• Own the BLE Stack: Architect, implement, and maintain the Bluetooth connectivity layer across our Pod ecosystem. Define GATT services, characteristics, and connection strategies that deliver reliable, secure, and power-efficient communication. • Optimize for Always-On Devices: Drive radio-on time, advertising intervals, connection parameters, and PHY selection while maintaining low-latency sync of biometric data. • Ensure Bulletproof Interoperability: Deliver a connectivity experience that "just works" across the long tail of iOS and Android devices, OS versions, and real-world RF environments. Use sniffers, protocol analyzers, and on-device telemetry to root-cause cross-stack issues with mobile and Pod gateway teams. • Ship and Sustain OTA at Scale: Design and harden the secure OTA DFU pipeline so we can confidently push firmware to a global fleet of devices with low friction and zero bricks. • Bring Up New Silicon: Partner with hardware teams on board bring-up, antenna tuning, regulatory certification (FCC/CE/Bluetooth SIG qualification), and silicon-vendor stack integration for our Nordic-based platform. • Global Collaboration: Work closely with our manufacturing partners in China to develop RF and BLE production tests, ensuring we ship high-quality, fully-validated devices on time. • Effective Remote Communication: Thrive in a hybrid in-person and remote work environment, ensuring clear and impactful communication across firmware, mobile, hardware, and ML teams.

• Lead the full lifecycle of complex multi-layer PCB design (from initial technical specifications to mass production release) with minimum board design cycles. • Develop schematics design for CPUs, high-performance Marvell packet processors, and system-on-chip (SoC) architectures. • Design and integrate high-speed digital interfaces: SerDes, PCI-e, Ethernet, DDR2/3/4, and MII/GMII. • Manage service and management interfaces including I2C, SMI, and SPI. • Design and calculate robust power circuitry, including high-efficiency DC/DC converters and Power Integrity (PI) management. • Provide layout support and strict guidelines for PCB Layout Designers, ensuring top-tier Signal Integrity (SI). • Conduct laboratory bring-up, hardware debugging, validation, and testing using professional equipment (Oscilloscopes, Signal Generators, Power Analyzers).

• Develops and maintains the embedded software for optical transceivers • Writing, debugging, and testing firmware for optical transceivers • Collaborating with hardware engineers to ensure the firmware works seamlessly with the transceiver's hardware • Thoroughly testing firmware to ensure it meets performance and reliability requirements • Optimizing firmware for speed, efficiency, and power consumption • Maintaining detailed documentation of firmware code and functionality
