What they need


Who you are

  • Bachelor's Degree in computer science, software engineering, or equivalent practical experience
  • 6+ years of web development experience, having delivered production applications as part of a team
  • Strong command of React, including hooks, composition patterns, state management, routing, and server-side rendering
  • Production experience with Next.js, including App Router, rendering strategies, and data fetching patterns
  • Strong TypeScript skills - you use the type system to prevent defects, not to satisfy a linter
  • Expert knowledge of HTML5 and CSS3, and fluency with utility-first CSS (Tailwind CSS or equivalent)
  • Demonstrated experience building complex, stateful application interfaces - forms, workflows, dashboards - rather than primarily content or marketing sites
  • Experience consuming REST APIs, including error handling, retry behaviour, and designing UI around asynchronous operations
  • Experience building and maintaining component libraries or design systems, and working with design tokens and tools such as Storybook
  • Experience implementing authentication in a frontend application against an identity provider using OAuth 2.0 and OpenID Connect
  • Experience building role- or permission-sensitive interfaces where what a user can see and do varies
  • Experience with end-to-end testing (Playwright preferred; Cypress considered), and an understanding of what makes automated tests durable - avoiding hard-coded waits, brittle selectors, shared test state, and environment-specific assumptions
  • Working knowledge of WCAG 2.x Level AA and practical accessible-component implementation
  • Strong understanding of frontend performance - bundle size, rendering cost, and behaviour at realistic data volumes
  • Comfortable working inside an existing codebase and an established set of engineering and design standards, rather than setting your own
  • Strong understanding of version control, CI/CD, and peer review through merge requests
  • Strong understanding of security and privacy by design principles
  • Experience working with agile delivery methodologies, including refinement, planning, review, and retrospective
  • Experience mentoring other developers
  • Must be located in British Columbia, Canada
  • Familiarity with C# and .NET - enough to read backend code, trace an issue across the stack, and have a productive conversation about an API contract
  • Familiarity with fine-grained authorization models (OpenFGA, Zanzibar-style ReBAC)
  • Experience building analytics or reporting interfaces over large datasets, including data visualization
  • Experience with workflow-driven or long-running process UIs
  • SaaS product delivery experience, particularly through a pilot-to-GA transition
  • Experience with Canadian public-sector or education accessibility and data privacy requirements (AODA and provincial equivalents, PIPEDA, provincial FIPPA)
  • Experience with distributed tracing or frontend observability and error monitoring
  • PWA, service workers, and advanced performance optimization
  • Experience in a consulting or client-facing delivery environment
  • You are a product-minded engineer who asks what the user is actually trying to accomplish before deciding how to build it
  • You have experience in customer-facing roles and communicate clearly, including when something is off track
  • You treat a feature as incomplete until it is tested, accessible, documented, and supportable - finishing the code is the middle of the job, not the end

What the job involves

  • As a Senior Frontend Developer, you will build the user-facing application for a modern operational SaaS platform for K-12 education
  • The platform helps school divisions automate administrative processes, manage information across their organization, and surface operational insight - which means the interfaces you build are workflow-driven and data-dense: multi-step forms with real validation consequences, long-running processes whose state the UI has to reflect honestly, role-sensitive views that change shape depending on who is looking, and reporting surfaces backed by real analytical queries
  • This is product engineering rather than marketing site work
  • You will build in Next.Js, React, and TypeScript against
  • NET REST APIs, using Shadcn/UI and Tailwind CSS in a component-driven model, and you will own Playwright end-to-end coverage for the flows you build
  • Authorization is enforced through Keycloak and OpenFGA, so the frontend has to handle OIDC flows and render correctly against fine-grained, policy-driven permissions in a multi-tenant product where an administrator in one school division must never see another's data
  • You will work as part of a dedicated, cross-functional scrum team that operates as an embedded extension of the client's product and engineering organization
  • The team includes business analysis and QA capability and owns assigned product services end-to-end - from refinement through development, testing, documentation, and release readiness
  • You will work directly in the client's repositories and follow their established architecture, design system, and engineering standards
  • The platform is moving from pilot deployments toward general availability, so the work is real-user-facing from the start
  • Building and maintaining application features in Next.js, React, and TypeScript, including server-side rendering, routing, and state management decisions
  • Developing reusable, accessible components in a component-driven model using Shadcn/UI and Tailwind CSS, extending the existing design system rather than working around it
  • Integrating with .NET REST APIs, including handling loading, error, empty, and partial-failure states properly rather than assuming the happy path
  • Building interfaces that accurately reflect asynchronous and long-running backend processes, including in-progress, retrying, and failed states
  • Implementing authentication flows against Keycloak using OAuth 2.0 and OpenID Connect, and rendering conditionally against OpenFGA-driven permissions
  • Building data-dense reporting and analytics views over backend query results, with attention to performance at realistic data volumes
  • Writing and maintaining Playwright end-to-end coverage for the flows you build, and contributing to the shared test suite
  • Meeting WCAG 2.x Level AA, and treating accessibility as part of the build rather than a remediation pass
  • Producing implementation plans for significant changes, and delivering work in small, reviewable merge requests
  • Participating in code review, responding to CodeRabbit findings, and keeping GitLab CI/CD pipelines green
  • Participating in refinement, planning, review, and retrospective as a member of a self-directed scrum team, and raising missing business or UX decisions early
  • Maintaining frontend technical and component documentation as part of the definition of done, not after it
  • Resolving defects and supporting post-release stabilization of recently delivered functionality
  • Mentoring less experienced developers through code review and pairing
