Senior / Principal PIC Test Engineer

Role Overview

We are seeking an experienced PIC Test Engineer with deep expertise in both wafer-level and die-level optical and electrical test for Photonic Integrated Circuits (PICs).

This role will own the test strategy and execution across the full product lifecycle—from early silicon bring-up through high-volume manufacturing (HVM).

The ideal candidate is a recognized technical authority in test architecture, PIC Design-for-Test (DFT), yield learning, and factory scalability, with proven leadership in driving robust test solutions across multiple technology nodes and product families.

Key Responsibilities-

Wafer-Level Test Strategy & Architecture

Define and own the wafer-level PIC test roadmap across multiple product lines and technology platforms.

Architect scalable, high-throughput optical + electrical wafer probe solutions, balancing alignment accuracy, probe stability, and test time.

Establish release criteria, guard-banding strategy, and wafer test coverage models aligned with product requirements.

Die-Level Testing

Define and own tests not carried out at wafer level. Examples include Optical Vector Analysis (OVA) testing, and polariazation-resolved testing.

First Silicon Bring-Up & Test Content Development

Lead first-silicon bring-up efforts, including test content definition, limit setting, and characterization flows.

Drive rapid yield-learning loops in partnership with design, process integration, and fabrication teams.

Enable fast debug and iteration during early node transitions and new platform ramps.

DFT & PDK Collaboration

Influence PIC Design-for-Test features and PDK structures to improve wafer-level Scalability, Including

• On-chip monitors
• Loopback paths
• Test waveguides
• Calibration structures

Partner with design teams to embed manufacturable test hooks early in the development cycle.

Yield Ownership & Data-Driven Analysis

Own wafer-level yield, parametric distributions, and systematic defect learning.

Perform advanced spatial analytics using wafer maps and statistical methods to separate random vs systematic process issues.

Lead root-cause investigations related to lithography bias and process drift.

Manufacturing Readiness & Factory Scale-Up

Establish golden wafer / golden die methodologies for production stability and tool correlation.

Partner with foundries and OSATs to qualify wafer-level optical probe infrastructure.

Drive successful transfer of test flows into volume manufacturing environments with strong cross-tool correlation.

Technical Leadership & Team Development

Serve as the technical escalation point during yield crises and manufacturing transitions.

Mentor and develop junior engineers, setting engineering standards and best practices across wafer-level test programs.

Multiply organizational impact through scalable infrastructure, DFT influence, and test standardization.

Qualifications

Required

10+ years of experience in PIC test engineering, wafer-level probing, or photonics manufacturing test.

Proven ownership of wafer-level optical/electrical test strategy from R&D through HVM.

Expertise In

• Wafer-level optical probing
• Die-level test development. For example: characterization of polarization splitter-rotators and characterization of component backreflection.

• Probe card qualification
• Yield learning and spatial analysis
• Test time optimization
• Foundry engagement and factory transfer

Preferred

Experience with high-speed optical and electrical testing of photonic integrated circuits or optical transceivers.

Experience specifically with silicon photonics PICs, testing over a broad wavelength range.

Experience influencing PIC DFT and collaborating closely with PDK development teams.

Strong background in high-volume semiconductor or photonics manufacturing ecosystems.

Demonstrated leadership in scaling test infrastructure across multiple nodes and product families.
