Senior Software Systems Engineer- TS/SCI with Poly

architectures, integrate scalable software solutions, and ensure end-to-end technical alignment using modern engineering frameworks. If you’re a systems engineer with deep experience in software engineering environments, strong SOA expertise, and a passion for mission-first innovation-we want to hear from you.Key Responsibilities:

• Lead or contribute to Integrated Product Teams (IPTs) focused on designing and developing complex software-centric capabilities.
• Implement Service-Oriented Architecture (SOA) solutions and develop system/service views
• Perform Data Engineering of both structured and unstructured datasets.
• Participate in software design reviews, CCB meetings, and technical milestone events; coordinate cross-discipline resolutions.
• Develop and maintain interface definitions, control documents, and configuration baselines.
• Lead or support verification, validation, and test planning to ensure system deliverables meet functional and security requirements.
• Apply knowledge of Information Assurance (IA) technologies (e.g., authentication, access control, cryptography) to systems designs.
• Contribute to technical assessments, alternative analysis, and software risk management throughout the development lifecycle.
• Use modeling, simulation, and prototyping tools to reduce risk, validate system behavior, and improve engineering outcomes.
• Ensure documentation, systems artifacts, and change control processes are complete, traceable, and aligned with stakeholder needs.
• Design, develop, and maintain scalable, secure Java-based applications within distributed cloud architectures (AWS, Azure, or GCP).
• Serve as a bridge between software implementation and systems-level integration, ensuring functional alignment across services, APIs, and infrastructure.
• Lead the implementation of AI/ML capabilities in operational pipelines, coordinating with data science and platform teams.
• Conduct performance analysis and optimization across application tiers and system boundaries.
• Contribute to CI/CD pipeline design and infrastructure-as-code practices to support automated deployments and monitoring.
• Collaborate with systems engineers, DevOps, and solution architects to translate system requirements into working software components.
• Support full SDLC including requirements analysis, system-level documentation, and verification/testing.
• Provide mentoring and technical guidance to junior developers and systems engineers.

Primary Focus:

• 60% Hands-on Java development (Spring Boot, microservices)
• 40% Systems design, integration, and architecture alignment
• Operates at the intersection of software build-out and platform-wide reliability.
