Physical stores still have not. RADAR is changing that.\nRADAR is building the data infrastructure layer for the physical world, starting with retail. Our hardware-enabled SaaS platform uses proprietary overhead sensors, software, and AI-powered analytics to locate every product in a store, continuously, down to the fixture. We are deployed across 1,500+ stores with retailers including American Eagle Outfitters and Old Navy, processing tens of billions of real-world events every day, delivering 99%+ accuracy in complex, noisy environments - at fleet scale.\nRADAR is one of the best-funded companies in retail technology, backed by a recent Series B financing at a $1 billion valuation. Inventory accuracy is only the beginning. We believe RADAR can become foundational infrastructure for the physical economy, powering new AI-driven commerce experiences across retail and beyond.\nJoin us if you want to work on a large, unsolved, technically challenging problem with an ambitious team building category-defining technology.\nOUR VALUES\nMission-Driven: We're transforming retail with cutting-edge technology and building something that truly matters.\nCollaborative Team: We thrive on curiosity, shared goals, and solving complex problems together.\nHigh Impact: You’ll make meaningful contributions from day one and help shape the future of our product and company.\nClear Communication: We value honesty, humility, and respectful dialogue-everyone’s voice matters.\nBalanced Lives: We work hard, but not at the expense of well-being. We respect time, boundaries, and life outside of work.\nDiverse Perspectives: We believe better ideas come from diverse backgrounds, experiences, and viewpoints.\nEmpathy-Driven Design: We build with deep respect for our end users, listening closely to their feedback and needs.\nABOUT THE JOB\nIn this role, you will lead and execute the design, development, and evaluation of next-generation RFID sensor antennas. You will be responsible for the full development lifecycle-from initial simulation-first modeling and multi-element array synthesis to hands-on validation in anechoic environments and site-specific propagation analysis. You will also work closely with cross-functional teams spanning hardware, RF systems, and product engineering to deliver robust, scalable RFID sensor-antenna solutions.\nResponsibilities:\nDesign, simulate, and optimize custom RFID sensor antennas, including single-element and multi-element array configurations using electromagnetic simulation software.\nPerform full-wave electromagnetic simulations to evaluate antenna performance metrics including impedance matching, radiation patterns, efficiency, isolation, polarization, and coupling of antenna designs.\nConduct precise antenna calibration and performance characterization in an anechoic chamber.\nOversee the fabrication of PCB-based antennas and seamless integration with RF front-end components.\nWork alongside hardware and software teams to integrate antenna solutions into compact sensor form factors.\nABOUT YOU\nRequired:\nYou have a BS degree or higher in Electrical Engineering, Applied Physics, or a related field.\nYou have 10+ years of relevant industry experience in antenna design and RF systems.\nYou have a strong background in electromagnetics and antenna theory.\nYou have proven expertise with full-wave electromagnetic simulation tools (e.g., FEKO, HFSS, CST, or similar).\nYou have direct experience designing and evaluating multi-element antenna arrays.\nYou have experience evaluating, selecting, and integrating commercial antenna products, including managing vendor specifications and hardware validation.\nYou have hands-on experience with Vector Network Analyzers and antenna calibration procedures in anechoic chambers.\nYou have a strong focus on verification and validation, with expertise in applying rigorous test methodologies to both simulated and measured RF data.\nYou have experience correlating system-level performance with physical antenna characteristics.\nYou have experience leveraging cloud computing platforms to scale simulation workloads and manage large RF datasets.\nYou have a proven track record of successfully delivering commercial wireless products from initial design through to high-volume deployment.\nYou have strong verbal and written communication skills.\nPreferred:\nYou have familiarity with sensor-integrated or constrained-form-factor antennas.\nYou have familiarity with FCC/ETSI standards for wireless devices.\nYou have knowledge of scripting or automation (e.g., Python, MATLAB) for simulation workflows and data post-processing.\nWHAT YOU'LL DO\nIn your first 30 days, you will:\nLearn Radar’s mission, technology stack and core values.\nComplete onboarding and security compliance training.\nBecome familiar with existing RFID systems, antenna designs, and simulation workflows.\nReview current measurement setups, calibration procedures, and test methodologies.\nSet up and validate electromagnetic simulation toolchains to ensure alignment with existing models.\nIn your first 60 days, you will:\nPerform baseline antenna measurements and calibration in an anechoic chamber to verify hardware performance.\nCompare simulation results with chamber measurement data to refine model accuracy.\nIn your first 90 days, you will:\nLaunch the design phase for next-generation RFID sensor antenna based on the initial findings and system requirements.\nAt RADAR, your base pay is one part of your total compensation package. The expected base salary range for this position is $190,000 - $233,000. Individual pay is determined by work location and additional factors, including job-related skills, experience and relevant education or training.You will also be eligible to receive other benefits including: equity, comprehensive medical and dental coverage, life and disability benefits, 401k plan, flexible time off, and paid parental leave. The pay range listed for this position is a good faith and reasonable estimate of the range of possible base compensation at the time of posting. \nResearch has shown that women & underrepresented minorities are more likely to read lists of requirements and consider themselves unqualified if they don't meet every single one.
