Full-time jobs in Arlington, TX

About the role

We are looking for a Software Integration Lead to own the integration of back-end subscriber and business support systems with E-Space's 5G Core network. This is a hands-on technical leadership role sitting at the boundary between the core network and the systems that provision, manage, and bill subscribers — SIM and eSIM provisioning, CRM, billing and charging, and device management. You will own the interface contracts, drive integration delivery, and ensure these systems interoperate correctly with core network functions end-to-end, spanning satellite and ground environments. As a member of our team, you will play a crucial role in driving our success. Our team members have a strong sense of dedication and responsibility; this includes a strong commitment to our mission to create an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet. This means that there will be times when extra hours, including nights and weekends, may be needed to meet critical deadlines and mission goals. In return, we offer a dynamic work environment with opportunities for professional growth and development and the chance to make a meaningful impact in a high-growth industry.

What you'll bring

• Bachelor's or Master's degree in Computer Science, Software Engineering, Electrical/Computer Engineering, or a related field.
• 12+ years of software engineering experience, with significant focus on BSS/OSS integration with mobile core networks.
• Strong understanding of 5G Core subscriber management and the interfaces that connect BSS/OSS systems to the core — authentication, session management, policy, and charging.
• Hands-on experience integrating SIM or eSIM provisioning infrastructure (SM-DP+, SM-SR, or equivalent) with mobile core subscriber management systems.
• Experience integrating CRM and billing platforms with telecom core networks: service provisioning APIs, online/offline charging interfaces, CDR delivery, and event-driven subscriber data updates.
• Experience with device management integration in a mobile or IoT context: policy enforcement, remote configuration, and status reporting over cellular.
• Strong API design and integration engineering skills: REST and event-driven interface specification, data model design, and integration test automation.
• Experience leading small software integration teams with clear API contract discipline and release tracking.
• Experience with eSIM and remote SIM provisioning in a satellite or IoT connectivity context.
• Background in MVNO BSS/OSS integration: multi-PLMN subscriber management, roaming data exchange, or MVNO billing stack integration.
• Familiarity with cloud-native core deployment and how containerised network functions affect BSS/OSS integration patterns.
• Experience in a startup or fast-paced R&D environment where integration scope expands rapidly.
