  • Optimize and track performance metrics of our simulations 
  • Maximize parallelism and caching in our build systems and services 
  • Develop QA frameworks and maintain high reliability standards 
  • Provide feedback and guidance on code reviews and design reviews 
  • Sustain our internal and external documentation 
  • Lead team-wide discussions and research as we continue to innovate on the semantics and implementation of our simulation technology
