Site Reliability Engineer, Customer Security

About the role

Are you passionate about creating and maintaining scalable, reliable, and secure cloud infrastructure? As a Site Reliability Engineer at Coalition, you'll play a pivotal role in ensuring the performance, availability, and efficiency of our cloud-based systems. Working closely with cross-functional teams, you’ll design, implement, and manage robust cloud solutions that drive our mission to protect the unprotected.

This role offers the opportunity to work on impactful projects such as automating infrastructure, building developer-friendly platforms and paved roads, optimizing cloud resources, improving system observability, and driving operational excellence across the organization. You will also participate in a low-volume on-call rotation to ensure our systems remain highly reliable and available.

In this role, you'll focus on isolating, trapping, and responding to the inevitability of system failure, developing strategies for continuous monitoring and analysis to minimize downtime and reduce the need for manual intervention. Our core platform is primarily built in Python, with some services written in Java and Go. We take a pragmatic approach to technology, using the right tools for the job and designing systems to scale and evolve as we grow.

This role is a great fit for software engineers looking to transition into SRE or for experienced SREs eager to work in a dynamic environment solving challenging technical problems. If you thrive on solving complex problems, working with cutting-edge technologies, and making systems resilient, we’d love to hear from you!

This is a remote position that can be based in the United States or Canada.
