Principal ASIC Engineer (Mixed-Signal)

Job Title

Principal ASIC Engineer (Mixed-Signal)

Role Summary

Lead and establish Voyant's custom mixed-signal ASIC program. This hands-on role will architect the ASIC strategy, select tools and processes, deliver analog and mixed-signal silicon that interfaces with photonic ICs, and grow a small IC design team.

Initial work is primarily IC design (>80%); the role includes a clear path to technical leadership and team management as the organization scales.

Experience Level

Senior - requires 7+ years of relevant analog and mixed-signal IC design experience.

Responsibilities

The principal responsibilities include:

• Drive analog and mixed-signal tapeouts from concept through production across multiple technology nodes (including 130 nm and below, and BCD processes).
• Design ultra-low-noise transimpedance amplifiers (TIAs) and other precision front-end analog circuits.
• Develop mixed-signal blocks (amplifiers, ADCs, DACs, bias and power-management circuits) that interface directly with photonic ICs.
• Establish the ASIC development environment: select EDA tools, define design flows, and set verification and validation standards.
• Collaborate with photonics designers, systems engineers, and FPGA/digital teams to ensure seamless co-design and integration.
• Provide HDL and architectural input to external digital design partners.
• Hire, mentor, and grow a small team of analog and digital IC designers.
• Define and oversee test plans for OSAT-level validation and manufacturability.

Requirements

Must-have qualifications:

• 7+ years in analog and mixed-signal IC design with an ~80/20 analog-to-digital focus.
• Proven track record leading multiple tapeouts from concept to production silicon.
• Deep expertise in low-noise analog circuit design, particularly TIAs or similar precision front-ends.
• Strong understanding of mixed-signal components: ADCs, DACs, bias circuits, and power management.
• Experience developing test plans and working with OSAT partners for analog ASIC validation.
• Experience interfacing analog designs with advanced-node digital design flows.
• Ability to deliver working silicon within a 9–12 month timeframe and strong cross-disciplinary communication skills.

Nice-to-have:

• Experience with photonic IC co-design or interfacing analog circuits with optical components.
• Knowledge of advanced packaging techniques (chiplets, heterogeneous integration, 2.5D/3D) and design-for-manufacturability.
• Familiarity with commercial IP ecosystems, build-vs-buy tradeoffs, and license selection.

Education Requirements
