Role Description

We are expanding our Site Reliability Engineering (SRE) team and seeking a highly skilled and passionate Senior SRE to join us. As a member of our growing SRE function, you will play a critical role in ensuring the reliability, scalability, and performance of our mission-critical services that power our customer experience. This is an exciting opportunity to shape our SRE practices, drive automation, and significantly impact our product's operational excellence.

• Drive Operational Excellence: Design, implement, and maintain highly available, scalable, and resilient systems that deliver exceptional customer experience.
• Datadog Expert: Be one of the go-to experts for Datadog, responsible for defining, implementing, and enforcing best practices for monitoring, alerting, logging, tracing, and synthetic testing across our entire AWS environment.
• Software Development for Reliability: Develop robust, well-tested, and maintainable software and tooling to automate operational tasks, create self-service capabilities for engineering teams, and enhance system reliability.
• Toil Reduction Champion: Identify and eliminate toil through automation, process improvements, and systematic problem-solving.
• Incident Management & Post-Mortems: Contribute to and evolve our incident response framework, participating in on-call rotations (using OpsGenie) and leading blameless post-mortems.
• Reliability Metrics & Goals: Collaborate with engineering teams to define, implement, and track Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Error Budgets.
• Infrastructure as Code: Leverage and contribute to our infrastructure as code (IaC) efforts, moving towards a fully automated environment using Terraform and GitHub Actions.
• System Design & Architecture: Provide SRE expertise in system design reviews, influencing architectural decisions to build reliability, observability, and scalability into our services.
• Knowledge Sharing & Mentorship: Document processes, build runbooks, and share your expertise with both the SRE team and broader engineering organization.

Qualifications

• Demonstrated experience operating and improving production systems at scale in an SRE, Production Engineering, or Platform Engineering role.
• Proven ability to rapidly build accurate mental models of complex distributed systems across infrastructure, applications, networking, identity, and observability domains.
• Strong troubleshooting skills with a methodical, evidence-driven approach to incident response and root cause analysis.
• Experience defining, implementing, and using Service Level Indicators (SLIs), Service Level Objectives (SLOs), and error budgets to guide reliability decisions.
• Excellent written and verbal communication skills, with the ability to explain complex technical issues clearly to both technical and non-technical audiences.
• Experience across several of the following areas:
• Kubernetes platforms, including Amazon EKS, and service mesh technologies such as Istio.
• Cloud infrastructure and services within AWS.
• Identity and access management systems, including Auth0 and AWS IAM.
• Networking fundamentals, including DNS, load balancing, routing, TLS, and connectivity troubleshooting.
• GitOps workflows and infrastructure automation using tools such as Flux and Terraform.
• Observability platforms and practices, including metrics, logs, traces, alerting, dashboards, and synthetic monitoring.
• CI/CD systems and engineering workflows.
• Application logging and distributed system debugging.

Requirements

• A strong SRE prioritizes service stability and customer impact during incidents.
• Slows down under pressure, gathers facts, and communicates clearly.
• Reduces operational complexity through automation and simplification.
• Identifies and eliminates toil through self-service tooling and process improvement.
• Demonstrates strong scripting and automation instincts.
• Brings a systems-thinking approach to problem-solving.
• Balances short-term remediation with long-term reliability improvements.
• Demonstrated ability to build and maintain automation, tooling, and self-service capabilities using one or more programming or scripting languages such as Python, Go, or Bash.
• Focuses on applying software engineering practices to improve reliability, reduce toil, and enhance developer productivity.

Benefits

• Calm and effective during high-severity incidents.
• Skilled at managing complex situations involving multiple teams and competing priorities.
• Able to lead blameless post-mortems and drive meaningful follow-up actions.
• Passionate about continuous improvement and fostering a culture of shared ownership.
