W2\nWork Requirements: US Citizen, GC Holders or Authorized to Work in the U.S.\nABOUT THIS FEATURED OPPORTUNITY\nJoin an engineering team developing a satellite broadband system that connects satellites in orbit with ground terminals. This team works at the intersection of RF, digital signal processing, embedded firmware, and hardware testing to characterize and improve real-world wireless links.\nThis is a hands-on, lab-based opportunity where you'll work directly with early-stage silicon and hardware, bringing up new devices, debugging issues, developing firmware, and building automation that replaces manual bench testing. You'll play a key role in making PHY testing more repeatable, scalable, and data-driven.\nTHE OPPORTUNITY FOR YOU\nPerform post-silicon bring-up and debug of early-stage hardware and embedded systems.\nDevelop and modify low-level embedded firmware, primarily using bare-metal C , to support hardware testing and characterization.\nBuild hardware-in-the-loop (HITL) test automation using Python to drive real hardware and laboratory test equipment.\nConfigure and troubleshoot lab setups using Vector Signal Analyzers (VSAs), Vector Signal Generators (VSGs), and Rohde & Schwarz equipment .\nCharacterize wireless link performance across different operating conditions, accounting for path loss, cabling, attenuation, and other bench variables.\nDevelop automated BLER, SNR/EsNo, MCS, and parameter sweeps to evaluate PHY performance and enable repeatable regression testing.\nCreate automated test reports with clear pass/fail results, summary statistics, and test data .\nDebug hardware, firmware, and test-setup issues in the lab and identify root causes.\nDocument test frameworks and procedures so the broader engineering team can add and execute new test scenarios.\nApply knowledge of embedded concepts such as interrupts, timing, and hardware/firmware interactions .\nKEY SUCCESS FACTORS\n RF / Wireless Communications Expertise: Strong understanding of wireless communication fundamentalsincluding BLER, SNR/EsNo, modulation and coding schemes (MCS), link budgets, and path loss.\n\nEmbedded Firmware Development: Hands-on experience developing and debugging bare-metal C firmware on embedded hardwareincluding understanding of interrupts, timing, and hardware/firmware interactions.\n\nEarly-stage firmware development: Experience bringing up and debugging new or early-stage silicon, boards, or hardware in a laboratory environment.\n Hardware-in-the-loop (HITL) test automation: Has personally built automated test frameworks that drive real hardware.\nNICE TO HAVES\nExperience with satellite, aerospace, or broadband communications.\nExperience working in fast-moving, hardware-in-the-loop engineering environments.\nExperience with AI-assisted software development tools.\nFamiliarity with DSP, modulation/coding, or PHY-layer performance characterization.\nHands-on experience with Rohde & Schwarz equipment, VSAs, VSGs, or similar RF test instrumentation.\nExperience developing automated regression testing and pass/fail reporting for hardware or PHY systems.\nAbout INSPYR Solutions\nTechnology is our focus and quality is our commitment.
