About Mixx Technologies

Mixx Technologies is building next-generation optical interconnect solutions that enable true system-level integration for hyperscale data centers. We combine expertise in silicon photonics, packaging, fiber connectivity, and system integration to deliver products that set recent standards for performance, density, and scalability to drive the next generation of artificial intelligence.

Position Overview

We are seeking a highly skilled Senior ATE Test Engineer to join our team. This role is pivotal in bridging the gap between sub-micron optical alignment and high-speed digital silicon validation. You will be responsible for the end-to-end validation EIC (CMOS Chips) and high-volume production on industry-leading ATE platforms.

Your Core Impact:

• EIC Validation: Own the post-silicon validation lifecycle for cutting-edge Electronic IC to work with Photonics ICs.

• Hardware Innovation: Collaborate with PCB layout teams to develop schematics and design guidelines for probe cards and final test load boards.

• Program & Automate:



Code robust ATE test programs from scratch using C#, C++, Python, or VB.

• Silicon Bring-up: Drive debugging and characterization efforts alongside Design and DFT teams on advanced tester platforms.

• Mass Production Release: Take full ownership from initial datasheet analysis to releasing final production-quality wafer test programs.

What We Are Looking For:

• Experience: 8 to 10 years of deep expertise in the Semiconductor industry.

• Domain Focus: Proven exposure to Mixed-Signal, Digital, or High-Speed RF domains and Open to learn & develop Test Solution for Silicon Photonics ICs

• ATE Platform Mastery: Hands-on experience with tester platforms such as Teradyne (Microflex, UFlex, UFlex+) or Advantest (V93K – Smart Scale. Exa Scale). HVM transfer in both Wafer sort and Final/Package test is advantage.

• Leadership & Communication: Ability to act as the technical interface for Internal teams on test requiremen
