Backend Engineer (Architect)

Remote 100% (POLAND) 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.
