Job Description

Overview:

We are seeking a talented and experienced Site Reliability Engineer (SRE) to join our Containers Platform Team. As an SRE on the team, you will play a critical role in ensuring the reliability, scalability, and performance of our containerized infrastructure, enabling our tenants to deploy and manage their applications with confidence. You will work closely with cross-functional teams to design, implement, and maintain complex systems that power our cloud platform.

In addition, the candidate must utilize technical skills, effective communication, problem-solving abilities, and the ability to work well on a fast-paced team. Continuously staying updated with the latest trends and advancements in container technology and cloud ecosystems to keep the infrastructure reliable and efficient.

Responsibilities:

• You will be responsible for the deployment of containerized applications across a cluster of bare-metal servers, facilitating automatic scaling of containerized applications based on demand, and managing utilization of compute resources such as CPU, memory, and storage across the cluster.

• Implementing monitoring solutions (e.g., Prometheus, Grafana) to track the health and performance of bare metal clusters and infrastructure components. You should be able to set up alerting mechanisms to detect and respond to issues proactively and recover from failures by restarting failed containers or reallocating workloads to healthy nodes.

• Working closely with development and engineering teams to establish CI/CD pipelines for automating the deployment and rollout of Kubernetes services. Support seamless rolling updates allowing new versions to be deployed gradually while maintaining application availability.

• Identifying performance bottlenecks in containerized environments and optimizing resource utilization through capacity planning, auto-scaling, and performance tuning.

• Documenting processes, procedures, and best practices related to the platform operations and sharing knowledge with team members.

Qualifications

• Bachelor’s degree in computer science or a related field, or equivalent experience, typically 5+ years in a Site Reliability Engineering, DevOps, or Systems Engineering role.

• Cloud platform administration experience required.

• Must be proficient in containerized technologies such as Kubernetes, containerd, and/or nerdctl. This includes the ability to deploy, manage, and scale containerized applications effectively.

• Experience implementing continuous integration and continuous delivery (CI/CD) tools and systems.

• Intermediate to advanced proficiency in programming languages such as: Go (Golang), Shell scripting (Bash), and familiarity with YAML/JSON.

• Automation scripting with tools such as ansible playbooks or similar imaging solutions.

• Advanced understanding of networking fundamentals, including TCP, DNS, UDP, IPv4/IPv6 networking, Load Balancing, and protocols. Understanding IP networking and traffic scaling is also important.

• Proven ability to design and present understandable and practical solutions to complex problems.

• Strong verbal and written communication skills are essential. This includes the ability to effectively communicate technical concepts, as well as the ability to create clear and informative documentation.

• Ability to work effectively across internal and external organizations.

• Flexibility to work off-hours for on-call duties. SREs are often responsible for maintaining the reliability and availability of systems outside of standard working hours, so the ability to respond to incidents and perform maintenance tasks as needed is required.
