VP R&D

We’re a fast-growing AI Personalization startup working with leading brands in Israel and the US, backed by a16z and top Silicon Valley VCs.

Our platform helps eCommerce brands uncover conversion leaks, run AI-suggested experiments, and deliver personalized, optimized experiences in real time.

We’re looking for a VP R&D to join the founding team and help shape the product, architecture, and engineering culture from an early stage.

This is a deeply hands-on role. We are looking for someone who is highly motivated by technology, still loves building, and wants to stay close to the code, architecture, product, and technical decisions.

At the same time, this role is intended to grow into a broader R&D leadership position as the company scales. We’re looking for someone with a proven management track record, ideally someone who has previously been promoted into engineering leadership and managed development teams — preferably at least at group manager level or equivalent.

The right person combines strong technical depth, product intuition, high ownership, and real leadership ability.

What You’ll Do

• Design, build, and ship core product features end-to-end
• Build agents, tools, skills, harnesses, and scalable agentic workflows
• Make architectural decisions across frontend, backend, data, and infrastructure

• Build scalable, reliable systems that operate in high-traffic production environments
• Develop systems for real-time personalization, experimentation, and optimization
• Balance fast iteration with robustness, performance, and long-term maintainability

• Experience working with large-scale data, event streams, analytics, or high-volume datasets
• Strong understanding of browser runtime behavior, JavaScript execution, DOM, performance, security, and edge cases
• Solid fundamentals in system design, APIs, data modeling, infrastructure, and performance
• Comfortable operating in ambiguity and making high-impact technical decisions
