Embedded Software Engineer

We engineer connectivity and embedded compute solutions that power connected devices worldwide. With decades of experience, our solutions are secure by design, globally compliant and supported over long life cycles.

The Embedded Software Engineer designs, develops, and supports Wi-Fi radio firmware and driver software for Ezurio's wireless connectivity products, working closely with the RF hardware development team in the USA and Taiwan, program management, and customers to deliver reliable, innovative, and resilient embedded software. The ideal candidate is comfortable working close to the metal - register-level access, bootloaders, and drivers in a resource-constrained environment - as well as building the connectivity stacks that sit above them, and brings strong debugging and root-cause analysis skills to complex hardware/software and RF interaction issues.

Deep 802.11 protocol expertise is not required; we are willing to train a strong embedded/RTOS candidate on the Wi-Fi-specific pieces. Experience developing software for network protocols (Wi-Fi, TCP/IP, or similar) is a useful plus.
This role is preferably based in hybrid work arrangement in Akron, Ohio. Remote candidates will also be considered. Legal authorization to work in the US is required.

• Design, develop, and maintain firmware for Wi-Fi radio subsystems, including MAC/PHY interfacing, calibration routines, and channel/RF management.
• Bring up Wi-Fi silicon on new hardware platforms: port and validate vendor SDKs, drivers, and radio calibration data for new designs.
• Develop and maintain radio firmware within an RTOS environment (e.g., ThreadX or similar) and host-side Wi-Fi drivers under Linux, with real-time scheduling, interrupt handling, and register-level access to radio and host interfaces (SDIO, PCIe, USB, DMA).
• Write clean, well-documented, testable code following Ezurio coding standards and secure development practices.
• Support 802.11 protocol-layer behavior (association, authentication, power-save, rate adaptation) and power management/wake-on-wireless design in coordination with vendor stacks.

• Debug complex RF firmware issues using tools such on hardware where on-device debug access (e.g., JTAG/debug ports) is limited, using debug output, code analysis, logic analyzers, oscilloscopes, and Wi-Fi packet capture tools (e.g., Wireshark) and JTAG/SWD
• Develop and execute unit, functional, integration, and system-level tests; work with SWQA teams to contribute to test infrastructure and CI/CD pipelines.
• Reproduce, isolate, and resolve field and customer-reported Wi-Fi issues (throughput, roaming, association drops, coexistence) and drive issues to root cause and closure.
• Participate in code reviews and enforce quality gates across the software development lifecycle.

• Partner with the RF hardware team (USA and Taiwan) during schematic review, antenna design, and prototype bring-up to flag firmware-relevant design considerations early.
• Work directly with customers and program managers to clarify Wi-Fi firmware requirements, scope, and acceptance criteria for co-development programs.
• Support manufacturing, NPI, and DVT/PVT activities with RF test tools, calibration procedures, and production-line firmware as needed.
• Provide clear technical status updates to program managers and contribute to schedule and risk discussions.

• Produce and maintain technical documentation: design specifications, API references, porting guides, and release notes.
• Maintain source control hygiene, branching strategy, and release/versioning discipline across active programs.
• Contribute to the continuous improvement of embedded software development practices within the Custom SOM & SBC group.

• Strong proficiency in C working in embedded, memory-constrained, real-time systems.
• Solid understanding of processor architecture, memory management, and real-time constraints in embedded systems and working with register access.
• Proven debugging skills across the hardware/software boundary, using debug output, JTAG/SWD, oscilloscopes, logic analyzers, and ideally Wi-Fi packet capture tools.
• Demonstrated persistence and rigor in debugging and driving issues to true root cause rather than applying surface-level fixes.
• Ability to read schematics and datasheets, and to communicate effectively with RF hardware engineers on radio and interface details.
• Strong written and verbal communication…
