Job summary

MediaTek in Austin, TX seeks a Senior STA Engineer to own block‑level sign‑off, drive timing and power ECOs, and partner with PD RTL and DFT teams to ensure clean sign‑off for next‑gen SoCs.

You will develop advanced margining methodologies, analyze clock trees, and deliver ETM/Hyperscale timing models while contributing to MediaTek's global STA forums and margin strategy.

Qualifications

• 5+ years of STA experience on high‑performance CPU designs.
• Expert-level understanding of multi-scenario STA and SDC constraints.
• Deep knowledge of margining (OCV/AOCV/POCV) and silicon correlation.
• Multi-OPP closure across wide voltage‑frequency ranges.
• Familiarity with clock tree timing analysis and PD/RTL/DFT coordination.
• Experience creating custom timing closure and power‑recovery recipes.
• Low‑power design knowledge including CPF/UPF multi‑voltage islands.
• Proficiency with Cadence Tempus and/or Synopsys PrimeTime.

Responsibilities

• Own block-level STA sign-off: constraint development and timing closure
• Generate and drive timing/power ECOs through resolution
• Collaborate with RTL and DFT for accurate constraints

As a trusted partner to the world's leading brands, we are committed to ensuring access to world‑class technology for everyone. Our dedication to accelerating AI underscores our mission to enrich the future of humanity.

About the Role

Mobile CPUs push timing sign‑off to its limits — ultra‑wide voltage ranges, aggressive multi‑OPP targets, and sub‑2 nm parasitics demand creative margin methodology. As a Senior STA Engineer you will be the timing authority for one or more CPU blocks, partnering with PD, RTL, and DFT teams to deliver clean sign‑off on MediaTek's next‑generation SoCs.

What You'll Do

• Own block‑level STA sign‑off: constraint development, multi‑scenario regression, and timing closure
• Generate and drive timing and power ECOs through to resolution
• Partner with RTL and DFT teams to define accurate functional and test‑mode constraints
• Develop and champion advanced margining methodologies (AOCV/POCV) calibrated to silicon
• Analyze clock tree quality; guide physical implementation toward scalable, convergence‑friendly CTS
• Build custom sign‑off recipes for power recovery and timing closure in Tempus/PrimeTime
• Deliver timing models (ETM, Hyperscale) and SDC/timing budgets for SoC integration
• Participate in MediaTek's worldwide STA forum; help define next‑generation margin methodologies

Main Requirements and Qualifications

• 5+ years of STA experience on high‑performance CPU designs (≥ 2 GHz)
• Expert‑level understanding of multi‑scenario STA, SDC constraints, and timing exceptions
• Deep knowledge of OCV/AOCV/POCV margining and silicon correlation
• Multi‑OPP closure experience: resolving setup/hold conflicts across a wide voltage‑frequency range
• Familiarity with clock tree timing analysis and co‑optimization with physical design
• Experience developing custom timing closure and power‑recovery recipes in sign‑off tools
• Low‑power design knowledge including CPF/UPF multi‑voltage island methodology
• Proficiency with Cadence Tempus and/or Synopsys PrimeTime
• Strong scripting skills in Tcl, Python, or Perl
• Advanced‑node tape‑out experience (7 nm or below)
• Nice to Have
• ARM Cortex‑A or custom CPU STA experience
• Familiarity with physical design flows (synthesis, place‑and‑route, physical verification)
• IR drop analysis (static and dynamic)

Salary Range

$152,400 - $217,200 annually. Employee may be eligible for performance bonus, short and long‑term incentive programs. Actual total compensation will be dependent upon the individual's skills, experience and qualifications.

Benefits

MediaTek provides a variety of benefits including comprehensive health insurance coverage, life and disability insurance, savings plan, company‑paid holidays, paid time off (PTO), parental leave, 401(k) and more.
