Sr. Hardware Development Engineer, Device Connectivity

Amazon Lab126 is an inventive research and development company that designs and engineers high-profile consumer electronics.

About the Role
As a Senior Hardware Development Engineer in the systems team you will own next-generation AI-enabled IoT device design and validation delighting our customers with best-in-class quality. You will interact with a versatile team of engineers to design develop validate and launch innovative AI-enabled IoT devices at large scale.

To be successful you need to be highly motivated understand how to solve problems and dive deep while delivering to the highest standards. You are a technical leader on your team. You work efficiently with limited guidance and embrace the challenge of ambiguous situations where product requirements and specifications are not yet fully defined. You take full ownership of the hardware development lifecycle from early concept through mass production and drive cross-functional collaboration to deliver world-class products.

Key job responsibilities
As a Sr. HW Development Engineer you will:

- Lead the end-to-end hardware development lifecycle for Amazon AI-enabled IoT devices from concept definition requirements design prototyping validation through to mass production and sustaining
- Design and develop sensing hardware sub-systems (e.g. load cells IR photoelectric sensors accelerometers humidity/temperature sensors) integrated with wireless connectivity (Wi-Fi BLE GNSS/GPS LTE-M/NB-IoT)
- Define hardware requirements and specifications create design documentation and drive design reviews
- Partner with manufacturing factories (CM/ODM) to drive DFM DFT and production readiness; lead vendor meetings and negotiate appropriate manufacturing approaches
- Develop and execute comprehensive test plans that validate designs perform root cause analysis and drive resolution of hardware issues across development and production phases
- Collaborate cross-functionally with firmware software mechanical product and quality teams to deliver cohesive product solutions

- Bachelors degree in electrical engineering or equivalent
- 7 years of overall experience in design validation troubleshooting and manufacturing in consumer electronics with a track record delivering stable performant hardware solutions meeting cost and quality targets.
- Experience in hardware development for IoT or smart home products with wireless technologies (e.g. Wi-Fi BLE GNSS/GPS) and/or sensing technologies (e.g. load/weight IR accelerometers temperature/humidity).
- Knowledge of processor architecture digital/analog circuit design and various communications protocols such as I2C UART SPI USB MIPI I2S etc.
- Proficiency with EDA tools (OrCAD Altium Allegro etc.) and hands-on lab equipment (oscilloscopes spectrum analyzers logic analyzers signal generators etc.)
- Fluent communication skills in English and Mandarin

- End-to-end product development experience from concept through mass production including manufacturing factory engagement (DFM reviews production line support yield improvement)
- Experience with sensor system design including signal conditioning low-power design and sensor fusion (e.g. combining IMU data with GPS for tracking applications)
- Experience designing battery-powered low-power IoT devices with optimized sleep/wake strategies
- Familiarity with EMI/EMC compliance testing and regulatory certification processes (FCC CE NCC etc.)
- Experience leading cross-site/cross-functional engineering teams with strong vendor management skills across component suppliers and contract manufacturers
