The Observability team is in charge of developing solutions that focus on application developers and engineers that run infrastructure and services supporting these applications. Elasticsearch is an efficient datastore for logs, metrics, and application traces, supporting the three pillars of observability. The Observability team builds and maintains solutions that make getting insights from this data turnkey and efficient, such as our APM, Infrastructure Monitoring, Logs, and Uptime solutions. When developing these solutions, we think about the problem end-to-end: how do we automatically collect data from common data sources, how do we store it efficiently in Elasticsearch, how do we present this information to the user, what actions do we take on the insights from the data? All of these aspects are important in bringing a turnkey solution to the market. 

As a Ruby Agent Engineer on the APM team, you will be part of a team developing a high quality, open source APM product aimed to help fellow Ruby developers instrument, debug, and monitor Ruby applications. As part of the APM Agents team, you’ll be deeply involved with the entire codebase of the Ruby APM Agent and collaborate on a daily basis with other Agent engineers in the team. You will take on responsibilities for new features, alignment with other agents, improving the resource and performance footprint of the agent and contribute to roadmap planning for the Ruby APM Agent. As a core contributor and maintainer of an open-source project, you will also be engaging with the open source community.

Besides close collaboration within the APM Agents team, you will also collaborate closely with the APM Server team when adding new features to the server API and with the UI team to ensure that we deliver the best possible experience for Ruby developers.

The team is diverse and distributed across the world, and collaborates on a daily basis over GitHub, Zoom, and Slack. Thus, the ability to work within a distributed team is critical.
