We are seeking a forward-leaning High Compute Engineer to lead the design, optimization, and integration of GPU-centric high-performance compute environments. The ideal candidate will be responsible for managing existing NVIDIA A100 and DGX-1 systems while designing scalable architectures to incorporate emerging GPU hardware as mission demands evolve.

This role is critical to our advanced compute initiatives, where performance, stability, and future-readiness drive every architectural decision. You'll work cross-functionally with data scientists, AI/ML developers, cybersecurity experts, and infrastructure teams to create a robust, secure, and performant GPU compute ecosystem.

This is a 100% on-site position. All work must be performed at the customer site in Bethesda at the Intelligence Community Campus.

Responsibilities:

• Manage, optimize, and monitor existing high-performance GPU systems including NVIDIA A100s and DGX-1 platforms.
• Architect integration plans for scaling GPU compute infrastructure, including newer platforms (e.g., H100, Grace Hopper, AMD Instinct).
• Collaborate with data science teams to fine-tune GPU workloads for AI/ML pipelines.
• Design and implement high-speed networking (InfiniBand/RDMA) and storage solutions optimized for GPU data flow.
• Develop automation workflows using infrastructure-as-code (IaC) tools (e.g., Ansible, Terraform, SaltStack).
• Ensure system security, compliance, and patch management in alignment with NIST, RMF, or agency-specific controls.
• Analyze compute performance metrics and provide strategic recommendations for system enhancements.
• Maintain documentation on system architectures, configurations, and operational procedures.

You Bring

• Bachelor's or higher degree in Computer Engineering, Computer Science, or a related field with at least 12 years of related technical experience. Additional years of experience may be considered in lieu of a degree.
• 5+ years experience supporting GPU compute environments in mission-critical or enterprise settings.
• Proficiency with NVIDIA technologies: A100, DGX-1, CUDA, cuDNN, NCCL.
• Strong background in Linux (RHEL/CentOS/Ubuntu), kernel tuning, and HPC stack deployment.
• Experience with containerized GPU workloads using Docker, Kubernetes, and NVIDIA GPU Operator.
• Familiarity with distributed compute frameworks (e.g., SLURM, Kubernetes, Ray).
• Strong scripting skills: Bash, Python, or similar.
• Proven ability to plan and execute large-scale system upgrades and migrations.
• Candidate must, at a minimum, meet DoD 8570.11- IAT Level II certification requirements (currently Security+ CE, CCNA-Security, GICSP, GSEC, or SSCP along with an appropriate computing environment (CE) certification). An IAT Level III certification would also be acceptable (CASP+, CCNP Security, CISA, CISSP, GCED, GCIH, CCSP).

Clearance

• Active TS/SCI clearance with Polygraph required OR active TS/SCI and willingness to obtain and maintain a Poly.
• ship is required due to the nature of the government contracts we support.

Preferred Qualifications

• Experience with hybrid cloud GPU environments (AWS, Google Cloud Platform, or Azure with NVIDIA support).
• Familiarity with AI/ML tooling such as PyTorch, TensorFlow, ONNX, and RAPIDS.
• Experience integrating GPUs with storage systems (e.g., Lustre, BeeGFS, Ceph).
• Exposure to hardware acceleration platforms (e.g., FPGA, custom ASIC).

Why Join Us

• Shape the future of high-performance computing within a cutting-edge technical team.
• Influence procurement and system design decisions for future GPU investments.
• Work alongside industry leaders in machine learning, cyber operations, and advanced analytics.
• Access to premier NVIDIA hardware in real production environments.
