Job Description

We are seeking a Senior Lead of Engineering to join the Observability team within MongoDB. This is an opportunity to join a team that is responsible for all Observability systems that support operational metrics, visualization, logs, traces, and alerts to monitor the performance and health of our customers' MongoDB deployments. We are looking for a senior leader that is results focused, with high standards, and experience in leading large teams of engineers (or leads) in designing, building and operating complex distributed systems at scale, with strict SLO on security, durability, availability and performance.

Tens of thousands of customers depend on our Observability stack to monitor their database clusters and to generate actionable alerts to safeguard critical workloads. As MongoDB Atlas and its supporting infrastructure continue to experience rapid growth, the demand for high-cardinality observability data for internal and external use cases means we need to continually innovate and scale our systems to the next level. For example, MongoDB Observability systems need to handle 10’s of billions of metrics time series, all whilst processing petabytes of logs, traces, and events.

Our team champions a strong culture of inclusivity, diversity, and collaboration. If you want to be a deeply technical leader on a collaborative team that applies low-level systems expertise to build the foundational infrastructure of a popular database, join us!

We are looking to speak to candidates who are based in Dublin for our hybrid working model.

What you’ll do

Lead and coach a large team of motivated individual contributors (up to 10) or leads who are eager to learn and grow

Contribute to the design, infrastructure and architecture of the high-volume ingestion systems your team develops

Work closely with product managers, program managers, and other engineering teams to specify, prioritize and deliver new features that delight our users, internally and externally
