Design and build scalable backend services for energy-market products using Go, gRPC, microservices, GraphQL, GKE and Terraform. Remote work is possible.
About this role
Cloud Security Engineer role at an energy-market technology company operating Japan's largest online marketplace for energy trading, based in Minato-ku, Tokyo, with remote work available and full-time (seishain) employment. The company runs several products including a trading platform, a market-data platform, a trading risk-management tool, and a marketplace for environmental-value and carbon credits. The security function is being built out ahead of a planned listing, addressing gaps in in-house security expertise, risk visibility, and security investment. Main responsibilities: (1) design and establish the cloud security foundation; (2) build detection and response capabilities to prevent incidents and react quickly when they occur; (3) embed a DevSecOps culture to raise security across the whole product. The engineering environment uses React and TypeScript on the frontend; Go/gRPC and NestJS/GraphQL on the backend; PostgreSQL; Python for data engineering and analysis; Flutter for mobile; and a GCP-based infrastructure (GKE, Argo Workflows, BigQuery, Pub/Sub, Dataflow) with Terraform for infrastructure-as-code, Cloud Build/GitHub Actions/Argo CD for CI/CD, and Datadog for logging and monitoring.
