## About the role

As Simulation Engineering Manager, you will lead a focused team of Simulation Engineers and be accountable for the quality, pace, and operational health of Aaru's production simulation system. Managers at Aaru remain engineers. You will set technical direction, review critical designs, write and debug code when needed, inspect model and system failures, hire exceptional engineers, and develop the people on the team.

## What they're looking for

- Two simulations with nominally identical inputs produce materially different outputs. Trace every source of state and randomness, quantify the acceptable variance, and make the result reproducible enough to explain
- Aggregate accuracy improves while performance for an important subgroup deteriorates. Build the diagnostics and release policy that prevent the average from hiding the failure
- A hundred-thousand-agent run is too slow and expensive for the product roadmap. Find the right combination of algorithmic changes, batching, caching, model selection, inference strategy, and approximation without eroding fidelity
- A research workflow works only in one person's notebook. Turn it into a self-serve production path with typed contracts, tests, experiment tracking, guardrails, monitoring, and rollback
- Product Engineering needs a new simulation interaction that violates assumptions in the existing engine. Decide whether to extend the core abstraction, introduce a separate mode, or change the product design
- An incident cannot be attributed because the relevant model, prompt, data, and population versions were not captured. Fix the immediate problem and redesign the system so the class of failure cannot remain invisible
