The role also involves leveraging AI/ML-enabled development approaches, CI/CD practices, and modern API and application architectures.
You’ll collaborate across development, testing, integration, and modernization activities in a highly complex technology environment.
This is a remote full-time opportunity with occasional travel to Columbus, Ohio, and is contingent upon contract award.
Accountabilities:
- Translate and refactor legacy code into modern Java applications within a defined microservices architecture.
- Analyze and update the existing legacy code base, including COBOL, ASM, JCL, and Copybooks, to identify functional and non-functional code across the baseline.
- Apply AI/ML tools and development processes where appropriate to accelerate and improve legacy code translation.
- Optimize translated applications by applying microservices or other modular architectural approaches.
- Design and develop new software products and significant enhancements to existing applications.
- Address complex systems integration, compatibility, interoperability, and multi-platform challenges.
- Implement modernized code within pre-production environments to support development, testing, and integration activities.
- Support integration between modern UI/UX front ends, service layers, and relational databases.
- Develop and support both batch and real-time processing capabilities, including ingestion of flat files and modern file formats.
- Build and contribute to CI/CD pipelines, workflows, and development processes.
- Support Zero Trust, ICAM integration, and cloud-native capabilities.
- Apply Agile software development practices throughout design, development, testing, and deployment.
- Perform feasibility analysis for potential future initiatives and provide technical input to management.
- Contribute to legacy modernization, data migration, system analysis, and technical solution decomposition activities.
- Travel to Columbus, Ohio for on-site meetings approximately once per month, for up to three days per visit.
Requirements:
- At least 5 years of relevant professional experience in software development or a closely related technical field.
- Deep, demonstrated expertise in Java, which is the primary technical qualification for the role.

- Strong understanding of microservices architecture, modern application design, and software integration.
- Significant experience with Agile software development methodologies.
- Demonstrated experience working with highly complex IT environments, including legacy system upgrades, modernization, transition, data migration, or system analysis and design.
- Knowledge of COBOL is a significant advantage, particularly experience translating or modernizing mainframe applications.
- Prior experience converting mainframe systems to modern languages and architectures is highly desirable.
- AI/ML development or implementation experience is preferred.
- Experience with modern database design and software modernization within federal government or Department of Defense environments is highly valued.
- Ability to perform functional and technical solution decomposition to support effective analysis, architecture, and implementation.
- Oracle Certified Professional, Java SE certification, or equivalent certification is required.
- A bachelor's degree in Computer Science, Information Systems, Engineering, IT, or a related discipline is preferred; equivalent relevant experience may be considered.
- Must possess an IT-II Non-Critical Sensitive security clearance or Tier 3 (T3) clearance at the time of proposal submission.
- Strong analytical, problem-solving, communication, and collaboration skills.
