We’re looking for an experienced Senior Site Reliability Engineer (SRE) who can write production-grade code, have mastery of SLIs, SLOs, and error budgets, and are passionate about building scalable observability systems.

• Can code confidently in Python or Golang and solve real-world problems through automation. (not only scripting)
• Have hands-on experience implementing SLIs, SLOs, and distributed tracing in production.
• Understand Kubernetes, Terraform, and Infrastructure as Code tools.
• Have hands-on experience with Chaos Engineering and anomaly detection.
• Are excited about working with high-throughput, distributed systems processing millions of transactions daily.

• Design, implement, and manage SLOs, SLIs, and error budgets, ensuring reliability aligns with user expectations and business objectives.
• Develop production-grade software to enhance system reliability and reduce manual toil through automation.
• Implement and optimize observabilitysolutionsusing tools like Open Telemetry, with a focus on high-cardinality metrics, distributed tracing, and actionable insights.
• Drive postmortem processes and lead in-depth root cause analyses for incidents, ensuring lessons learned are effectively applied to prevent recurrence.
• Define and monitor MTTx metrics (MTTA, MTTR, MTTF), using them to guide system improvements and measure reliability progress.
• Design and participate in Chaos Engineering exercises.
• Collaborate with engineering teams to design systems with reliability and scalability in mind, incorporating capacity planning, resiliency patterns, and modern deployment strategies (e.g., Canary, Blue-Green).
• Lead design reviews for alerting strategies, ensuring effective signal-to-noise ratios in monitoring and incident management.
• Advocate for and implement best practices in incident response and system design to achieve optimal uptime and performance.

• 4+ years of experience as an SRE or in a similar role with hands-on coding.
• 3+ years of software development experience in Python or Golang, with a focus on building maintainable, production-quality code.

• Deep understanding of SRE principles, particularly SLIs, SLOs, error budgets, and their real-world application.
• Hands-on experience conducting postmortems and implementing observability at scale.
• Hands-on experience conducting chaos engineering exercises.

• Expertise in designing and implementing end-to-end observabilitysolutions using tools like Open Telemetry, Prometheus, Grafana, or Honeycomb.
• Experience with distributed tracing and handling high-cardinality metrics in production environments.

• 3+ years of experience with AWS and proficiency in Kubernetes, Terraform, and Infrastructure as Code (IaC) tools.
• Strong understanding of distributed systems, microservices architectures, and containerization (Docker, Kubernetes).

• Hands-on experience with CI/CD platforms (Git Ops, Jenkins, ArgoCD) and building automated pipelines.
• Familiarity with tools and frameworks for incident management and operational automation.

• Knowledge of modern deployment strategies (e.g., Canary,Blue-Green) and resiliency patterns (e.g., circuit breakers, retries).
• Strong analytical skills for…
