About the Job

Requirements

A degree in Chemical Engineering, Materials Science, Electrical Engineering, Chemistry, or a related technical field, or equivalent experience.
At least 5 years of hands-on plating process engineering experience in a semiconductor fab, especially in an advanced logic, memory, or foundry environment.
Deep experience with electrochemical deposition tool qualification, copper plating process development, and process of record establishment at advanced nodes.
Proficiency with plating metrology tools for film thickness measurement, defect inspection, resistivity measurement, and electrochemical analysis.
Strong Design of Experiments skills and statistical analysis capability.
Ability to work closely and proactively across lithography, etch, thin films, integration, and equipment engineering teams.

Responsibilities

Develop and qualify electrochemical deposition processes for copper damascene interconnect and through-silicon via fill across all metal levels, including metrology monitoring and defect inspection for bath health and process control.
Optimize plating bath chemistry, current density profiles, additive formulations, and annealing conditions for void-free, low-stress copper fill at aggressive aspect ratios.
Develop and qualify electroless plating processes for capping layers and barrier-free interconnect schemes, including cobalt and ruthenium, as applicable to advanced node requirements.
Qualify plating tools from installation through production readiness, including bath conditioning, anode management, and process window qualification.
Analyze processes using a first-principles, physics-based approach to understand and manipulate mechanisms rather than relying only on recipes.
Lead root-cause analysis, establish inline metrology and control strategies, and drive systematic yield improvement.
Support 24/7 manufacturing operations through rotations, on-call availability, and rapid response to critical production issues.
Drive next-generation plating chemistry and process development.
Develop and own electrochemical deposition processes across edge-inference processors, space-hardened satellite chips, and high-bandwidth memory.
Control void-free fill, thickness uniformity, and grain structure while managing bath chemistry, current distribution, and seed layer interactions across extreme aspect ratios and feature sizes.

Job Description

We are building Terafab, a vertically integrated semiconductor factory at an unprecedented scale. The facility houses logic, memory, packaging, test, and lithography mask production under one roof, optimized for rapid iteration and maximum compute density per square foot. Process engineering is where Terafab technology gets built, atom by atom, and plating fills the structures that connect the chip. You will develop and own electrochemical deposition processes across three distinct chip families: edge-inference processors, space-hardened chips for orbital satellites, and high-bandwidth memory. You'll control void-free fill, thickness uniformity, and grain structure while managing bath chemistry, current distribution, and seed layer interactions across extreme aspect ratios and feature sizes. You should have deep expertise in electrochemical deposition but be ready to work across core process domains such as seed layer deposition, metrology, and barrier integration evolves. This is a highly hands-on role in one of the most ambitious fab programs in the world.

Job Responsibilities

Develop and qualify electrochemical deposition (ECD) processes for copper damascene interconnect and through-silicon via (TSV) fill across all metal levels including metrology monitoring and defect inspection for bath health and process control

Optimize plating bath chemistry, current density profiles, additive formulations, and annealing conditions for void-free, low-stress copper fill at aggressive aspect ratios

Develop and qualify electroless plating processes for capping layers and barrier-free interconnect schemes (Co, Ru) as applicable to advanced node requirements

Qualify plating tools from installation through production readiness, including bath conditioning, anode management, and process window qualification

Analyze processes from a first-principles, physics-based approach to understand and manipulate mechanisms, not just recipes

Lead root cause analysis, establish inline metrology and control strategies, and drive systematic yield improvement

Support 24/7 manufacturing operations through rotations, on-call availability, and rapid response to critical production issues

Drive next-generation plating chemistry and process development

Job Requirements

Degree in Chemical Engineering, Materials Science, Electrical Engineering, Chemistry, or related technical field, or equivalent experience

5+ years of hands-on plating process engineering experience in a semiconductor fab, especially advanced logic, memory, or foundry environment

Deep experience with ECD tool qualification, copper plating process development, and process of record (POR) establishment at advanced nodes

Proficiency with plating metrology tools: film thickness measurement, defect inspection, resistivity measurement, and electrochemical analysis

Strong Design of Experiments skills and statistical analysis capability

Ability to work closely and proactively across lithography, etch, thin films, integration, and equipment engineering teams

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
