Duties & Responsibilities
• Lead the software development and integration lifecycle for resilient software and web applications, including requirements analysis, specification, architecture, design, development, integration, testing, deployment, maintenance, and sustainment.
• Work directly with senior leaders, technical stakeholders, and engineering teams to evaluate technical needs, define objectives, develop and prioritize backlogs, and deliver software capabilities at scale.
• Design, develop, integrate, and implement software solutions using modern DevSecOps practices, Service-Oriented Architecture (SOA), microservices, APIs, and other modular software approaches.
• Perform system and software design, development, integration, and implementation of proof-of-concept prototypes to evaluate emerging capabilities and rapidly transition successful solutions toward production use.
• Integrate software applications, web-based products, network operating environments, data services, and supporting systems to ensure interoperability and reliable end-to-end capability delivery.
• Apply software architecture, requirements-driven design, test-driven development, and behavior-driven development principles to improve software quality, resiliency, maintainability, and alignment with technical requirements.
• Analyze system workflows, data usage, software dependencies, interfaces, and technical problem areas to identify integration challenges and develop effective engineering solutions.
• Serve as a senior technical authority by providing recommendations to engineering and program leadership, mentoring junior engineers, reviewing technical approaches, and guiding teams through complex software development and integration challenges.
• Document and demonstrate technical solutions through system documentation, architecture diagrams, flowcharts, interface descriptions, specifications, standards, code comments, technical briefings, and other engineering artifacts.
Required knowledge, skills, abilities, education and experience:
• Extensive experience in software engineering, software systems integration, application development, systems engineering, or related technical disciplines supporting complex software environments.
• Strong understanding of software architecture, requirements-driven design, software integration, system interfaces, and the complete software development lifecycle.
• Experience designing, developing, integrating, testing, deploying, and sustaining resilient software applications, web applications, or distributed software systems.
• Experience developing software solutions using modern development practices, modular architectures, APIs, services, or microservices-based approaches.
• Experience supporting DevSecOps and Agile software development environments, including backlog management, iterative development, integration, testing, and rapid capability delivery.
• Experience performing system design, software development, integration, and implementation of prototypes or proof-of-concept capabilities.
• Experience analyzing system workflows, data flows, application interfaces, software dependencies, user requirements, and technical integration challenges.
• Demonstrated ability to provide senior technical leadership, mentor engineers, coordinate across multidisciplinary teams, and provide recommendations to technical and program leadership.
• Strong written and verbal communication skills with the ability to translate complex software and integration topics into clear recommendations for engineering, program, senior leadership, and technical audiences.

• Experience supporting government, defense, or other mission-focused software environments.
• Experience establishing or supporting production and development environments for operationally deployed software capabilities.
• Experience with Service-Oriented Architecture, microservices, containerized applications, APIs, distributed systems, and modern web application architectures.
• Experience with modern DevSecOps technologies and practices, including CI/CD pipelines, automated testing, containerization, orchestration, configuration management, and secure software delivery.
• Experience applying test-driven development, behavior-driven development, automated testing, software quality practices, or similar approaches within complex development environments.
• Experience integrating software across network operating environments, data services, infrastructure platforms, external applications, or other distributed system components.
• Experience supporting rapid innovation, prototyping, experimentation, demonstrations, testing, and transition of software capabilities into production environments.
• Experience developing and maintaining technical backlogs, translating technical requirements into executable engineering work, and coordinating priorities across multiple development or integration teams.
• Demonstrated ability to operate as a persistent and creative problem solver, rapidly learn emerging technologies and development practices, and guide technical teams through complex integration challenges.
