Frontend Developer
Join Bay and help secure the next wave of work, where AI agents write code and act on company data alongside the people who use them. Bay is the AI agent security platform that gives enterprises visibility into every agent across devices, browsers and cloud workloads, and control over what those agents do in real time. That way, security teams can back AI adoption instead of slowing it down.
The role
We’re looking for a Frontend Developer to own the Bay dashboard, where CISOs and security teams see every AI agent in their company, understand its risk and decide what it may do. You’ll turn dense, fast-changing security data into an interface people can trust at a glance, and you’ll set the bar for our frontend architecture and design system.
What you’ll do
- Build and own core product experiences in React and TypeScript: agent inventories, entity graphs, activity timelines, findings, policy editors and multi-tenant admin.
- Lead our design system and component library, working closely with our product designer.
- Make large datasets feel instant with virtualization, pagination, filtering and smart data fetching (GraphQL or REST).
- Visualize complex relationships, such as graphs, timelines and prompt-to-action chains, so a security analyst understands an incident in seconds.
- Own frontend quality and infrastructure: TypeScript strictness, linting, unit and E2E tests, performance and CI.
- Work across the stack when needed, shaping APIs together with backend engineers.
What we’re looking for
- 5+ years of frontend development, building complex, data-heavy web applications in production.
- Deep expertise in React and TypeScript, and modern state and data-fetching patterns.
- Strong product and UX sense: you care how things look and feel, not only how they work.
- Experience building or maintaining a component library or design system.
- Comfort with testing (unit and E2E) and frontend performance optimization.
- Daily, practical use of AI coding tools (Claude Code, Cursor or similar).
- Strong communication in English and Hebrew.
Nice to have
- Experience with B2B SaaS dashboards, ideally in cybersecurity.
- Data visualization experience (D3, graph or timeline libraries).
- GraphQL or Relay experience.
- Some backend experience (Node.js, PostgreSQL).
- Experience leading frontend infrastructure or mentoring other developers.
Why join Bay
- Build a new category of AI agent security from the ground floor, with enterprise customers including Micron Technology, Peloton and ClickUp already live.
- Own the product’s face: the dashboard is what customers see, demo and buy.
- Work with a senior team of engineers who have built and scaled security products before.
- Competitive salary and meaningful equity in a well-funded, Series A stage company.
