Organic Laser Device R&D / Organic Synthesis Engineer

Background of Recruitment

As XR devices and wearable healthcare devices become smaller and lighter, our technology is expected to be a key platform that brings new value to society. We have already conducted joint research and development with Mitsui Chemicals, Inc. and Sony Group Corporation, and in the near future, we aim to collaborate with global companies.

With accelerating technology development and business expansion, we are now entering a critical phase where we will fully launch business development efforts targeting display manufacturers and XR device makers. To lead these efforts, we are looking for a highly skilled engineer.

Although we are still a small team with limited resources, your work will have a direct and meaningful impact. This is an exciting opportunity where you can take ownership of your projects and see the results firsthand. If you are passionate about bringing a revolutionary Japanese technology to the world, we invite you to join us and shape the future!

Job Description

We are seeking a Materials Development Engineer with expertise in organic electronic materials design, synthesis, and characterization to drive the development of new organic semiconductor laser materials. This position will play a key role in leading materials innovation and bridging the gap between cutting-edge research and commercialization.

Key Responsibilities

• Design, synthesize, and evaluate new organic semiconductor laser materials to enhance performance and stability.
• Develop and improve testing and evaluation systems for organic semiconductor laser materials.
• Collaborate closely with the device team and external research partners to design and develop innovative organic semiconductor laser technologies that achieve the highest device performance.

Immediate Challenges & Focus Areas

Current Initiatives

Our technology originates from Professor Chihaya Adachi of Kyushu University, a world-renowned expert in organic EL (OLED) and TADF (Thermally Activated Delayed Fluorescence).

Based on academic demonstrations published in 2019, we established the fundamental blue device technology in 2023, achieving both directionality and monochromaticity. Currently, we are rapidly advancing the development of green and red devices.

By applying this technology to next-generation microdisplays, we aim to significantly enhance optical systems, making a major impact on the AR/VR industry. While we have focused primarily on emission device design, we now need an experienced materials engineer to help transition this breakthrough research into practical display solutions.

Target Industries

• OLED Manufacturers: Companies seeking to enhance OLED display performance and meet emerging market demands.
• Material Suppliers: Companies providing organic materials for OLED manufacturers.
• Semiconductor Companies: Firms involved in circuit design and manufacturing for micro-OLED silicon substrates.

Our Approach
