Top Senior C++ Jobs in Washington, DC

Design, implement, and optimize scalable high-performance dense linear algebra kernels for GPUs. Provide technical leadership, collaborate with product and partners, improve performance and quality, and contribute to library roadmaps and development practices.

The researcher/engineer will design and maintain experimental equipment, conduct research in acoustics, and support field tests. Strong hands-on, software, math, and physics skills are necessary. This role may lead to project engineering tasks. The candidate must possess a BS degree or higher, have laboratory experience, and programming skills, while being flexible to handle multiple tasks.

Develop, enhance, and maintain backend web applications and services using C#/.NET. Implement features with ASP.NET, Entity Framework, and SQL Server; write unit and integration tests; perform troubleshooting, code reviews, vulnerability remediation, and O&M tasks while collaborating with senior engineers and cross-functional teams.

Lead development and validation of advanced passive RF geolocation algorithms (TDOA, FDOA, interferometry). Build high-fidelity simulations, implement real-time software on DSP/GPU/FPGA, integrate with RF/SDR hardware, define RF/timing requirements, and support system calibration and field validation. Collaborate across engineering, production, and business teams; travel up to 30% and work on-site multiple days weekly.

Lead development of passive RF geolocation algorithms (TDOA, FDOA, interferometry) from first principles through simulation, real-time implementation, integration, calibration, and field validation. Build high-fidelity simulation environments, quantify performance under real-world impairments, and partner with hardware and systems teams to define RF/timing requirements and support field demonstrations.
