About the role

Key responsibilities & impact

Design, develop, test, and deliver complex production web applications using React and TypeScript
Remain hands-on with development while serving as a technical leader for the engineering team
Own complex features and technical initiatives from design and implementation through testing, deployment, observability, and production support
Lead technical design discussions and make decisions around application architecture, component design, state management, data flows, API integration, performance, security, accessibility, and testing
Work within a monorepo architecture containing multiple applications, shared components, shared libraries, utilities, configurations, dependencies, and common development tooling
Design and evolve reusable React components, shared libraries, common services, hooks, utilities, and engineering patterns
Make decisions around React architecture, component composition, state management, server-state management, routing, caching, error handling, and application lifecycle
Integrate frontend applications with RESTful APIs and backend services
Balance delivery speed, maintainability, scalability, technical debt, developer experience, and long-term architecture
Identify and resolve technical blockers, architectural concerns, dependencies, and delivery risks
Serve as a trusted technical partner to the Engineering Manager
Provide technical direction and mentorship through design reviews, code reviews, pairing, reusable patterns, troubleshooting, and knowledge sharing
Translate ambiguous and complex requirements into clear technical designs and executable engineering work
Establish engineering practices for unit testing, integration testing, automated testing, code quality, security, and regression prevention
Troubleshoot issues across application code, shared libraries, APIs, dependencies, builds, CI/CD pipelines, and production environments
Improve CI/CD pipelines, automated quality gates, build processes, deployment processes, dependency management, and release practices
Improve developer experience, build performance, application performance, maintainability, and engineering efficiency across the monorepo
Collaborate with Product, UX, Architecture, API/backend engineering, SRE, QA, and other engineering teams
Stay current with React, TypeScript, JavaScript, Node.js tooling, testing, build, and frontend engineering practices

Requirements
