Rox is building the AI-native revenue operating system for modern go-to-market teams. Backed by Sequoia, GV, and General Catalyst, we’re working with some of the most ambitious enterprise teams to replace fragmented CRM workflows with intelligent, autonomous systems. Rox connects data across the GTM stack, deploys AI agents to do real work, and gives revenue leaders a clear, shared picture of what actually drives outcomes.
We’re a small, fast-moving Series A team taking on one of software’s most entrenched categories — and we’re winning by combining deep technical rigor with obsessive focus on usefulness.
Engineering at Rox is product-first and execution-driven. We build real systems used daily by revenue teams operating at scale, which means every architectural decision — frontend, middle-tier, or backend — has direct customer impact.
Product Engineers at Rox are not siloed. While roles have clear areas of strength, engineers are expected to understand how the entire system fits together: how UI state maps to APIs, how frontend decisions affect backend load, and how product experiences scale as customers grow.
This is a Product Engineer role for someone who is truly expert in React and deeply opinionated about frontend quality, architecture, and user experience.
You will own large portions of the product surface area — building complex React interfaces, shaping frontend architecture, and implementing the middle-tier logic that connects UI experiences to backend systems. While this is not a backend-heavy role, you are expected to understand backend design, integration patterns, and scalability tradeoffs well enough to build clean, durable systems end-to-end.
If React isn’t your strongest skill, this role is not a fit.
Build and evolve complex, production-grade user interfaces using React as the primary framework
Own frontend architecture decisions including component design, state management, data flow, and performance
Implement middle-tier logic that connects frontend experiences to backend services and data systems
Collaborate closely with backend and platform engineers to design clean APIs, integrations, and system boundaries
Participate in technical design discussions spanning frontend architecture, backend integration, and scalability
Ship end-to-end product features with a high bar for quality, clarity, and maintainability
In your first few weeks: You’re productive in the codebase and contributing meaningfully to frontend features
Within a few months: You own major areas of the UI and influence frontend architecture decisions
Over time: You raise the bar for frontend quality while helping the team build systems that scale cleanly across the stack
Expert-level experience with React
Deep understanding of component architecture, hooks, state management, rendering behavior, and performance
Experience building and maintaining large, production React applications
Strong frontend engineering fundamentals
UI architecture, client-side data flow, performance optimization, and browser behavior
High bar for code quality, maintainability, and user experience
Solid middle-tier and backend awareness
Comfort implementing business logic and API orchestration layers
Working understanding of backend system design, data models, and integration patterns
Ability to reason about scalability, reliability, and system tradeoffs
Experience with Next.js and/or TypeScript in production environments (strongly preferred)
Rox’s product is only as good as the systems behind it — and the frontend is where customers feel that quality first. This role exists to ensure we have engineers who can own that experience end-to-end: from React architecture to backend integration, without sacrificing performance, clarity, or scalability.
If you want to build real product, operate with high ownership, and work at the intersection of frontend excellence and system design, this role will give you both the scope and the impact.
