant frontend features end to end, and you will care as much about the problem being solved for the user as the code that solves it. 

You will build in React and TypeScript, partnering closely with product and design to turn complex business problems into interfaces that feel simple. As one of our senior frontend engineers, you will also help modernize our frontend tooling and practices, and raise the bar for quality across the team. 

You will set direction on frontend patterns and architecture while staying close to the code: shipping features alongside the team, reviewing pull requests, and collaborating with engineers across the stack. We are a small, focused company, and the decisions you make show up directly in the product. 

What You'll Do 

• Build, review, and test frontend features end to end in React and TypeScript, contributing directly to the product our customers use every day. 

• Partner closely with product and design to translate business problems into intuitive, polished user experiences. 

• Collaborate with our backend engineers to define clear API contracts and deliver features that work seamlessly across the stack. 

• Help modernize our frontend tooling, standards, and reusable components, raising the bar for quality across the team. 

• Build and evolve the shared component library that powers a consistent, accessible experience across the product. 

• Optimize the performance of data-dense interfaces, from large tables and lists to real-time views. 

• Drive technical discussions and contribute to frontend architecture decisions. 

• Work closely with Product to validate ideas and build prototypes when needed. 

• Use AI tools to accelerate your work, and share effective practices with the team. 

What We're Looking For 

• You bring 5+ years of professional frontend engineering experience building production web applications. 

• You have deep expertise in React and TypeScript, on a strong foundation of core JavaScript. 

• You have a product mindset: you are motivated by solving real problems for users, not just shipping tickets. 

• You have a track record of owning features end to end and making sound architectural tradeoffs. 

• You have experience with modern state management, particularly handling server state and data fetching in complex applications. 

• You have optimized the performance of data-dense interfaces and know how to keep large, interactive UIs fast. 

• You have built or contributed to a shared component library or design system. 

• You have a solid grasp of web accessibility standards and care about building inclusive interfaces. 

• You collaborate closely and effectively across disciplines, particularly with design and backend engineering. 

• You have excellent communication skills, with the ability to explain technical concepts clearly to a range of audiences. 

• You are eager to use AI tools to accelerate your own engineering work and inclined to share effective practices with the team. 

Nice to Have 

• A willingness to take on some backend development, or to learn it as needed. 

• Experience modernizing or migrating a legacy frontend codebase. 

• A sensibility for the security, audit, and reliability expectations of regulated industries (finance or similar). 

Why Join Us 

• Own significant parts of the frontend experience of an enterprise SaaS platform used by top-tier financial institutions.
• A senior role with real technical scope, where the decisions you make show up directly in the product.
• Work with a collaborative, product-focused engineering culture at a small enough company that your decisions matter.

Compensation and Benefits

• For this role, candidates located in Ontario can expect a base salary range of CAD $120,000-170,000. Placement within the range is determined by relevant experience, skills, and role level.
• In addition to base salary, this role is eligible for an end-of-year performance bonus and a comprehensive benefits package including health and dental coverage.
• Comprehensive medical and dental insurance coverage, hybrid working environment, flexible time-off.
