Job Description

Join an elite team of former Palantir operators building an AI-native operating system for Fortune 500 enterprises. As a Product Engineer, you will own the end-to-end lifecycle of features that replace complex legacy ERP systems. This role demands a builder's mindset, combining high-quality systems engineering with deep product intuition to deliver production-ready agentic systems.

Why this role is remarkable

• Work at a talent-dense startup founded by Palantir veterans, recently securing a massive $50M Series A from premier investors like Index Ventures and Iconiq.
• Build for real-world impact with Fortune 500 customers like Daimler Truck and Heidelberg Materials already using the platform in production.
• Experience a high-velocity, office-first culture in Fitzrovia, London, with full visa sponsorship and the autonomy to define the company's technical trajectory.
  
  

What You Will Do

• Own the full product lifecycle from initial customer research and requirements gathering to implementation and iterative shipping.
• Design and build sophisticated AI agent harnesses that provide intelligence and freedom while maintaining enterprise-grade governance and reliability.
• Develop full-stack features using a modern stack including React, Kotlin, and Temporal to solve hundreds of millions of dollars in legacy IT complexity.
  
  

The ideal candidate

• Proven track record as a founding or early engineer at an AI-native scaleup or a product-focused role at frontier labs like OpenAI or Anthropic.
• Exceptional engineering fundamentals with the ability to ship functional agentic systems and operate confidently across the entire technical stack.
• Strong product sense and user empathy, with a demonstrable history of building side projects, contributing to OSS, or winning technical hackathons.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
