Define and drive the SRE strategy, roadmap, and standards across engineering teams
Establish and enforce SLOs, SLIs, and error budgets across all production services
Own the incident management lifecycle — detection, response, resolution, and prevention
Lead blameless postmortems and translate findings into lasting systemic improvements
Manage on-call rotations and aggressively reduce toil through automation
Lead the design and evolution of large-scale, distributed systems and platform infrastructure
Define technical standards, architectural patterns, and engineering best practices org-wide
Evaluate and recommend technologies and tooling aligned to business and reliability requirements
Conduct architecture reviews and provide guidance on complex technical trade-offs
Lead capacity planning, performance engineering, and infrastructure scaling strategies
Build and maintain highly available, fault-tolerant infrastructure on cloud platforms (AWS/GCP/Azure)
Drive infrastructure-as-code adoption (Terraform) and enforce best practices
Architect and implement observability platforms — metrics, logging, tracing, and alerting
Build and improve CI/CD pipelines, deployment automation, and release engineering workflows
Lead chaos engineering and game day exercises to validate system resilience
Champion automation across provisioning, testing, deployment, and monitoring workflows
Mentor and grow a team of SREs, platform engineers, and systems engineers
Partner with DevOps, security, and product teams to align on shared platform goals
Serve as the technical escalation point for critical infrastructure incidents and outages
Communicate complex technical concepts clearly to non-technical stakeholders and leadership
Contribute to build vs. buy evaluations and drive strategic vendor assessments

Requirements

8+ years of experience in SRE, systems engineering, platform engineering, or DevOps roles
3+ years in a senior or lead capacity with ownership of large-scale, distributed systems
Deep expertise in at least one major cloud provider — AWS preferred
Strong proficiency in Python, Go, Bash, Java, or C++
Hands-on experience with Kubernetes, container orchestration, and service mesh technologies
Solid understanding of Linux/Unix internals, networking (TCP/IP, DNS, TLS/SSL, load balancing)
Proficiency with observability tooling: Datadog, Prometheus/Grafana, Splunk, or equivalent
Proven track record defining and operating against SLOs and error budgets
Experience with infrastructure-as-code tools — Terraform required
Strong understanding of distributed systems design, security fundamentals, and data governance
Experience with service mesh (Istio, Linkerd) and API gateways (Kong, Apigee)
Background in systems integration across enterprise middleware, ERP, or CRM platforms
Familiarity with FinOps practices and cloud cost optimization
Experience in regulated industries: financial services, automotive, healthcare, or government
Familiarity with compliance frameworks: SOC 2, ISO 27001, or NIST
Track record of leading migrations — legacy-to-cloud or monolith-to-microservices
Relevant certifications: AWS Solutions Architect, CKA/CKAD, GCP Professional, or Red Hat RHCA
Must clear a pre-employment drug test (marijuana testing excluded)
