Cyber RF Engineer

Woburn, MA

STR’s Cyber Division is hiring a Cyber RF Engineer who will leverage their RF and Signal Processing skills as part of multi-disciplinary teams engaged in solving unique cybersecurity problems. Candidates must be comfortable applying RF principles and techniques to perform analysis and characterization across a diverse set of cyber physical systems. Candidates should have a solid understanding of RF phenomenology to support theoretical analysis, modeling, and hardware experimentation in order to rapidly prototype solutions encompassing hardware and software/firmware components.

We are seeking candidates with previous experience working with both Commercial-Off-The-Shelf (COTS) and custom RF hardware components for development of experimental systems that enable RF-enabled cyber instrumentation and capabilities. Successful candidates will develop solutions in a collaborative, team environment resulting in quality output products with support for future reuse.

What you will do:

  • Perform RF-related signal processing analyses to formulate relevant transmission waveforms and sensing techniques (e.g., side channels) for cyber physical systems
  • Develop rapid prototype RF solutions to go from free space to bits using a combination of COTS and custom designs
  • Conduct system trade studies and analyses to evaluate proposed hardware architectures
  • Conduct lab-based acquisitions and field testing to collect and analyze characterization data for cyber physical systems of interest
  • Collaborate as part of a multi-disciplinary cybersecurity investigative team
  • Support proposal efforts by providing input on technical development paths and BOM/cost and schedule estimates.

Who you are:

  • This position requires an active Top Secret (TS) security clearance, for which U.S. citizenship is needed by U.S. Government
  • BS in Physics, Electrical Engineering, or related field with 5 years of related experience OR a MS and 3 years OR a PhD
  • Strong RF design or implementation background with experience in system analysis and component characterization
  • Experience working with RF components (antennas, power amplifiers, low noise amplifiers, filters, mixers, etc.)
  • Knowledge of digital signal processing and time/frequency domain analysis
  • Strong problem-solving skills and willingness to mentor junior engineering staff
  • Proficiency in MATLAB, Python, C/C++, or other programming languages.
  • Experience preparing/presenting technical material to customers and internal staff
  • Proven experience leading from concept to implementation managing cost and scheduling requirements

Nice to haves:

  • Experience in a laboratory environment utilizing test equipment (oscilloscopes, spectrum analyzers, VNAs, etc.) to characterize cyber physical systems
  • Experience with field work, preparing and executing test events for customers
  • Familiarity with EM Field Solvers (e.g., ANSYS HFSS, Sonnet)
  • Design experience with antennas, RF PCBs, RF ICs, and RF transceiver building blocks
  • Knowledge of mechanical design, digital signal processing, and RF propagation effects
  • Experience with digital electronics buses and FPGA hardware designs
  • Experience integrating software defined radios and RFSOC platforms
  • Experience with electronics, digital circuits and communications protocols (op-amps, PCB analysis, i2c, SPI, etc)
  • Knowledge of computer networking and the TCP/IP stack
  • Practical experience with RF systems (e.g. radar, communications systems)
  • Multi-disciplinary experience in computer science, computer networking, computer architectures, cybersecurity, RF data transmission

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Form CC-305

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
