Senior Product Development Engineer

Scope:

Drive end-to-end development and integration of MicroLED AR display modules, connecting the MicroLED display chip, CMOS backplane, package, driver electronics, and optical engine. Translate product requirements into module-level specifications and validation plans; coordinate internal teams and external partners; troubleshoot system-level issues; and deliver characterized prototypes for customer evaluation and product commercialization.

Key Responsibilities:

• Lead end-to-end integration of MicroLED display chips, CMOS backplanes, package structures, driver boards, and optical engine components.
• Translate customer and application needs into module-level requirements, interface definitions, development plans, and measurable performance targets.
• Coordinate display, CMOS, packaging, hardware, firmware, optics, test, and manufacturing contributors to resolve cross-subsystem issues.
• Bring up and debug display modules, including power delivery, electrical interfaces, timing, grayscale control, pixel behavior, image artifacts, and communication interfaces.
• Work with packaging teams and external suppliers on die/backplane integration, bonding and interconnects, assembly builds, alignment, and packaging-related failure analysis.
• Integrate MicroLED modules with optical components such as collimation optics, micro-optics, and AR waveguides, as applicable to the product.
• Plan and execute electrical and optical characterization covering luminance, wavelength, color, uniformity, grayscale response, optical efficiency, and power consumption.
• Analyze engineering data, perform root-cause investigations and design-of-experiments where appropriate, and drive corrective actions and design iterations.
• Define module validation procedures, acceptance criteria, and technical documentation; support prototype delivery, customer evaluation, reliability assessment, and manufacturing readiness.

Qualifications & Experience:

The role requires broad product-level integration experience across optoelectronics, display electronics, semiconductor packaging, and optical systems. The engineer must be comfortable debugging hardware and working across disciplines, rather than owning only one subsystem.

Required:

• Bachelor’s degree in Electrical Engineering, Optical Engineering, Applied Physics, Materials Science, or a related technical field.
• At least 5 years of relevant experience in display module development, optoelectronic product development, semiconductor integration, or electronic hardware development.
• Hands-on experience integrating multiple hardware, semiconductors, or optoelectronic components into a functioning product or module.
• Experience with hardware bring-up, system debugging, performance characterization, and structured root-cause analysis.
• Ability to interpret engineering data, document technical findings, and coordinate resolution of issues across multiple engineering disciplines.
• Strong written and verbal communication skills and ability to manage multiple technical tasks in a fast-paced environment.

Preferred:

• Direct experience with MicroLED, LED, OLED, LCOS, or other microdisplay technologies.
• Experience with AR display modules, near-eye displays, optical engines, waveguides, or precision optical alignment.
• Familiarity with CMOS display backplanes, display driver ICs, pixel-driving architectures, and interfaces such as MIPI, SPI, or I²C.
• Experience with advanced semiconductor packaging, die bonding, wafer-level packaging, or fine-pitch hybrid bonding.
• Experience with driver boards, embedded hardware, display control firmware, and power-delivery considerations.
• Hands-on use of optical or electrical characterization equipment, spectrometers, imaging systems, or automated data-acquisition tools.
• Proficiency in Python, MATLAB, LabVIEW, or similar tools for engineering data analysis.
• Experience with product validation, reliability evaluation, yield improvement, design for manufacturability, or external suppliers.

Skills & Competencies:

• System integration: Understand interfaces and interactions among MicroLED devices, CMOS backplanes, packages, driver electronics, and optical subsystems.
• Troubleshooting: Isolate electrical, optical, mechanical, packaging, and firmware-related issues using a structured, data-driven approach.
• Analytical thinking: Correlate measured results with design and process variables; draw clear conclusions and recommend the next practical steps.
• Execution and ownership: Drive open issues to closure, manage competing priorities, and deliver prototypes and documentation on schedule.
• Collaboration: Communicate effectively with cross-functional teams, external suppliers, and engineering partners; make technical trade-offs clear.
• Attention to detail: Maintain accurate test records, interface specifications, build history, and validation results.
