Staff RF Engineer, Coexistence & Desense

Job DescriptionOur Mission:At General Motors, our product teams are redefining mobility. Through a human-centered design process, we create vehicles and experiences that are designed not just to be seen, but to be felt. We’re turning today’s impossible into tomorrow’s standard —from breakthrough hardware and battery systems to intuitive design, intelligent software, and next-generation safety and entertainment features.Every day, our products move millions of people as we aim to make driving safer, smarter, and more connected, shaping the future of transportation on a global scale. Job OverviewGeneral Motors is transforming into a software‑defined, technology‑driven automotive company, with a growing emphasis on in‑house hardware and RF system design to enable faster innovation, deeper system integration, and improved product quality.We are seeking a highly skilled Senior RF Coexistence Engineer to support multi‑radio performance execution across GM’s next‑generation product platforms. In this role, you will focus on coexistence behavior, throughput, latency, and system‑level performance across cellular, Wi‑Fi, Bluetooth, GNSS, UWB, and emerging wireless technologies.This is a senior individual contributor role that plays a critical part in GM’s in‑house design (IHD) strategy, embedding coexistence expertise early in design, validation, and integration cycles while working within agile, cross‑functional development teams.Key ResponsibilitiesCoexistence Execution & OwnershipOwn coexistence and desense performance for assigned systemsDevelop and implement multi‑radio coexistence solutions within defined vehicle and system architecturesSupport early design phases by identifying coexistence risks and opportunities aligned with GM’s in‑house development roadmapPartner with internal design teams to reduce dependency on late‑stage supplier fixesAnalyze and improve:Throughput degradationLatency, packet loss, and jitterRadio contention and scheduling inefficienciesEvaluate coexistence behavior in real‑world, in‑vehicle scenarios:Simultaneous radio operation (e.g., Wi‑Fi + Bluetooth audio + cellular data)Support system trade‑offs balancing performance, power, cost, and useCollaborate closely with internal:RF, antenna, PCB, SoC, and firmware teamsEnable faster iteration cycles by connecting:Early simulationBench and lab validationVehicle‑level testingSupport agile development models through incremental learning, fast debug, and early risk retirementCross‑Functional Technical IntegrationInfluence system design decisions to improve coexistence performance, including:Antenna placement and isolationRF front‑end architectureClocking and aggressor managementCollaborate with firmware and software teams on:Coexistence algorithmsScheduling and arbitration mechanismsFrequency hopping and time‑domain coordinationAct as a technical bridge between hardware realities and protocol‑level behaviorCoexistence Testing & ValidationDevelop and execute coexistenc...
