About The Position

We are seeking a highly skilled and motivated RF Engineer with Software Defined Radio (SDR) expertise to join our team. You will be responsible for utilizing SDR technology to design Counter Unmanned Aircraft Systems products for two primary functions. First, products that receive UAS command and control signals for identification. Secondly, products that emit jamming signals to counter the UAS. This role requires a strong background in engineering, RF communication protocols, and SDR technologies. You will work with our cross-discipline team to help develop new, advanced counter UAS products.

Requirements

• Excellent written and oral communication skills. The ability to write clear, well documented test plans and procedures for RF devices and systems
• Adaptable, eager to learn, and create, with a proactive attitude towards continuous improvement
• Ability to work in a small team to rapidly prototype and develop new products
• 7+ years relevant experience working with RF Devices and Software Defined Radio
• Responsible for RF aspects of the initial design and sustainment of products to support the new product introduction (NPI) process and specifically the lead on SDR selection, configuration and testing for RF emitter and RF receive products
• Develop designs that meet product requirements and implement those designs using modern electrical schematic capture tools and should have experience in Altium
• Collaborate in the requirements analysis and the RF design for projects by working closely with mechanical and software groups; and provide high quality estimates of project scope
• Incorporate continuous improvement of engineering development and manufacturing processes
• Develop test strategies and plans for both design validation and production test in accordance with industry standards and customer requirements
• Demonstrated experience working with SDRs and RF communication systems and incorporating SDRs in product designs.
• Hands-on experience in collecting and analyzing RF signals using SDR hardware and software tools
• Familiarity with various modulation and demodulation techniques, including but not limited to FSK, PSK, QAM, and OFDM
• Experience with protocol analysis and reverse engineering techniques to decipher communication protocols from raw RF data
• Knowledge of field-programmable gate array (FPGA) development and VHDL coding as it relates to SDR architecture
• Proficiency in using professional SDR platforms such as the Ettus USRP family, Analog Devices AD936x family, or similar tools for waveform generation.
• Ability to implement signal processing algorithms, demodulation techniques, and protocol decoding strategies using SDR frameworks such as Software Communications Architecture (SCA), GNU Radio, REDHAWK and/or X-Midas
• Skilled in programming languages commonly used in SDR programming, such as Python, C/C++, or MATLAB
• Experience in a laboratory environment working with SDRs and associated test equipment
• Strong understanding of RF signal processing, signal analysis, and wireless communication principles
• It is an essential requirement for the person in this role to have a legal right to work in the United States and be eligible to obtain any required Export Authorization and DoD Clearance.
