We are seeking a Senior Web Developer with deep expertise in Next.js + React to lead the architecture and development of our user-facing dashboard. This isn’t just another CRUD app — the dashboard orchestrates long-running workflows, displays high-volume biological and model data, and interacts with systems like Airflow, MLflow, and Jupyter. The complexity is real — and elegant frontend design is what makes it usable. If you are exceptional at Next.js and React, understand how to structure component architectures that scale, and enjoy creating durable, well-designed UI systems, this is the role.
Responsibilities
- Own and evolve the React + Next.js application architecture
- Create robust UI patterns for complex workflows, logs, job status, and model results
- Design state management strategies using tools like React Query / TanStack Query
- Build clean and understandable abstractions around remote services (Airflow, MLflow, Jupyter)
- Define, implement, and maintain RBAC policies aligned with product requirements and security best practices
- Write testable UI code and use mocking effectively in unit and integration tests
- Collaborate closely with product, backend, and ML engineers to shape user workflows
Requirements
- 4+ years of experience building production React applications
- React — component architecture, hooks, memoization, rendering patterns, suspense
- Next.js — routing, data loading strategies, server vs client rendering decisions
- TypeScript — types that clarify code, not complicate it
- State management at scale — e.g., React Query, Recoil, Zustand, MobX, etc
- Authentication, authorization, and RBAC — implementing secure auth flows, role-based access control, and permission models using AWS Amplify Gen 2 and Cognito
- API design — crafting clear, consistent interfaces and integrating complex backend data structures (type safety with tRPC and zod)
- Experience with modern TypeScript ORM frameworks such as Prisma or Drizzle ORM
- Deploying frontend services using Docker on AWS
Nice to Have
- Security & Reliability: Experience implementing web security best practices, including input validation, CSP headers, and safe API interaction
- Unit, integration, and end-to-end testing (Jest, React Testing Library, MSW, Cypress, Selenium, or Playwright)
- UI / UX & Design Systems: Experience working with component systems such as shadcn/ui, with attention to consistency, accessibility, and maintainable design patterns
- Strong UI/UX sensibility for scientific tools and data-rich interfaces, including experience collaborating in Figma and applying layout and usability principles
- Cloud, DevOps & Deployment: Experience deploying and managing applications on AWS using Infrastructure as Code (e.g., Terraform) and containerized workflows (Docker, Docker Compose)
- Familiarity with Kubernetes-based deployments, including Helm charts and GitOps-style workflows
- Data, ML & Scientific Tooling: Experience with machine learning, computational biology workflows, or data-intensive dashboards
- Familiarity with platforms and APIs such as Airflow, MLflow, or Jupyter Server
