The Product Engineer role is pivotal to Lightmatter's mission, sitting at the center of product delivery and operational excellence.
This position offers a unique opportunity for end-to-end ownership, where you will define the product engineering landscape from the ground up and drive the strategic direction for our hardware portfolio. You will collaborate with cross-functional teams (design, foundry, packaging, test, validation, reliability) to optimize manufacturing flows, improve yield and quality, and reduce costs.
The roles focus areas include:
- Optimizing Yield & Quality
- Implementing DFx principles
- Managing the product from initial silicon to high-volume manufacturing (HVM)
The core responsibilities are specifically centered on optimizing manufacturing flows, yield Improvement, and Test Point Optimization.
Strategic Ownership
Own the products success by managing yield and quality indicators from first silicon to high-volume manufacturing (HVM).
Manufacturing Excellence
Define manufacturing and test strategies, including DFT implementation, test hardware specs, and test program creation.
Yield & Cost Optimization
Drive continuous improvement in quality, yield, and cost by reducing test time, eliminating test sockets, closing test holes (DPM reduction), and increasing yield through root cause analysis with cross-functional teams (design, fab, packaging).
Hands on Leadership
Debug test, yield, and power/performance issues.
Guiding Light
Lead multi-disciplinary teams (Design, Foundry, Packaging, Supply Chain, etc.) to resolve product issues and continuously improve team tools and methods.
Qualifications
- Master's in Computer Science, Electrical Engineering, Physics, Material Science or a related field
- A minimum of 5+ years experience in semiconductor industry as a product engineer, with a cumulative of 12 years of relative industry experience
- Experience developing DFT strategy
- Experience developing test plans
- Familiarity with advanced packaging flows
- Familiarity with ATE Test area equipment and methodology
- Experience partnering with OSATs to develop manufacturing test flows for CMOS or Optical transceiver products
- Excellent communication skills with ability to present complex technical information clearly and concisely
- Demonstrated ability to influence senior company leadership and partner with vendors and customers
- Familiarity with statistical analysis & data acquisition tools such as JMP, Snowflake
Preferred Qualifications
- Experience partnering with a OSAT to develop manufacturing test flows for Co-Packaged Optics technology
- Programming or scripting: Python, C, Java, Ruby, SQL, or shell scripting
