Machine Learning Engineer (LLM & AI Agents)

Seamflow is removing one of the last major barriers to progress in the physical world. While software evolves rapidly, industries like aerospace, healthcare, and energy are still constrained by outdated, manual systems — and we’re changing that.

We’re a fast-growing stealth startup with six-figure revenue achieved in just three months and a $4.5M seed round raised at 14× oversubscription from Tier 1 investors including Coinbase, Reddit, Klarna, and Spotify. This is a rare opportunity to help define how new ideas move from concept to reality, moving fast and executing without compromise.
