Software Development Auckland 201–500 employees Founded 2007 Public Company

Serko operates a travel-and-expense platform spanning booking (GetThere, Zeno, Booking.com for Business), payments, and ML-driven workflows. The tech stack reveals a data-engineering-first posture: Java/.NET core systems sit atop a sophisticated analytics layer (Snowflake, Redshift, Synapse, Spark, Airflow, dbt) with active ML infrastructure (SageMaker, Vertex AI, MLflow, Kubeflow). Current hiring emphasis is engineering and data (25 of 40 open roles), with active work on agentic LLM features and data platform scaling—indicating a shift from traditional booking logic toward AI-native product surfaces.
