About the role

Key responsibilities & impact
  • Design and implement scalable solutions for Flexcompute's advanced electromagnetic simulation platform
  • Contribute to API unification, simulation data management including caching, syncing, and storage, and scripting improvements
  • Collaborate with EM and infrastructure teams on simulation-specific solutions
  • Enhance back-end and scheduler integrations and Python front-end functionality
  • Improve task pipelines through web API design for multi-physical simulations
  • Develop and maintain hybrid cloud compute and storage solutions integrating on-premise HPC systems with modern cloud platforms
  • Optimize and manage high-performance computing clusters with high-speed interconnects
  • Own platform components end to end with limited direction and direct access to founders
  • Architect and deploy infrastructure for distributed simulation workloads across cloud and on-premise compute
  • Design scalable web APIs for simulation job orchestration and data access
  • Build CI/CD pipelines and infrastructure-as-code systems for reproducible deployments
  • Develop hybrid cloud solutions connecting on-premise HPC clusters with AWS compute and storage
  • Implement monitoring and observability systems for simulation performance and reliability
  • Improve platform scalability for growing user traffic and compute demand
  • Design secure service architectures, authentication, and licensing systems
  • Optimize infrastructure utilization across CPU and GPU resources

Requirements

What you’ll need
  • Strong backend engineering in at least one of Java, Python or C++; deep expertise in one is sufficient
