Software Solutions Engineer Integrator

SSI is seeking a Software Solutions Engineer Integrator for a role in El Segundo, CA.

Role and Responsibilities include:

• Serve as the BMC3I software engineering and integration focal point, aligning new development, CSO-selected solutions, and modernization with Programs of Record, legacy systems, architecture, interfaces, data, infrastructure, and operational requirements.
• Evaluate end-to-end solutions to determine how applications, services, data products, APIs, and platforms integrate with or replace legacy components while preserving mission continuity and interoperability.
• Develop technical integration roadmaps covering modernization increments, legacy dependencies, interface transitions, risks, decision points, entrance/exit criteria, and production transition actions.
• Support software architecture and design across service boundaries, APIs/interfaces, data flows, cloud/platform services, deployment patterns, and legacy-to-modern data migration and interoperability.
• Collaborate with developers, architects, cybersecurity/DevSecOps teams, testers, Product and Program Managers, acquisition professionals, vendors, operators, and receiving programs to resolve integration issues and transition capabilities into operations.
• Assess 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 assessment, prototyping, development, CI/CD, integration, testing, cybersecurity, deployment, production transition, and sustainment while maintaining configuration, release, risk, and transition traceability.
• Assess integration readiness across applications, APIs, data, messaging, infrastructure, identity, cybersecurity, performance, resiliency, and mission-system interfaces, including demonstrations or operational evaluations as needed.
• Apply Agile, DevSecOps, and Software Acquisition Pathway practices to support iterative delivery, automated testing, modernization, and rapid operator feedback.
• Advise government leadership on architecture, modernization priorities, commercial-solution readiness, legacy transition, integration risks, sequencing, and technical tradeoffs.

  Support transition planning with receiving Programs of Record and follow-on acquisition activities, addressing architecture/interfaces, infrastructure, cybersecurity/accreditation, sustainment, production, contracting, funding, technical evaluations, SOWs, and transition agreements.

Required Qualifications

• Bachelor's degree with 14+ years, Master's with 12+ years, or PhD with 9+ years of relevant experience in software engineering, computer science, systems engineering, architecture, integration, or related DoD mission systems.
• Strong knowledge of software engineering, architecture, systems integration, APIs, data integration, testing, configuration management, and software lifecycle practices.
• Experience integrating software into mission or enterprise systems with legacy applications, shared services, data dependencies, external interfaces, and operational constraints.
• Ability to analyze software at the system-of-systems level and translate mission requirements into practical integration and modernization approaches.
• Proficiency with Microsoft Office, Jira, Confluence, and related collaboration tools.
• Active TS clearance with in-scope T5/SSBI is required, along with SCI eligibility and participation in Continuous Evaluation.
• Must meet all requirements for SCI and SAP access and be willing to undergo a polygraph examination.
• Travel is 25%.

Preferred Qualifications

• Experience modernizing legacy DoD software through refactoring, rehosting, re-platforming, cloud migration, API enablement, data migration, service decomposition, or retirement.
• Experience with cloud platforms, containers/Kubernetes, microservices, APIs, event architectures, infrastructure as code, CI/CD, observability, and secure software supply chains.
• Knowledge of DoD software acquisition, including DoDI 5000.87 and the Software Acquisition Pathway, with experience supporting CSOs, OTAs, rapid prototyping, or similar approaches.
• Experience transitioning commercial or non-traditional software from prototype into government architectures, production environments, and sustained operations.
• Experience evaluating technical debt, dependencies, sustainment, performance, resilience, cybersecurity, and lifecycle impacts during modernization.
• Strong communication skills with the ability to present architecture, integration, modernization, and technical tradeoffs to engineers and senior leaders.
