Senior Frontend Developer

About Us Appnovation is a global, full-service digital partner that combines Strategy, Experience & Design, Engineering and Managed Services. We build digital solutions that deliver real impact today and serve as foundations for future growth. Bold ambition. Practical action. Endless possibilities. About The Role 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. Key Responsibilities Building and maintaining application features in Next.js, React, and TypeScript, including server-side rendering, routing, and state management decisionsDeveloping reusable, accessible components in a component-driven model using Shadcn/UI and Tailwind CSS, extending the existing design system rather than working around itIntegrating with .NET REST APIs, including handling loading, error, empty, and partial-failure states properly rather than assuming the happy pathBuilding interfaces that accurately reflect asynchronous and long-running backend processes, including in-progress, retrying, and failed statesImplementing authentication flows against Keycloak using OAuth 2.0 and OpenID Connect, and rendering conditionally against OpenFGA-driven permissionsBuilding data-dense reporting and analytics views over backend query results, with attention to performance at realistic data volumesWriting and maintaining Playwright end-to-end coverage for the flows you build, and contributing to the shared test suiteMeeting WCAG 2.x Level AA, and treating accessibility as part of the build rather than a remediation passProducing implementation plans for significant changes, and delivering work in small, reviewable merge requestsParticipating in code review, responding to CodeRabbit findings, and keeping GitLab CI/CD pipelines greenParticipating in refinement, planning, review, and retrospective as a member of a self-directed scrum team, and raising missing business or UX decisions earlyMaintaining frontend technical and component documentation as part of the definition of done, not after itResolving defects and supporting post-release stabilization of recently delivered functionalityMentoring less experienced developers through code review and pairing What we are looking for Must-Have Bachelor's Degree in computer science, software engineering, or equivalent practical experience6+ years of web development experience, having delivered production applications as part of a teamStrong command of React, including hooks, composition patterns, state management, routing, and server-side renderingProduction experience with Next.js, including App Router, rendering strategies, and data fetching patternsStrong TypeScript skills - you use the type system to prevent defects, not to satisfy a linterExpert 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 sitesExperience consuming REST APIs, including error handling, retry behaviour, and designing UI around asynchronous operationsExperience building and maintaining component libraries or design systems, and working with design tokens and tools such as StorybookExperience implementing authentication in a frontend application against an identity provider using OAuth 2.0 and OpenID ConnectExperience building role- or permission-sensitive interfaces where what a user can see and do variesExperience 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 assumptionsWorking knowledge of WCAG 2.x Level AA and practical accessible-component implementationStrong understanding of frontend performance - bundle size, rendering cost, and behaviour at realistic data volumesComfortable working inside an existing codebase and an established set of engineering and design standards, rather than setting your ownStrong understanding of version control, CI/CD, and peer review through merge requestsStrong understanding of security and privacy by design principlesExperience working with agile delivery methodologies, including refinement, planning, review, and retrospectiveExperience mentoring other developersMust be located in British Columbia, Canada Technologies Core: Next.js, React, TypeScript, JavaScript, HTML5, CSS3UI and Styling: Shadcn/UI, Tailwind CSS, component-driven development, design tokens, StorybookIntegration: REST APIs, OpenAPI/Swagger consumptionIdentity and Authorization: Keycloak, OpenFGA, OAuth 2.0, OpenID Connect, SSO, role- and policy-based authorization in the UITesting: Playwright end-to-end testing, component and unit testing (Jest / Vitest, React Testing Library)Accessibility: WCAG 2.x Level AA, semantic HTML, ARIA, keyboard and screen reader supportEngineering and Collaboration: GitLab, GitLab CI/CD, CodeRabbit automated code review, Jira, Jira Product Discovery, Jira Service Management, ConfluenceBackend context: C#, .NET Core, .NET APIs, PostgreSQL, ClickHouse, Temporal workflows, event-driven pub/sub Nice to Have Familiarity with C# and .NET - enough to read backend code, trace an issue across the stack, and have a productive conversation about an API contractFamiliarity with fine-grained authorization models (OpenFGA, Zanzibar-style ReBAC)Experience building analytics or reporting interfaces over large datasets, including data visualizationExperience with workflow-driven or long-running process UIsSaaS product delivery experience, particularly through a pilot-to-GA transitionExperience 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 monitoringPWA, service workers, and advanced performance optimizationExperience in a consulting or client-facing delivery environment Who you are 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.
