About The Position

The Wireless Protocol Analysis Lab is looking for a new team member passionate about building the next generation of software-defined protocol processing frameworks and applications. Our team of approximately 20 engineers comprises a mix of digital signal processing experts, large-scale application developers, and wireless protocol experts who work together to create some of the most highly optimized, software-based, platform-independent protocol processing engines in the world. Our solutions, refined and advanced over two decades of development, allow for a mix of deployment options, ranging from low-power embedded SBCs to multi-core computing clusters with FPGA and GPU capabilities. More About the Role: Define, design, implement, and test components of wireless protocol stacks, ranging from physical layer algorithms to layer 2/layer 3 procedures Contribute to systems-level engineering discussions that reconcile the various use cases for our software in pursuit of best-in-class solutions Work with customers (both internal and external to CACI) to help integrate our solutions into a wide variety of applications and use cases Debug, test, and validate our capabilities using both unit tests as well as scenarios reported by our end users Travel to other CACI locations and/or customer sites in the US as necessary (travel requirement is typically 0 - 15%)

Requirements

A drive to continuously improve and refine existing capabilities alongside new development opportunities.
Ability to work with a distributed team and manage your time effectively across multiple, simultaneous projects.
A strong understanding of modern C++ programming. We consider C++11 to be the minimum but love to use C++17/20 features where appropriate.
Knowledge of wireless physical layer algorithms and their implementations, or an ability to learn and understand existing implementations.
Code profiling experience, ability to identify critical code paths, and offer performance optimizations based on analysis over multiple scenarios.
Experience using wireless test equipment in lab environments, including test setup design.
A bachelor’s degree (or higher) in Computer Science or Electrical Engineering or equivalent technical degree or an additional 4+ years of experience in lieu of degree.
5+ years of related experience
Experience writing software for Linux-based operating systems
C/C++ programming experience, shown through project work or code examples
Demonstrated ability to read and understand technical specifications, and create software-based implementations of the procedures and methods described therein
Excellent communication and interpersonal skills
The ability to obtain and maintain and US Government Clearance at the TS/SCI level.
Previous experience with wireless protocols (e.g., 3GPP cellular protocols, IEEE wireless standards, and/or ITU/ETSI-defined mobile radio standards).
