Mixed-Signal Verification Engineer – Power Management ICs

TYLsemi; Bengaluru; Hybrid; INR 3,000,000 - 5,200,000; Full time

Job summary

TYLsemi, Inc. is seeking an experienced mixed-signal verification engineer in Bengaluru to lead verification plans for high-current IVR designs. You will build analog behavioral models and perform analog-digital co-simulation using Cadence and Synopsys tools.

You will develop testbenches, run multi-parameter regressions across PVT corners, and collaborate with analog/digital teams to improve coverage and turnaround. A strong background in power converters and SystemVerilog/UVM is required.

Qualifications

• 8+ years of hands-on experience in mixed-signal verification of power management ICs or analog/mixed-signal SoCs.
• Strong proficiency in mixed-signal simulation flows.
• Real Number Modeling (RNM) and Verilog-A behavioral modeling.
• Analog-digital co-simulation (AMS, VCS + Spectre, Xcelium).
• Solid understanding of power converter topologies (buck, multi-phase, 3-level buck, switched-capacitor converters).
• Good knowledge of digital control concepts for power converters (PID controllers, DPWM, digital feedback loops).
• Experience with MATLAB/Simulink for system-level modeling and testbench reference generation.
• Proficiency in SystemVerilog and UVM for digital/mixed-signal testbenches.
• Familiarity with Cadence Virtuoso, Spectre, or Synopsys CustomSim for analog simulation.
• Understanding of analog non-idealities (quantization effects, loop delay, sensor offsets, PDN resonances, inductor non-linearities).
• BSEE / MSEE with 8+ years relevant experience.

Responsibilities

• Develop and execute mixed-signal verification plans for high-current IVR designs.
• Build and maintain analog behavioral models (Verilog-A / SystemVerilog real-number modeling) for power stages, integrated inductors, PDN, and analog blocks.
• Perform analog-digital co-simulation using industry-standard tools (Cadence Xcelium + Spectre, Synopsys VCS + FineSim / CustomSim, or AMS Designer).
• Create testbenches for key performance metrics: transient response (load steps), loop stability, efficiency, ripple, over-current / over-voltage protection, and startup/shutdown sequences.
• Run regressions across PVT corners, Monte-Carlo analysis, and corner-case scenarios.
• Debug mixed-signal issues at both transistor-level and behavioral level.
• Collaborate closely with analog designers, digital designers, and system engineers to close verification coverage.
• Develop automated verification scripts and improve verification methodology for faster turnaround.
• Support post-silicon validation by correlating simulation results with lab measurements.

About TYLsemi, Inc.

The Opportunity

The AI infrastructure market is exploding. Every hyperscaler, every cloud provider, every AI company is building custom silicon. But they all face the same problem: how do you connect hundreds of chips, deliver clean power at scale, and move terabits of data without melting the package? That's what we solve. TYLsemi builds the chiplet infrastructure IP — the IO, power delivery, and interconnect building blocks — that makes AI/HPC systems actually work at scale.

This isn't a nice-to-have. It's the critical path.

Why Now

The Market Window

• Moore's Law is dead. 2nm and beyond delivers marginal performance gains. The future is chiplets, not monolithic dies.
• Custom silicon is now mainstream. Google, Microsoft, Amazon, Meta, OpenAI — they're all designing their own ASICs. The $50B custom silicon market is growing 30% annually.
• IO and power are the bottleneck. Solve hard problems and provide something which is a category in itself.
• Translation: We're entering the market at exactly the moment when every major AI/HPC player needs what we're building, and their alternatives are disappearing.

Culture & Team: How We Work

No Politics, No Bureaucracy

• If you have an idea, we test it. If it works, we ship it.
• No endless meetings, no PowerPoint presentations to convince middle management.

Remote-Friendly, Global Team

• US team: Bay Area preferred, but we hire the best people regardless of location
• India team: Building a world-class design center in Bangalore

Move Fast, Ship Real Products

We're not a research project. We have paying customers, committed capital, and aggressive timelines. This is a company, not a lifestyle business. We're building to win.

What We Value

• Ownership mindset. You're not here to execute someone else's roadmap. You're here to define it.
• Bias for action. We move fast. Analysis paralysis doesn't fly here.
• Deep technical expertise. This is hard engineering. We need people who've shipped real silicon and debugged real hardware.
• Low ego, high standards. We don't care about titles or politics. We care about results.

The Ask

If you're reading this, you're probably comfortable. You have a good job at a stable company with all the benefits.

We're asking you to walk away from that and bet on us.

Here's Why You Should

• The market is real. AI infrastructure spending is $200B+ annually and growing 40% YoY. Every hyperscaler needs what we're building.
• The team has done this before. We've built and exited semiconductor companies at scale. This isn't our first rodeo.
• The traction is de-risked. We have LOIs, strategic investors, and a clear path to revenue.
• The work is consequential. You're not optimizing someone's ad click-through rate. You're building the silicon infrastructure that powers AI.

This is the bet.

Join us and build something that matters.

Or stay comfortable. No judgment.

But if you're the kind of person who wants to take the shot, we'd love to talk.
