  • Be a founding member, directly shaping the core architecture of next-generation autonomous agents

  • Backed by top-tier VCs, combining early-stage impact with funding stability

  • Innovate beyond standard RAG on unsolved problems in multi-stage retrieval and synthetic world models

What you will do:

  • Design and scale foundational long-horizon memory and knowledge infrastructure for agents to reason over evolving enterprise contexts

  • Develop state-of-the-art search and retriever systems using novel indexing techniques and knowledge representations

  • Apply deep expertise in reinforcement learning and reasoning to guide agentic behavior in complex, multi-step tasks

The ideal candidate:

  • World-class expertise in search, retrieval, or reinforcement learning with applied research experience in production systems

  • Strong engineering fundamentals to build robust, enterprise-grade systems capable of scaling to trillion-agent interactions

  • Thrives in high-autonomy environments and is motivated to define foundational technologies for enterprise-level agentic superintelligence

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Step 5. If Jill thinks you're a great fit and her client wants to meet you, they will make the introduction
Step 6. If not, Jack will find you excellent alternatives. All for free

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.
