What is a signal security?

A Signal Security job involves protecting military or organizational communication systems from interception, jamming, or unauthorized access. Personnel in this role monitor and analyze signals, implement encryption protocols, and ensure secure transmission of sensitive information. They work to detect potential threats and vulnerabilities in communication systems. This job is critical in maintaining operational security and preventing adversaries from gaining intelligence through signal interception.

What are the typical daily responsibilities of a signal security professional?

Professionals in Signal Security are responsible for monitoring and analyzing communication channels for potential security breaches, maintaining and configuring secure communication devices, and implementing encryption protocols to safeguard sensitive information. They may also conduct vulnerability assessments, manage access controls, and train team members on best practices. Daily work often involves collaborating with IT, cybersecurity, and operations teams to ensure secure data transmission across networks. These responsibilities are crucial for maintaining organizational security and compliance with relevant regulations.

What are the key skills and qualifications needed to thrive in signal security?

To thrive in Signal Security, you need expertise in communication protocols, cryptography, electronic surveillance, and information assurance, often supported by relevant degrees and military or security clearances. Familiarity with secure communication systems, signal jamming devices, encryption/decryption tools, and certifications such as CompTIA Security+ or CISSP is highly valued. Strong attention to detail, analytical thinking, and the ability to work discreetly and collaboratively are important soft skills. These abilities are critical for protecting sensitive information, preventing unauthorized access, and maintaining secure communications in high-stakes environments.

Job description

About the Team:
The Sensors Division at STR focuses on technology development for advanced sensor systems to add national security capabilities, particularly in the areas of airborne/surface-based radar, electronic warfare, underwater acoustics, hyperspectral imaging, and EO/IR sensing. Within these areas, we perform work on emerging concepts & technologies, component & system development and prototyping, and experimental campaigns.
The Optical & Novel Sensing (ONS) Group within the Sensors Division pursues physics-driven research across multiple domains to provide warfighter and intelligence mission performance unachievable with traditional sensors. Our main customer focus is on Department of War and Intelligence Community research and development programs, with work spanning concept formulation through validation prototyping.
The Role:
As a Senior Algorithm & Signal Processing Researcher, you will develop and apply state-of-the-art algorithms and techniques for HF communications that include signal detection, channel equalization, and geolocation. You'll have opportunities to engage directly with our customers to communicate technical analyses for their most critical challenges. You'll work with a team of researchers in creating innovative system capability and collaborate with the engineering team to develop and demonstrate and optimize system capabilities.
A successful candidate will have demonstrated strong analysis skills and expertise in several of the following areas: adaptive signal processing, equalization, High Frequency (HF) radio propagation, ionospheric physics, machine learning, algorithm development, algorithm integration, test & evaluation, model & simulation, systems engineering, or communications systems. They will apply first principles of physics to model and simulate realistic environments to support system performance modeling at HF radio frequencies to develop realistic simulations of complex propagation environments. This position requires skills contributing to a multi-disciplinary team designing, analyzing, integrating, and demonstrating signal processing algorithms for complex systems.
What you will Do:
  • Work closely with program leadership to spearhead efforts that align with program and company priorities
  • Apply cutting-edge signal processing techniques to solve complex HF propagation challenges for critical national security missions
  • Collaborate with diverse teams, learning from the different perspectives to develop and deploy prototype systems that demonstrate our ability to extend the boundaries of what's possible
  • Document and present products to a community of scientists and subject matter experts

Who You Are:
  • Ability to obtain a Top Secret security clearance, for which U.S. citizenship is needed by U.S. Government.
  • PhD, MS, or BS in Electrical Engineering, Applied Mathematics, Physics, or related technical discipline
  • 3+ years of experience on RF programs, including the development of advanced signal- and data-processing algorithms from mathematical/analytical derivation through testing and verification of system performance
  • Experience in two or more of the following areas: RF signal processing, HF propagation (or propagation in dispersive, heterogeneous media), adaptive signal processing, algorithm development, system model & simulation, and geolocation
  • Excellent communicator with ability to develop and tailor technical briefs to influence a range of technical and non-technical audiences
  • Proficiency in one or more scientific or mathematical programming languages, such as MATLAB, Python, and C/C++
  • Strong mathematical, troubleshooting, written, and verbal communication skills

Even Better:
  • Active Top Secret Clearance
  • Demonstrated ownership of complex research, development, and engineering efforts
  • Advanced degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline
  • Experience with HF propagation modes and an understanding of the underlying physics, end-to-end signal processing chain
  • Ability to apply novel, innovative and interdisciplinary approaches to challenging engineering problems
