Site Reliability Engineer

**About the company:** Zeals Meguro-ku, Tokyo We are a group of scrappy and hungry bunch from different walks of life, looking to make an actual impact on the way people and businesses communicate through our AI Chatbot technology. **Responsibilities:** Keep critical customer journeys reliable and available, and respond first when they aren’t. Join the on-call rotation for business critical services. Own alerting and observability: better coverage, fewer false positives, and catching issues before customers do. Build and operate in-house platform tooling: Kubernetes operators, custom Kubernetes APIs, GitOps automation, and deployment tooling that helps teams ship faster and safer. Eliminate toil by turning recurring developer requests into self-service, bringing an automation mindset to reduce complexity. Drive down platform cost without trading away reliability. Design infrastructure that scales with bursty, high-volume traffic, managed as code across many environments. Measure the platform against Well-Architected principles and act on what’s weak, whether that’s a reliability gap, an oversized resource, or a manual process worth automating. Requirements 3+ years in software engineering, SRE, infrastructure, or platform engineering on GCP or AWS. Hands-on Kubernetes experience: you can debug a workload, not just deploy one. Monitoring and observability experience (we use Grafana, Loki, Prometheus, and Thanos). Comfortable troubleshooting databases (we run MongoDB, Elasticsearch, and Postgres). CI/CD and GitOps experience (we use GitHub Actions, Helm, and Argo CD). Able to write and read code for tooling and automation (we use Go, Bash, and Python). Eligible to work in Japan, and business-level English. Nice to haves While not specifically required, tell us if you have any of the following. Terraform and infrastructure-as-code at scale. Go proficiency and experience building Kubernetes operators. Operating event-driven systems and high-throughput messaging at scale. Conversational Japanese.
