Guided by the belief that “digital technology can lead the way in solving social challenges,” we continue to take on new challenges in the rapidly growing IoT field, striving to remain a meaningful presence for our customers, society, and local communities.
As a creative collective that fuses digital technology with craftsmanship, we expand the possibilities of IoT and envision a future where people’s lives are enriched through innovation.
We are looking for new colleagues who will take on this challenge with us.
You will be responsible for selling a variety of solutions built around the EXBeacon Platform. These solutions are gaining attention as a new type of infrastructure service that spans offices and smart buildings, as well as factories, warehouses, hospitals, and even construction sites.
Your core responsibilities will include proposing and selling corporate and partner-focused solutions such as EXOffice (smart office), EXGateKeeper (biometric access control), building IoT, factory/warehouse solutions, and construction-site solutions (safety management, equipment and material management).
This position offers the opportunity to co-create new markets: leveraging evolving IoT technologies, collaborating with SIers and platform providers, and contributing directly to building and proposing entirely new business models and services.
Experience in sales or system engineering related to ICT/IoT devices, services, or systems
Motivated candidates with strong personal strengths are also welcome even without direct experience
Through your sales activities, you can develop deep expertise in the field. Depending on your strengths, interests, and ambitions, you may also expand into a wide range of roles across the company—such as product/service planning, solution engineering, project management, or customer support—allowing you to broaden your career in multiple directions.
As a Solutions Engineer, you will lead the implementation phase of our solutions—including EXOffice, EXGateKeeper, and various services built on the EXBeacon Platform. Your responsibilities will span requirement confirmation with customers, project planning, environment setup such as device and server configuration, testing and evaluation, on-site installation, and final validation.
In this role, you will work with cutting-edge technologies such as Bluetooth mesh while also engaging directly with customers throughout each project. Because project execution often leads to future business opportunities, we expect you to operate with a broad perspective and a strong sense of ownership across both technical and customer-facing aspects.
Practical experience as a system engineer in the development or implementation of ICT/IoT-related devices, services, or systems
Motivated candidates with strong personal strengths are also welcome even without direct experience
After gaining experience as a Solutions Engineer, you may grow into a Project Manager role—overseeing planning, and managing cost, quality, and delivery schedules.
Depending on your strengths, interests, and aspirations, you will also have opportunities to expand into various areas such as customer support, sales, and product/service planning and development, enabling you to build a diverse and evolving career.
You will develop our in-house smart office solution EXOffice and biometric access-control service EXGatekeeper.
Your primary responsibilities include:
This role focuses on developing our own products and services, so there is no customer-site dispatch or residency work.
You will collaborate closely with teams across sales, product planning, and solution engineering. We expect you to actively leverage evolving technologies—including AI—and contribute to planning, proposing, and developing new applications.
Practical development experience in any of the above environments (not all are required)
Motivated candidates with strong personal strengths are also welcome even without direct experience
After gaining experience as an Application Development Engineer, you may advance into roles such as Infrastructure Engineer or Site Reliability Engineer.
Depending on your strengths, aspirations, and interests, you may also expand into product/service planning, development, customer support, or sales—opening diverse pathways for future growth.
You will build and improve the infrastructure supporting our smart office solution EXOffice and our access-control service EXGatekeeper.
As an IoT platform handling high-load and large-volume data, continuous reinforcement of infrastructure is essential. Managing multiple parallel projects also requires scalable operational frameworks.
We actively design efficient, flexible systems by fully leveraging cloud technologies—driving serverless architecture, container orchestration, DevOps practices, and more.
This is an ideal environment for engineers who are eager to deepen their technical expertise.
Practical experience with development, infrastructure construction, or operations in any of the above environments (not all are required)
Motivated candidates with strong personal strengths are also welcome even without direct experience

Your responsibilities include:
We welcome candidates who have practical experience in developing electronic devices for commercial production, as well as those with limited experience who are motivated to build their expertise over the long term.
Preferred knowledge/experience includes (not all required):
Work under senior engineers on prototyping, evaluation, and documentation and learn the entire product development flow
Gain hands-on experience in circuit design, mechanical design, and firmware development depending on your strengths and interests
Lead hardware and firmware development for IoT devices
