Sr. Systems Engineer - job 16 of 33

As a Sr. Systems Engineer at Visa Technology & Operations LLC, your primary responsibilities will include providing infrastructure operations and production support for container technologies and orchestration platforms, particularly focusing on Docker and Kubernetes. You'll manage deployments, configurations, and scaling of containerized applications while ensuring the security and integrity of the Kubernetes cluster. Additionally, you'll collaborate with various teams to ensure seamless infrastructure support, participate in security remediation processes, and adhere to established ITIL practices.

For the Sr. Systems Engineer role at Visa Technology & Operations LLC, candidates typically need a strong background in systems engineering, with specific experience in container technologies such as Docker and Kubernetes. A degree in Computer Science or a related field is usually preferred, along with several years of relevant experience. Familiarity with ITIL practices and previous roles involving security remediation processes are also advantageous for prospective applicants.

Yes, the Sr. Systems Engineer position at Visa Technology & Operations LLC offers the potential for partial telecommuting. While the role is based out of the Highlands Ranch office, there are opportunities for flexibility, allowing you to balance in-office work with remote support depending on your responsibilities.

A Sr. Systems Engineer at Visa Technology & Operations LLC primarily works with container technologies and orchestration platforms, particularly Docker and Kubernetes. You'll also work with monitoring and auditing tools to harden and secure Kubernetes clusters, as well as ITIL practices for incident and change management, making familiarity with various infrastructure management tools essential for success.

Being on-call as a Sr. Systems Engineer at Visa Technology & Operations LLC means you'll be responsible for providing support to ensure the infrastructure operates smoothly, addressing any potential issues as they arise. This may include troubleshooting incidents, resolving system outages, and ensuring system integrity, all while collaborating with other teams to minimize downtime and maintain service levels.

To ensure the security of a Kubernetes cluster, I employ several strategies: I regularly update and patch the cluster to protect against vulnerabilities, implement role-based access control (RBAC) to limit permissions, and use network policies to control traffic flow. Additionally, I set up auditing and monitoring tools to track access and modifications, maintaining vigilance over any unusual activity.

I've worked extensively with Docker and Kubernetes, managing multiple deployments where I focus on creating efficient Docker images and orchestrating their deployment using Kubernetes. I've handled tasks such as scaling services, managing rollbacks, and coordinating with development teams to ensure smooth application delivery while maintaining high availability.

In my previous roles, I've implemented ITIL practices like Incident Management to ensure prompt resolution of issues, Change Management to control system changes effectively, and Release Management to streamline the deployment of updates. These practices have helped maintain service performance while promoting a culture of continuous improvement.

To manage scaling of containerized applications, I closely monitor application performance metrics and resource utilization. Using Kubernetes, I implement horizontal pod autoscaling, which allows the system to add or remove pods based on demand, ensuring optimal resource use while maintaining performance and reliability.

For vulnerability assessments, I start by conducting regular scans of the infrastructure using automated tools to identify potential weaknesses. Then, I prioritize findings based on severity, coordinating with the necessary teams to develop patch plans, and implement fixes in a timely manner to minimize risks to the organization.

When explaining complex technical concepts to non-technical staff, I focus on simplifying the language and using relatable analogies. I aim to highlight the relevance of the technology to their roles, ensuring they feel comfortable to ask questions and engage in discussions to enhance their understanding.

In a previous role, I faced a critical system outage due to a misconfiguration in the orchestration layer. I quickly assembled a cross-functional team, and we identified the issue through systematic troubleshooting. I maintained clear communication with stakeholders, resolving the incident efficiently, and afterwards implemented safeguards to prevent similar occurrences in the future.

I prefer using tools like Prometheus for metrics collection and Grafana for visualization, as they provide deep insights into the Kubernetes environment. Additionally, I utilize tools like ELK Stack for logging and alerting, which allows for proactive identification of issues before they escalate.

I approach collaboration with engineering and delivery teams by establishing open lines of communication and encouraging a culture of feedback. Regular stand-up meetings help me stay informed about ongoing projects, allowing us to align our goals and work together efficiently to address any challenges as they arise.

I have extensive experience with security remediation processes, where I often start by identifying vulnerabilities through assessments and scans. I collaborate with development and systems teams to prioritize and remediate these issues, ensuring compliance with best practices and maintaining the security posture of the organization.
