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.

Raksul is a Japanese B2B e-commerce company that uses the internet to modernize traditional industries like printing, logistics, and advertising by creating efficient digital platforms, aiming to build "BETTER SYSTEMS, BETTER WORLD" through structural transformation and connecting customers with underutilized business resources. Originally a printing marketplace, it has expanded into a multi-faceted service ecosystem for small and medium-sized enterprises (SMEs) in Japan, offering services from custom merchandise to TV advertising and logistics, all under a unified ID. Raksul is expanding rapidly its business through new business launches, M&A, and global teams, while our core revenue platforms run on AWS, with a mix of legacy EC2-based systems and newer containerized services. Infrastructure decisions made today must remain valid as: 1. engineering organization grows from ~200 to ~400+ engineers globally, 2. teams become increasingly global and autonomous, and 3. platform complexity continues to increase. This is a player/coach role: approximately 60% hands-on technical execution and 40% strategy, stakeholder alignment, and people leadership (ratio may flex by quarter). You will lead the strategy, launch, and management of the cloud infrastructure, while also being hands-on in critical technical initiatives. A key near-term mission is to drive the transition of Infra Ops from a partner company and build and manage a distributed team across India and Japan to support that effort. You will work closely with multiple business units and product development teams to define the optimal infrastructure and development environment for the group, translate that into a technical roadmap, and guide the team to execute in a tangible and impactful way.
