Semiconductors
Responsibilities
Lead the digital design and verification effort for Olix’s ASICs, from architecture through tape-out
Define and partition digital subsystems (compute cores, data movement, control, and high-speed interfaces)
Drive the development of RTL, synthesis, timing closure, and DFT methodologies for next-generation optical compute devices
Coordinate closely with analog, mixed-signal, photonics, packaging, and firmware teams to integrate full-stack system functionality
Build, mentor, and grow a high-performing digital design team; set technical standards and review critical design work
Collaborate with EDA partners, foundries, and external IP vendors to ensure schedule and quality targets are met
Establish and manage verification plans, regression infrastructure, and bring-up/test hand-off
Own key technical decisions around power domains, clocking architecture, data paths, and testability
Contribute directly to strategic program planning, MPW/test-chip execution, and silicon bring-up
Qualification
Required
15 + years experience in digital ASIC design and verification, with at least 3+ full-cycle chips successfully taped out at ≤ 22 nm
Demonstrated track record managing managers and multi‑disciplinary teams (high speed analog, digital, verification, physical design, test)
Proven ability to lead teams through RTL architecture, design, verification, synthesis, and timing closure
Deep understanding of high‑speed mixed‑signal design challenges—multi‑lane SerDes, fast‑settling DACs/ADCs, sub‑picosecond clocking, advanced power‑delivery and packaging
Proven success negotiating foundry schedules, MPW slots, mask‑set revisions and yield‑improvement plans with Tier‑1 fabs (TSMC, Samsung, GF, UMC, etc.)
Strong cross-disciplinary communication and program-management instincts — able to drive execution across multiple domains
Comfort with startup-pace environments where iteration speed and ownership matter more than bureaucracy and alignment with 5-days in-office culture
