Software Development Downtown Redwood City, California 201–500 employees Founded 2000 Privately Held

Clickatell operates a chat commerce platform built on Python, Java, and cloud infrastructure (AWS, Azure, GCP) with messaging APIs (WhatsApp, SMS) at the core. The stack reveals a mature data layer (Kafka, Spark, Hadoop, PostgreSQL, Redis) supporting high-volume transactional workloads—a critical requirement given their pain-point focus on scalable architectures and transactional volume. Current hiring is tilted toward engineering and research roles with a seniority mix skewed senior/director, suggesting product innovation and infrastructure scaling rather than headcount expansion.
