Jobs at Greenwave Radios

Lead design verification for 5G Open RAN SoC products, covering ARM Cortex subsystems, packet-processing blocks, and high-speed interfaces. Develop SystemVerilog/UVM testbenches, Python/C++ reference-model integrations, constrained-random tests, assertions, coverage, regressions, and hardware/software co-verification environments. Collaborate with architects, RTL, firmware, and systems teams while supporting emulation and FPGA prototyping. Drive verification planning, debugging, coverage closure, and transition of verification scenarios into firmware validation flows.

Senior design verification engineer responsible for verifying wireless DSP hardware blocks and 5G SoC designs. Develops UVM and SystemVerilog testbenches, integrates MATLAB and Python reference models, performs HW/SW co-verification, and executes directed and constrained-random testing. Responsibilities include coverage closure, assertions, regression analysis, debugging, verification planning, emulation, FPGA prototyping, and automated verification flows using scripting languages.

Six-month contract role developing and testing bare-metal and RTOS firmware for 5G SoCs, including device drivers and lower PHY software. Responsibilities include simulation and hardware testing, debugging, architecture and code reviews, documentation, requirements collaboration, and technical mentorship. Requires embedded C/C++, ARM SoC experience, RTOS expertise, unit testing, mocking, build systems, register-level programming, interrupts, DMA, concurrency, and boot/runtime initialization testing.

The Tech Lead Wireless Firmware is responsible for designing, developing, and verifying bare metal and RTOS-based firmware for a 5G SoC, collaborating with teams, and providing technical leadership.

Lead end-to-end PCB architecture, schematic capture, and layout for high-performance cellular base stations. Design RF, analog, digital, high-speed SerDes, and power circuits; optimize stack-up, signal/power/thermal integrity, drive DFM/vendor reviews, support board bring-up, and mentor other designers while collaborating cross-functionally.

Develop and automate system-level RF validation for next-generation RF SoC platforms from silicon bring-up through production. Design 3GPP conformance tests, build Python and MATLAB automation frameworks, characterize RF subsystems, analyze performance metrics and large datasets, debug hardware and software issues, optimize test instrumentation, and create regression environments, technical reports, and validation documentation.

Lead a small team to design and deliver FPGA/ASIC Front Haul Gateway solutions from architecture through production. Own microarchitecture, CPU/bus/memory subsystems, IP integration, front-to-back FPGA flows, verification, and hardware validation while coordinating cross-functional teams and maintaining design quality standards.

Lead and mentor a QA team in designing and maintaining automation test scripts for 5G products, aligning efforts with project requirements.

Design and deliver ultra-high-efficiency RF power amplifiers for 5G FR1 base stations. Lead device evaluation, modeling, circuit design, EM-aware PCB layout, lab bring-up, and production support. Collaborate with systems, RF/analog, digital, and firmware teams, document designs, and present results to stakeholders.
