We work across all simulation products and pipelines, addressing systemic issues, improving release quality, and strengthening the foundations that enable teams to iterate quickly and confidently. Our work spans systems architecture, software engineering, release management, and quality strategy, with a mission to increase reliability, throughput, and operational excellence across the entire simulation ecosystem. Release Management & Quality Strategy Define and drive the simulation-wide quality and test strategy, including shift‑left testing, automated validation, and early‑signal integration. Strengthen release readiness criteria, quality gates, and verification workflows across multiple simulation teams. Improve the performance, stability, and reliability of simulation frameworks and core tooling used at scale. Identify system bottlenecks in the simulation stack and deliver architectural improvements that increase throughput and reduce operational friction. Establish and enforce best practices for simulation incident management, improving resilience, recovery time, and overall operational readiness. Improve signals, metrics, and monitoring patterns that help teams identify release‑related issues earlier and more accurately. Collaborate closely with simulation feature teams, infrastructure groups, and platform stakeholders to align on scaling needs, test coverage gaps, and systemic quality improvements.



Work backward from organizational‑level problems to design solutions that raise simulation quality and reliability across all workflows. Release Engineering & Quality Strategy Experience improving release workflows, verification processes, or quality gates. Ability to spot gaps in test coverage, validation workflows, or release signals and drive systemic improvements. Software Development Strong coding fundamentals with experience building production‑quality services, frameworks, or tools. Background improving reliability, performance, or developer experience in distributed systems. Proficiency in Python and/or C++ Experience with build and release management, including CI/CD Strong software architecture skills, with experience building distributed systems Experience supporting production systems and optimizing performance Experience with release management systems and integration/regression testing Strong hands‑on coding and problem‑solving abilities Experience with incident management.
