Pan-European alarm and home-security provider with 650K+ customers across 8 countries
Sector Alarm operates a large-scale alarm and monitoring business across eight European markets (Norway, Sweden, Finland, Ireland, Spain, France, Italy, Portugal) with over 650,000 active customers and a 95% satisfaction rating. The tech stack is heavily Azure-dependent (.NET, C#, React, AKS, Data Factory, Databricks) with emerging data-platform work (Spark, Delta Lake, MLflow), and hiring is skewed toward sales and junior roles — a pattern typical of customer-acquisition-focused security businesses managing rapid geographic expansion. Recent projects center on cloud migration, IoT device backends, and identity infrastructure, while pain points cluster around market entry, churn, and scalability.
