Site Reliability Engineer • Senior

Who you are

You are an experienced Site Reliability Engineer with a strong background in maintaining and improving the reliability of complex systems. With 5+ years of experience in a similar role, you have a deep understanding of observability, monitoring, and incident management — you've successfully implemented tools and processes that enhance system stability and resilience. Your expertise in cloud platforms, particularly AWS, allows you to design and manage scalable infrastructure that meets the demands of high-traffic applications.

You possess strong troubleshooting skills and can quickly diagnose and resolve live production issues — your analytical mindset helps you to proactively detect potential problems before they escalate. You are comfortable working in a collaborative environment, where you can share knowledge and mentor junior engineers, fostering a culture of continuous improvement and learning.

Your technical skills include proficiency in containerization technologies like Docker and orchestration tools such as Kubernetes — you understand how to leverage these tools to streamline deployment processes and improve system performance. You are also well-versed in using monitoring and alerting tools like Prometheus and Grafana to ensure that systems are operating optimally.

Desirable

Experience with infrastructure as code tools such as Terraform or CloudFormation would be a plus, as would familiarity with CI/CD pipelines and automation frameworks. You are always eager to learn new technologies and methodologies that can enhance your team's capabilities and improve operational efficiency.

What you'll do

In this role, you will be a key member of the Platform Site Reliability Engineering (PSRE) team, responsible for ensuring the stability, reliability, and availability of mission-critical production applications on the Arcesium platform. You will implement observability practices, including monitoring, logging, and tracing, to proactively detect and prevent issues that could impact system performance.

You will build and maintain tools and infrastructure that enhance system stability and resilience, working closely with development teams to ensure that applications are designed with reliability in mind. Your responsibilities will include troubleshooting live production issues, focusing on rapid incident resolution, and conducting post-mortem analyses to identify root causes and prevent future occurrences.

You will collaborate with cross-functional teams to improve operational processes and contribute to the development of best practices for incident management and response. Your role will also involve mentoring junior engineers, sharing your expertise, and helping to cultivate a culture of reliability within the organization.
