Bachelor’s degree in Computer Science, Software Engineering, or related field (preferred).
Java development experience and enterprise frameworks.
Proficiency with GitHub and/or Bitbucket (branching strategies, pull request workflows, and peer review practices).
CI/CD engineering with Jenkins and/or GitHub Actions, including build/test/release automation and artifact promotion.
Static analysis and quality gating using SonarQube.
Containerization and orchestration using Docker, Kubernetes, and/or OpenShift.
Database change management using Liquibase.
Unit testing using JUnit with test automation embedded into delivery practices.
Strong documentation and design artifact skills (SADs, diagrams, integration plans) aligned to required governance templates and review cycles.
Proven Agile/SAFe delivery experience supporting sprint execution and PI planning.
Experience delivering in regulated environments requiring compliance documentation, security governance, and operational readiness practices

Nice To Haves

Cloud certifications (AWS / Azure / GCP)
Architecture certifications (TOGAF or equivalent enterprise architecture credentials)
Maven, Jacoco, JFrog Artifactory/Xray, ACR
Datadog for monitoring/observability
ServiceNow, Jira, Subject7, Postman/SoapUI

Responsibilities

Serve as the technical owner for assigned applications and services across the ITAC portfolio, providing implementation leadership for new development, enhancements, operations support, remediation, and modernization efforts.
Lead sprint-level technical execution within ITAC’s Agile/SAFe delivery model, ensuring engineering delivery meets sprint goals and program increment planning objectives.
Establish and enforce coding standards and architectural patterns (e.g., reusable components, API standards, dependency management, error handling, security-by-design).
Provide hands-on leadership across the implementation lifecycle: design, coding, debugging, refactoring, performance tuning, and build/deploy readiness.
Drive software engineering delivery for custom application development and enhancement, COTS configuration/customization and integration, and refactoring and modernization of legacy applications and services.
Ensure all technical solutions align to ITAC target architecture and enterprise architecture/security guidance; actively support EA approvals and governance expectations.
Author and maintain Solution Architecture Documents (SADs) and supporting artifacts using the ITAC Solution Architecture Template, including updates for major releases.
Participate in design and architecture reviews, coordinating with product owners, security stakeholders, DevOps/EOps, and configuration management teams.
Produce and maintain required technical design artifacts, including logical and deployment diagrams (including container/deployment topology where applicable), interface/integration specifications and dependency mapping, data flow diagrams and security boundary considerations, and integration and implementation plans, including rollback/back-out planning.
Ensure compliance with ITAC configuration management and release packaging standards (standard naming conventions, directory structures, versioning expectations, release-ready packaging).
Integrate delivery into ITAC CI/CD patterns and pipelines, including CloudBees Jenkins-based CI/CD pipelines and GitHub Actions workflows, where applicable.
Ensure DevSecOps best practices are implemented as standard controls, including automated builds, packaging, and artifact promotion; test automation embedded in pipelines (unit + regression + integration); and automated code quality and security scanning and gating.
Ensure secure SDLC practices are enforced across engineering work, incorporating security controls into design, implementation, and delivery.
Lead remediation for vulnerabilities and weaknesses discovered through ITAC security scanning and assessments, coordinating remediation plans and timelines with security stakeholders.
Drive modernization away from unsupported/EOL technologies and dependencies, ensuring systems remain within lifecycle support requirements.
Conduct deep technical code reviews focused on correctness, maintainability, performance, and security; architectural consistency and implementation standards; and testability and unit test coverage enforcement.
Establish quality gates and enforce maintainability standards through tools like SonarQube and pipeline-based controls.
Mentor developers on engineering best practices, enterprise Java patterns, CI/CD automation, secure coding standards, and container-native delivery.
Support and enforce Section 508 accessibility compliance, including ensuring required testing evidence and reporting support where needed.
Ensure required documentation, test evidence, and release artifacts are produced in alignment with ITAC delivery requirements and ORR readiness.
Ensure testing is embedded across the SDLC, including unit testing, integration testing, functional testing, regression testing, performance/load testing as applicable, and deployment validation and smoke testing.
Provide post-deployment validation (smoke testing, defect triage, hyper-care) and lead root cause analysis and corrective action for production issues.
Ensure stable releases through repeatable deployments and validation aligned to ITAC release governance.
Support production deployments and operational readiness activities, including deployment coordination with ITAC DevOps/EOps/CM teams, implementation planning, rollback/back-out readiness, and ORR stage gate support.
