Confirmed on the employer's own hiring board on Oct 16, 2026. First seen by Alion on Jul 29, 2026. Amazon scores A on the Alion truth index.
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
Basic qualifications
- Bachelor's 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
Preferred qualifications
- 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
