## Description

Profound is the fastest-growing AI marketing platform, used by 15% of the Fortune 500 including Comcast, Estée Lauder, and Walmart, and innovators like Ramp, MongoDB, and Figma. It is where marketing teams do the work: research, briefs, content, campaigns, reporting, all in one place, alongside agents that carry the load with them.  

Built on 2B+ real user prompts and growing, Profound’s data shows you what people ask AI and what the models say back. Profound's AI Marketer joins that data with deep context about our customers to find the opportunities worth acting on, and then puts agents to work: automating reporting, drafting content, auditing pages for readability, running competitive research. It measures what works and gets better every day.

As a Post-Training Engineer, you will turn Profound’s proprietary answer-engine data into models that are measurably better at the work our customers rely on: analyzing AI visibility, attributing citations, classifying sentiment, verifying claims, using tools, and running long-horizon agentic workflows. Most post-training is measured against benchmarks. Ours is measured by whether a Fortune 500 marketing team gets the right answer. You’ll own the full loop, from dataset to reward design to training run to deployment, then watch how your model performs with real customers and feed that into the next cycle.

What you’ll do

 - Turn Profound’s answer-engine data (prompts, responses, citations, query fanouts) into high-quality training datasets

 - Build and iterate on SFT, preference optimization, and RL pipelines

 - Design reward
