About The Position

Two Six Technologies is seeking a Digital Signal Processing (DSP) Engineer to work in Herndon, Virginia, advancing digital signal processing and wireless systems through hands-on research and development in a laboratory environment. The engineer will help develop solutions supporting the intelligence community and work on a multidisciplinary team of RF engineers, embedded developers, and security researchers. The work includes reverse engineering real-world systems, designing and implementing wireless algorithms, and developing mission-focused RF applications. The role focuses on designing, implementing, and optimizing DSP algorithms for wireless systems; analyzing captured waveforms; evaluating RF receiver, transmitter, and modem architectures; and prototyping with software-defined radio (SDR) hardware and RF test equipment. The engineer will also contribute technical expertise and reusable software design patterns, tools, infrastructure, and SDR building blocks to a centralized development repository. An active Top Secret clearance is required, with the ability to obtain and maintain a TS/SCI. The posted annual salary range is $118,024–$177,035. Two Six Technologies lists medical, dental, and vision insurance, life and disability insurance, retirement benefits, paid leave, tuition assistance, and professional development among its offerings.

Requirements

Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related scientific discipline.
Software-defined radio expertise, including receiver architectures, channelization, modulation and demodulation techniques, error-correcting codes, and spectral analysis.
Experience designing and implementing receiver, transmitter, and modem signal chains in cellular, radio, or RF communication systems.
Experience with physical layer (PHY) and Medium Access Control (MAC) layer concepts, including waveform processing, synchronization, channel estimation, framing, and link-level behavior.
Familiarity with open-source signal processing libraries and frameworks.
Experience with common SDRs, such as Ettus USRP Series, BladeRF, and PlutoSDR.
At least 3 years of experience with one or more modern development languages: C, C++, Embedded C, or Python.
Experience with collaborative Git workflows, including branching strategies, pull requests, and conducting code reviews.
Active Top Secret clearance and the ability to obtain and maintain a TS/SCI.

Nice To Haves

Demonstrated ability to architect and implement end-to-end wireless communication systems with real-world performance requirements.
Advanced degree in Electrical Engineering or a related technical discipline.
Proficiency with SDR tools such as GNU Radio, Radio Hacker, GQRX, Vivado, or ModelSim.
Hands-on experience working with one or more common DSP providers such as Texas Instruments (TI), Analog Devices (AD), or STMicroelectronics.
Active TS/SCI clearance.

Responsibilities

Design, implement, and optimize digital signal processing algorithms for real-world wireless systems.
Perform signal detection, identification, classification, and decoding of captured waveforms.
Develop and evaluate receiver, transmitter, and modem architectures for RF systems.
Perform RF signal reception and transmission using common modulation schemes, including FSK, PSK, QAM, and OFDM.
Develop prototypes in laboratory environments using SDR hardware and RF test and measurement equipment.
Contribute subject matter expertise in DSP, Software Defined Radio (SDR), and wireless communications systems.
Contribute software design patterns, tools, and infrastructure to a centralized repository to build maintainable, reusable SDR building blocks.
