Senior SRE/DevOps Engineer

About the Position

We’re hiring a Senior SRE/DevOps Engineer to own the reliability and infrastructure behind a real-time trading platform processing millions of events with strict latency expectations. You’ll design and operate production systems that engineers depend on to ship safely, with a focus on cloud, Kubernetes, observability, and disciplined infrastructure practices.

Responsibilities

• Design, maintain, and evolve AWS cloud infrastructure, including EKS, networking, IAM, and supporting services with focus on reliability, security, and cost control.
• Own Kubernetes workloads end-to-end: deployments, autoscaling, resource management, and cluster health across environments.
• Build and operate CI/CD pipelines with GitHub Actions to ensure fast, repeatable, and auditable releases.
• Maintain and improve the observability stack (Grafana, Loki, alerting) for fast issue detection and investigation.
• Own on-call and incident response processes: configure alerting, escalation policies, and drive post-incident reviews.
• Manage and scale Kafka-based streaming infrastructure supporting real-time data processing.
• Continuously improve system reliability through tuning, automation, and elimination of operational toil.
• Document infrastructure, incidents, and runbooks; ensure operational knowledge is shared and actionable.

Requirements

• Strong hands-on experience with AWS in production: VPC design, EKS, IAM, RDS, S3, CloudWatch.
• Deep expertise in Kubernetes: cluster operations, Helm, RBAC, resource optimization, and troubleshooting real workloads.
• Proven experience building and maintaining CI/CD pipelines with GitHub Actions, including multi-environment promotion, secrets management, and gated releases.
• Experience operating centralized logging solutions such as Grafana Loki (or equivalent), including index management, retention, and log-based alerting.
• Practical experience with Kafka: topic management, consumer monitoring, offsets, and performance tuning.
• Familiarity with ClickHouse or similar columnar databases in high-throughput environments.
• Hands-on use of Grafana for dashboards, alerting, and incident/on-call workflows with runbooks and escalation policies.
• Strong infrastructure-as-code skills (Terraform or equivalent) with version-controlled, peer-reviewed changes.
• Solid understanding of networking fundamentals: DNS, load balancing, TLS termination, ingress patterns, and basics of service mesh; experience with latency-sensitive systems and production ownership mindset.
• Upper-Intermediate English and strong communication skills.

Nice to Have

• Background in fintech, proprietary trading, or other high-stakes environments with strict uptime and data integrity requirements.
• Experience with service mesh technologies such as Cilium, Istio, or Linkerd.
• Familiarity with NATS, Redis, or other low-latency messaging and caching systems.
• Scripting skills in Python, Go, or Bash for automation and tooling.
