Role Summary

We are looking for an Embedded Firmware Engineer to join our core Embedded Systems team developing next-generation UniFi gateways and wireless platforms. In this role, you’ll collaborate with cross-functional teams to design, develop, and optimize low-level firmware for high-performance, reliable networking devices.

You will contribute across the entire product lifecycle, from board bring-up and BSP integration to performance tuning, feature enablement, and production readiness. Your work will have direct impact on system stability, wireless performance, thermal management, and overall user experience in large-scale, real-world deployments.

If you’re passionate about working close to the hardware, taking ownership of critical embedded components, and solving complex problems in constrained, real-time environments, we’d love to hear from you.

Join us to build robust, scalable, and innovative firmware powering millions of connected devices worldwide.
 

Responsibilities

• Lead the development and maintenance of embedded firmware for Wi-Fi systems and networking devices.
• Bring up new platforms, including bootloader configuration, BSP integration, and Wi-Fi chipset enablement.
• Collaborate with hardware, RF, QA, cloud/backend, and manufacturing teams to deliver production-ready firmware.
• Debug low-level system issues using kernel logs, tracing tools, and lab diagnostics.
• Optimize performance across CPU, memory, thermal, and wireless subsystems.
• Support factory processes through diagnostic tools, recovery flows, and upgrade mechanisms.
• Drive improvements in firmware stability, reliability, and long-term maintainability.
• Contribute to architectural discussions and feature planning across multiple product lines.

Requirements

• Proven experience developing embedded firmware in C/C++ for Linux or RTOS-based systems
• Strong foundation in embedded systems, with 3+ years of hands-on experience in board bring-up, driver integration, or SoC-level debugging
• Solid understanding of 802.11 protocols, MAC/PHY layers, and Wi-Fi system behavior in real-world deployments
• Familiarity with kernel space vs user space concepts, memory management, and interrupt handling
• Experience using tools like dmesg, perf, strace, JTAG, or logic analyzers to debug complex firmware issues
• Ability to read schematics and work closely with hardware teams on platform-level bring-up
• Bachelor's or Master’s degree in Computer Engineering, Electrical Engineering, or related fields
• Clear communication skills and a strong sense of ownership in delivering production-quality code. 
• Good command of English, both written and spoken.

Nice to have

• Experience working on Wi-Fi firmware, wireless driver stacks, or connectivity products in production environments
• Familiarity with Qualcomm Atheros (QCA) SDKs, OpenWRT, Debian or embedded Linux distributions
• Background in optimizing wireless performance across complex RF environments
• Hands-on experience with BLE, thermal control, or secure boot implementations
• Leadership in cross-functional debug efforts involving hardware, RF, and backend systems
• Strong ownership mindset, with the ability to work independently and deliver in fast-paced, ambiguous situations
• Proficient with Git and other source code management tools
• Contributions to open-source firmware or kernel projects are a plus
