Senior Site Reliability Engineer (SRE)

We’re a globally distributed team building a secure, standards-based OAuth/OIDC engine used by global businesses, digital banks, and regulated industries. Our API-first approach enables organizations to implement OAuth 2.0 and OpenID Connect with ease. 

We’re hiring a Senior Site Reliability Engineer (SRE) to improve the reliability, scalability, and performance of our platform and cloud offerings. This role is hands-on and focuses primarily on software engineering to solve reliability challenges across our stack. You will work closely with engineering teams to build tools, fix issues in production code, and keep our services running smoothly.

 

What You’ll Do

This is a hands-on engineering role. You’ll...

• Write and debug production code in Java, Go or Typescript, including fixes during incidents.
• Investigate application issues across test, staging, and production environments.
• Design, maintain, and optimize Kubernetes-based deployments across Shared Cloud, Dedicated Cloud, and Self-Managed deployment models.
• Develop and improve Helm charts as the standard deployment method across all supported environments.
• Manage and automate GitLab CI/CD pipelines, including container image packaging, and release processes.
• Enhance monitoring, alerting, and observability using Google Cloud Monitoring, Prometheus, and Grafana.
• Review and improve cloud functions and internal tooling written in Go, Ruby, and Bash.
• Participate in on-call rotations to maintain uptime and rapid incident response.
• Lead post-incident reviews and drive long-term reliability improvements.
• Collaborate with Engineering and Support teams to diagnose customer issues and optimize service quality.

 

What We’re Looking For

• Strong hands-on software engineering background and ability to write high-quality code.
• Experience debugging distributed systems and operating Kubernetes in production (preferably on GKE).
• Deep understanding of Kubernetes networking, security, Helm charts, and storage management.
• Proficiency in one or more programming languages such as Java, Go Typescript or Bash.
• Experience managing GitLab CI/CD pipelines and container image workflows.
• Ability to write PromQL alerting rules and interpret key reliability metrics.
• Familiarity with Redis, Liquibase, and TLS/mTLS certificate management.
• Experience with observability, incident management, and performance testing.
• Clear communication skills in English; Japanese language proficiency is a plus.
• Comfortable working independently in a distributed team across time zones.

 

Why Join Us

• Work closely with experienced engineers building a high-security, standards-compliant OAuth/OIDC engine.
• Solve complex reliability challenges across multi-cloud and self-managed environments.
• Be part of a lean global team where your contributions have direct product impact.
• Enjoy flexibility, autonomy, and the opportunity to shape infrastructure best practices.
• Competitive compensation, global collaboration, and meaningful technical challenges.
