Senior Hardware Systems Design Engineer

Mythic is building next-generation AI hardware platforms that require tight integration between silicon, package, PCB, system architecture, and manufacturing execution. We are looking for a hands-on Senior Hardware Systems Design Engineer to own the design and implementation of complex reference boards, customer-facing hardware platforms, and system-level board solutions.

This is a build role for an experienced hardware engineer who can take evolving silicon capabilities, incomplete requirements, mechanical and manufacturing constraints, and high-speed interface requirements, then turn them into robust, manufacturable PCB designs.

The ideal candidate has deep experience designing complex boards from concept through schematic, PCB layout guidance, signal integrity review, fabrication documentation, assembly support, bring-up, debug, and customer or manufacturing handoff. You should be comfortable working across high-speed digital, power delivery, RF/digital partitioning, clocking, board stack-up, connectors, vendor management, and production readiness.

You will play a critical role in transforming Mythic’s silicon into usable hardware platforms for internal development, customer evaluation, partner integration, and production deployment.

• Own the design and development of reference boards, evaluation platforms, and system-level hardware platforms for Mythic silicon.
• Translate silicon capabilities, package constraints, and product requirements into practical, high-quality board-level designs.
• Drive schematic design and work closely with internal or external PCB layout resources to deliver complex, manufacturable PCBs.
• Own key board-level subsystems including power delivery, high-speed interfaces, clocking, connectors, control interfaces, and board management circuitry.
• Design and review high-speed digital interfaces such as PCIe, Ethernet, SerDes, SPI, I2C, GPIO, and related board-level interconnects.
• Apply signal integrity and power integrity best practices to high-speed PCB designs, including stack-up planning, impedance control, routing constraints, retimers/redrivers, and layout verification.
• Incorporate package-level, mechanical, thermal, and manufacturing constraints into board architecture and PCB implementation.
• Work with PCB fabrication, assembly, test, and manufacturing partners to ensure smooth prototype builds and production readiness.
• Generate and release complete design documentation including schematics, fabrication notes, assembly notes, BOMs, layout constraints, and production support material.
• Support board bring-up, debug, validation, and system integration in collaboration with silicon, firmware, software, test, product, and manufacturing teams.
• Drive design-for-manufacturability (DFM), design-for-test (DFT), and design-for-reliability (DFR) improvements across prototype and production builds.
• Identify and resolve system-level issues involving board layout, power, clocking, signal integrity, RF/digital interaction, connectors, and manufacturing variation.
• Work closely with integration, product, test, and packaging teams to ensure successful system deployment

• Significant experience in board-level hardware design, PCB design, or systems hardware engineering.
• Proven track record designing and bringing up complex, high-speed PCBs.
• Strong background in high-speed digital design, SerDes interfaces, controlled impedance routing, and board stack-up planning.
• Experience with PCIe, Ethernet, SFP/SFP+, retimers, redrivers, FPGAs, embedded control interfaces, or similar high-speed platforms.
• Strong understanding of power delivery, power rail planning, filtering, sequencing, and board-level power integrity.
• Experience with schematic capture, PCB layout tools, and layout review using tools such as Altium, Cadence, Mentor PADS, HyperLynx, or similar.
• Ability to guide PCB layout vendors or internal layout designers through placement, routing, constraints, documentation, and design reviews.
• Experience releasing PCB fabrication packages, assembly documentation, BOMs, and manufacturing support files.
• Hands-on experience supporting PCB bring-up, debug, system test, and early production builds.
• Ability to operate in fast-moving environments where requirements may evolve and engineering judgment is required.
• Strong ownership mindset, attention to detail, and ability to drive designs from concept through working hardware.

• Minimum Bachelor’s degree in any engineering field, with 15+ years of hands-on experience designing, implementing, bringing up, and releasing complex PCB and hardware systems.
• Experience with AI hardware, accelerator platforms, high-performance compute, networking platforms, or advanced semiconductor evaluation boards.
• Experience designing boards that include high-speed digital, RF, analog, and power circuitry on the same platform.
• Familiarity with package-to-board interactions, advanced packages, multi-die systems, or chiplet-based systems.
• Experience working with OSATs, PCB fabricators, assembly houses, contract manufacturers, and external design/layout vendors.
• Experience with thermal, mechanical, enclosure, and connector constraints in compact or production hardware systems.
• Experience supporting hardware through customer evaluation, field deployment, or manufacturing transition.
• Background with FPGA-based platforms, PCIe root complex/endpoint systems, 10G Ethernet, RF modules, or embedded system boards.

• Mythic reference boards and hardware platforms are robust, reliable, and require minimal re-spins.
• Board designs successfully integrate silicon, package, power, clocking, high-speed interfaces, and mechanical constraints.
• Hardware platforms are easy to bring up, stable in system integration, and ready for customer or partner use.
• PCB layouts meet signal integrity, power integrity, manufacturability, and reliability expectations.
• Prototype builds transition smoothly into manufacturable, documented, and supportable hardware.
• External vendors receive clear guidance, complete documentation, and timely technical decisions.
• Integration, product, test, firmware, software, and manufacturing teams have the hardware support they need to move quickly.

At Mythic, hardware design is how we turn advanced silicon into real systems that customers and partners can evaluate, integrate, and deploy.

This role is central to building the boards and platforms that showcase the full value of Mythic’s technology. You will make critical design decisions, work across silicon and systems, and directly influence the quality, usability, and manufacturability of Mythic hardware.

If you are a hands-on senior hardware engineer who enjoys building complex boards, solving system-level problems, working with vendors, and driving designs all the way from concept to functioning hardware, we should talk.

• Work on ambitious AI hardware with real system complexity.
• Own critical board and systems design at a company where your work directly impacts product delivery.
• Join a highly collaborative team solving difficult engineering problems across silicon, package, board, and system design.
• Move fast, make decisions, and build from first principles.
• Have outsized impact in a role with real scope and visibility.
