About the position

The CTO Office is driving the development of Atlas, an AI-based ontology architecture for enterprise customers, as well as the design and development of shared foundations and platforms that enable the organization to scale.

Atlas is built around an ontology: a next-generation, AI-based semantic layer that can understand context across business data, workflows, and operations.

We are looking for a full-stack engineer who can help drive the development of this next-generation architecture, with a particular focus on backend systems.

This means that we are responsible for many things, including:

• Developer tooling.
• CI / CD systems.
• Building core platform infrastructure.
• Analyzing and improving infrastructure performance.
• Socio-technical problems like improving developer culture by leading through example
• and developing tooling to solve problems.
• A good description of the role is that it is similar to an SRE/Devops position, with more
• focus on coding rather than operations.

You have a lot of freedom to make things better, but are expected to take initiative to find places to apply this freedom and improve things at an organization-wide level.

• TypeScript everywhere.
• NodeJS.
• React.

Requirements

• A comfortable, senior level understanding of cloud infrastructure (e.g. AWS, distributed systems).
• Production experience working with observability / monitoring platforms (we use DataDog).
• Strong programming experience (e.g. equivalent to a Senior full stack engineer).
• Ability to communicate in English. You do not need to be fully fluent, but should be comfortable communicating in English as part of the role.
• A strong dedication to code quality, documentation, and automated testing.
• Initiative to find their own work and act on it.
• Willing to wear many hats and get involved in any software system in the company.
• Either be conversational Japanese, or a desire to do so (we will help).
• Be located in, or be willing to relocate to Japan (we will re-locate). Please be sure to no
