ESO

About The Position

ESO builds software that helps communities respond to emergencies and protect people and property. Our mission is to improve outcomes for responders and the public by delivering reliable, secure, and scalable products that support critical work—when minutes matter and failure isn’t an option. Our work is guided by ESO’s core values: Teamwork, Passion, Flexibility, and Integrity. We collaborate across teams to solve meaningful problems, bring care and energy to building products that serve first responders, adapt thoughtfully as our organization and technology evolve, and act with honesty and accountability—especially when decisions involve difficult tradeoffs. Our technology stack is Azure-based, featuring Angular-based web applications backed by .NET Core services, microservices hosted on Azure App Service and Azure Function Apps, Azure Service Bus for messaging, Azure Blob Storage for object storage, and Entity Framework Core with Azure SQL Database.
