Software Engineer III (Frontend)

We’re looking for a Frontend Software Engineer III to help build and evolve customer-facing applications across modern SPA frameworks and server-rendered systems.

This role is for a strong, independent engineer who can own frontend systems end-to-end — from UX collaboration and architecture decisions through implementation, performance optimization, and production support.

Our frontend ecosystem includes React, Vue, Twig-based server-rendered templates, and Bootstrap for styling. Experience working across both SPA and traditional rendered environments is important. You’ll work on high-visibility, revenue-impacting products where performance, usability, and clarity matter.

We expect engineers at this level to leverage modern tooling — including AI-assisted development — to improve velocity, test coverage, and code quality while maintaining strong engineering judgment.

COMPENSATION: The anticipated annual base salary range for this position is $140,000. Actual compensation may vary based on work experience, education, and skill level.  

What You’ll Do

• Design, build, and maintain modern frontend applications using React
• Maintain and improve Twig-rendered UI templates
• Build and extend responsive UI components using Bootstrap
• Collaborate with product, backend, and design teams to deliver polished features
• Own frontend architecture decisions within your domain
• Improve application performance, accessibility, and responsiveness
• Utilize AI-assisted tools to accelerate implementation, refactoring, and test creation
• Participate in code reviews and mentor mid-level engineers
• Contribute to shared component libraries and frontend standards
• Support production systems and help resolve user-facing issues

Technical Responsibilities:

• Build reusable, well-tested UI components
• Implement thoughtful state management patterns
• Optimize bundle size, rendering performance, and Core Web Vitals
• Integrate frontend systems with REST and/or GraphQL APIs
• Maintain clean separation between presentation, logic, and data
• Ensure accessibility (WCAG), cross-browser compatibility, and responsive design
• Write unit and integration tests 
• Leverage AI tools responsibly to increase development speed without sacrificing quality
• Contribute to CI/CD and frontend build pipelines

Technical Environment (Representative):

• Frameworks: React
• Server Rendering: Twig
• Languages: TypeScript, JavaScript
• Styling: Bootstrap (primary), Tailwind (plus), SCSS
• Build Tools: Vite, Webpack, or equivalent
• APIs: REST (primarily), some GraphQL
• Infrastructure: AWS, Docker
• Observability: Datadog, Sentry
• Developer Tooling: AI-assisted coding tools integrated into workflows

• 5+ years of professional frontend engineering experience
• Strong experience with React and/or Vue
• Solid understanding of JavaScript fundamentals and modern ES standards
• Experience working with server-rendered template systems (Twig or similar)
• Strong experience with Bootstrap or similar CSS frameworks
• Experience building production-grade UI systems at scale
• Deep understanding of browser performance and debugging tools
• Ability to own complex features independently
• Experience using AI development tools to enhance productivity and testing workflows
• Strong communication skills and product awareness

Nice to Have:

• Experience with Tailwind
• Experience migrating legacy templates to SPA frameworks
• Experience building or maintaining design systems
• Strong TypeScript proficiency
• Familiarity with A/B testing frameworks
• Experience in high-traffic, data-heavy environments
• Exposure to backend systems (Go, PHP, Ruby, or Python)

Expectations at Level III

• A Software Engineer III:
• Operates independently on large features
• Makes sound architectural decisions within scope
• Improves code quality and frontend standards
• Mentors junior engineers
• Communicates tradeoffs clearly to product and design
• Uses modern tooling — including AI — thoughtfully and responsibly
• Is comfortable owning production systems
