Product Engineer (React)

At Rox, we believe in empowering people to do their best work.

Our platform supercharges sellers with autonomous revenue agents to do the manual work so they can focus on what they do best: selling. Just as coding agents 10x’d engineering, revenue agents 10x customer work.

We are reimagining the revenue stack by building the world’s first revenue operating system, from the application layer to the system of context. With Rox, humans are evolving to orchestrators while agents manage the end-to-end customer lifecycle.

Rox powers Global 2000 leaders in banking, hardware, construction, and sovereign AI, while serving dominant AI winners like Ramp and Cognition.

Underlying all of this success is an unwavering, shared belief in the mission, with an unreasonable commitment of doing whatever it takes to make it a reality.

Nothing is possible without the world-class team, assembled to redefine how businesses operate.

Members on our team have:

• Founded and exited successful companies

• Held the highest positions at Google, AWS, Confluent, and New Relic

• Won IMO and IOI gold medals

• Published field-defining papers

We’re backed by the best, including Sequoia, General Catalyst, Google Ventures, Elad Gil, and Chris Ré.

No matter how small, we strive to make sure every detail is right. We care deeply about every interaction, both in terms of whether it helps the seller get the job done, but also how the product makes them feel. We get a visceral feeling when something is off and stop at nothing to make sure we make it right. We never settle, continuously exploring ways to delight sellers.

In all aspects of our craft, we commit. We not only are immediately reactive to customers’ requests but are proactive about driving value even before they ask. We are also obsessive about always learning and honing our craft, improving ourselves and product every single day.

Talking is easy but the difference comes from the execution. We lean heavily towards making thoughtful yet fast decisions and delivering immediately. We play in a field where trust is paramount. We earn the trust and right to empower the best sellers by forging a history of over-delivering on the promise at record speed.

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.

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.

• 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)

• Medical, dental, and vision, including 100% company-paid plans for you and eligible dependents

• Company-paid life & AD&D, plus short- and long-term disability

• 401(k) with automatic enrollment

• Unlimited PTO, plus paid sick leave, company holidays, and bereavement

• Up to 20 weeks of paid parental leave at 100% pay (birth, adoption, or foster)

• Wellness stipend: $375/quarter

• Learning stipend: up to $2,000/year

• Internet & cell phone stipend: $25/month

• Mental health support, virtual care, and care navigation

• Fertility & family-building support, plus backup care membership

• Pre-tax commuter benefits (transit & parking)

• SF HQ: daily catered breakfast & lunch, meal allowances, and rideshare support when commuting to the office
