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.

The 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.

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

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.

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.

Build the platform that brings silicon to life before tapeout.

TYLsemi is developing a purpose-built connectivity chiplet for HPC / rack-scale AI systems. We are seeking a Principal Engineer Emulation Lead to create scalable pre-silicon environments that enable firmware, software, and system validation months before first silicon arrives. You'll build production-grade platforms that boot real software, run meaningful workloads, expose system bottlenecks, and accelerate product readiness across the organization.

Architect and deploy full-chip, multi-die, and subsystem emulation environments using Palladium,
ZeBu, Veloce
, or similar platforms.

Enable pre-silicon bring-up of boot ROM, firmware, drivers, operating systems, and application workloads.

Develop scalable emulation methodologies and reusable infrastructure, Drive system-level validation, performance analysis, and root-cause debug across RTL, firmware, software, and verification.

Build automation, CI/CD workflows, regressions, and release processes that scale across engineering teams.

Partner with architecture, design, verification, firmware, DFT, and post-silicon teams to reduce product risk before tapeout.

Influence methodology, observability, debugability, and overall silicon readiness.

Lead complex debug spanning RTL, firmware, software, and hardware platforms.
