• Work daily with teammates and product partners to reach shared goals and deliver AI-powered legal data features at large scale.
• Mentor engineers through expertise, teamwork and sound judgment.
• Define engineering standards through code and design reviews, patterns, best practices and coaching.
• Keep team work aligned with product strategy and delivery dates, and clear the technical obstacles in the way.
• Lead reliability work, on-call practices, incident response and root cause analysis for the services the team owns.
• Set the frontend architecture vision across platform teams and lead shared infrastructure, design-system components and Micro Frontend integration using React, TypeScript and PrimeReact, alongside Staff and Principal Engineers, product, UX and engineering leadership.
• Guide accessibility (WCAG), performance (lazy loading, code splitting, asset optimization, telemetry), test automation (unit, integration and end-to-end with Jest, Cypress or Playwright) and maintainability, and evolve CI/CD, component versioning and documentation.
• Lead exploration of AI-enhanced UI and UX, such as smart component behavior, generative layouts and adaptive interfaces, and grow technical leadership through architecture reviews, pair programming, mentoring and hands-on development.

Requirements

• 7+ years of frontend work building and operating cloud-native systems, including at least 2 years in a technical or lead engineering role.
• A track record of setting technical direction and leading teams effectively.

• Advanced JavaScript (ES6+), TypeScript and React skills, including building and managing shared design systems and Micro Frontend or modular UI architectures in large systems.
• Solid command of semantic HTML, modern CSS and pre-processors (SASS/LESS), responsive design, WCAG accessibility, frontend performance profiling and cross-browser testing, plus CI/CD, bundlers (Vite, Webpack), test frameworks and RESTful or GraphQL APIs.
• Preferred: prior people-lead or technical-lead experience.
• Preferred: experience in regulated or large-scale environments.
• Preferred: familiarity with AI development tools such as GitHub Copilot, Cursor or Claude Code.
• Preferred: experience working in global or highly distributed organizations.
• Preferred: background in.NET or other backend technologies (Node.js, Python) for cross-stack collaboration.
• Preferred: understanding of UX principles and design-system governance, with design-to-code alignment and familiarity with design and prototyping tools such as Figma.
• Preferred: experience with AI-driven UI and UX, such as chatbot integration, recommendation engines, personalization or adaptive layouts.
• Listed skills: documentation, innovation, leadership, problem solving, process improvement, project management, quality assurance (QA), risk management, technical knowledge and troubleshooting.
