• Infrastructure as Code (Terraform, Ansible)
• Observability & profiling (Prometheus, Grafana, eBPF, perf, ftrace)
• CI/CD and automation-first operations
• Low-latency networking and production troubleshooting
• Reliability engineering across trading-critical systems

Site Reliability Engineer – Key Skills Required

• 4–8+ years in SRE / Linux Engineering / DevOps / Infrastructure Engineering
• Strong Linux internals knowledge
• Experience supporting highly available, performance-sensitive systems
• Networking expertise (TCP/IP, UDP, Multicast)
• Automation and scripting experience (Python, Terraform, Ansible etc.)
• Experience with containers and modern observability stacks

Environment:

• Fast-moving trading environment
• High ownership and engineering autonomy
• Greenfield improvements and operational maturity projects
• Collaborative engineering culture with direct business impact
