Silicon and Foundry Operations

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.

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.

• 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

• 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

• 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

• 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

• 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
