THE OPPORTUNITY

## A role wortha closer look.

Use ML infrastructure experience to develop and assess technical tasks for frontier-model training. The work centres on kernels, accelerator diagnostics and inference performance, including evaluation rubrics and written solutions. This is an expert training-and-evaluation engagement, rather than a promise to operate a lab's production serving stack.

### Experience highlighted by the employer

- At least two years in ML infrastructure, accelerator performance or model serving; practical depth in at least one listed systems area.
- JAX or PyTorch experience, clear technical writing and availability for 40 weekday hours without conflicting engagements.

### Location & eligibility

The description explicitly permits worldwide remote candidates, with engagement through Cincinnatus or a local employer-of-record partner. Country availability and authorization still need confirmation. The header says hourly contract; the body describes a full-time engagement and generic contractor terms. Confirm the actual agreement, exclusivity and hours. The source says it cannot support H1-B or STEM OPT candidates.

### Compensation

$90–$120 / hour · Confirm currency. Published source range uses a dollar sign without naming the currency. This is not a guaranteed offer; confirm currency and country-specific engagement terms.
