• Design, develop, and maintain highly reliable and scalable systems and infrastructure.
• Collaborate with software engineering and DevOps teams to ensure the smooth integration and deployment of applications and services.
• Implement and improve monitoring, alerting, and observability solutions to proactively identify and resolve potential issues.
• Automate infrastructure provisioning, configuration management, and deployment processes using modern tools and technologies.
• Conduct system performance analysis and optimization to ensure efficient resource utilization and optimal response times.
• Participate in incident response and resolution, conducting post-incident analysis and implementing preventive measures.
• Continuously evaluate and implement best practices and industry standards in site reliability engineering.
• Mentor and provide technical guidance to junior members of the team, fostering a culture of continuous learning and improvement.
• Collaborate with cross-functional teams to define and refine system requirements, capacity planning, and disaster recovery strategies.
• Work with the on-site operations team to ensure proper management, maintenance, and scaling of hardware components.
• Coordinate and perform occasional international travel to support deployments, infrastructure setup, and collaborate with remote teams.

• 9+ years of experience in a similar role, with a proven track record of designing, implementing, and managing highly available and scalable systems.
• Deep understanding of Linux/Unix systems administration and experience with cloud platforms (e.g., AWS, GCP, Azure) and containerization technologies (e.g., Docker, Kubernetes).
• Proficiency in at least one programming language (e.g., Python, Go, Java) and experience with infrastructure-as-code tools (e.g., Terraform, Ansible, AWS CDK).
• Strong knowledge of networking principles, including TCP/IP, DNS, load balancing, and firewalls.
• Experience with monitoring and observability tools (e.g., Prometheus, Grafana, ELK stack) and incident management systems.
• Solid understanding of distributed systems, microservices architecture, and cloud-native application development.
• Experience dealing with on-site operations teams, such as coordinating with the team for proper management, maintenance, and scaling of hardware components.
• Strong troubleshooting and problem-solving skills, with the ability to analyze complex systems and identify performance bottlenecks.
• Excellent communication skills, both written and verbal, with the ability to effectively collaborate with cross-functional teams.
• Willingness to travel internationally occasionally to support deployments and collaborate with remote teams.
• Experience with both production and internal tooling environments is desired.
• Relevant certifications (e.g., AWS Certified DevOps Engineer, Certified Kubernetes Administrator) are a plus. Experience working with SSO Providers (e.g., Okta, ADFS, etc) a plus
