Senior Frontend Engineer, Handshake AI Enterprise

For cash compensation, we set standard ranges for all U.S.-based roles based on function, level, and geographic location, benchmarked against similar stage growth companies. In order to be compliant with local legislation, as well as to provide greater transparency to candidates, we share salary ranges on all job postings regardless of desired hiring location. Final offer amounts are determined by multiple factors, including geographic location as well as candidate experience and expertise, and may vary from the amounts listed above., Handshake AI Enterprise is a new business unit building AI-powered applications for the world’s largest companies. We deploy small, expert teams directly into enterprise environments - deeply learning each customer’s business, defining where AI can drive real impact, and building and iterating on agents that automate their most critical workflows. We’re not a consulting firm and we’re not selling software. We’re building and deploying AI that measurably changes how enterprises operate., As our first senior frontend hire, you’ll define how we build UI across the entire team. That means establishing the component system, design language, and engineering patterns that every engineer who comes after you will rely on. You’ll set the technical bar, make the foundational decisions, and build in a way that scales - so others can move fast without sacrificing quality.

This is a rare opportunity to own the frontend architecture of a new product from zero, at a company with the data, lab relationships, and momentum to win., * Architect the frontend foundation for Handshake AI Enterprise - component system, design tokens, patterns, and engineering conventions that the whole team builds on

• 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

• 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

Extra Credit
