Staff Engineer at MongoDB

This role is designed for a seasoned technologist with at least 10 years of experience building mission-critical, high-concurrency systems. You are likely a senior leader or staff-level engineer who excels in C++, Java, or Go and has moved beyond just writing code to architecting complex distributed systems. Experience with low-level systems fundamentals—like multi-threading and performance profiling—is essential here. You will spearhead the Observability stack for a global database platform, managing massive scale (petabytes of logs and billions of metrics). Based in Dublin, this is a hybrid role that offers significant technical ownership and the chance to influence the long-term roadmap while mentoring a high-performing engineering team. **You might be a good fit if you:** * Have 10+ years of experience with distributed systems like VictoriaMetrics, Flink, or Kafka. * Enjoy "under the hood" engineering, such as database internals or performance tuning. * Are comfortable leading cross-company initiatives and advising product management on technical complexity. * Thrive in high-stakes environments where security, durability, and low latency are the top priorities.
