Job Description:

Description Company Description: Altamira Technologies has a long and successful history providing innovative solutions throughout the U.S. National Security community. Headquartered in McLean, Virginia, Altamira serves the defense, intelligence and homeland security communities worldwide by focusing on creating innovative solutions leveraging common standards in architecture, data and security. Altamira believes that our people and the culture of our company differentiate us from other companies. 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 Signal Processing (DSP) , and real-time data orchestration. While you'll collaborate with hardware teams and GUI teams, your domain is the software stack: from socket-level data ingestion in C/C++ to signal processing and automation in Python to interface development in Java . We are specifically looking for candidates with experience in signal processing frameworks. 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 DSP 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. Software-Defined DSP : Translate complex mathematical algorithms (FFTs, FIR filters, DDC, spectral estimation) into efficient, scalable software implementations. Data Orchestration: Develop software to handle high-rate data streams over UDP/TCP , ensuring packet integrity and low-latency transfer between hardware and software. System Integration: Build and manage the software "glue" that interfaces with specialized hardware. Automation & Tooling : Create Python-based tools for automated testing, signal simulation, and performance benchmarking of the software stack. Develop gitlab CI integration for automated build and deployments. Agile Collaboration: Lead code reviews, utilize Git and Jira to manage complex software releases in a collaborative environment. Qualifications and Experience: Core Engineering: 3 years of professional software development experience with a heavy emphasis on C/C++ and Python . Linux Systems: Deep proficiency in Linux environments, including multi-threading, IPC (Inter-Process Communication), and network socket programming. Frameworks: Direct experience with X-Midas or similar signal processing frameworks (e.g., GNU Radio, REDHAWK). Mathematical Computing: Experience implementing mathematical / scientific algorithms in code. Software Best Practices: Strong grasp of Object-Oriented Design, design patterns, and modern DevOps/CI/CD workflows. Signal Experience: Familiarity with electronic signal characteristics (pulsed/CW radar, modulations) to inform software algorithm design. Nice-To-Have Qualifications: Experience with CUDA or OpenCL for GPU-accelerated signal processing. Knowledge of containerization ( Docker/Podman ) and orchestration for deploying processing nodes. DSP Knowledge: Solid understanding of Digital Signal Processing concepts and their software implementation (experience with NumPy, SciPy, or FFTW is a plus). Familiarity with modern C++ standards (C++17/20). Background in Electronic Warfare (EW) , SIGINT (COMINT, ELINT). Work Location: Warrenton, VA. Clearance Requirements: Must be a U.S. citizen and have a TS clearance / SCI preferred. Application Guidance: Please submit your resume and a portfolio or cover letter highlighting your experience in C++/Python systems and any specific signal processing or scientific / mathematical computing projects you have been involved with. Altamira is an Equal Opportunity/Affirmative Action employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or protected veteran status. We focus on recruiting talented, self-motivated employees that find a way to get things done. Join our team of experts as we engineer national security!
