Test Engineering Intern Tech III - US-CA-Santa Clara-Bldg 2-Keysi, United States
$37 - $40 USD yearly
Originally posted 12 October 2026 by the employer.
Work at the intersection of software development, metrology, and advanced optical manufacturing.
About the role
This role offers a high-impact opportunity to work at the intersection of software development, metrology, and advanced optical manufacturing within Keysight’s Semiconductor Infrastructure Solutions (SIS) organization, which designs and manufactures laser interferometry systems, precision optical components, monolithic optics (CMOs), and advanced electronic test & measurement solutions.
What you'll do
- Develop, deploy, and sustain production‑critical systems supporting manufacturing operations, yield improvement, and inspection throughput.
- Design, develop, and support software for metrology systems and inspection automation across the factory.
- Perform full‑stack application development, hardware and instrument integration, scripting and automation for measurement tools, and construction of data pipelines.
- Interface with custom instrumentation, cameras, microcontrollers, CNC equipment, and legacy systems, often against hardware still under design.
- Modernize engineering workflows, replacing manual and highly technical engineering tools with intuitive, user‑friendly environments.
- Ensure documentation, code quality, and long‑term maintainability for sustained solutions.
What you'll need
- Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, or a closely related field.
- Strong foundation in software engineering principles, including data structures, algorithms, version control, and debugging.
- Demonstrated proficiency in multiple high‑level programming language (e.g., Python, C#, JavaScript) for engineering tools and automation.
- Demonstrated proficiency in at least one low-level capable language (e.g. Rust, C++) for engineering tools and automation.
- Experience developing maintainable, production‑quality code through coursework, internships, co‑ops, or project work.
- Basic understanding of software interaction with hardware or external systems (e.g., instrumentation APIs, IPC, device I/O, or sensor data).
- Clear written and verbal communication skills, including the ability to produce technical documentation.
- Careful, structured working methods suitable for production and manufacturing environments.
Nice to have
- Pursuing Master's Degree in Computer Science, Software Engineering, Computer Engineering, or a closely related field.
- Prior internship, co‑op, or project experience supporting manufacturing, metrology, instrumentation, robotics, or industrial automation.
- Experience with full‑stack or application development.
- Familiarity with instrument interface programming with NI Lab-View or Keysight Vee.
- Familiarity with data acquisition systems, measurement equipment, or scientific/engineering data workflows.
- Exposure to image processing or computer vision concepts.
- Experience working with legacy codebases or refactoring partially documented software.
- Experience interfacing software with CNC machines, lasers, cameras, microcontrollers, or similar hardware.
