SoC RTL Design Engineer Full Time

• Specify and own the reset sequencing architecture. Own the secure boot and fuse micro architecture and design.
• Coordinate with the subsystem leads on reference clock distribution, clock-domain crossing points at subsystem interfaces.
• Collaborate with the firmware team to define the hardware/software interface: interrupt controller, timer, UART/JTAG debug port, and any DMA or mailbox channels
• Own the clock-gating implementation strategy: coarse-grain vs. fine-grain gating, ICG cell selection, and sign-off methodology for dynamic power reduction.
• Define the chip-level power-domain plan: which blocks share supplies, where level-shifters and isolation cells are required, and how power states map to the PCIe and UCIe link power management protocols.
• Own the on-chip power management logic: power-state machine, supply sequencing, voltage regulator integration, and the firmware interface for runtime power control.
• Drive power intent (UPF/CPF) authoring and sign-off, coordinating with physical design team on power-domain floorplan, always-on routing, and isolation verification.
• Own the embedded management processor subsystem: processor integration, on-chip SRAM and ROM sizing, boot sequence, fuse and OTP interface, and the firmware execution environment.
• Define the management register map: the address space through which firmware configures operating modes, reads telemetry, controls power states, and manages DFT operations.
• Specify thermal monitoring integration: on-die temperature sensor placement, readout path to the management processor, and thermal throttling hooks.

Required Qualifications

• BS/MS in Electrical Engineering, Computer Engineering, or equivalent. 8+ years of digital IC design, with at least 3 years owning chip infrastructure — clocking, power management, reset or DFT — at block-lead or subsystem-owner level.
• Familiarity with embedded microcontroller integration: memory maps, boot ROM, interrupt controllers, and firmware bring-up at the hardware level.
• Experience with reset-domain architecture and reset synchronizer design in multi-power-domain chips.
• Strong SystemVerilog skills for infrastructure RTL: clock-gating cells, power FSMs, scan-enable muxing, and BIST controllers.

Preferred Qualifications

• Background integrating a RISC-V or ARM Cortex-M class processor as a management/configuration engine in a non-CPU chiplet.
• Exposure to hardware security: secure boot, anti-tamper fuse programming, or related infrastructure.

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.
