About the Company

Inlighten Technologies is a Silicon Valley startup developing next-generation microLED technologies for augmented reality (AR) and AI-powered smart glasses. Our mission is to push the limits of microLED performance and manufacturing, enabling scalable, mass-market production. Join us to help create the displays that will power the future of immersive computing.

Description

We are seeking an Application Engineer who can bridge the gap between display technology and system integration. You’ll work closely with display, optical, electrical, and software teams — as well as external partners to integrate, test, and optimize our microLED displays within AR glasses platforms.

The ideal candidate understands how displays and light engines interact with optical systems, has a strong grasp of waveguides, and is experienced in debugging hardware–software issues in complex optoelectronic systems.

Key Responsibilities

• Provide guidance and consult with customers on light engine design concepts and solutions to optimize their AR display system performance.
• Provide expert technical support to Inlighten customers, addressing field application issues, system performance troubleshooting, system solutions design-in support, and partner management in collaboration with the sales organization.
• Create technical collateral in cooperation with the product marketing team, including application notes, white papers, PowerPoint training modules, performance calculators, and reference designs that demonstrate the value proposition and competitive advantage of Inlighten products for target applications.
• Develop customer demos that effectively promote key features and benefits of our products.
• Serve as the primary technical point of contact for key customers, providing guidance and support throughout the product development lifecycle.
• Provide timely resolution to customer inquiries, issues and concerns, ensuring high levels of customer satisfaction.
• Collaborate with software and firmware teams to diagnose and resolve display-related issues (timing, drivers, communication, image artifacts, etc.).
• Support customer and partner engagements by demonstrating system functionality and addressing technical inquiries.
• Provide timely resolution to customer inquiries, issues and concerns, ensuring high levels of customer satisfaction.
• Provide feedback to design teams to improve manufacturability, reliability, and integration readiness.

Minimum Qualifications

• BS/MS in Electrical Engineering, Optical Engineering, Physics, or related field.
• 3+ years of hands-on experience working with displays, LEDs, optoelectronics, or semiconductor devices.
• 5+ years of experience in display systems, AR/VR devices, or optoelectronic hardware integration.
• Prior experience supporting demo environments, developer hardware, or early-stage XR prototypes.
• Strong understanding of display technology, light engines, and waveguide optics.
• Proficiency in debugging hardware-software interactions — familiarity with firmware, display drivers, and embedded interfaces (MIPI, SPI, I2C, etc.).

• Must be professional, detailed, customer-oriented, self-driven and able to collaborate with interdisciplinary teams to meet customer needs.
• Excellent problem-solving skills and ability to thrive in a startup environment where priorities evolve quickly.
• Strong ability to influence with excellent interpersonal skills and ability to analyze, summarize, and communicate efficiently (written and verbal) in a multicultural environment.

• Ability to travel up to 50% of the time (including international events).

Preferred Qualifications

• Advanced degree (MS or PhD) in a relevant field of study.
• Previous work in commercially available AR glasses
• Comfortable with Python, MATLAB, or C/C++ for data analysis.
• Hands-on experience with optical testing equipment (spectrometers, cameras, light measurement tools).
• Pre-sale and marketing experience.
• System/Architecture experience.

Benefits & Perks

• Comprehensive health, dental, and vision insurance.
• 401(k) retirement plan.
• Paid holidays and vacation.
• Employee stock option plan.
