Requirements
  • Deep Web Ecosystem Expertise: Extensive professional experience with React, modern JavaScript/TypeScript, and building cross-platform apps wrapped in Electron and React Native.
  • Application-Layer Focus with Backend Literacy: Strong experience consuming complex internal APIs and managing frontend state, complemented by a solid understanding of database design and backend architecture for when custom services are required.
  • Architectural & DevOps Autonomy: Demonstrated ability to build web environments from scratch, including configuring optimized developer workflows, automated testing, and deployment pipelines.
  • Pragmatic & Fast-Paced Problem Solving: A proven track record of operating in a "tiger team" style capacity—capable of rapidly prototyping and delivering high-impact features under tight timelines for enterprise partners.
Responsibilities
  • Productize Core Utilities: Transform an existing library of internal scripts, data importers, and management tools into reliable, production-ready web applications.
  • Migrate & Innovate Workflows: Decentralize complex workflows (such as group administration and user management) out of traditional thick clients and rebuild them into seamless web and hybrid experiences.
  • Serve as a "Tiger Team" Catalyst: Act as a high-mobility rapid responder to build bespoke tools, custom league integrations, and special project solutions for high-profile clients where pivoting our core platform (Focus) is too heavy.
  • Establish Engineering Standards: Define modern web best practices, set up robust CI/CD pipelines, and collaborate with Catapult’s wider web divisions to align technology stacks.
