Key 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).
- Verify digital control loops
- 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.
Required Qualifications
- 5+ 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.
Preferred Qualifications
- Experience verifying high-frequency IVRs, PoL regulators, or high-current power delivery systems.
- Experience with SIMPLIS, PLECS, or Simulink for system-level power electronics validation.
- Familiarity with digital PID controller verification and fixed-point arithmetic effects.
- Exposure to advanced packaging and on-die inductor modeling.
- Scripting skills in Python, Perl, or Tcl for automation.
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?
Thats 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 isnt a nice-to-have. Its the critical path.
Why Now
The Market Window
The semiconductor industry is going through its biggest architectural shift in 40 years:
- Moores 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 — theyre 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: Were entering the market at exactly the moment when every major AI/HPC player needs what were building, and their alternatives are disappearing.
Culture & Team: How We Work
No Politics, No Bureaucracy
There are no layers, no approval chains, no corporate theater.
- 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
Were not a research project. We have paying customers, committed capital, and aggressive timelines.
This is a company, not a lifestyle business. Were building to win.
What We Value
- Ownership mindset. Youre not here to execute someone elses roadmap. Youre here to define it.
- Bias for action. We move fast. Analysis paralysis doesnt fly here.
- Deep technical expertise. This is hard engineering. We need people whove shipped real silicon and debugged real hardware.
- Low ego, high standards. We dont care about titles or politics. We care about results.
The Ask
If youre reading this, youre probably comfortable. You have a good job at a stable company with all the benefits.
Were asking you to walk away from that and bet on us.
Heres Why You Should
- The market is real. AI infrastructure spending is $200B+ annually and growing 40% YoY. Every hyperscaler needs what were building.
- The team has done this before. Weve built and exited semiconductor companies at scale. This isnt our first rodeo.
- The traction is de-risked. We have LOIs, strategic investors, and a clear path to revenue.
- The work is consequential. Youre not optimizing someones ad click-through rate. Youre 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 youre the kind of person who wants to take the shot, wed love to talk.
