Senior Software Engineer (Frontend Platform)

• As a Senior Software Engineer on the Frontend Platform Team, you’ll help build and evolve that foundation. You’ll work on the systems, libraries, and workflows that make it easier for product engineers to deliver great frontend experiences—faster, safely, and with less duplicated effort
• Frontend Platform is a small, high-leverage team with a broad mandate. We own Handshake’s design system and component libraries, frontend accessibility, frontend infrastructure in CI/CD, developer tooling, and cross-cutting UI concerns
• You’ll treat these capabilities as products for frontend engineers, designers, and product teams. You’ll help turn recurring problems into reusable solutions, establish thoughtful standards and paved paths, and create a frontend platform that scales with Handshake’s products and engineering organization
• Build and evolve reusable TypeScript and React components, patterns, APIs, documentation, and tooling that are used across multiple Handshake applications
• Help shape the design system as a living product, balancing consistency and accessibility with the flexibility product teams need to solve customer problems
• Improve the frontend developer experience by creating clear paved paths for local development, testing, builds, releases, and ongoing maintenance
• Use AI tools heavily as part of your day-to-day engineering workflow: to understand code, prototype, implement, test, debug, refactor, document, and review changes, while applying sound human judgement
• Build reusable AI-enabled frontend workflows for the rest of the organization, including agent-ready documentation and context, rules, linters, structured CI review, accessibility and visual checks that helps product teams and agents contribute safely without making our team a bottleneck
• Strengthen frontend infrastructure in CI/CD, including build, test, lint, packaging, and other workflows that help engineers ship with confidence
• Make accessibility a built-in capability through accessible component APIs, shared guidance, automated checks, and close partnership with product teams
• Own or contribute to cross-cutting frontend capabilities that need to work consistently across applications and teams
• Partner with product engineers, designers, product managers, and other platform teams to understand their needs, make durable technical decisions, and drive adoption of shared solutions
• Lead projects from problem definition through implementation, rollout, documentation, and iteration based on feedback from platform customers
• Raise the bar for frontend engineering through design reviews, code reviews, technical writing, mentoring, and knowledge sharing
