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 NowThe Market Window
The semiconductor industry is going through its biggest architectural shift in 40 years:
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 WorkNo 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 BangaloreMove 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.
READY TO JOIN?
What You’ll Do
Architect , and implement
digital PID / cascade control loops (voltage-mode, current-mode, or hybrid) for high-frequency multi-phase IVRs operating at 10–100 MHz. Design
production-quality RTL (Verilog / SystemVerilog) for control loops, state-machines and related designsDesign and implement supporting digital blocks and integrate 3rd party micro-controller etc IPs. 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 tuning on lab hardware.
What We’re Looking For
BSEE / MSEE or PhD with
8+ years of relevant experience in power management ICs or high-performance mixed-signal design.
Strong RTL background: Solid understanding of micro-architecture and Logic design as well as
digital control systems etc.
Proven experience designing and / or converting MATLAB/Simulink control algorithms into
clean, synthesizable RTL 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 for synthesis, simulation etc.
Good to Have
Prior experience designing digital controllers for
integrated voltage regulators (IVRs), point-of-load (PoL) converters, or high-current AI/HPC power delivery. Knowledge of advanced topologies: 3-level buck, multi-level converters, hybrid switched-capacitor + inductive converters. Experience with formal verification or assertion-based mixed-signal verification.
