Role Overview

We are seeking a SoC Architect to define and drive the architecture of next-generation XPUs for AI Infrastructure. This role involves end-to-end ownership of system and SoC architecture, from concept to silicon, with a strong emphasis on scalability, performance, interconnects, and system-level optimization.

Key Responsibilities

Define system architecture for complex SoCs, including compute, interconnect, memory, and IO subsystems
Drive architecture for scalable and modular designs, including chiplet-based systems (UCIe)
Architect high-performance data movement across:

Compute engines (ARM/RISC-V/ML/MAC)

Memory subsystems (DDR/LPDDR/HBM)

IO interfaces (PCIe/UCIe/CXL/UALink/ESUN)
Collaborate with design and DV teams to ensure architectural feasibility and efficient implementation
Develop performance models and simulations to validate architecture choices
Drive trade-offs across: Performance, Power, Area and Cost
Define system-level verification and validation strategies
Work closely with customers and software teams to align architecture with real-world workloads
Influence long-term roadmap and technology direction

Required Qualifications

Bachelor's/Master's/PhD in Electrical Engineering, Computer Engineering, or related field
18+ years of experience in SoC or system architecture
Proven track record of architecting complex SoCs for AI, HPC, or Networking
Deep understanding of:

System-level design and trade-offs

High-speed IO protocols (UCIe, PCIe, Ethernet)

Data movement and interconnect design

Experience with performance modeling and architectural simulation
Strong cross-functional collaboration skills

Preferred Qualifications

Experience with memory architectures (DDR, HBM, cache hierarchies)
Familiarity with chiplet architectures and advanced packaging (2.5D/3D)
Knowledge of coherency protocols (CXL, CHI.)
Experience with power/performance optimization at system level
Exposure to software-hardware co-design

Key Attributes

Strong system-level thinking and architectural vision
Ability to balance innovation with practical execution
High ownership and accountability
Strong communication and leadership skills

Success Metrics

Scalable and efficient SoC architectures across multiple generations
Achievement of performance, power, and cost targets
Strong alignment between architecture and silicon outcomes
Reduced architectural rework through early validation

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

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 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

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.
