Chief Staff Digital Innovation Jobs (NOW HIRING)

Staff Digital Design Engineer – SOC Low Power, Clocking & Integration (Austin, TX)

The Role as a Staff Digital Design Engineer, you will develop world‑class, highly integrated, low‑power, System‑on‑Chip device to serve the IoT wireless market.

• Develop complex SOC/chip architectures with multiple processors, digital and mixed signal subsystems, multiple power, and clock domains with a goal towards optimizing power for specific customer scenarios
• Define and implement SoC‑level low‑power architecture, including power domains, retention, isolation, level shifters, and power sequencing
• Develop and integrate UPF/CPF‑based power intent across subsystem and SoC hierarchies
• Collaborate with architects to define power‑management strategies that meet performance, power, and area targets
• Design and integrate clocking infrastructure, including clock generation, clock distribution, clock gating, clock muxing, reset architectures, and clock monitoring mechanisms
• Drive RTL design and integration of power‑management controllers, clock controllers, reset controllers, and related infrastructure IPs
• Prepare and hold architecture, design, and verification reviews with technical staff throughout project lifecycle
• Analyze and debug low‑power and clocking issues identified during simulation, emulation, synthesis, and silicon bring‑up
• Architect and integrate SoC interconnects and bus fabrics, including AXI, AHB, APB, and other on‑chip communication protocols
• Lead small teams of design engineers to architect, design and verify digital subsystems
• Drive subsystem and SoC integration activities, ensuring seamless connectivity between processors, memories, peripherals, accelerators, and third‑party IPs
• Drive RTL development and integration of infrastructure IPs, including clock controllers, reset controllers, power‑management controllers, DMA engines, and bus fabric components
• Analyze and debug integration, clocking, power, CDC/RDC, and protocol‑related issues throughout the development cycle
• Validate/bring‑up designs on silicon, providing support to cross‑functional teams

BS/MS in Electrical Engineering and 10‑20 years of professional experience in digital CMOS IC design

• Demonstrated ability to lead small teams designing complex digital subsystems
• Strong RTL design expertise using Verilog/System Verilog
• Solid understanding of SoC clocking architectures, clock domain crossing (CDC), reset domain crossing (RDC), synchronization techniques, and timing considerations
• Extensive experience with low‑power design methodologies, including UPF, power gating, retention, isolation, level shifting, and power‑aware verification
• Strong experience with industry‑standard on‑chip bus protocols such as AXI, AHB, APB, and related interconnect architectures
• Experience integrating complex subsystems, processor clusters, memory subsystems, and third‑party IPs into large SoCs
• Knowledge of embedded processor systems and C coding
• Experience with logic simulators for both RTL and gate‑level simulation, design/waveform browsers, and power analysis tools
• Experience with logic synthesis and timing constraints
• Experience working with backend team to optimize design for power, performance, and area
• Experience working with analog and mixed signal designs, to support design integration and verification of these subsystems in SOC
• Experience with scripting and automation; knowledge of Python, Perl, and Tcl
• Experience with revision control and configuration management systems (such as Perforce, Git, Methodics)
• Excellent written and verbal communication skills
• Demonstrated ability to generate high output in a self‑driven manner
• Experience with artificial intelligence (AI)‑powered tools and technologies used to enhance productivity, analysis, and decision‑making

• Great medical (Choice of PPO or Consumer Driven Health Plan with HSA), dental and vision plans
• Highly competitive salary
• 401(k) plan with match and Roth plan option
• Equity rewards (RSUs)
• Life/AD&D and disability coverage
• Flexible spending accounts
• Adoption assistance
• Back‑up childcare
• Commuter benefits, legal benefits, pet insurance
• Flexible PTO schedule
• 3 paid volunteer days per year
• Charitable contribution match
• Tuition reimbursement
