Vacant job

Polar Light Technologies is a fast-growing deep-tech startup developing next-generation photonic and semiconductor technologies to revolutionize the micro-LED industry. We are seeking a highly skilled System Integration Engineer to lead the development and integration of next-generation microLED display systems. In this role, you will bring together semiconductor devices, optics, electronics, software and advanced manufacturing processes to deliver high-performance microLED display modules. You’ll collaborate across multidisciplinary teams to drive concept development, system architecture, in-house prototyping, customer projects and industrialization of new solutions.

Key Responsibilities

• Define and optimize the end-to-end architecture of microLED display systems, including electrical, optical, mechanical, and thermal management
• Translate performance requirements (brightness, power, color) into system level specifications
• Drive process integration for chip bonding and alignment
• Work closely with R&D to improve yield and other performance parameters
• Collaborate with CMOS backplane designers to ensure signal integrity, current driving accuracy, and display uniformity
• Conduct circuit level validation and root cause analysis of electrical issues
• Integrate optical components such as microlenses, waveguides, and light management films
• Model thermal performance and implement effective heat spreader and dissipation strategies.
• Conduct reliability testing (aging, color shift, thermal cycling) and develop mitigation strategies for device and system level failures.
• Collaborate closely with semiconductor, optics, materials, mechanical, and manufacturing engineering teams within Polar Light Technologies and our customers
• Manage technical communication with external suppliers and manufacturing partners
• Develop prototypes to validate system performance
• Drive failure analysis and continuous design improvement

Required Qualifications

• Master’s or Ph.D. in Electrical Engineering, Optoelectronics, Physics, Materials Science, or similar
• 3+ years of experience in display technology, LED devices, semiconductor integration
• Strong knowledge of:
• LED device physics
• CMOS backplanes
• Optics and color science
• System engineering and root-cause analysis
• Hands-on experience with optical or electrical characterization equipment.

Preferred Qualifications

• Experience with InGaN/GaN-based microLED or MiniLED technologies
• Familiarity with advanced bonding processes
