About this role
GreenWave Radios is seeking an embedded firmware engineer for a six-month contract role focused on unit testing and low-level software development for their Hermes64 RF SoC, a power-efficient chip designed for Open RAN 5G networks. Working remotely from Bangalore, you would design and develop bare metal and RTOS-based firmware, particularly device drivers and lower PHY layer code, while running tests both in simulation and on actual hardware. The position involves close collaboration across applications, systems, hardware, and software teams, with individual contribution as the primary focus alongside some technical leadership and mentorship opportunities.
This role demands at least six years of embedded systems experience, with a strong foundation in ARM SoC development, RTOS principles, and C/C++ proficiency. You'll need hands-on expertise in unit testing frameworks like Unity or GoogleTest, low-level driver development, register-level programming, and debugging tools such as GDB and JTAG. Familiarity with modern development workflows (Git, Jira, Agile) and solid communication skills are essential. Prior SoC product development experience and knowledge of cellular wireless protocols (4G LTE or 5G NR) would strengthen your candidacy, as would proficiency in Claude AI for code generation and technical documentation.
