We are looking for an Embedded Software Development Engineer to join the RBKS ASIC team, building firmware and diagnostics software that enables silicon bring-up, production testing, and product integration for Ring's custom SoCs. ASIC bring-up is a hardware + software co-debug exercise. This role ensures we have dedicated firmware engineering capability on-site to resolve silicon issues without round-trip delays, directly reducing bring-up Key job responsibilities Develop and maintain silicon bring-up diagnostics and production test software • Write low-level drivers and BSP code for custom ASIC peripherals (boot ROM, memory controllers, communication interfaces) • Support on-site bring-up at contract manufacturers (Vietnam, China) and Ring Taipei • Assist product teams with firmware integration, boot sequence validation, and peripheral bring-up • Debug software-related silicon issues during EVT/DVT/PVT phases through register-level analysis • Develop automated test scripts and diagnostic tools for ATE and bench validation • Collaborate with the hardware team to define and execute hardware-software co-validation plans • Contribute to production test flow development ensuring manufacturing quality and yield A day in the life You'll work hands-on with early silicon—writing the first code that runs on a new chip, debugging boot failures, and building the diagnostic suite that validates every peripheral. About the team We're a small, nimble ASIC team building Ring's custom silicon from the ground up. We work in a vertically integrated environment where you see your work directly impact the products millions of customers rely on daily.
