Senior DSP Software Engineer

We are seeking a Senior DSP Software Engineer to join a small, high-impact embedded software team at a product development company specializing in advanced spectrum monitoring solutions. These platforms serve both defense applications and commercial spectrum monitoring and transmitting organizations.

This role bridges RF/spectrum domain knowledge with C++ software development on a custom SDR platform. The platform combines Linux-based low-level code and leverages significant FPGA offload (Xilinx Ultra Scale+). This is a hands‑on senior role with opportunities for architecture input, platform‑level development across hardware variants, and direct collaboration with technical leadership.

• Small embedded team (currently 5 engineers; this hire makes
  6).
• Product‑focused company that owns its own IP.
• Platform mix:
  Linux (core/low‑level) + Windows (middleware & applications), with high‑speed 10 Gbps data links from SDR/FPGA to PC.
• New development emphasizes the Linux platform; legacy Windows support continues.
• Strong emphasis on cross‑domain collaboration between FPGA, software, and application teams.

• Collaborate closely with technical leadership to translate high‑level requirements into robust implementations.
• Maintain and enhance a large, mixed legacy + new C++ codebase (Linux and Windows).
• Bridge FPGA/hardware interfaces with higher‑layer middleware and applications.
• Contribute to spectrum/signal processing workflows, including receiver chains.
• Develop platform‑level software supporting multiple hardware variants and applications.
• Build internal test GUIs and tools (limited full application development).
• Provide senior‑level architecture and design input while remaining hands‑on with coding and debugging.

• 6+ Years of Strong production C++ experience
  : proven ability to maintain and enhance large, legacy codebases across Linux and Windows environments.
• Solid understanding of RF/spectrum fundamentals
  , including receiver chains, Digital Down Converters (DDC), ADC metrics/quality, and related signal processing concepts.
• Demonstrated ability to bridge domains
  : interface software with FPGA/hardware (without writing FPGA code) and connect to higher‑layer applications.
• Strong analytical and mathematical aptitude; quick learner comfortable leveraging AI tools for productivity.
• Educational background in Electrical Engineering (EE) preferred (Master’s ideal);
  Physics or Computer Engineering.
• ITAR/government‑related work, so no sponsorship available
