株式会社UPSIDER - 「挑戦者を支える世界的な金融プラットフォームを創る」
a business payment solution designed to simplify how companies manage spend.
Our Platform Team The Platform Team is responsible for delivering secure, reliable, and observable infrastructure that every engineer at the company depends on. We own the foundation — from release pipelines to cloud networking — so that product teams can move fast without breaking things. We are a CNCF Silver Member and active followers of the Cloud Native ecosystem. While day-to-day priorities mean contribution time varies, we value engineers who engage with the community and look to create more space for that as we grow. As a Platform Engineer, you will own and evolve key parts of our Cloud Native stack — including Kubernetes, Istio, the Grafana observability suite, ArgoCD, Terraform, and GCP-native services. You will research emerging technologies, make the case for adoption, and partner closely with development teams to support new and existing platform initiatives. We think about our systems across two dimensions: Pillars (technical ownership areas) - Network — service mesh, ingress, DNS, connectivity - Observability — metrics, logging, tracing, alerting - Data Store — managed databases, caching, storage - Environment Management — cluster lifecycle, provisioning, multi-tenancy - Automation — CI/CD, GitOps, self-service tooling Purpose (the lens we apply to every pillar) - Security - Reliability - Cost Efficiency - Developer Experience - Open Source Contribution You'll have room to develop a specialism, but the nature of platform work means you'll regularly cross all five pillars. Expect both depth and breadth.
