• High-ownership environment solving "impossible" engineering problems for high-scale production environments.

What you will do

• Architect and build the core alert, investigation, and root cause analysis pipeline using Python and multi-agentic orchestration.
• Design critical systems for alert ingestion, hypothesis orchestration, and investigation execution runtime.
• Partner with founders to set the technical bar and drive architecture decisions for observability and reliability.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
