We are seeking skilled Full Stack Developers to join our engineering team and build end-to-end features across our React frontend and .NET GraphQL backend. You will work across a up-to-date React monorepo and a robust C# API layer designing responsive UIs, writing GraphQL queries and mutations, implementing business logic, and working with our SQL Server database.This is a high-impact role where your work directly shapes the experience of elite athletes and the professionals who support them.

You'll work across a modern, full stack architecture:

Frontend Layer Technology

- FrameworkReact 19 + TypeScript 5.8 (strict mode)
- BuildVite 5, Node 24+
- UI ComponentsMantine v8, Tailwind CSS
- Data VisualizationChart.js, Plotly.js, Rechart
- State ManagementZustand, XState (state machines)
- API LayerGraphQL (urql) with full codegen pipeline
- AuthenticationAzure AD / MSAL
- RoutingReact Router 7, Generouted (file-based)
- TestingVitest, Testing Library, Storybook 8
- Rich ContentTiptap editor, FullCalendar
- ValidationZod
- ObservabilityAzure Application Insights
- CI/CDAzure Static Web Apps

The frontend is a monorepo hosting multiple apps (Admin, Partner, Public, Report) with shared packages and typed GraphQL codegen.

Backend Layer TechnologyLanguage

- C# 12 / .NET 8
- GraphQL
- HotChocolate v15 (ASP.NET Core)
- ORMEntity Framework Core 8 (SQL Server)
- AuthenticationJWT Bearer + Microsoft Identity Web + custom ApiKey scheme
- Background TasksAzure Functions (isolated process, .NET 8)
- MessagingAzure Service Bus
- ConfigurationAzure App Configuration (with refresh/sentinel pattern)
- EmailSendGrid
- PaymentsSquare
- TestingxUnit + Snapshooter + Coverlet
- CI/CDGitHub Actions (CI) + Azure DevOps Pipelines (CD)

IntegrationsThe backend integrates with a variety of external services including HubSpot (CRM), Square (payments), SendGrid (email), Slack (notifications), OpenAI (AI features), Microsoft Graph (Azure AD / M365), Azure Blob Storage (file storage), and specialized sports-tech platforms like Hawkin (force plates) and HumanGo (training platform).

Responsibilities

- Build features end-to-end Design and implement complete features from the React UI through to the .NET GraphQL API and SQL Server database, including schema design, mutations,



and responsive interfaces.
- Build data-driven UIs — Develop responsive, performant interfaces for athlete assessment dashboards, performance reports, and scheduling workflows using React 19, TypeScript, and Mantine.
- Visualize complex data — Create compelling charts, force-time curves, and animated data displays using Chart.js, Plotly, and SVG to communicate physiological metrics to athletes and coaches.
- Design and extend the GraphQL API — Write HotChocolate queries and mutations in C#, define types and input types, implement DataLoaders to prevent N+1 queries, and maintain efficient data access with Entity Framework Core.
- Own the GraphQL integration layer — Write typed frontend queries and mutations, maintain the codegen pipeline, and ensure efficient data fetching with urql and Graphcache.
- Work with the database — Design EF Core models, write migrations, and implement repository patterns against SQL Server.
- Build background processing — Implement Azure Functions for async tasks such as email delivery, service bus consumers, and third-party integration workflows.
- Ship with confidence — Write unit and integration tests across both frontend (Vitest, Testing Library) and backend (xUnit), document components in Storybook, and participate in thorough code reviews.
- Architect for scale — Contribute to monorepo architecture decisions, shared component libraries, API design patterns, and cross-app patterns that support multiple user-facing applications.
- Stay current — Actively contribute to the evolution of our tech stack, evaluate new tools, and champion best practices in accessibility, performance, security, and developer experience.

Qualifications Required

- 5+ years of professional full stack development experience with React/TypeScript and a server-side language (C#/.NET strongly preferred).
- Strong understanding of component architecture,



hooks, context, and modern React patterns.
- Experience with GraphQL — both as a consumer (urql, Apollo) and ideally as a backend implementer (HotChocolate, Apollo Server, or similar).
- Working knowledge of relational databases and ORMs (SQL Server, PostgreSQL, Entity Framework Core, or similar).
- Familiarity with state management solutions (Zustand, Redux, XState, or similar).
- Experience with modern build tools (Vite, esbuild, or webpack) and monorepo patterns.
- Solid understanding of CSS architecture — CSS Modules, Tailwind, or CSS-in-JS.
- Experience with testing across the stack — unit tests, component tests, integration tests, and snapshot/visual regression.
- Proficiency with Git, code review workflows, and CI/CD pipelines.
- Excellent problem-solving skills and ability to collaborate effectively in a distributed team.

Nice to Have

- Experience with C# / .NET 8 and ASP.NET Core.
- Experience with HotChocolate GraphQL framework.
- Familiarity with Entity Framework Core migrations and database-first/code-first patterns.
- Experience with Azure services (Functions, Service Bus, App Configuration, Static Web Apps, MSAL/Entra ID, Application Insights, Blob Storage).
- Experience with Mantine or other headless/composable UI libraries.
- Background in sports science, health tech, or data-intensive applications.
- Experience with Storybook for component-driven development.
- Familiarity with file-based routing (Generouted, Next.js, or similar).
- Experience with event-driven architectures and message queues.

Benefits

- Cutting-edge stack — React 19, .NET 8, HotChocolate GraphQL, TypeScript strict mode, full GraphQL codegen — we invest in modern tooling across the entire stack.
- Meaningful impact — Your code directly helps athletes improve performance and supports physiologists in delivering better care.
- Growth opportunities — Fast-paced startup environment with room to shape architecture and technical direction across frontend and backend.
- Collaborative culture — Inclusive team with a focus on personal and professional development.
- Unique domain access — Work alongside experienced sports coaches and exercise physiologists.
