Physical Design & Timing Closure Engineer (ASIC)

1. Job Description

You will drive synthesis, place-and-route (P&R), clock tree synthesis (CTS), and static timing analysis (STA) closure for Tashkian Semiconductor’s tape-out ready silicon IP across leading foundry nodes (TSMC, GlobalFoundries, Intel Foundry).

This is about delivering synthesizable collateral and sign-off quality GDSII layouts that achieve >800 MHz performance under strict power budgets.

You will work side by side with RTL designers to optimize floorplanning, manage multi-voltage domains (UPF), and enforce Domain-Oriented Masking layout rules.

2. Key Responsibilities

  • Execute full physical design flow from synthesized gate-level netlist to tape-out clean GDSII collateral.

  • Achieve timing closure at >800 MHz across multiple PVT corners, addressing signal integrity (SI) and EM/IR drop analysis.

  • Collaborate with RTL architects on floorplanning, power grid distribution, and Domain-Oriented Masking physical layout constraints.

  • Improve reliability, consistency, and performance of AI outputs

  • Build systems that scale from simple use cases to complex workflows

  • Collaborate with designers to make complex systems feel simple

  • Ship fast, iterate often, and refine based on real usage

3. Qualifications

Must-have:

  • Strong engineering fundamentals (frontend, backend, or fullstack)

  • Experience building and shipping real products or features

  • Comfortable working with APIs, data processing, and system design

  • Familiarity with AI tools, LLMs, or AI-powered workflows

  • Ability to think in systems — not just isolated features

  • Strong product sense — you care about usability and outcomes

Nice-to-have:

  • Experience building AI-powered products or integrating AI into existing systems

  • Familiarity with prompt design, evaluation, or output structuring

  • Experience with workflow automation or orchestration systems

4. Benefits

  • Competitive equity — join as an early technical founder and own part of what you build.

  • Work from anywhere with flexible hours.

  • Unlimited PTO and mental health days.

  • Annual learning & development budget.

  • Top-tier equipment and software tools.

  • Direct collaboration with founders and product leadership.

  • Opportunity to shape product, tech stack, and company culture from day one.
