What is a software defined radio internship?

A Software Defined Radio (SDR) Internship is a program designed for students or recent graduates to gain hands-on experience working with SDR technology. SDR refers to radio communication systems where components that have typically been implemented in hardware are instead implemented by means of software on a computer or embedded system. Interns in this field usually work on projects involving wireless communications, signal processing, and developing or testing SDR platforms. This internship helps participants develop valuable technical skills and gain practical knowledge that can be applied in industries such as telecommunications, defense, and IoT.

What types of projects and technologies can I expect to work on during a software defined radio internship?

As a Software Defined Radio (SDR) intern, you'll typically be involved in hands-on projects that focus on developing, testing, and optimizing radio communication systems using platforms like GNU Radio and SDR hardware such as USRP devices. Common responsibilities include writing and debugging signal processing algorithms, implementing modulation schemes, and analyzing RF signals. You may also collaborate with engineers and researchers to prototype new wireless applications, contribute to open-source SDR projects, and participate in team meetings to discuss technical challenges and project progress. This environment fosters practical learning and direct exposure to both hardware and software aspects of modern radio systems.

What are the key skills and qualifications needed to thrive as a software defined radio intern, and why are they important?

To thrive as a Software Defined Radio Intern, you need a solid understanding of digital signal processing, RF concepts, and programming (often in Python or C++), typically supported by coursework or a degree in electrical engineering or a related field. Familiarity with SDR platforms like GNU Radio, MATLAB, and hardware such as USRP devices is commonly required. Strong problem-solving skills, attention to detail, and the ability to communicate technical concepts clearly set candidates apart. These skills are crucial for developing, testing, and optimizing complex radio systems in dynamic research or engineering environments.

What is the difference between Software Defined Radio Internship vs RF Engineer?

AspectSoftware Defined Radio InternshipRF Engineer
Required CredentialsTypically pursuing or recent graduate in Electrical Engineering or related fieldBachelor's or Master's in Electrical Engineering, RF or Communications Engineering
Work EnvironmentResearch labs, development teams, testing environmentsDesign, testing, and deployment of RF systems in labs or field
Industry UsageWireless communication, defense, research projectsTelecommunications, aerospace, defense industries

The Software Defined Radio Internship focuses on hands-on experience with SDR technology, often for students or recent grads, while RF Engineers are full-time professionals designing and implementing RF systems. Both roles share similar educational backgrounds and industry applications, but differ in scope and career level.

Principal Radio Frequency Engineer

Two Six Technologies

Herndon, VA • On-site

Per diem

Posted 13 days ago

Job description

Overview of Opportunity 

Two Six Technologies is actively seeking a Principal Radio Frequency Engineer to join our Embedded Security Research team. The team is composed of intellectual individuals, passionate about software-defined radio (SDR), digital signal processing (DSP), and RF reverse engineering. The team is growing and looking for someone with an advanced RF engineering and signal processing background who has an understanding of how to serve as an RF Subject Matter Expert (SME) to lead technical planning, reverse engineer complex RF protocols, and architect solutions for embedded security research programs. If you are actively using SDR platforms, custom waveform synthesis, and advanced DSP techniques in Linux environments, the team wants to talk to you!

What you will do

  • Lead the technical planning, architectural design, and software execution for advanced DSP/SDR systems supporting critical embedded security research programs.
  • Provide subject matter expertise and technical mentorship to cross-functional engineering staff while solving complex challenges in communications, signal collection, and electronic warfare.
  • Reverse engineer complex COTS devices and RF protocols, isolate PRN codes, and synthesize custom RF waveforms to generate simulated signals.
  • Guide lab build-outs, define software toolchains, select SDR platforms, and validate generated signals using laboratory RF test equipment.
  • Contribute to project scheduling, budget preparation, and business development efforts by leading technical sections for proposals and white papers.

What you will need (basic qualifications)

  • Active DoD Top Secret clearance with SCI eligibility.
  • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, Physics, Mathematics (or equivalent military/IC experience) paired with 9+ years of experience in DSP, SDR development, and RF reverse engineering.
  • Proven capability to serve as a technical lead, including experience mentoring engineering staff, guiding project deliverables, and contributing to technical sections of proposal efforts.
  • Demonstrated experience reverse engineering complex RF protocols and COTS devices, deriving transmission parameters, generating custom waveforms, and decoding Pseudo-Random Noise (PRN) codes.
  • Extensive hands-on experience implementing custom SDR solutions on COTS platforms in Linux environments, executing baseline modulation schemes (FSK, PSK, QAM), and performing RF test equipment validation.

Nice to have (preferred)

  • Familiarity with space-based system signal structures (e.g., GPS L1/L2, GNSS, SATCOM), space-dominant modulations (QBPSK, BOC), and satellite simulation software (e.g., AGI STK) for Doppler shift mitigation.
  • Practical experience using reverse engineering tools such as Ghidra for firmware reverse engineering.
  • Deep understanding of digital communication concepts, including Forward Error Correction (FEC), Viterbi and Reed-Solomon decoding, interleaving, and framing analysis.
  • Prior experience authoring technical white papers, presenting at technical panels, or supporting proposal capture efforts within SIGINT or Electronic Warfare domains.

Security Clearance:

  • Active DoD Top Secret clearance with SCI eligibility.
