As part of New Relic's engineering culture, observability is defined by Tim Krajcar as the ability to inspect a complex running system without pre-planned inspection points. This allows developers to focus on critical areas, such as business-critical processes like checkout, while also understanding the broader impact of upstream services that may cause problems. The term "observability" has become a popular synonym for monitoring in the industry, encompassing multiple disciplines and aiming for a holistic view of system performance. New Relic's Full-Stack Observability offers depth and breadth in data collection, enabling customers to make sense of their data and surface insights in usable ways. Key benefits include end-to-end tracing, incident response, and open-source agents that allow customers to send data from various tools. The company prioritizes team culture, engineering managers' autonomy, and the value of authenticity, which Tim Krajcar identifies with most. New Relic is currently hiring for cross-cutting engineering roles as it continues to reimagine its products in a full-stack model.
