Software Engineer - DSP Framework

Infrastructure Engineer - Digital Signal Processing

Join Any Signal to design, optimize, and maintain the core software infrastructure that powers advanced modeling and signal processing development. Any Signal is a startup whose mission is to usher in the next generation of RF products and services for space and defense missions.

Base pay range: $140,000 – $190,000 per year.

What You’ll Do:

• Develop and optimize core modeling frameworks that support high-speed signal processing simulations and analyses
• Modernize existing codebases, translating Python-based functionality into high-performance C/C++ implementations where needed
• Architect reusable, modular libraries that accelerate experimentation and ensure software‑hardware consistency across teams
• Collaborate closely with DSP, firmware, and hardware engineers to ensure modeling tools meet technical and performance needs
• Improve performance and scalability through profiling, multi-threading, and vectorization strategies
• Enhance developer experience by improving tooling for simulation, visualization, and automated testing

Who You Are:

• Strong background in software architecture, systems design, and performance optimization
• Proficiency in Python and C/C++, with experience in numerical or scientific computing libraries (e.g., Num Py, Sci Py, Eigen)
• Understanding of fixed-point arithmetic and hardware-aware software design principles
• Experience with code profiling, optimization, and concurrency (multi-threading, SIMD, or GPU acceleration)
• Prior background owning system framework architecture and cross-team coordination to ensure optimal system architecture integration
• Clear communication skills and ability to collaborate across multi-disciplinary engineering teams

Bonus

Qualifications:

• Experience building or maintaining simulation frameworks or tool chains (e.g., GNU Radio, scientific modeling environments, custom signal‑chain frameworks)
• Familiarity with FPGA development workflows or hardware verification methods
• Experience with network simulation tools such as NS‑3 or similar
• Track record of owning core software infrastructure that enables technical teams to work more efficiently
• Prior experience building around real-time operating systems in a demanding engineering environment
