SoC Power Architecture Engineer - Processor Subsystem

Key Responsibilities:

· Define and architect power domains within processor subsystems, including always-on, switchable, and retention domains optimized for low-power use cases

· Design and implement power domain partitioning strategies for subsystems involving embedded processors, bus interconnects, and associated peripherals

· Develop and integrate supporting logic for power domain separation, including power switches, isolation cells, level shifters, and retention registers

· Define and implement power control sequencing and state machines for domain power-up/power-down flows, with emphasis on fast wake-up latency requirements for satellite link windows

· Collaborate with SoC architects, physical design, and verification teams to ensure power domain intent is correctly captured in UPF

· Drive definition of low-power modes (e.g., Sleep, Deep Sleep, Power-Off) and their interaction with system-level power management in battery- or energy-harvesting-powered IoT devices

· Work with processor subsystem reference designs as a baseline and adapt the power architecture to the unique demands of satellite IoT SoCs

· Support power-aware synthesis, place-and-route, and sign-off flows in coordination with the physical design team

· Define and review power intent files (UPF/IEEE 1801) and ensure consistency with RTL implementation

· Engage with verification teams to ensure power domain structures are properly tested and validated across all low-power operating modes

Required Qualifications:

· Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field

· 7+ years of experience in ASIC/SoC design with a strong focus on low-power architecture

· Deep hands-on experience with power domain definition, isolation strategies, and retention architectures

· Proficiency with UPF (IEEE 1801) power intent format

· Strong knowledge of RTL design using SystemVerilog or VHDL

· Demonstrated experience optimizing for ultra-low power consumption in energy-constrained applications such as IoT, wearables, or similar

· Familiarity with low-power synthesis and physical design constraints

Preferred Qualifications:

· Experience with Arm Corstone or similar processor subsystem IP, including Arm processor subsystems (Cortex-M series) or similar embedded processor architectures

· Knowledge of AMBA bus protocols (AHB, APB, AXI) as they relate to power domain crossings

· Experience with power analysis tools (e.g., Synopsys PrimeTime PX, Cadence Joules)

· Understanding of battery-powered and energy-harvesting device constraints as they influence SoC power architecture decisions

· Familiarity with power management ICs (PMICs) and their interface to domain control logic

Additional Requirements

This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
