Senior Software Engineer — Platform (Atlas)

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. Our Tech Stack Not exhaustive, but the most important are: TypeScript everywhere. NodeJS. React. MongoDB. AWS (Specifically ECS, CloudFront, S3, SQS, Lambda) Vercel. Redis. 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 t in your application if you’re already based in Japan or not. Nice to haves While not specifically required, tell us if you have any of the following. Experience programming in a typed language (TypeScript is ideal). Experience with CDK-TF (or good Terraform experience).
