Title:

Co-Founder / Chief Technology Officer – Advanced Packaging and Test (Outsourced Semiconductor Assembly and Test for Artificial Intelligence)

Location note:

Primary hub:

Santa Clara, California (Hybrid)

Also very open to candidates currently in the

Folsom / Sacramento area

and the

Phoenix / Chandler / Tempe, Arizona region .

I am building

NextZen Forge

– a new kind of advanced packaging and test platform (Outsourced Semiconductor Assembly and Test, also known as OSAT) focused on the bottleneck of the artificial intelligence hardware world:

Seventy‑two‑hour Failure Analysis (FA)

for

Graphics Processing Unit (GPU)

and

High Bandwidth Memory (HBM)

modules

Time‑boxed New Product Introduction (NPI) pilot attach

windows

Auditable, data‑transparent quality

that hyperscalers and artificial intelligence chip startups actually trust

We will start with a

Failure Analysis and pilot New Product Introduction lab in Folsom / Sacramento , then scale attach and test capacity in

Arizona , and later add a

support hub in another location (if needed)

I am looking for a

Co-Founder / Chief Technology Officer

with deep experience in advanced packaging who wants to help architect this from day zero.

You will own

Designing and qualifying attach, underfill, reflow, clean, inspection, and reliability flows for Graphics Processing Unit / High Bandwidth Memory, flip‑chip ball grid array, and two‑and‑a‑half‑dimensional / three‑dimensional assemblies

New Product Introduction through to ramp: designing Design of Experiments, running first‑article and qualification lots, driving Statistical Process Control, and owning yield and Overall Equipment Effectiveness targets

Tool and facility decisions for the Folsom / Sacramento Failure Analysis lab and the first Arizona attach and test line (Mechanical, Electrical, and Plumbing loads, layouts, and vendor selection)

Technical customer interface with artificial intelligence chip companies, hyperscalers, memory vendors, and original equipment manufacturers

Building and mentoring the first engineering team (New Product Introduction, reliability, Failure Analysis technicians, quality)

You might be a fit if

You have

10–20+ years

in advanced semiconductor packaging, module engineering, or Failure Analysis at an Outsourced Semiconductor Assembly and Test provider or device maker

You have personally taken High Bandwidth Memory, interposer, chiplet, or flip‑chip packages from New Product Introduction into volume production

You are comfortable specifying and qualifying C‑Mode Scanning Acoustic Microscopy, Automated X‑ray Inspection, underfill and attach tools, and you know how to read yield and defect paretos in your sleep

You want to be a

true co‑founder , not just an employee

Compensation (founder‑level)

Equity only at the beginning:

Based on experience and commitment

After the first external funding round: salary in the range of

240,000–300,000 United States Dollars , plus bonus and benefits

Hybrid between

Santa Clara

and

Folsom / Sacramento , with some travel to

Arizona

as the attach and test line ramps

About me

I am

Santanu , Founder and Chief Executive Officer of

NextZen.ai

and

NextZen Security LLC . My background is in cybersecurity, trust, and systems. I am combining that with your deep packaging experience to build an advanced packaging platform designed for

speed, transparency, and security

from day one.
