About Tylsemi Tylsemi is building and scaling high-impact semiconductor operations. We partner across design, manufacturing, and supply chain to bring silicon from concept to high-volume production with speed, quality, and predictable execution. Role Overview As Silicon and Foundry Operations, you will own the operational backbone of Tylsemi’s silicon execution - from foundry engagement and tapeout readiness through wafer production, yield ramp, and delivery. This is a high-ownership leadership role for a seasoned operator (15 years+) who thrives in ambiguity, drives cross-functional alignment, and builds durable processes that scale across programs and manufacturing partners. What You’ll Do
- Own end-to-end silicon operations across multiple programs: planning, execution cadence, risk management, and delivery commitments
- Lead foundry and OSAT operational engagement: capacity planning, build plans, WIP visibility, cycle time, and on-time delivery
- Drive tapeout-to-silicon readiness: ensure PDK/flow readiness, signoff checklists, release governance, and cross-functional alignment (Design, PD, DFT, CAD, Packaging, Test, Quality, Supply Chain)
- Establish and run operating rhythms (weekly exec reviews, build readiness reviews, yield reviews, postmortems) with crisp metrics and follow-through
- Own yield ramp operations: coordinate debug priorities, lot disposition, excursion response, and corrective/preventive actions with internal teams and manufacturing partners
- Build scalable program dashboards and reporting for schedule, cost, yield, quality, and supply risk; provide clear executive communication on tradeoffs and decisions
- Manage change control across masks, process nodes, packaging, test flows, and BOM; ensure documentation and traceability
- Partner with procurement and finance on wafer pricing, NRE/mask costs, and contract terms; support negotiations with data-driven operational inputs
- Develop contingency plans for supply constraints (capacity, materials, tooling) and execute mitigation strategies to protect customer and internal milestones
- Mentor and develop a small team over time; set high standards for accountability, clarity, and operational excellence
What We’re Looking For
- 15–30 years of experience in semiconductor operations spanning foundry manufacturing, silicon program management, supply chain, yield/quality, or related roles
- Deep familiarity with the foundry ecosystem and the tapeout-to-HVM lifecycle (masking, wafer starts, probe, assembly, final test, qualification, ramp)
- Proven ability to lead cross-functional execution across engineering and manufacturing partners, including senior stakeholder management
- Strong operational judgment: ability to prioritize, simplify complex situations, and drive decisions under schedule and supply pressure
- Track record of building scalable processes, metrics, and governance that improve predictability and execution quality
- Excellent communication skills - clear executive updates, crisp documentation, and strong meeting leadership
Required Skills
- Foundry operations and partner management
- Silicon program execution (tapeout through production ramp)
- Capacity planning, build planning, and WIP/cycle-time management
- Yield ramp operations and manufacturing issue/excursion management
- Cross-functional leadership and executive communication
- Metrics, dashboards, and operational governance
Nice to Have
- Experience across multiple process nodes and packaging technologies (advanced packaging, chiplets, 2.5D/3D, HBM integration)
- Background in quality systems (8D, CAPA, SPC) and customer qualification/PPAP-style readiness
- Experience scaling operations in a fast-growing company or bringing new products from first silicon to high-volume production
- Global manufacturing experience across multiple regions and time zones
Success in This Role Looks Like
- Predictable tapeout-to-silicon execution with clear readiness gates and minimal last-minute surprises
- Strong visibility into supply, schedule, yield, and cost - paired with fast, effective mitigation when risks emerge
- Improving yield and cycle time through disciplined reviews, crisp ownership, and rapid closure of actions
- Trusted, high-leverage partnerships with foundries/OSATs that translate into reliable delivery and scalable capacity
- A durable operating cadence that keeps teams aligned and programs on track as Tylsemi scales
