You'll translate real-world RF and protocol requirements into silicon-level specs, working at the intersection of RF, baseband, and massive MIMO — all the way from architecture to lab validation. This is a hands-on, high-impact role at a company that ships. ### What You'll Do - Define and own system-level architecture for cellular SoCs, including link budgets, system partitioning, mMIMO beamforming chain design, and performance trade-off analysis - Architect and specify O-RAN compliant subsystems — define split options (7.2x, 6, 8), fronthaul interface requirements, and RU/DU functional partitioning in coordination with protocol and firmware teams - Develop and maintain detailed system specifications covering RF front-end, baseband, clocking, power, and RF/digital interfaces, serving as the authoritative reference for IC design teams - Build and run system simulations (RF link, mMIMO beamforming gain, interference, EVM, sensitivity, dynamic range) to validate architecture decisions before tape-out - Lead lab bring-up and characterization of prototype hardware, including hands-on use of spectrum analyzers, signal generators, VNAs, oscilloscopes, and protocol analyzers to validate RF and system performance - Define test plans and acceptance criteria for system-level performance, and work closely with test engineers to implement automated measurement flows in the lab - Partner with RF, analog, digital, and firmware teams to resolve cross-domain issues discovered in simulation or lab — own the path from root cause to silicon fix - Drive system-level compliance verification against 3GPP 5G NR and O-RAN Alliance specifications, and represent GreenWave in standards and alliance working group discussions where applicable - Produce clear architecture documents, design review materials, and technical trade-off memos that inform product and executive decisions - Assist in mentoring junior systems engineers; establish best practices for system modeling, specification, and lab methodology ### What You Bring - 8+ years of hands-on experience in wireless systems development (LTE, 5G NR) - PhD in Electrical Engineering required - Proficient in signal processing analysis/modeling skills with Matlab, Python or C/C++ - Strong understanding of communication theory & signal processing related algorithms design (such as timing recovery, signal estimation and detection, MIMO signal estimation and detection, automatic gain control, channel estimation, equalization, coding theory, beamforming, etc.) - Familiar in 5G NR system architecture — PHY layer, numerology, beamforming, and massive MIMO (mMIMO) antenna system design - Experience with O-RAN architecture: functional split options, O-RU/O-DU/O-CU definitions, fronthaul (eCPRI/CPRI) specifications, and O-RAN Alliance WG4/WG7 compliance - Proven lab experience — comfortable operating and interpreting data from spectrum analyzers, signal generators, VNAs, oscilloscopes, and RF test equipment in a prototype bring-up environment --- Data: alder (https://alderhq.app).
