Site Reliability Engineer

About the Role

The Site Reliability Engineer joins Mail Tactic’s Infrastructure & Reliability team to help us build and operate the production systems that developers and businesses depend on. You’ll work across our cloud infrastructure, observability stack, and on-call rotation to keep things running and improve them continuously.

This is a hands-on role. You’ll spend your time automating toil, improving reliability metrics, and shipping infrastructure improvements alongside the product engineering teams.

What You’ll Do

• Operate and improve Kubernetes clusters across multiple cloud environments
• Participate in the on-call rotation and own incident response from detection to resolution
• Build and maintain automated alerting, runbooks, and postmortem processes
• Reduce toil through automation using Python, Bash, and IaC tools
• Monitor SLOs and work with product teams to address reliability risks before they become incidents
• Improve CI/CD pipelines and deployment reliability
• Collaborate with security to harden infrastructure and implement best practices

What We’re Looking For

• 3–5 years of infrastructure engineering or SRE experience
• Solid Kubernetes experience — you’ve operated clusters in production
• Comfortable with Linux administration and cloud environments (AWS preferred)
• Experience with monitoring and alerting tools (Prometheus, Grafana, PagerDuty or similar)
• Good scripting skills in Python or Bash
• On-call culture: calm under pressure, thorough in postmortems
• Working knowledge of Terraform or similar IaC tools

Nice to Have

• Experience with OpenTelemetry and distributed tracing
• Familiarity with email infrastructure or high-throughput messaging systems
• Contributions to open-source infrastructure projects

What We Offer

• Fully remote, async-first — work from anywhere
• Competitive base salary + equity
• Annual learning & conference budget
• Home office stipend
• Flexible working hours, no core hours required
