Advanced Power Integrity & Power Delivery Architect

Rivian is on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.

As a company, we constantly challenge what's possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.

We are seeking a highly skilled and motivated Power Integrity & Power Architecture
Engineer to lead the end-to-end design, modeling, simulation, and post-silicon
validation of advanced SoC power delivery architectures. In this role, you will bridge the
gap between System-on-Chip (SoC) design, power architecture, silicon packaging, and
system-level power integrity

Power delivery architecture, Design & Simulation
* Power Delivery Network (PDN) & Architecture: Define and optimize overall
SoC power architecture, establishing target impedance, transient droop
specifications, and efficiency targets across the full path: SoC/Packaging/Board.
* Advanced Power Supplier Architecture: Define requirements and simulation
flows for next-generation power supplier architectures, such as IVRs, integrated
switching regulators. Co-optimize power delivery for high efficiency, low supply
ripple, tight transient droop targets, and strict thermal limits across the SoC,
package and system.
* SoC Integration: Perform co-design and co-optimization for silicon packaging,
interposers, embedded passives to ensure robust power integrity.
* Multi-Domain Modeling: Conduct pre- and post-layout power integrity (PI),
signal integrity (SI), and IR/droop simulations using industry-standard 2.5D/3D
field solvers and circuit simulators.
Power integrity Validation
* Post-Silicon Bring-up & Correlation: Lead post-silicon validation and silicon
power integrity measurements (micro-probing, high-frequency VNAs, transient
load steppers, real-time scope measurements for PDN noise) to correlate lab
data with pre-silicon simulation models.
* System & Platform Validation: Collaborate with hardware and SoC bring-up
teams to validate SoC platforms under real-world dynamic workloads, verifying
transient performance, decoupling strategies, and power delivery margins.
Methodology
* Automation & Flow Optimization: Work alongside CAD and tool teams to
automate power integrity analysis, extraction workflows, and simulation scripts
(Python, Tcl, SKILL).

* Education: Bachelor's, Master's, or Ph.D. in Electrical Engineering, Computer
Engineering, or a related field.
* Experience: Proven industry experience in Power Integrity (PI), Power
Architecture for SoCs and advanced 2.5D/3D/MCM packaging.
* SoC Packaging: Deep understanding of System-on-Chip (SoC) power
distribution, package stack-ups, bump/ball maps, and silicon-package
interactions.
* Simulation & Tool Expertise:
EM & Extraction: Ansys HFSS, SIwave, Cadence Sigrity/Voltus-Fi, or
Keysight ADS.
Circuit & PDN Simulation: HSPICE, Spectre, ADS, or SIMPLIS/SIMetrix.
* Post-Silicon Validation Capabilities: Hands-on expertise with high-speed lab
equipment (VNAs, oscilloscopes, active probes, impedance analyzers, load
steppers) for physical power validation and PDN characterization.
* Fundamentals: Strong foundation in power architecture, electromagnetics,
transmission line theory, s-parameters, and power distribution network (PDN)
noise dynamics.
Preferred Skills:
* Automation & Scripting: Proficiency in Python, Tcl, Perl, or Cadence SKILL for
automating simulation and extraction pipelines.
* Behavioral Modeling: Experience with Verilog-A, AMS, or SystemC for
macro-level system power modeling.
* Interface Noise Co-Design: Familiarity with high-speed interfaces (e.g., PCIe,
DDR, UCIe, die-to-die interconnects) and mitigating power supply switching
noise impacts on high-speed signals.
