With solutions to ensure the efficient use of frequencies, long distance communications, monitoring and security communications intelligence applications, we improve communications and protect military forces and infrastructure around the world.

Sr. Software Defined Radio (SDR) Software Engineer — you will actively participate in the development of radio frequency signal acquisition/processing/storage/retrieval, IQ data transport, direction finding and analysis systems used for spectrum monitoring and communications intelligence purposes. This role applies a strong real time embedded server development background, knowledge of radio frequency communications, reception and signal processing techniques, and software development skills to meet signal detection, parameter measurement and analysis challenges facing spectrum regulators and intelligence organizations globally.

You will develop software to implement architectures using TCI’s existing technical base along with new development to satisfy customer specific and market generic requirements.

While each day brings new opportunities at SPX, your core responsibilities will be:

• Develop a deep understanding of TCI’s Embedded server architectures and become a key contributor to architecting and implementing improvements and new features for our products.
• Modify existing software and/or develop new software to implement improvements or add new features to our systems. Support testing and analysis of new hardware and software performance up to the system level.
• Provide technical support to our product support group by interfacing with customers to deploy new products, solve issues found in the field and to understand potential product improvements.
• Other duties as assigned.

We each bring something to the table, and we are looking for someone who has:
