Position: DSP Software Engineer

Location: Warrenton, VA

Position Description We are seeking a Software Engineer who thrives on developing high-throughput data, low-latency code, and complex algorithm implementation. The available position moves beyond high-level application code, focusing on the intersection of systems programming, digital signals processing, and real-time data orchestration. As a Software Engineer at Altamira, you will design and build the software engines that power our sensing and communication platforms. You will be responsible for the full software lifecycle - architecting data pipelines, implementing algorithms in code, and developing robust APIs. You must be comfortable working in a Linux-centric environment where performance optimization and memory management are critical.

Key Responsibilities

• High-Performance Development: Architect and maintain mission-critical applications using C++ for performance-intensive processing and Python for prototyping algorithms, systems logic, data manipulation, and rapid feature deployment.
• Data Orchestration: Develop software to handle high-rate data streams over UDP/TCP, ensuring packet integrity and low-latency transfer between hardware and software.
• Automation & Tooling: Create Python-based tools for automated testing, signal simulation, and benchmarking performance of the software stack. Support GitLab CI integration for automated build and deployments.
• Software-Defined DSP: Translate complex mathematical algorithms (FFTs, FIR filters, DDC, spectral estimation) into efficient, scalable Digital Signal Processing (DSP) software implementations.
• Agile Collaboration: Lead and participate in code reviews, utilize Git and Jira development productivity tools, support complex software releases in a collaborative environment.

Must-Have Qualifications And Experience

• Software Engineering: Professional software development experience with an emphasis on C/C++ and Python.
• Linux Systems: Proficiency with multi-threading, Inter-Process Communication (IPC), and network socket programming.
• Frameworks: Experience with DSP signal processing frameworks (X-Midas, GNU Radio, REDHAWK).
• Mathematical Computing: Experience implementing mathematical / scientific algorithms in code.
• Software Best Practices: Strong rasp of Object-Oriented Design (OOD), design patterns, and modern DevOps/CI/CD.

Nice-To-Have Qualifications And Experience

• CUDA or OpenCL: Experience using GPU-accelerated signal processing.
• Experience with hardware/software integration and networking.
• Docker or Podman: Knowledge of containerization and orchestration for deploying processing nodes.
• Signals: Familiarity with signal characteristics (pulsed/CW radar, modulations) and algorithms (FFTs, FIR filters, DDC).
• Digital Signal Processing (DSP): Understanding of concepts and software implementation (NumPy, SciPy, or FFTW).
• Applications: Background in Electronic Warfare (EW) or SIGINT (COMINT, ELINT) application areas.

Clearance Requirements Must be a U.S. citizen and be able to obtain up to a TS/SCI clearance.

The anticipated salary range for this position is $100,000 to $150,000. Actual compensation will be determined based on several factors, including, but not limited to, the scope of the position, relevant experience, education, certifications, internal equity, customer contractual requirements, security clearance requirements, and other legitimate business considerations.
