ABOUT ORPEX
The next generation of service companies won't scale through headcount. They'll be built by tiny teams orchestrating AI workforces with 1000x the output. Orpex is building the infrastructure they run on: agentic workforce, company brain, human trust layer, one cockpit to run the business.
We just raised an oversubscribed 2.5M angel round in 7 days and are moving at rapid speed.
APPLIED AI ENGINEER
Everyone is building agents. Almost nobody is building agents a real company can run on.
You own the agentic infrastructure of Orpex: the workforce that executes, the company brain that remembers, and the evals that prove it works. Agents that run the same task for the fiftieth time as reliably as the first. Memory that holds months of client context. Approvals that pull a human in at exactly the right moment. You decide how agents plan, remember, fail and recover. You'll ship to production in your first week.
WHO WE'RE LOOKING FOR
Agents in production. You've shipped LLM agents that ran unattended for real users. You know the model is the easy part.
Evals you trusted. You've built eval harnesses that people actually used to decide what ships.
Memory and context. Retrieval that works on messy operational data, not demo RAG.
Intensity. You force things into existence. Bonus if you've built agent tooling in the open or founded something.
YOUR FIRST MONTH
Ship from day one. An agent running for a real company in week one.
Own the loop. Build it, measure it, break it, fix it, make it learn.
Do what needs doing. Infra, orchestration, customer calls, hiring the next engineer.
WE OFFER
$150–250K USD base + meaningful early equity
San Francisco, in person. Relocation and visa sponsorship covered.
Pace and purpose. Small team, high standards, high trust, no politics.
