We are seeking a hands-on Senior Firmware Developer with 3 to 8 years of deep technical experience. This is a pure technical track role focused on architecting and implementing complex Bluetooth Dual-mode (BR/EDR & LE) solutions. You will be the technical backbone for our high-end wireless products, bridging the gap between sophisticated BT Legacy protocols and contemporary Embedded GUI systems within a global engineering framework.
Core Technical Focus
Dual-Mode Stack Mastery: Take full ownership of the Bluetooth stack integration. You must have a "under-the-hood" understanding of BT Legacy (Classic) and BLE coexistence, ensuring high stability in complex RF environments.
Hardcore Firmware Engineering: Develop low-latency firmware on RTOS/Bare-metal. You will be responsible for critical path code, memory optimization, and hardware-software co-design.
HMI & Graphics Core: Implement responsive Embedded GUI logic, ensuring that high-refresh-rate UI does not compromise the real-time performance of the Bluetooth radio.
Technical Quality Excellence: Lead by example in Software Quality Control.
You will define and execute rigorous testing frameworks, code-level optimizations, and CI/CD integration to ensure enterprise-grade stability.
Technical Requirements (The "Must-Haves")
Experience: 38 years of individual contributor (IC) experience in firmware development.
Bluetooth Legacy : understanding of BR/EDR stack: L2CAP, RFCOMM, SDP, and Link Manager.
Hands-on experience with profiles: A2DP (SBC/AAC/LDAC), HFP/HSP, AVRCP, and SPP.
Ability to debug protocol-level race conditions and audio synchronization issues.
BLE Expertise: Proficiency in GATT, ATT, and advanced features (High Speed/Long Range, Periodic Advertising).
Embedded Toolchain: Expert C/C++ skills. Skilled experience with logic analyzers, protocol sniffers (Ellisys/Frontline), and JTAG debugging.
Global Collaboration: Proven ability to collaborate with overseas engineering teams on a technical-to-technical level within large-scale projects.
Workflow Proficiency: Experience with Jira for task tracking and Git for complex branching/merging (Gitflow).
