Are you ready for your next challenge?

We're looking for a highly skilled RF Signal Processing & Communications Engineer to join our team in Huntsville, AL . In this role, you'll support the development, testing, and evaluation of advanced datalink and communications systems for tactical and airborne platforms.

What's in it for you?

You'll apply your expertise in RF systems, digital signal processing, and communications theory to conduct performance testing in lab, field, and flight environments. Your work will directly support Department of Defense (DoD) customers by providing in-depth performance and vulnerability assessments of advanced datalink waveforms.

As a technical subject matter expert (SME), you'll also collaborate closely with government stakeholders to inform product development, shape acquisition strategies, and guide technology transitions.

THE CHALLENGE (primary responsibilities)

Provide subject matter expertise in RF signal processing and communications with a focus on tactical datalink systems (e.g., CDL, SATCOM, LOS / BLOS).

Plan, execute, and support datalink testing activities in lab settings, as well as field and flight test operations.

Support the development of test plans, procedures, and technical reports.

Analyze and assess waveform performance, resilience, detectability, and vulnerabilities in operationally relevant scenarios.

Interface with government stakeholders, test teams, and integration partners to ensure test objectives and system requirements are met.

WHAT SETS YOU APART (basic qualifications)

Bachelor's degree in Electrical Engineering, Physics, or a related field and a minimum of 8 years of relevant experience OR Master's degree in Electrical Engineering, Physics, or a related field and a minimum of 6 years of relevant experience in RF signal processing, communications, or Electronic Warfare (EW)

Solid understanding of RF theory, including propagation, schematics, RF testing, and link budget analysis, with emphasis on over-the-air signal detection

Proficiency in core signal processing concepts, including Fourier transforms, filtering, noise modeling, and signal modeling

Strong understanding of digital modulation techniques, coding, synchronization, and waveform design

Strong analytical skills with proficiency in MATLAB (object-oriented preferred) or similar tools

Hands-on experience with RF lab equipment such as spectrum analyzers and signal generators

Strong written and verbal communication skills, with the ability to develop detailed technical reports and briefings

Experience with radio testing in lab and field environments, including flight tests

Active SECRET security clearance and the ability to maintain it (Top Secret eligibility preferred)

Preferred Qualifications

Master's or Ph.D. degree with an emphasis in electromagnetics

Experience with spread spectrum techniques and concepts

Familiarity with signal detection techniques, including energy and feature-based detection

Knowledge of advanced signal analysis techniques such as cyclic autocorrelation and cepstral analysis

Experience with EW testing

At Leidos, we don't want someone who "fits the mold"-we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, "what's next?" before the dust settles on "what's now."

If you're already scheming step 20 while everyone else is still debating step 2... good. You'll fit right in.
