Senior Mixed Signal ASIC Engineer

Introduction Ayo is a venture-backed early-stage startup that will radically re-define how humanity performs compute for AI. Our photonic processors will provide orders of magnitude improvement in speed and power efficiency in comparison to conventional digital compute platforms by taking advantage of the natural parallelism, speed and energy efficiency of light. We are seeking a Senior Mixed Signal ASIC Engineer to serve as a core team member and among the first employees at Ayo. Reporting to our Mixed Signal ASIC Lead, you will play a hands-on role in designing, taping out, and testing the electronic ASICs that interface with Ayo’s photonic integrated circuits. You will work collaboratively across functions to co-design and co-package electronic ASICs with Ayo’s photonic chips, support bring-up and test, and contribute to successful demonstrations and product prototypes. Responsibilities: Contribute to the architecture and specification of mixed-signal ASICs that control and interface with Ayo’s photonic integrated circuitsPerform schematic capture, layout, and verification for mixed-signal integrated circuits with elements including digital-to-analog converters, analog-to-digital converters, transimpedance amplifiers, and transconductance amplifiersExecute across the full design-to-test cycle: design, manufacture, bring-up, characterization, and validationSupport packaging and test requirements and flows for integrated circuitsContribute to the bring-up and test of integrated circuitsProvide expertise and support to other Ayo team membersBe interested, curious, and willing to take on the full scope of ASIC development Qualifications: PhD in electrical engineering or equivalent industry experience 5+ years of experience designing, simulating, and testing analog and mixed signal integrated circuitsStrong fundamentals in analog and mixed signal design, including ADC/DAC, amplifiers (TIA, OTA), and related circuit blocksCommercial tape-outs preferred; strong hands-on foundry experience requiredProficiency with standard EDA tools such as Cadence or SynopsysDemonstrated ability to take a chip from design through manufacture, test, and validation Preferred Qualifications: Experience collaborating with integrated photonics teamsExperience with advanced packaging such as 2.5D / 3D integration
