About the role 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 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 products for target applications. Develop customer demos that effectively promote key features and benefits of 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 feedback to design teams to improve manufacturability, reliability, and integration readiness. About you 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.). 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).

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
