What You’ll Own Architect scalable simulation APIs in Java, C++, or Python . Bridge on-prem HPC clusters to AWS via Kubernetes and Terraform.

Build high-throughput data caching and storage layers. Optimize Linux systems and network performance for zero downtime. What You Bring Solid backend depth in Java, C++, or Python and distributed systems.

Hands-on AWS, Kubernetes, and Terraform experience. Low-level Linux troubleshooting skills (CPU, memory, network I/O). End-to-end product ownership from design to production.

Bonus Points Prior exposure to HPC workload schedulers (Slurm, PBS), high-speed interconnects (Infini

Band/RDMA), or large-scale scientific modeling platforms. If you care about memory layout, network topology, and raw compute performance, let’s talk.
