About the Role 

The Senior Software Engineer leads implementation for significant projects or major components, mentors junior engineers, and solves complex problems with high autonomy while collaborating cross-functionally. This position is part of a cross-functional software engineering team comprised of software engineers and QA automation engineers, and reports to an Engineering Team Lead. 

In this role, you will focus on building polished, performant, and accessible frontend experiences using React and the modern JavaScript ecosystem, playing a key part in shaping UI architecture decisions and driving frontend engineering excellence. 

Key Responsibilities

• Architect and build scalable, reusable component libraries and design system integrations that ensure consistency across the product. 

• Decompose complex problems into milestones; translate acceptance criteria and design specs into robust, accessible UI solutions. 

• Mentor engineers through code reviews, pairing, and technical guidance; elevate team frontend capabilities. 

• Influence engineering practices (testing, design hygiene, performance, accessibility) to raise overall quality. 

• Contribute to proofs-of-concept and prototypes to validate UX approaches and reduce delivery risk. 

• Collaborate effectively with designers, product managers, QA, and backend engineers throughout development and testing. 

• Other duties as assigned. 

Qualifications 

Required 

• Bachelor’s degree or equivalent practical experience. 

• 6+ years of professional software engineering experience, with a strong focus on frontend development. 

• Deep proficiency in React, including hooks, context, and component lifecycle patterns. 

• Strong command of TypeScript and modern JavaScript (ES6+). 

• Proven experience building and consuming RESTful APIs and integrating with backend services. 

• Solid understanding of HTML5, CSS3, and responsive/adaptive design principles. 

• Experience with state management solutions (e.g., Redux, Zustand, React Query). 

• Familiarity with build tooling and bundlers (e.g., Vite, Webpack). 

• Strong fundamentals in software design, debugging, and maintainable coding practices. 

• Demonstrated ability to lead technical delivery, mentor others, and handle ambiguity effectively. 

• Track record of raising engineering quality (performance, accessibility, testing, maintainability). 

• Experience with frontend testing frameworks (e.g., Jest, React Testing Library, Cypress). 

• Experience participating in estimation and sprint planning. 

• Proficiency with version control systems (Git) and defect-tracking tools (e.g., Jira). 

• Strong written and verbal communication skills. 

• Detail-oriented, with strong analytical and problem-solving skills. 

• Demonstrated growth mindset — self-driven learning and continuous improvement. 

• Ability to work in a fast-paced, dynamic environment and balance multiple priorities. 

Nice to Have 

• Experience using AI tools (e.g., GitHub Copilot, Claude, v0) to accelerate frontend development. 

• Familiarity with cloud platforms, e.g. AWS or Azure, including deploying frontend applications (CDN, S3, static hosting). 

• Experience with server-side rendering or meta-frameworks (e.g., Next.js, Remix). 

• Knowledge of micro-frontend architecture patterns. 

• Background in web accessibility standards (WCAG 2.1) and assistive technology testing. 

• Exposure to CI/CD pipelines and DevOps practices for frontend deployments. 

• Experience with animation libraries (e.g., Framer Motion) or data visualization tools (e.g., D3.js, Recharts). 

What Success Looks Like 

• Delivers major frontend initiatives with predictable execution and clear stakeholder communication. 

• Builds UI components and experiences that are polished, performant, and accessible across devices. 

• Raises team performance through mentorship and improved frontend engineering practices. 

• Resolves complex technical challenges efficiently and leaves the codebase healthier than before.
