Full-Stack Development of AI Products | Web Engineer Working Directly Under the CTO

[Open Position]
We are a University of Tokyo AI startup selected for "GENIAC," a national project run by the Ministry of Economy, Trade and Industry (METI) and NEDO. You will join frontline projects that support business growth through technology, taking end-to-end ownership of developing web solutions specialized in problem-solving.
[Main Responsibilities]
- Developing sales demos and mockups at the PoC stage
- Formulating requirements definitions in collaboration with PMs
- Product development using Next.js, Python, and other technologies (frontend and backend)
- Deploying to client environments and providing operational maintenance
- Quality assurance and creating customer-facing materials
You will develop these and more under the mentorship of our experienced engineers, making full use of a modern technology stack.
Because you will flesh out specifications and propose improvements while hearing directly from customers, you will sharpen not only your technical skills but also the communication skills to guide business problems to resolution. Embody the mindset Airion values—"speed first," "output that exceeds expectations," and "last-man spirit"—as we create the future of our customers' businesses together.
[Highlights]
- Experience product development that solves real business problems—something you cannot get through self-study
- Participate end to end in every phase of development, from the "0 to 1" planning stage through design, implementation, and deployment
- Experience a hands-on development cycle with close client contact, iterating rapidly on direct feedback
- At a growing company, become one of the people who shape the culture of the engineering organization
[Growth Opportunities]
- Acquire practical development skills under attentive mentorship from experienced engineers
- Build a business perspective by owning everything from problem discovery to resolution, not just technical skills
- Develop the ability to drive projects autonomously through design and development work with broad discretion
- Gain diverse experience that feeds directly into your future career by engaging broadly, from implementation to client negotiations
[The Mindset We Value]
- A hunger to absorb new technologies
- A commitment to managing your work with speed as the top priority
- A drive to deliver output that exceeds the expectations of stakeholders inside and outside the company
- Last-man spirit: owning the projects you are responsible for through to the end
- Boosting productivity through frequent reporting, updates, and consultation, and close communication
