Radio Frequency (RF) Systems - Electrical Engineer

RF EngineerWe're looking for an RF Engineer to design, optimize, and deploy advanced radio systems that support our autonomy and airspace intelligence platform. This role sits at the intersection of hardware, signal processing, and real-world deployment. You'll own antenna design and RF performance across our systems, while also contributing to next-generation capabilities in passive RF-based drone detection and tracking. This is not a pure research role — you'll be expected to build, test, iterate, and ship hardware that performs in the field.What You'll Be DoingDesign, prototype, and optimize RF systems for airborne and ground-based platformsDevelop, tune, and validate antenna systems (custom and off-the-shelf) for performance, range, and reliabilityConduct RF testing, measurement, and analysis (VNA, spectrum analyzer, SDRs, etc.)Improve signal integrity, reduce noise/interference, and optimize system-level RF performanceDesign and iterate on in-house antenna solutions (patch, dipole, phased arrays, etc.)Build and test RF pipelines for passive detection and classification of wireless emittersDevelop and implement techniques for RF-based localization and triangulationWork with SDR platforms to capture, process, and analyze RF signals in real timeCollaborate with software and autonomy teams to integrate RF data into higher-level systemsSupport field testing and deployment, including debugging real-world RF issuesContribute to hardware architecture decisions across communications and sensing systemsTechnical Requirements RequiredStrong fundamentals in RF engineering, electromagnetics, and antenna theoryHands-on experience with RF test equipment (spectrum analyzers, VNAs, signal generators)Experience designing, tuning, or modifying antennasSolid understanding of signal propagation, interference, and link budgetsExperience working with SDRs (e.g., USRP, HackRF, BladeRF, etc.)Familiarity with RF signal processing concepts (filtering, modulation, detection)Experience debugging real-world RF systemsAbility to prototype and iterate quickly in a lab environmentPreferredExperience with RF-based localization / triangulation techniques (TDOA, RSSI, AoA, etc.)Background in passive RF sensing or spectrum monitoringExperience with drone communication protocols and RF signaturesFamiliarity with embedded systems or firmware (C/C++ or similar)Experience designing RF systems for harsh or dynamic environments (e.g., airborne systems)Knowledge of regulatory constraints (FCC, spectrum compliance)Exposure to phased arrays or beamforming systemsOur StackHardware / RF: Custom antennas, SDR platforms, RF test equipmentProcessing: Real-time signal processing pipelinesSystems: Integrated with autonomy, telemetry, and distributed infrastructureWhat We're Looking ForWe need someone who identifies problems, owns them end-to-end, and drives solutions into production. You'll excel in this role if you:Think in terms of systems, not componentsCan take a vague problem and turn it into a working solutionAre comfortable moving between theory, lab work, and field deploymentBias toward building and testing over excessive modelingThrive in fast iteration cycles with real-world constraintsWant to push the boundaries of RF-based sensing and detectionBenefitsHealth, Dental, and Vision Insurance: 100% of premiums covered for employees, 80% for dependentsCompensation: Competitive salary with performance-based bonusesEquity: Stock options offering real ownership in what you're buildingRetirement: 401(k) planInsurance: Life, short-term, and long-term disability coveragePerks: Free daily lunch and dinner, with snacks and drinks stocked in the office
