You will work at the intersection of radar hardware, digital signal processing, embedded systems, and interceptor guidance. This role is central to Wardstone’s mission: your system determines whether our interceptor knows exactly where to strike. You will work directly with founders, build RF test rigs, run high-speed experiments, and ship seeker systems into hardware that performs real intercepts.\nWhat You’ll Do\n RF & Radar System Integration: Own radar sensor selection, antenna integration, Tx/Rx chain analysis, and high-speed data interfaces (e.g., PCIe, high-speed ADCs/DACs) within the avionics architecture.\nReal-Time Signal Processing: Build low-latency processing pipelines capable of tracking high-speed objects, including Doppler processing, CFAR algorithms, range-Doppler mapping, and clutter/ECM rejection.\nSensor Fusion & Estimation: Fuse radar track data with IMU, GPS, and onboard state estimators using EKF/UKF filters to build highly accurate perception-to-guidance interfaces for closed-loop control.\nVerification & Validation: Design RF test rigs and conduct hardware-in-the-loop tests using anechoic chambers, radar scene generators, RCS reference targets, and flight dynamics models.\nRequired Qualifications\nEducation & Core Knowledge: B.S. in EE, Physics, Aerospace, or similar, with deep proficiency in radar physics, electromagnetics, and noise modeling.\n Algorithms & Software: Strong background in digital signal processing (DSP), filtering, and programming (C++/Python), with experience implementing real-time radar detection and tracking.\n Hardware & Testing: Hands-on experience testing radar architectures (FMCW, Pulsed Doppler, AESA) using RF lab equipment like Spectrum Analyzers, VNAs, and Oscilloscopes.\nWorking with Suppliers: Experience sourcing components and performing make vs buy analysis. \nUS Person or Lawful Permanent Resident status required.\nNice to Haves\n Domain Expertise: Background in missile seekers, high-speed air-to-air systems, counter-ballistic radar tracking, or electronic warfare (EW) resilience.\n Compute Acceleration: Experience with FPGA-based signal processing (VHDL/Verilog) or GPU acceleration for heavy radar pipelines.\nElectromagnetics: Familiarity with antenna array design, beamforming, radome EM integration, or atmospheric RF attenuation.\n Simulation: Knowledge of radar cross-section (RCS) modeling, synthetic target generation, and MIL-STD high-G testing environments.\nCompensation\nThe base pay range for this role is $100,000 - $160,000 per year.","description_format":"text","description_chars":2703,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military","Missiles","Defense Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-25T17:22:42Z"}],"liveness":{"score":35,"band":"fade","label":"Fading","p_open":0.9,"p_active":0.512,"p_room":0.75,"age_days":35,"expected_fill_days":40,"reasons":["conf:52","win:late"],"computed_at":"2026-09-28T05:45:00Z"},"pay":{"stated_usd_annual":160000,"is_top_pay":false},"html_url":"https://alion.io/job/wardstone-rf-sensing-engineer","json_url":"https://alion.io/job/wardstone-rf-sensing-engineer.json","meta":{"generated_at":"2026-09-29T04:11:40Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":3943,"day_limit":5000,"remaining_today":1057,"minute_limit":60,"resets_at":"2026-09-30T00:00:00Z"}}}
