About the Role
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.
We're looking for a Senior Frontend Engineer who wants to architect the foundation - not just build on top of it.
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.
Location: San Francisco, CA | 5 days/week in-office
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
Desired Capabilities
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
Experience building frontend architecture for AI-powered or data-intensive applications
Background at a company known for high craft - you've seen what a great design system looks like from the inside
History of writing technical documentation or guides that helped other engineers ramp quickly
Experience with performance optimization, accessibility standards, or cross-platform rendering at scale
Familiarity with enterprise deployment environments or security constraints
