Role Overview

As a Senior SRE Engineer II at Ajaib, you own the reliability of production services and platforms end to end: observability, incident response, infrastructure as code, Kubernetes, releases and capacity. You work with product engineering teams to keep trading, payment and money systems available and fast, lead incidents when they happen, remove manual work through automation, and help the engineers around you grow.

• Own the reliability of services and platforms: define SLOs with product teams, track them and act when they are at risk.
• Build and improve monitoring, logging, tracing and alerting so that problems are found quickly and alerts are useful and not noisy.
• Be part of the on-call rotation, lead incident response, restore service quickly and run blameless post-mortems with tracked action items.
• Build and maintain cloud and Kubernetes infrastructure as code, with code review and safe rollout of every change.
• Improve CI/CD pipelines and release practices, including canary releases, automated rollback and safe database changes.
• Plan capacity for known peaks, such as market open and salary days, run load tests and keep cloud cost under control.
• Keep databases, Kafka and Redis healthy, with tested backups, failover and monitoring.
• Automate repetitive work with code and measure the toil removed.
• Run recovery tests and game days for the systems you own, and keep runbooks accurate.
• Work with Security and Compliance on access control, secrets management, patching and audit evidence.
• Review production readiness of new services and give clear reliability guidance to engineering teams.
• Mentor mid-level engineers and share knowledge within the team.

Requirements

• Education: Bachelor's degree in Computer Science or equivalent practical experience.
• Experience: 5+ years of professional engineering in SRE, DevOps, infrastructure or platform roles, including on-call ownership of production systems with real traffic.
• Reliability Engineering: Solid understanding of SLOs, incident management, capacity planning and resilience patterns.
• Observability: Hands-on experience with monitoring, logging and tracing tools such as Prometheus, Grafana, Datadog and OpenTelemetry.
• Infrastructure: Strong experience with Kubernetes, infrastructure as code (Terraform) and a major cloud platform (GCP or AWS).
• Automation & Languages: Good programming and scripting skills in Go, Python or Bash, used to build tools and automation.
• Systems Fundamentals: Strong Linux, networking (DNS, TLS, load balancing) and troubleshooting skills.
• Data & Messaging Operations: Working experience operating relational databases, Kafka or Redis.
• Mindset & Domain: Ownership mindset and clear communication. Experience in fintech or another regulated, high-traffic environment is a strong plus.
