Job description

Ready to make connectivity from space universally accessible, secure and actionable? Then you've come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.

We're intentional, we're unapologetically curious and we're 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

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.

What you will do:
  • Own the integration architecture and delivery for back-end systems that interface directly with the 5G Core: SIM/eSIM provisioning, CRM, billing and online/offline charging, and device management.
  • Define and implement the integration between SIM and eSIM provisioning infrastructure and core subscriber management - including subscriber profile delivery, remote SIM provisioning workflows, and profile lifecycle management across satellite and ground.
  • Design and own the interface between CRM and the core network: subscriber record synchronisation, service entitlement and quota management, and real-time event delivery for customer-facing workflows.
  • Lead integration of the billing and charging stack with the core charging interfaces - CDR generation and delivery, online charging authorization flows, and reconciliation between core charging events and BSS billing records.
  • Integrate device management capabilities with core network functions, including device policy enforcement, configuration delivery, and status signalling across the satellite link.
  • Define interface contracts (API specifications, data models, event schemas) at each BSS/OSS-to-core boundary; maintain them as the engineering source of truth shared across core software and back-end platform teams.
  • Build and maintain integration test harnesses for each BSS/OSS-to-core interface; drive automation and define acceptance criteria for every interface at each release milestone.
  • Own defect triage and root-cause analysis for integration failures at BSS/OSS-to-core boundaries; coordinate resolution across core software and back-end platform engineering teams.
  • Lead and mentor a small integration engineering team (2-4 engineers); set delivery cadence and engineering quality standards.
What you bring to this role:
  • 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.
Bonus points for the following:
  • 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.
  • Prior work with government or defence connectivity platforms with BSS/OSS integration requirements.
$180,000 - $220,000 a year

This is a full time, exempt position, based out of our Saratoga, CA office. 
 
The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience. 
 
We are redefining how satellites are designed, manufactured and used-so we're looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that's your experience - then we'll be immediately wow-ed.
 
E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.  The Company is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.
