About The Position

SAIC is seeking a Software Solutions Engineer to support Space Systems Command's (SSC) Kronos Family of Systems (FoS) in advancing Operational Command and Control (C2) and Space Battle Management (BM). This role requires an experienced engineer who can work across application and enterprise perspectives, integrating new capabilities with legacy systems while modernizing the BMC3I software ecosystem. You will shape solutions across architecture, interfaces, data, infrastructure, cybersecurity, DevSecOps, and mission applications while preserving critical operations. This position is based in El Segundo, CA and supports the Horizon program within the Space C2 Program Management Office, working closely with the Space Systems Command's BMC3 Program Office.

Requirements

• Experienced engineer who can work across application and enterprise perspectives
• Integrate new capabilities with legacy systems
• Modernize the BMC3I software ecosystem
• Shape solutions across architecture, interfaces, data, infrastructure, cybersecurity, DevSecOps, and mission applications
• Preserve critical operations

Responsibilities

• Serve as a software engineering and integration focal point for BMC3I, aligning new development, commercial solutions, and modernization with existing Programs of Record, legacy systems, architecture, interfaces, data services, infrastructure, and operational requirements.
• Evaluate end-to-end software solutions to determine how new applications, services, data products, APIs, and platform capabilities integrate with or replace legacy components while preserving mission continuity and interoperability.
• Develop technical integration roadmaps defining modernization increments, legacy dependencies, interface transitions, data migrations, risks, decision points, and production transition activities.
• Support software architecture and design, including capability decomposition, service boundaries, APIs and interfaces, data flows, event-driven integration, cloud/platform services, deployment patterns, and distributed-system dependencies.
• Collaborate with developers, engineers, architects, cybersecurity and DevSecOps teams, testers, Product and Program Managers, vendors, operators, and legacy-system owners to resolve cross-system integration issues.
• Assess modernization opportunities to refactor, rehost, replatform, replace, or retire legacy components; reduce technical debt; and move toward modular, scalable, secure, and supportable architectures.
• Coordinate capabilities through development, CI/CD, integration, testing, cybersecurity assessment, deployment, production transition, and sustainment while maintaining configuration and release traceability.
• Assess integration readiness across applications, APIs, data models, messaging, infrastructure, identity, cybersecurity, observability, performance, resiliency, and mission-system interfaces.
• Plan data migration and interoperability between legacy and modernized systems, including schema mapping, transformation, interface compatibility, authoritative data sources, synchronization, and sequencing.
• Apply Agile, DevSecOps, and Software Acquisition Pathway practices to support iterative delivery, automated testing, CI/CD, platform modernization, and rapid operator feedback.
• Use Jira, Confluence, and related tools to maintain traceability of requirements, architecture decisions, interfaces, technical debt, defects, risks, dependencies, test findings, releases, and modernization status.
• Advise government leadership on architecture, modernization priorities, legacy transition, integration risks, sequencing, and technical tradeoffs across BMC3I.
