If you thrive at the intersection of deep technical work and strategic influence, this role offers the chance to shape the future of a major mission-critical system.

Your Next Career Challenge

We’re seeking a Chief Architect to lead the engineering and design strategy for containerizing software components within the Missile Warning system. Reporting directly to the Program Manager, you will guide a multidisciplinary systems engineering team—spanning systems, software, and test engineering—responsible for the SysML and UML models that enable migration of legacy code into a modern, containerized environment.

This is a high‑impact technical leadership role where you will define the architectural vision, drive modernization strategy, and mentor teams through a complex, multi‑phase transformation.

Key Responsibilities:

• Lead and mentor a team of system engineers, software engineers, test engineers, and supporting roles
• Ensure successful contract execution and on‑schedule delivery
• Validate test procedures and plans to ensure alignment with customer requirements
• Drive the conversion of a non‑containerized environment into a fully containerized architecture (primary focus)
• Interpret and guide SysML and UML modeling to support software enhancement delivery
• Define and communicate a clear migration vision and architectural strategy that balances mission needs, technical constraints, and stakeholder priorities
• Recommend target architectures and phased migration strategies for transitioning from a monolithic system‑of‑systems to a modular, container‑based environment
• Design service decomposition patterns and define appropriate service boundaries
• Translate strategy into a pragmatic migration roadmap with milestones, success criteria, and risk‑reduction steps
• Oversee migration patterns, anti‑corruption layers, and incremental cutover approaches while assessing downstream impacts
• Mentor engineering teams on containerization best practices and integration testing strategies
• Lead development and governance of canonical system models (logical, behavioral, allocation views) to support contract‑first API and event schema design
• Define verification and validation strategies using model‑based test generation, simulation, and scenario‑driven validation for phased migration
• Utilize requirements management and traceability tools (IBM DOORS/DOORS Next, Jama, Polarion) and ensure linkage to MBSE artifacts

Basic Qualifications

• Bachelor’s degree in computer science, software engineering, or related discipline with 12+ years of relevant experience (Additional experience, training, or certifications may substitute for degree)
• US Citizen; currently possessing an active DoD Secret clearance.
• Understanding of C++/Java in containerized environments
• Experience with requirements management and traceability tools (IBM DOORS/DOORS Next, Jama, Polarion)
• Demonstrated experience decomposing or modernizing monolithic applications through analysis, planning, and phased migration
• Strong knowledge of container technologies (e.g., Docker) and orchestration platforms (e.g., Kubernetes)
• Experience designing APIs and contract‑first integration patterns (REST, WSDL‑first SOAP, gRPC, event‑driven messaging)
• Ability to produce migration roadmaps with cost/benefit analysis, risk assessment, and measurable success criteria

​Preferred Qualifications

• Master’s degree in computer science, software engineering, or related discipline with 10+ years of relevant experience.
• Excellent written and verbal communication skills
• Understanding of missile defense systems
• Experience with stateful workloads on Kubernetes (operators, StatefulSets, CSI drivers, backup/restore strategies)
• Deep familiarity with data migration strategies (strangler fig, anti‑corruption layers, CQRS, event sourcing, change‑data‑capture)
• Proven track record mentoring engineering teams and building platform capabilities
• Experience translating JMS message formats into named streams for record publication
• Hands‑on experience with model repositories and collaboration platforms (Teamwork Server, Cameo Collaborator, etc.), including model versioning and branching strategies
