About the Role
We are looking for an AI Simulation Platform Engineer to join Brex, the AI-powered spend platform. This role involves owning Brexโs simulation and validation platform for AI-powered products, ensuring that every AI surface at Brex is continuously scrutinized under extreme, realistic conditions.
Key Responsibilities
- โEvolve and scale a simulation and validation platform to continuously stress-test Brexโs AI products using large-scale synthetic data.
- โDevelop evaluation mechanisms to detect regressions, edge cases, and failure modes in non-deterministic systems prior to customer impact.
- โRun continuous testing in isolated, production-like environments and set quality gates, including authority to block launches when standards are not met.
- โPartner closely with product engineering teams to improve system testability, isolation, and overall robustness.
- โDefine and uphold company-wide standards for AI feature quality, using simulation-driven insights to guide prompt and system evolution.
Requirements
- โExperience building and owning complex software systems where correctness, reliability, and failure modes are critical.
- โExperience designing test, simulation, or validation systems for non-deterministic or high-stakes environments.
- โStrong systems thinking, with the ability to decompose complex problems and reduce incidental complexity.
- โDemonstrated ability to influence product architecture through quality, reliability, and launch-readiness constraints.
- โComfort operating with real authority and cross-team influence, including blocking launches and partnering across seniority levels to raise the quality bar.
