Job Summary:

The Senior Edge Computing Engineer is a hands-on developer role responsible for the core performance of our fielded systems. You will own critical subsystems, utilizing advanced GPGPU techniques to process high-velocity data streams in real-time. You will work with minimal supervision to architect and implement solutions that run on diverse hardware targets, from multi-GPU rackmount servers to power-constrained embedded modules.

Responsibilities:

• High-Performance Computing: Design and implement high-throughput processing pipelines using Modern C++ and GPU-accelerated frameworks (e.g., CUDA, Holoscan, ROCm).
• Kernel Optimization: Write and optimize custom GPU kernels for signal processing operations, managing memory coalescing and host-to-device data transfers to minimize latency.
• System Profiling: Profile full-stack software performance to identify CPU/GPU bottlenecks, optimizing memory usage and PCIe bandwidth utilization.
• Hardware Abstraction: Design software interfaces that abstract specific hardware peripherals, ensuring our GPU-based algorithms can run on a variety of radio and sensor platforms.
• Edge Infrastructure: Manage the build and deployment pipelines for embedded Linux operating systems, ensuring fielded systems correctly expose accelerator resources to containerized applications.

Requirements:

• Bachelor's Degree in Computer Science or Engineering from an accredited college/university.
• Ability to obtain and maintain a DoD clearance; active clearance preferred
• Proven ability to lead engineering teams in a structured software product development environment
• Strong organizational and technical communication skills, including presenting to internal and government stakeholders
• Four (4) year to seven (7) years of software engineering design experience
• Proven experience leading software engineering teams through full development lifecycle

Preferences:

• Current DoD Top Secret SCI Security Clearance
• Master's Degree in Computer Science or Engineering from an accredited college/university.
• Background in Digital Signal Processing (DSP) or RF systems
• Experience with kernal-bypass networking (DPDK, RDMA) or GPUDirect technologies

Skills:

• Languages: Expert proficiency in Modern C++. Willingness to work with or learn Rust for safety-critical components.
• GPU Frameworks: Proven experience with CUDA or similar parallel computing standards. Ability to reason about heterogeneous memory architectures (Unified Memory, Zero-Copy).
• Infrastructure: Solid experience with Linux system administration, container orchestration (Kubernetes/Docker), and networking configuration.
• Architecture: Experience designing decoupled, modular software components using standard protocols (e.g., gRPC, Protobuf).
