Job DescriptionVacancy Status:No: This posting is not for an existing vacancy within the organization and is open to new applications. (New Head Count)AI Disclosure:As part of the application process, Artificial Intelligence will be used in the hiring process for this roleRemote/Hybrid: candidates can be considered anywhere in the country of work, but if someone is within 80 KM of a hub, they are required to be onsite 3 days a week.About the TeamThe Simulation Scalability team builds the core systems, frameworks, and workflows that ensure simulation runs reliably, efficiently, and at scale. 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.What You’ll DoRelease Management & Quality StrategyLead improvements to the end‑to‑end simulation release process, ensuring it is predictable, well‑defined, and continuously improving.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.Partner with product teams to reduce regressions, shorten validation cycles, and ensure higher-confidence releases.Scalability, Reliability & StabilityImprove the performance, stability,



and reliability of simulation frameworks and core tooling used at scale.Identify systemic bottlenecks in the simulation stack and deliver architectural improvements that increase throughput and reduce operational friction.Enhance simulation exit codes, error attribution, and debugging workflows to improve diagnosability and reduce wasted compute.Operational ExcellenceEstablish 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.Cross-Functional LeadershipCollaborate 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.Who You AreWe’re looking for engineers with depth in at least one of the following areas, and interest in growing across the rest:1. Release Engineering & Quality StrategyExperience improving release workflows, verification processes, or quality gates.Ability to spot gaps in test coverage, validation workflows, or release signals and drive systemic improvements.2. Systems & Solutions ArchitectureAbility to analyze complex simulation or compute workflows and design scalable,



maintainable solutions.Skilled at identifying recurring failure patterns and eliminating systemic causes.3. Software DevelopmentStrong coding fundamentals with experience building production-quality services, frameworks, or tools.Background improving reliability, performance, or developer experience in distributed systems.We welcome candidates who bring robust expertise in one area and are eager to expand into the others.Required Skills:Proficiency in Python and/or C++Experience with build and release management, including CI/CDStrong software architecture skills, with experience building distributed systemsExperience supporting production systems and optimizing performanceExperience with release management systems and integration/regression testingStrong hands-on coding and problem-solving abilitiesExperience with incident management.Compensation:The salary range for this role is $ 115,000 to $ 164,600. The actual base salary a successful candidate will be offered within this range will vary based on factors relevant to the position.GM DOES NOT PROVIDE IMMIGRATION-RELATED SPONSORSHIP FOR THIS ROLE.
