Principal ASIC Engineer [Mixed-Signal]

Voyant Photonics is seeking a Principal Mixed-Signal ASIC Engineer to lead the development of custom ICs for silicon photonic chips. This role offers a unique opportunity to shape the ASIC strategy and build a team while working on cutting-edge technology for applications in robotics, autonomy, and AI data centers.

Responsibilities

• Drive analog tapeouts from concept to production across various technology nodes (130 nm and below)
• Design ultra-low-noise transimpedance amplifiers (TIAs) with low pA/Hz noise performance
• Develop mixed-signal circuits including amplifiers, ADCs, DACs, and power management blocks interfacing with photonic ICs
• Establish the ASIC development environment by selecting EDA tools, defining design flows, and setting verification standards
• Collaborate with photonics designers, systems engineers, and FPGA/digital design teams for seamless co-design
• Provide HDL and architectural input to external digital design partners
• Hire and mentor a small team of analog and digital IC designers

Qualifications

• 7+ years of experience in analog and mixed-signal IC design with an 80/20 analog-to-digital focus
• Proven track record of leading multiple tapeouts from concept to production silicon
• Deep expertise in low-noise analog circuit design, particularly TIAs or similar precision circuits
• Knowledge of test plan development for analog ASICs at OSAT partners
• Strong understanding of mixed-signal design including ADCs, DACs, bias circuits, and power management
• Experience in both mature nodes and interfacing with advanced node digital design
• Ability to deliver working silicon within 9-12 months
• Excellent communication and collaboration skills

Skills

• Experience with photonic IC co-design or interfacing analog circuits with optical components
• Knowledge of advanced packaging techniques (chiplets, heterogeneous integration, 2.5D/3D)
• Background in design-for-manufacturability
• Understanding of commercial IP ecosystems and license negotiation
