Principal Engineer

Company Description:JIITAK Inc. (株式会社JIITAK) is a rising software development studio headquartered in Japan, dedicated to sustainable system development. We prioritize delivering digital solutions that not only elevate our clients' businesses but also minimize our ecological impact. Our talented team, comprising skilled architects, designers, managers, coordinators, and developers, specializes in crafting custom, eco-conscious software solutions to meet our clients' needs. We develop frameworks and processes that empower teams to ship secure, scalable MVPs in record time.

In our pursuit of sustainability, we integrate these principles into every phase of our workflow, including planning, designing, and development processes. We firmly believe that digital solutions should align with and support the long-term health of our planet.

About the Role:

As a Principal Engineer, you’ll design and lead the evolution of a unified development framework that accelerates end-to-end MVP creation. Your work will span front-end (web/mobile), back-end, infrastructure, and quality assurance, ensuring seamless integration of best practices for UX, scalability, and DevOps. By balancing technical depth with strategic vision, you’ll empower teams to focus on innovation—not reinvention. We are redefining how products are built. Join us to architect the foundation that bridges innovation and execution for engineers, clients, and end-users alike.
