Software Engineer 3, Atlas Growth 3
Confirmed on the employer's own hiring board on Oct 24, 2026. First seen by Alion on Jul 16, 2026. MongoDB scores B on the Alion truth index.
Atlas Growth is a cloud engineering group whose mission is to guide customers through their app development journey-from cluster configuration, data modeling and load testing, to running a production workload at scale. We use an in-house experiments platform which helps us validate our features quickly, releasing only the work that positively impacts our customers. Our engineers participate in cross-functional “squads” with product, design, analytics, and research focusing on a single metric (e.g. retention). Our engineering team is part of a larger Atlas Core Engineering org, building foundational elements of MongoDB’s developer data platform.
Atlas Growth 3 builds customer-facing features in Atlas and sits alongside other Growth engineering teams. Recent projects include an AI Chatbot for cluster creation, a recommendation system that offers tips for better database performance, and a pricing page designed to optimize conversion rates.
We are looking to speak to candidates who are based in Dublin for our hybrid working model.
