Proactively review the applications APIs and processes to identify opportunities to optimize the response times for various application components. Automate various types of testing including data quality checks, automate delivery to production and automate deployment for production Develop integrations between the application in On-premises and AWS and our third-party tools (ServiceNow, VersionOne, Sumo) Work with teams to create SLI/SLOs Actively monitor and lead troubleshooting of degraded performance and hard to define issues for the platform applications, develop the solution and document artifacts in the back log from root cause analysis. Evolve the cloud infrastructure ecosystem for our application suite by experimenting with emerging technologies and completing prototypes to understand benefit Design and develop CI/CD pipeline to deploy various application artifacts, including APIs and Data Process Jobs. Analyze, design, and develop the artifacts to configure the monitoring and alerting metrics so the support engineers can proactively and timely validate, troubleshoot and resolve the issues. Maintain data integrity and access control by using AWS security tools and services such as HSM, IAM, etc. Understand and develop tools to monitor AWS billing for the services, generate cost related reports and help develop and implement cost optimization strategies. Work with enterprise security architects to design and implement data security tools, measures, data encryption, key management; design and develop solutions to address the security vulnerabilities discovered by internal security audit team, as well as by the vendors, security community, etc.; design and develop solutions for support team to regularly scan and review to fix security issues Regularly and proactively monitor and analyze the capacity and performance of the platform, work with the architecture team to design and implement elastic infrastructure to accommodate the irregular burst of user traffic/requests. Work with the architecture team to develop a backup strategy and implement the backup solution for critical data and application components for service restoration and disaster recovery purposes. Work with architecture, infrastructure, and application teams to provide input on continuous improvement on the design, performance, and security enhancements. Desired Skill Set: Deep understanding of the operations of AWS cloud platforms. Must be well versed in the automation, scripting, monitoring, including use of tools from the major cloud platforms, including but not limited to OpenShift Cloud Formation, Terraform, Ansible, Shell, Python Preferable for candidates with significant technical knowledge with infrastructure layers, including but not limited to: Linux OS, major virtualization platforms, Traditional and software defined network, Load Balancers, firewall, API tools, element/performance/intelligent monitoring tools, storage, backup strategy, etc. Significant knowledge and experience in end-to-end operations for enterprise systems and applications, including driving issue resolution for mission critical systems. Must have experience working to automate, operationalize and improve the Development/QA using CI/CD tools (Gitlab, Github, Jenkins, Maven, Gradle, Nexus) Working experience with Software Release Management. Desired Qualification BS degree in Computer Science or a related technical field or equivalent practical experience. Minimum Experience 3+ years of related DevOps, SysOps engineering experience with focus on major cloud platforms (AWS preferred). 2+ years of application development experience including data streaming, deploying/monitoring high availability critical application components. 1+ Years in Site Reliability Engineering organization preferred Overall 7+years of experience Responsibilities: Engage in and improve the whole lifecycle of servicesfrom inception and design through deployment, operation, and refinement. Responsible for improvements to end-to-end availability and performance of mission critical services and build automation to prevent problem recurrence. Partner with business and technical product owners to set SLOs / SLIs / error budgets to manage reliability of infrastructure and applications Scale and optimize existing infrastructure and services sustainably through mechanisms, including automation, and evolve them by improving reliability and efficiency. Manage end-to-end availability and performance of mission-critical services and build automation to prevent problem recurrence Maintain infrastructure (infrastructure as code) and services by measuring, and monitoring system metrics to proactively identify operational efficiencies, potential outages, and security threats in Development, UAT, Staging and Production environments. Practice sustainable incident response and blameless postmortems Build infrastructure and drive projects that break things with the aim to improve the robustness of production systems Preserve operational visibility and response capabilities fixing and improving our dashboards, alerts, and automation. Maintain operational uptime and reliability by participating in triage and issue support calls for mission critical systems. Monitoring service-level indicators (SLIs). An SLI could be the number of successful requests out of total requests. Having a high SLI, in this case, would be a target. SREs track other metrics such as availability, uptime performance, latency, error count and throughput. Regularly monitoring systems is essential to ensure proper resource utilization of containers and to avoid out-of-memory (OOM) errors. Setting SLOs and SLAs and determining error budgets. Once you have determined baseline system performance, you can set service-level objectives (SLOs). These are typically internal targets like 99.99% availability. While SREs typically oversee functional metrics, some teams set goals for non-functional metrics, as well. SREs help determine service-level agreements (SLAs), which are more legally binding and typically partner-facing. Responding to incidents. On-call SREs will be tasked with finding the root cause of issues as they arise. When triaging an incident, its helpful to have all the necessary logs and tools immediately at hand. This is one area where automation can assist by pulling relevant details to instantly build a case, said Curtis. Writing postmortems. After an incident has been dealt with, its important to learn from it. Postmortems are common in cybersecurity practice and often fall under the responsibility of an SRE. These reviews seek to answer set criteria to get to the heart of an incident and identify the root cause(s) of an issue to prevent it from happening again.
