“You’d own the post-training specialty beside the solutions architects.”
Who it suits
A good fit
- Have run fine-tuning or reinforcement learning on a real model
- Like designing the experiment and the evaluation rather than only running the training job
- Want to size the compute with sales and capacity
Think twice
- Want to be the solutions architect rather than the post-training specialist
- Haven’t diagnosed a training run that went wrong
- Don’t want to run a customer proof of concept
What you’d do
- Help customers set their data strategy for post-training and diagnose data that limits quality.
- Recommend the post-training approach, design the experiments, and catch instabilities and reward hacking.
- Build evaluation with the customer, including task benchmarks and held-out tests.
- Size reinforcement learning and fine-tuning workloads with the sales and capacity teams.
What they ask for
- You can guide a customer through data, algorithms, experiment design, and evaluation.
- You can tell when a training run is unstable or a reward is being gamed.
- You can choose a base model and a baseline before the post-training starts.
- You have 5 or more years in a technical ML role, with recent hands-on post-training and production Python.
How it works
- Together AI offers remote flexibility, and it doesn’t say how many days are in the office or on site with a customer.
