Job summary

DensityAI is hiring a board-level physical design engineer in Mountain View to own the layout, stackup definition, and fabrication release for our accelerator silicon modules. You will manage high-speed routing, impedance, and large fine-pitch BGA escape while coordinating with SI, PI, packaging, and fab partners.

You will drive design-for-manufacturing and design-for-assembly with PCB vendors, support bring-up and debug, and contribute to advanced tooling to speed layout reviews and DRC checks.

Qualifications

• 8+ years PCB layout experience on server, networking, or accelerator-class systems with high layer counts.
• Experience with constraint-driven layout for high-speed, high-current boards.

Responsibilities

• Own board-level physical design for the systems our AI accelerators ship in stackup and impedance definition, placement, high-speed routing, and fabrication and assembly release packages
• Own high-current power delivery layout and large fine-pitch BGA escape for advanced accelerator packages
• Drive DFM/DFA with PCB fabrication and contract manufacturing partners, and support board bring-up and debug
• Use and develop AI assisted tool flows to accelerate layout, review, and design-rule checking

Job description

Own the board-level physical design that turns our accelerator silicon into systems. You'll take high-speed, high-power designs from placement through fabrication release — defining stackups, escaping large fine-pitch BGAs, routing multi-hundred-amp power delivery, and holding the constraint discipline that lets a channel close margin in the lab and not just in simulation. You'll work at the seam where the package meets the system, partnering with signal and power integrity, packaging, and hardware systems, and directly with the fabrication and assembly partners who build what you release. When a board comes back and something doesn't behave, you're one of the people who knows why.

What will you do

• Own board-level physical design for the systems our AI accelerators ship in stackup and impedance definition, placement, high-speed routing, and fabrication and assembly release packages
• Own high-current power delivery layout and large fine-pitch BGA escape for advanced accelerator packages
• Drive DFM/DFA with PCB fabrication and contract manufacturing partners, and support board bring-up and debug
• Use and develop AI assisted tool flows to accelerate layout, review, and design-rule checking

What we're looking for

• Exceptional abilities in constraint-driven layout of complex high-speed, high-current boards: controlled impedance and stackup definition, return-path and crosstalk management, length and skew matching, and via optimization
• 8+ years of PCB layout experience on server, networking, or accelerator-class systems at high layer counts
• Hands-on with industry-standard layout tools (Cadence Allegro, Siemens Xpedition, Altium, or equivalent) and release formats (Gerber, ODB++, IPC-2581)
• Demonstrated ability to work closely with signal-integrity, power-integrity, packaging, and hardware systems teams to implement and close complex constraint sets across package and board
• (Optional) 2.5D / 3D and multi-die package interfaces (CoWoS, EMIB, chiplets, HBM), rigid-flex or backplane design, CAD automation scripting, IPC CID / CID+, or overseas PCB fabrication and PCBA partner management

Full compensation packages are based on candidate experience and relevant certifications.

Compensation

Final offers depend on level, location, and skills relevant to the role. Additional compensation: equity grant per company guidelines; medical / dental / vision; 401(k); standard PTO.

DensityAI sponsors qualified candidates for H-1B, O-1, TN, E-3, and other employment-based visas, and we welcome applicants on F-1 OPT and STEM-OPT. Work authorization is required at start; we provide immigration support to secure or transfer status.

Export Controls

Aspects of this role may involve access to information subject to U.S. export controls (EAR/ITAR). We may discuss licensing or scope adjustments during the interview.

Voluntary Self-Identification of Disability

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

How do you know if you have a disability?

A disability is a condition that substantially limits one or more of your "major life activities." If you have or have ever had such a condition, you are a person with a disability. Disabilities include, but are not limited to:

• Alcohol or other substance use disorder (not currently using drugs illegally)
• Autoimmune disorder, for example, lupus, fibromyalgia, rheumatoid arthritis, HIV/AIDS
• Blind or low vision
• Cancer (past or present)
• Cardiovascular or heart disease
• Celiac disease
• Cerebral palsy
• Deaf or serious difficulty hearing
• Diabetes
• Disfigurement, for example, disfigurement caused by burns, wounds, accidents, or congenital disorders
• Epilepsy or other seizure disorder
• Gastrointestinal disorders, for example, Crohn's Disease, irritable bowel syndrome
• Intellectual or developmental disability
• Mental health conditions, for example, depression, bipolar disorder, anxiety disorder, schizophrenia, PTSD
• Missing limbs or partially missing limbs
• Mobility impairment, benefiting from the use of a wheelchair, scooter, walker, leg brace(s) and/or other supports
• Nervous system condition, for example, migraine headaches, Parkinson’s disease, multiple sclerosis (MS)
• Neurodivergence, for example, attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, dyslexia, dyspraxia, other learning disabilities
• Partial or complete paralysis (any cause)
• Pulmonary or respiratory conditions, for example, tuberculosis, asthma, emphysema
• Short stature (dwarfism)
• Traumatic brain injury
