About the team

The Process Team sits at the heart of our in-house device development, driving the design of each new generation of tools. This is unlike any role at a traditional foundry-we simultaneously develop recipes, apply novel materials, test and characterize our chips, and troubleshoot tools.

About the role

As a Semiconductor Test Development Engineer at Atomic Semi, you'll play a critical role in bridging process development, and electrical test. Your work will focus on characterizing semiconductor devices, designing and automating test infrastructure, and extracting key electrical parameters to inform process improvements. This is a hands-on, high-ownership role that requires both deep technical understanding and strong collaboration with process, test, and design engineers.

We're looking for someone who's excited to work across disciplines developing probe cards, designing test structures, running electrical characterization, and building automation infrastructure. A background in device physics and experience with CMOS modeling (e.g., BSIM) will be valuable, especially for parameter extraction and feedback into process development.

You'll have the opportunity to work across the full testing stack from test structure design to silicon fabrication and data analysis. Your contributions will help shape how we validate and improve our CMOS processes in a fast-paced, startup environment.

Responsibilities

• Collaborate with process and electrical engineers to design probe cards and test structures
• Design and fabricate CMOS test chips for characterization and calibration
• Develop and implement test plans to extract key device parameters (e.g., threshold voltage, mobility, leakage)
• Deploy parameter extraction tools and methods (e.g., BSIM models) to characterize devices and model performance
• Analyze test data to provide feedback to process engineers, helping improve materials and process flows
• Develop and maintain test automation infrastructure for streamlined electrical characterization
• Document test results and characterization findings clearly and rigorously

Required Experience

• BS, MS, or PhD in Electrical Engineering, Applied Physics, or a related field
• Strong understanding of CMOS device physics and electrical characterization
• Experience with probe station operation
• Familiarity with parameter extraction techniques and device modeling (e.g., BSIM)
• Experience with lab instrumentation and test automation
• Hands-on experience with semiconductor device fabrication and test structures

Nice-to-have

• Experience with process development kits (PDKs) and test chip layout
• Experience with cleanroom fabrication and full CMOS process flow
• Experience conducting reliability testing and analysis
