## Description

We're seeking a skilled RF Hardware Engineer to join our growing team. As an RF Hardware Engineer, you will design, test, and build RF Systems (Tx / Rx) for RF signals (ex. communications, RADAR, navigation) UHF through X-Band.

This role requires an onsite presence in our El Segundo, CA HQ; a remote work environment is not considered for this opportunity.

Key Responsibilities:

* Design, validate & deliver RF payload subsystems: Design, Integration and Testing of Antennas, RF front ends, SDRs and provide validation of operation. Support development and analysis of RF performance metrics.

* Own requirements, ICDs, and verification from concept through delivery

* Stay current: Track and insert advances in relevant technologies, SDRs, RF Systems, RF machine learning, and PNT.

Qualifications:

* BS/MS in Electrical Engineering, Computer Engineering, or related field

* Antenna and receiver design across analog/RF/mixed-signal domains: mixers, PLLs/LOs, gain/linearity/noise trades; ability to turn simulations into reality.

* Channelizers & wideband architectures: filter banks, analog/digital down conversion, sample-rate planning, clocking/synchronization.

* Willingness to support critical test events that occasionally require extended hours/weekends

* Ability to obtain and maintain a security clearance

* Must be a U.S. Person (see ITAR Regulations below) due to required access to U.S. export-controlled information or facilities

Bonus Points:

* PhD in Electrical Engineering, Computer Engineering, or related field

* 5+ years’ experience with EW subsystems and payloads

* EA/ECM technique design (deception, Digital RF Memory, coherent/non-coherent techniques)

* Digital Signal processing: Design characterize and deliver channelizers, wideband detection/classification, MIMO/digital-arrays, and algorithms in MATLAB/Python/C++

* Communication / Waveform system design

* RF machine learning for emitter ID, modulation/classification, anomaly detection, PDW creation

* Tools Experience: ADS/AWR/SystemVue, MATLAB/Simulink, Python (NumPy/SciPy), GNU Radio/SDR (USRP/RFSoC), VITA-49; HDL/firmware experience; also helpful (Vivado/Quartus/Libero).

* Clearance: Active Secret or ability to obtain and maintain; TS/SCI eligibility preferred. ITAR/EAR-controlled work. Learn more about Security Clearances here.

* Field work: supporting periodic travel for flight tests and customer demonstrations/support

* Mindset: Builder-tester who loves first-principles RF, rapid lab iteration, and getting hardware flying fast

What We Offer:

* Competitive salary, stock options and benefits, including health, vision and dental.

* 401K enrollment at 90 days.

* Generous PTO + most Federal Holidays observed.

* Collaborative and inclusive work environment.

* Access to the latest tools and technologies.

* High levels of responsibility and autonomy.

* Professional growth and development opportunities.

* Access to the hardest problems in electronic warfare.
