Job description

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 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

What we are looking for

Must-Have

• 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
