Ambiq is hiring: Staff Validation Engineer, Wireless Radio Lead in Austin
Ambiq, Austin, TX, United States, 78716
Company Overview
Ambiq's mission is to develop the lowest-power semiconductor solutions to enable intelligent devices everywhere by developing the lowest-power semiconductor solutions to drive a more energy-efficient, sustainable, and data-driven world. Ambiq has helped leading manufacturers worldwide develop products that last weeks on a single charge (rather than days), while delivering a maximum feature set in compact industrial designs. Ambiq's goal is to take Artificial Intelligence (AI) where it has never gone before in mobile and portable devices, using Ambiq's advanced ultra-low power system on chip (SoC) solutions. Ambiq has shipped more than 250 million units by 2024. For more information, visit www.ambiq.com .
Our innovative and fast-moving teams of research, development, production, marketing, sales, and operations are spread across several continents, including the US (Austin and San Jose), Taiwan (Hsinchu), China (Shenzhen and Shanghai), Japan (Tokyo), and Singapore. We value continued technology innovation, fanatical attention to customer needs, collaborative decision-making, and enthusiasm for energy efficiency. We embrace candidates who also share these same values. The successful candidate must be self-motivated, creative, and comfortable learning and driving exciting new technologies. We encourage and nurture an environment for growth and opportunities to work on complex, engaging, and challenging projects that will create a lasting impact. Join us on our quest for 100 billion devices. The endpoint intelligence revolution starts here.
Position Overview
The Staff Validation Engineer, Wireless Radio Lead is responsible for leading the development board level validation hardware and software used for silicon validation of Ambiq's Bluetooth classic and Bluetooth low energy IP blocks as well as other wireless radio blocks and related analog subsystems. This includes the development of automated test for controlling custom radio hardware and lab instruments, physical (PHY) interface characterization, radio power profiling, control and monitoring of radio functions, data collection, and report generation. The candidate will also develop and test low power radio embedded microcontroller software for communication to host devices and compliance test equipment.
The candidate for this role is expected to be in the office 5 days a week.
