Senior Go Engineer, Execution Engine

You will work on the scheduler, the run lifecycle, and the durability layer: the part of GoRunner that makes 'ultra-fast' a measurable claim instead of a slogan.

What you will do

• Design and ship improvements to the in-process scheduler and its crash-recovery story
• Own performance: profiling, benchmarks, and the public methodology we publish
• Build the primitives behind retries, timeouts, and human-approval steps
• Review designs across the engine team and raise the bar kindly

What we hope you bring

• Deep, production Go experience: you have opinions about goroutine lifecycles and can defend them
• You have operated stateful systems under real load and have the scars
• You write clearly; design docs here are short and load-bearing
• You would rather delete code than abstract it
