About the Role: As the Software Engineer, GTM at Halcyon Labs , you will reimagine how our Go-To-Market organization operates by building the systems, tools, and workflows that power it.

You will partner directly with our Lead Engineer for Special Projects to solve problems and ship quickly. At Halcyon Labs , AI is embedded in how we build. You will use AI as a core part of your development process, moving rapidly from idea to prototype to production and pushing tools like Claude, Cursor, and Codex to their limits.
