Customer Success Engineer

The Opportunity

Customer Success Engineer (CSE) will provide dedicated subject matter expertise in delivering Day Zero automation for tactical systems using NexTech Solutions' MANTLE Platform. This role is responsible for enabling the automated deployment, configuration, validation, troubleshooting, and sustainment of Android end-user devices (EUDs), network devices, datacenter infrastructure, and supporting application dependencies required for tactical data node systems.

This is a hybrid position based in Fayetteville, NC, combining remote work with on-site support for tactical systems at operational scale. The role serves as a key technical advisor to the customer and works closely with operational users, integrators, internal engineering teams, and government stakeholders to ensure successful adoption and operation of MANTLE-enabled automation workflows.

The ideal candidate combines strong Android EUD expertise with experience in infrastructure deployment, Linux, IP networking, and systems integration. The successful candidate will be comfortable diagnosing issues across the complete Android deployment path, from device provisioning and application installation to connectivity, certificates, permissions, and application behavior. Experience with Android development workflows, Gradle, Java, or Kotlin is a plus.
