Job Description

Company Overview: Ambiq has been on a singular mission since 2010 to put intelligence everywhere by creating the most energy-efficient semiconductor solutions for IoT endpoint devices. Using the revolutionary Subthreshold Power Optimized Technology (SPOT®) Platform, Ambiq's record-breaking ultra-low power solutions, including MCU and SoCs, have helped global device makers deliver more than 150 million products with advanced features, enhanced performance, and extended battery life. With a leading market share in wearables at the speed of shipping 1 million units per month, Ambiq is now expanding its impact on novel endpoint products such as hearables, smart home automation, industrial IoT preventive monitoring, and more. 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, above all, 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, interesting, and challenging projects that will create a lasting impact. Come join us on our quest for 100 billion devices. The endpoint intelligence revolution starts here.
Specific Responsibilities

• Chip level and block level spec definition
• Circuit architectural design and verification
• Transistor level analog IC circuit design and verification
• Directly conduct or closely supervise the analog circuit layout
• Conduct design reviews and resolve action items generated as a result of these reviews
• Attend design reviews to provide input and guidance to other designers
• Work with digital designers to interface with and verify analog circuit block
• Assist in prototype chip testing to validate analog circuit blocks
• Develop and implement a manufacturing test plan for analog circuit blocks; support efficient test program development
• Support marketing in product definition
• Support product engineering to meet manufacturing/production needs
• Support applications engineering to meet customer needs

Experience Required The qualified candidate should be an engineer with experience developing advanced analog/mixed-signal circuits. Experience should include high-level modeling, spec definition, transistor level design, layout, test, evaluation, and debugging of prototype ICs. The ideal candidate will have a strong intuitive and analytical understanding of transistor-level design including stability, matching, transient and noise analysis, low power design trade-offs, and architectural and systems issues. A deep knowledge of transistor operation in the subthreshold regime is highly desirable. The analog IC design engineer must work extensively with digital, applications, and product engineers, so a familiarity with digital, lab, and product test issues is highly desirable. Key Qualifications

• Master's degree or equivalent training in related field and 10+ years of related experience. An advanced degree (e.g., PhD) may reduce the minimum experience required.
• Experience in the full design flow, from specification to circuit design/verification to prototype testing to high volume production support
• Experience in top level verification, integration of IP blocks, LVS, DRC, FILL and tape out experience desirable.
• Experience designing various analog circuits including voltage regulators, voltage reference generators, analog-to-digital converters, crystal oscillators, and DC-DC converters
• Experience with IO and ESD is extremely desirable
• Solid background in semiconductor physics and signal processing
• Experience designing subthreshold-biased or ultra-low power analog circuits is extremely desirable
• Experience with mixed mode simulators and Verilog-ams is extremely desirable
• Experience working with a team of analog and digital designers in a mixed-signal environment
• Experience guiding layout trade-offs for performance and size
• Experience designing analog circuits for testability using special test modes, production trimming, etc.
