Job Description Frontend Developer

We are seeking a frontend developer to build a React-based internal application that enables scientists to interact with complex, multi-step Nextflow pipelines through a modular and scalable UI framework. The app will be deployed on an internal production server and must support long-term maintainability with minimal maintenance.

You will be responsible for building a React UI that dynamically renders forms from YAML/JSON configurations specific to defined workflows. The UI will interact with backend services via structured RESTful APIs, and is designed to optionally support integration with future database-backed project states.

Responsibilities

• Develop a modular, React-based frontend using React Router and React Hook Form for dynamic forms and tab navigation
• Build a config-driven UI for stakeholders workflows, adding new pipelines using YAML config
• Implement logic for gating tab access based on pipeline step status (e.g., file flags or API responses)
• Integrate with a RESTful API backend (e.g., FastAPI) using JSON payloads for project data, pipeline parameters, and job states
• Implement client-side validation and interact gracefully with backend error handling
• Set up CI/CD pipelines using GitHub Actions for linting, testing, and Docker-based deployment
• Produce clean, well-documented code and assist with knowledge transfer to internal staff
• Design for long-term maintainability, even in the absence of new feature development
• Tech Stack
• Frontend: React, React Router, React Hook Form
• Backend Integration: RESTful APIs (FastAPI or similar)
• Validation: JSON schema or Pydantic (alignment between frontend/backend validation)
• DevOps: Docker, GitHub Actions (CI/CD), unit testing (Jest or similar)

Qualifications

• 3+ years professional experience developing production-grade frontend applications
• Strong proficiency in JavaScript or TypeScript, React, and modern frontend build systems
• Ability to design and build dynamic forms from schema definitions (JSON/YAML)
• Familiarity with API-first backend integration, especially with FastAPI or similar Python-based frameworks
• Familiar with Git, containerized development, and test automation pipelines
• Demonstrated ability to write clean, maintainable, and well-documented code

Preferred

• Experience with Nextflow or similar bioinformatics or scientific data pipelines
• Familiarity with lineage tracking or versioning logic in scientific data systems
• Exposure to form-driven applications where state gating is important
• Deliverables
• A standalone, production-grade web application, fully self-contained and designed to operate without requiring active future development
• Structured JSON output for every pipeline step to enable future provenance and lineage tracking
• Documentation, usage guide, and Docker image suitable for long-term internal use
• UI foundation that allows revisit, rerun, and input-version selection per tab for completed projects
