About Oransi Oransi is a Virginia based advanced manufacturer headquartered in a 156,000 square foot facility in Radford, VA. We design and build high performance air purifiers sold under the Oransi brand, along with electric motors, blowers, and fans for data center and IT equipment cooling and unmanned systems. Through our subsidiaries, Aslan Motion Technologies serves defense and unmanned systems customers, and Aviemore Technologies builds seal-less magnetic coupling pumps for data center liquid cooling. Founded in 2009 and self funded from the start, we are a team of learners, hard workers, and go getters who build real products for real customers. Our leadership team has spent more than 25 years building manufacturing companies together, and we are looking for people who want to grow with us. Our unmanned systems line includes NDAA compliant BLDC motors, ESCs, flight controllers, GPS modules, and seal-less pumps for air, sea, and land platforms, all manufactured in the United States. Customers include defense primes, government integrators, and drone manufacturers who need reliable, domestically built hardware. We are looking for a hands on RF Engineer to own RF design for our unmanned systems products, in a small team where your work goes straight from the bench to the build floor. The Role We are looking for an RF Engineer to lead the design, integration, and validation of RF subsystems for our unmanned systems product line. You will work on GNSS receivers, antennas, and datalink interfaces, and you will make sure our flight controllers and power electronics perform in electrically noisy, contested environments. This is a hands-on role spanning schematic and layout through bench testing, field testing, and production support. What You Will Do Design and optimize RF circuitry for GNSS modules, including front ends, LNAs, filtering, and antenna matching networks Select, integrate, and characterize antennas for small UAS and other unmanned platforms, balancing performance against size, weight, and power constraints Support integration of command and control datalinks and telemetry radios into customer platforms Improve GNSS resilience against jamming and spoofing through hardware design, antenna selection, and system architecture Identify and resolve EMI and EMC issues between RF subsystems, motor drives, ESCs, and flight control electronics Review PCB layouts for RF performance, grounding, shielding, and signal integrity Build and run test procedures using spectrum analyzers, VNAs, signal generators, and GNSS simulators Plan and support field and flight testing, then turn the data into design improvements Prepare for and support EMC compliance testing and customer qualification programs Work with customers to develop custom variants tailored to their platforms Help establish RF test processes for production and quality control at our Radford facility What You Bring Bachelor's degree in Electrical Engineering or a related field 3+ years of RF design experience, ideally on unmanned systems, avionics, or defense electronics Solid grounding in RF fundamentals: impedance matching, link budgets, noise figure, filtering, and transmission lines Hands-on experience with RF lab equipment including spectrum analyzers, VNAs, and signal generators Experience with RF simulation tools such as Keysight ADS, Ansys HFSS, or CST Experience reviewing or designing RF PCB layouts in Altium, KiCad, or similar Working knowledge of GNSS systems (GPS, Galileo, GLONASS, BeiDou) and multi-band receivers Comfort working across disciplines with firmware, mechanical, and power electronics engineers Ability to work on site in Radford, VA U.S. citizenship required due to the nature of our work and applicable export control regulations Nice to Have Experience with anti-jam GNSS techniques such as CRPA antennas or null steering Familiarity with MIL-STD-461 and

MIL-STD-810

Experience with software defined radios and tactical datalinks Experience with drone flight stacks such as PX4 or ArduPilot Active or previous security clearance Experience taking hardware from prototype into production FAA Part 107 certification Why Oransi Build hardware that directly supports U.S. and allied warfighters Join an established, self-funded manufacturer with a leadership team that has built and exited companies before High ownership and visibility in a focused engineering team In-house manufacturing, so you can see your designs go from bench to production line under one roof Located in Radford, with easy access to the Blue Ridge Mountains and the Virginia Tech research community Health, dental, and vision insurance 401(k) / retirement plan Paid time off and holidays Oransi LLC is an equal opportunity employer.
