Working hours: 11:30am - 4pm CT or at least 2hrs CT overlap
About the role:
We’re seeking a Senior Software Engineer (Front End) to own and deliver public-facing and internal features that improve user experience, performance, and SEO. You will work cross-functionally with PMs, designers, backend engineers, and QA on an agile team and be responsible for design, implementation, testing, and production support.
- Design and implement customer-facing features using Angular, React and TypeScript that meet performance, accessibility (a11y), and SEO goals.
- Collaborate with product and design to translate requirements into technical designs and estimates.
- Write clean, testable code and maintain a component-driven design system.
- Contribute to architecture and non-functional requirements (scalability, security, observability).
- Improve site speed and Core Web Vitals by optimizing bundles, rendering strategy, and caching.
- Implement and maintain automated tests (unit, integration, and E2E).
- Participate in sprint planning, code reviews, and delivery processes from story inception through production rollout.
- Support production services on a rotation basis and troubleshoot incidents to minimize downtime.
- Mentor teammates and help raise the team’s engineering standards.
What we’re looking for:
- Must have:
5+ years professional front-end development experience (or equivalent demonstrable experience).
3+ years building production applications with React and TypeScript.
Strong experience with modern front-end tooling: bundlers (webpack/Vite/Gulp), state management, component libraries, and design systems.
Proven ability to deliver features used in production and own them through lifecycle.
Proven experience using agentic AI tools (such Claude or GitHub Copilot) to accelerate front-end development workflows, including code generation, component building, and performance optimization.
Ability to mentor team members on effective AI usage; establishing best practices, identifying high-leverage opportunities, and fostering a culture of thoughtful, responsible AI adoption across the engineering team.
Experience embedding generative AI features directly into user-facing applications, such as intelligent interfaces, dynamic content generation, and LLM-powered experiences.
Experience writing automated tests (Jest/React Testing Library, Cypress or similar).
Solid understanding of web performance optimization, SEO fundamentals, and accessibility best practices
Familiarity with secure development practices and basic security testing concepts.
Experience working in agile teams and collaborating across disciplines.
Clear written and verbal communication skills.
Exposure to AI-assisted development workflows and prompt engineering best practices.
- Nice to have
Experience with server-side rendering / hybrid frameworks (Next.js) and edge caching strategies.
