Here at Ntaitive, we are hiring a language-agnostic Backend Software Engineer to architect the core engine behind our client's EM massive-scale simulation platform
You will own the compute layer that bridges on-prem High-Performance Computing (HPC) clusters with elastic AWS infrastructure, handling massive, distributed compute workloads where throughput, memory footprint, and low-latency matter.
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 (InfiniBand/RDMA), or large-scale scientific modeling platforms.
If you care about memory layout, network topology, and raw compute performance, let’s talk.
