Principal Mixed Signal RTL Design Engineer

About the role

• Lead the micro-architecture and RTL design for Mixed-Signal chiplet focused on intelligent power optimization solutions for AI and high-performance computing.

What you'll do

• Micro-architect and own toplevel RTL for Mixed-signal chip with analog circuits, micro-controller and other logic functions
• Architect, and implement digital PID / cascade control loops (voltage-mode, current-mode, or hybrid) for high-frequency multi-phase IVRs. 

• Develop micro-architecture and implement RTL for control of mixed-signal circuits

• Translate validated MATLAB/Simulink controller models into production-quality RTL (Verilog / SystemVerilog) using HDL Coder or manual high-quality coding. 

• Design and implement supporting digital blocks: ADC interface, DPWM (digital PWM),  

• Collaborate closely with analog designers on loop compensation, sensor design, quantization effects, and delay budgeting. 

• Analyze and optimize for area, power, timing, and metastability in the digital controller across PVT corners. 

• Support silicon bring-up, debug, and controller on lab hardware.

What We’re Looking For 

• Strong mixed-signal background: Solid understanding of power circuits and digital control systems, digital filters etc. 

• Proven experience converting control algorithms into clean, synthesizable RTL (HDL Coder or hand-coded Verilog/SystemVerilog). 

• Deep knowledge of digital PID implementation challenges: quantization, sampling effects, computational delay, fixed-point arithmetic, and limit cycling. 

• Familiarity with high-frequency power converter control and digital PWM modulators (DPWM). 

• Experience with mixed-signal verification flows (analog-digital co-simulation). 

• Good understanding of analog effects impacting digital control: loop delay, sensor non-idealities, inductor non-linearities, PDN resonances. 

• Proficiency in digital design tools: Synopsys VCS, Verdi, Design Compiler, PrimeTime (or equivalent Cadence flow). 

• BSEE / MSEE or PhD with 8+ years of relevant experience in power management ICs or high-performance mixed-signal design.  

Nice to Have 

• Prior experience designing digital controllers for integrated voltage regulators (IVRs), point-of-load (PoL) converters, or high-current AI/HPC power delivery. 

• Experience with formal verification or assertion-based mixed-signal verification.
