About the role

Senior Frontend Engineer responsible for architecting the frontend foundation and design system for Handshake AI Enterprise, defining component system, design language, and engineering patterns to scale across the team.

Responsibilities

  • Architect the frontend foundation for Handshake AI Enterprise — component system, design tokens, patterns, and engineering conventions that the whole team builds on
  • Make foundational technology decisions: framework choices, state management, rendering strategy, performance budgets
  • Build shared libraries and abstractions that let other engineers move fast without reinventing the wheel or sacrificing quality
  • Establish code standards, review practices, and documentation that scale as the team grows
  • Collaborate closely with Applied AI and Platform engineers to define clean API contracts and integration patterns
  • Ship production-grade UI for enterprise customer deployments alongside building the foundation
  • Evolve the architecture over time as the team, product, and customer base scales

Qualifications

  • 5–6+ years of frontend engineering experience with a strong architectural track record
  • Deep expertise in ReactJS and TypeScript — you understand the tradeoffs, not just the syntax
  • Proven experience building and maintaining shared component libraries or design systems used by other engineers
  • Strong opinions on frontend architecture — state management, rendering patterns, performance, accessibility — and the ability to defend and evolve them
  • Experience making technology decisions that others depend on, with an eye toward long-term maintainability
  • Comfort working in ambiguous, fast-moving environments where the right answer isn't always obvious
  • Strong communication skills — you'll need to align engineers, product, and design on how things get built
