Job Description

Founding engineer role at a stealth-style startup in NYC. You’ll be one of the first engineers, working directly with the founders across the stack: agents, low-level systems, ML infra, and the runtime that ties it together. Expect hard, high-leverage problems and a high-ownership environment. You’ll contribute to building a Python/Rust/TypeScript stack that enables autonomous execution of experiments and interaction with scientific instrumentation. Strong generalists who have shipped real systems and are comfortable in messy, low-level territory are a good fit. Bonus: ML/agents, scientific instrumentation, or industrial automation. This is onsite in NYC and compensation includes base salary plus equity. To apply, email contact@tetherline.dev with a bit about yourself and something you’ve built you’re proud of.
