Power Integrity Engineer Jobs: Find PDN Signoff Roles
Power integrity engineers are the last line of defense before a chip goes to silicon. When the PDN (power delivery network) fails to deliver stable voltage at every transistor under all operating conditions, timing failures, functional errors, and reliability problems follow. Getting that wrong costs a respun mask set.
Day-to-day responsibilities include designing and analyzing on-chip power grids, running IR-drop and electromigration (EM) signoff using Ansys RedHawk-SC or Cadence Voltus, and working with physical design teams to resolve PDN weaknesses before tape-out. Interpreting RedHawk heat maps and translating results into concrete grid changes, via fills, or decap additions is core to the role.
Advanced nodes add real constraints. At 5nm and below, tighter current density limits, multi-rail power architectures, and finer metal pitch each increase signoff complexity. Familiarity with parasitic extraction via Synopsys StarRC or Cadence QRC, and an understanding of how extraction settings affect IR-drop results, gives candidates a measurable advantage over those who only know how to run the solver.
Package co-simulation is increasingly expected. As chiplet designs and 2.5D/3D-IC integration become mainstream, power integrity engineers analyze PDN continuity across die-to-die interfaces, through-silicon vias, and heterogeneous package structures, not just the on-chip grid. Tools like Ansys SIwave and Cadence Clarity enter the picture here alongside RedHawk and Voltus.
Qualcomm, Apple Silicon, NVIDIA, and hyperscaler in-house silicon teams are among the most active hirers. AI accelerator startups with aggressive tapeout schedules also recruit regularly at this level. Companies running tape-outs at 7nm and below account for most open roles, and demand for engineers who can handle both chip-level and package-level PDN work remains strong.
Staff-level engineers at large semiconductor companies typically see total compensation well above $200K. For current salary ranges across seniority levels and company types, the salary guide for semiconductor design jobs is a useful reference.

FAQ
What is the difference between power analysis and power integrity engineering?
Power analysis focuses on estimating and optimizing the power consumption of a design, while power integrity engineering focuses on the quality and stability of power delivery to the chip. Power integrity engineers analyze IR-drop and electromigration, ensuring the PDN meets all reliability and performance specifications.
What tools are most important for power integrity engineer jobs?
Ansys RedHawk-SC and Cadence Voltus are the dominant full-chip power integrity tools. For package and system-level PDN co-simulation, tools like Ansys SIwave and Cadence Clarity are also used. Familiarity with extraction tools like StarRC or QRC is a plus.
How is 3D-IC and chiplet packaging changing power integrity engineer jobs?
Chiplet integration introduces new power integrity challenges: managing power delivery across die-to-die interfaces, through-silicon vias, and heterogeneous package structures. Engineers with experience in multi-die PDN co-design are particularly valuable as the industry moves toward disaggregated chip architectures.
