Job Description

About the role:

We are seeking a highly experienced and technically skilled Senior Front-End Engineer to join Sitecore's new technology hub in Sri Lanka. The ideal candidate is a technical expert with a passion for solving complex problems and writing high-quality software solutions. You will be expected to take on significant technical challenges, owning major features and influencing key architectural decisions while helping to elevate the skills of the engineers around you.

Key responsibilities:

• Own the solution design and implementation of large-scale, complex front-end features from start to finish.
• Elevate the team's technical abilities through exemplary code, thoughtful and constructive code reviews, informal mentorship, and hands-on guidance on configuring and optimizing build tools (Vite, Webpack, Rollup).
• Lead key technical decisions across state management, performance optimization, and front-end architecture, ensuring scalable and maintainable solutions.
• Collaborate closely with cross-functional teams (Design, Product, Backend, QA) to shape cohesive, high-quality features and influence product direction.
• Write clean, type-safe TypeScript code aligned with recognized best practices (DRY, SOLID).

Qualifications

Preferred Skills and Experience:

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
• 5+ years of professional software development experience, including 3+ years of deep, hands-on React work.
• Expert-level proficiency in JavaScript/TypeScript, HTML5, and CSS3.
• Strong experience with modern build tools, including Vite, Webpack, and Rollup (configuration, optimization, plugin ecosystems).
• Deep understanding of state management strategies and tooling (React Query, Jotai, React Context).
• Experience integrating REST APIs and working with code generation tools such as OpenAPI/Swagger.
• Mastery of modern React patterns: functional components with hooks, custom hooks, component composition, React Server Components, and performance optimization techniques
• Strong CSS architecture and implementation skills, including Flexbox, Grid, Container Queries, and experience with CSS-in-JS or utility frameworks (TailwindCSS preferred).
• Understanding of UI/UX principles and a passion for creating thoughtful, user-centered experiences.
• Solid understanding of Core Web Vitals and front-end performance optimization.
• Strong problem-solving, communication, and collaboration skills.

Nice to have:

• Test-driven development (TDD) experience and mindset.
• Experience with MCP (Model Context Protocol) integration.
• Experience with Next.js, Remix, or other modern React frameworks.
• Monorepo tooling experience (Turborepo, Nx, Lerna).
• Strong understanding of web security fundamentals (XSS, CSRF, CSP).
• Accessibility knowledge (WCAG 2.1 AA standards)
• Experience with REST API code generation tools (OpenAPI, Swagger Codegen)
• Advanced experience with GitHub Actions, such as creating custom actions or complex, multi-stage workflows
• Experience with Agile/Scrum methodologies
• Experience designing or developing agentic UI experiences, where the interface proactively assists the user

Core technologies we use:

• React, TypeScript, JavaScript (ES6+)
• Vite for development, Webpack/Rollup for more complex builds
• React Query, Jotai, React Context for state management
• TailwindCSS and CSS Modules
• Vitest, React Testing Library, Playwright
• GitHub Actions, Docker
• Turborepo with pnpm workspaces
• REST APIs with OpenAPI/Swagger code generation

What matters to us:

• Simplicity over cleverness - complexity should come from the problem, not the solution
• Readability first - we spend more time reading code than writing it
• Well-tested and maintainable - code should be easy for anyone on the team to understand and modify
• Functional and declarative patterns over imperative code
• Type safety - comprehensive TypeScript usage
• Component-driven development with clear separation of concerns
• Testing ownership -- no feature is complete without tests
• Code ownership - if you write it, you maintain it and take responsibility for its quality
