IT Services and IT Consulting Herndon, Virginia 51–200 employees Founded 2008 Privately Held

Cliff Services is a mid-sized IT services firm anchored in data engineering (Python, PySpark, Spark, Airflow on AWS) and enterprise network architecture. The stack reveals a dual focus: cloud-native data pipelines (Redshift, Snowflake, Kinesis, Athena) paired with infrastructure modernization (Cisco, Kubernetes, ECS). Active hiring is engineering and data-heavy (24 of 32 roles in the last month), with seniority skewed toward senior and lead levels—typical of services firms scaling delivery capacity. Projects span data modernization, ML infrastructure governance, and legacy Cisco replacement, while pain points cluster around ML model governance, network migration, and cost efficiency at scale.
