About ATI

What We Value

We dive deep into our clients' businesses with overwhelming ownership, delivering value through engineering while eliminating the "unhappiness" that can surround the craft.

Partnership with Overwhelming Ownership

We engage with businesses as our own, transcending roles so that everyone involved in web and IT can face essential challenges. Engineers themselves drive everything from problem identification to improvement proposals, pursuing both quality results and fulfilling work.

Zero Distance Between Field and Management

Management including founding members still write code on the front lines, conducting design reviews and handling incidents. We ensure engineer-first decisions through speedy decision-making based on field awareness.

Project Selection Focused on Essential Value

We stand beside clients from design through delivery to address essential challenges. We decline projects with vague purposes or unrealistic schedules, building a healthy environment that sustains continuous growth.

Open Positions at ATI

We recruit across multiple specialties to solve business challenges with technology. We welcome people who act as true stakeholders, envisioning the value they want to deliver from a product perspective beyond years of experience.
