Senior Applied ML Engineer, Evals & Data

Experience shipping and operating an LLM or agent system used by real customers.

Strong software engineering skills in TypeScript or Python, with the ability to work across both.

Experience building evaluations, datasets, experiments, or AI quality systems.

Strong product judgment and the ability to turn unclear quality problems into measurable improvements.

You do not need a PhD or experience training foundation models. Evidence of building reliable AI products matters more than formal credentials or knowledge of a specific framework.

Experience with multimodal AI, video, media, or creative software.

Experience with human labeling, model graders, or fine-tuning.

Good knowledge of experiment design and statistics.

We have a trusted quality baseline for our main agent workflows.

Production failures regularly become new evaluation cases.

Important agent changes pass clear regression checks before release.

We can show measurable improvements in key editing workflows.

You'd be surrounded by people who are absurdly good at what they do. One started coding at 11 and shipped an app with 6M+ downloads in high school. One got into CS engineering at 14 and has been working on distributed systems for 8+ years. One's an ex-founder who took a company to 1.2M users and $300M+ in transactions. That's the team. We're looking for someone who'll raise the bar on technical craftsmanship and creative product quality. Apart from that you'd get:

Competitive salary and founding-team equity.

Unlimited tokens across every AI model. Use whatever you want, as much as you want.

A healthy budget for AI tools and any peripherals you need to do your best work.
