Original job description

Space Systems Integration (SSI) is a fast-growing engineering company that provides aerospace solutions to a variety of government and commercial customers. Our employees are forward-thinking, self-directed individuals who are committed to solving our customers’ technical challenges.

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

Role and Responsibilities include:

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.

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, API/interface design, data integration, testing, configuration management, and software lifecycle management.
Experience integrating new software into enterprise or mission systems containing legacy applications, shared services, data dependencies, external interfaces, and operational constraints.
Ability to analyze software at the system-of-systems level and translate mission and program requirements into practical integration and modernization approaches.
Proficiency with Microsoft Office, Jira, Confluence, and related collaboration and documentation 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, RESTful APIs, event architectures, infrastructure as code, automated CI/CD, observability, and secure software supply chains.
Knowledge of DoD software acquisition, including the Software Acquisition Pathway and DoDI 5000.87, with experience supporting rapid software delivery within a Program of Record.
Experience integrating commercial or non-traditional software into government architectures, legacy systems, and operational environments.
Demonstrated ability to lead cross-functional integration across software, systems engineering, cybersecurity, test, platform, operational, and government teams.
Experience evaluating technical debt, dependencies, sustainment, performance, scalability, resilience, cybersecurity, and lifecycle impacts in modernization strategies.
Strong communication skills with the ability to present complex architecture, modernization, integration, and technical tradeoffs to engineers and senior leaders.
