- Automate recurrent operational tasks using scripts (e.g., Python) and Infrastructure-as-Code tools (e.g., Terraform)
- Collaborate with engineers to build highly available, reliable, deployable systems, establishing guardrails around SLOs, SLIs, and error budgets
- Own incident response by participating in on-call rotations, conducting RCAs, and implementing preventive measures and self-healing solutions
- Conduct performance tuning, capacity planning, and efficient disaster recovery design for strong Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO)
- Reduce manual toil in security compliance and patching processes through automation
- Support project teams in troubleshooting and resolving operational issues across development, testing, and production environments
- Provide guidance and operational support during project rollouts and infrastructure changes to ensure reliability and uptime
- Collaborate with senior stakeholders, internal and external, to communicate technical concepts, resolve problems, and influence decision-making on technical matters
- Work closely with the product team to stay informed about evolving system design, business logic, and transaction flows to ensure reliability and operational readiness across services
- Identify and address organization-wide gaps in the SRE domain and develop implementable solutions that contribute to reliability and operational excellence

Required Qualifications

- 10+ years as an SRE, DevOps, or related role managing large-scale solutions or platforms
- Proficient in scripting (PowerShell, Python, Go, Bash) and solid understanding of coding/development principles
- Hands-on experience with cloud platforms (AWS, GCP, Azure) and container orchestration (Docker, Kubernetes)
- Experienced with monitoring, logging, alerting, and observability tools
- Familiar with CI/CD pipelines and infrastructure tooling (e.g., Jenkins, GitLab CI/CD, Argo CD)
- Proficiency in Agile methodologies, such as SCRUM
- Strong problem-solving and debugging skills, especially in high-pressure, production-critical environments
- Strong collaboration and communication skills

Desired Qualifications

- Bachelor's degree in Systems Engineering, Computer Science, Electrical Engineering, or related field.
- Experience with Terraform and other Infrastructure-as-Code tools
- SRE-specific certifications from AWS, GCP, or Azure
