• Own reliability improvements end-to-end, from investigation and design through delivery and follow-up.

• Identify recurring operational problems and deliver durable solutions that improve reliability, scalability, and performance.

• Contribute to design and code reviews, raising reliability, security, and operability risks early.

• Improve metrics, logs, traces, alerts, deployment safeguards, and recovery automation.

• Partner with product engineering teams to improve service health and adopt safe self-service capabilities.

• Participate in the 24/7 on-call rotation for business-critical services and lead technical response in your area.

• Lead or contribute to incident reviews and complete follow-up actions that reduce recurrence and impact.

• Share knowledge, improve runbooks, and mentor engineers in reliability practices.

• Automate client onboarding, deployments, and disaster recovery execution

Requirements: Experience

• 3+ years of experience in Site Reliability Engineering or a closely related role.

• Strong understanding of cloud networking, distributed systems, and service architecture.

• Experience writing tested, maintainable production code in Python, Go, Java, Kotlin, Scala, or a comparable language.

• Hands-on experience with AWS, Docker, GitHub Actions, Terraform, and Kubernetes, ECS, or EKS.

• Experience with observability, CI/CD, production automation, and infrastructure as code.

• Understanding of cloud security and identity management, including AWS IAM and Active Directory.

• Experience applying SLIs, SLOs, and SLAs to assess service health and guide engineering priorities.

• Ability to troubleshoot complex systems and turn operational problems into maintainable software or automation.

• A degree in Computer Science, Information Technology, or a related field, or equivalent professional experience.

• Most importantly, a desire to learn, grow, and collaborate with a thoughtful engineering team.

What you can look forward to

• Remote role with a distributed team across multiple time zones but you will be covering APAC primarily.

• Work closely with engineering teams on services that support global payments.

• Meaningful ownership of reliability improvements from discovery through production.

• Support for your ongoing career growth and development.

• A diverse, collaborative, mission-driven engineering culture.
