Position Title: Staff Memory Design Engineer
Reporting to: Director of Analog IC Design
Location: Austin, TX
Ambiq Micro is a fabless semiconductor company based in Austin, TX developing the world’s most energy efficient integrated circuits for electronic devices with multi-month, multi-year, and multi-decade battery lives. Using technology originally invented by leading low power circuit researchers at the University of Michigan, Ambiq is developing a series of ultra-low power products on the Subthreshold Power Optimized Technology (SPOT) Platform. The company’s first product is the world’s most energy-efficient real-time clock and has gained significant customer traction to date. The company’s next product will be the first in a line of ultra-low power ARM Cortex-based microcontrollers. Key markets include wearables, smart cards, wireless sensors, watches, medical devices, and a wide variety of other wireless devices. Ambiq has adopted a customer-focused approach and will evolve its product line according to the needs of customers seeking to develop smaller, less expensive products with longer battery life.
The Ambiq team includes low power experts and industry veterans and is growing quickly. New team members will join an evolving and exciting environment that values technology-based innovation, adaptation, and, above all, an enthusiasm for energy efficiency.
Scope and Responsibilities
The Staff Memory Design Engineer is responsible for specifying, designing, and verifying various ultralow power memory components in Ambiq Micro’s family of mixed-signal energy-efficient semiconductor devices. Key focus initially will be placed on the flash/SRAM memory arrays including sense amps, word line drivers, column drivers, and other blocks. As part of a small but growing startup team, the designer will participate in all aspects of chip development, from initial design specification through volume manufacturing.
- Chip level and block level spec definition with a particular focus on memory arrays
- Circuit architectural design and verification with a particular focus on memory arrays
- Transistor level 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 other designers to interface with and verify memory circuits
- Assist in prototype chip testing to validate memory circuit blocks
- Develop and implement a manufacturing test plan for the memory blocks; support efficient test program development
- Support the Operation team in building a comprehensive memory qualification flow
- Support marketing in product definition
- Support applications engineering to meet customer needs
The qualified candidate should be an engineer with 10+ years of proven experience in memory designs . Experience should include overall memory array architecture, high-level modeling, spec definition, transistor level design, layout, test, validation and debugging of prototype ICs. Additionally, the candidate is expected to have rich experience in bringing memory products into volume production and to have a thorough understanding of the details and nuances of verification and qualification of the memory products/circuits. 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 sub-threshold regime is highly desirable.
- Master’s degree or equivalent training in related field and 10+ years of related experience in memory circuit designs. 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 designing various memory circuits including sense amps, line drivers as well as the basic analog circuit blocks including bandgaps, op amps, etc.
- Solid background in semiconductor physics and signal processing
- Experience designing subthreshold-biased or ultra-low power analog circuits 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 in the verification and qualification of memory designs
Key Personal and Professional Attributes
Ambiq Micro management is building a company that values continued technology innovation, a fanatical attention to customer needs, collaborative decision making, and, above all, enthusiasm for energy efficiency. Besides embracing these same values, the qualified candidate must be self-motivated, extremely creative, and should be comfortable learning exciting new technologies. This is an opportunity for growth and an opportunity to work on complex, interesting, and challenging projects.
