About the Role

This is a principal-level solution architecture role for a Java modernization expert who has led complex legacy system migrations, architected modern Spring Boot-based application platforms, and designed enterprise-grade identity management solutions.

Must-Have Skills

• 8+ years of solution architecture or senior engineering experience
• Expert-level Java / Spring Boot — microservices architecture, REST APIs, and enterprise application development
• Proven experience leading application modernization initiatives — migrating legacy systems to modern, cloud-native Java platforms
• Strong legacy system migration expertise — assessment, re-platforming, re-architecture, and cutover planning
• Hands-on experience designing and implementing identity management solutions — SSO, OAuth 2.0, OIDC, LDAP, Active Directory, or IAM platforms (Okta, Ping Identity, ForgeRock, or similar)
• Strong cloud platform experience — Azure, AWS, or GCP — for modernized application deployment
• Experience with CI/CD pipelines and DevOps practices — GitHub Actions, Azure DevOps, Jenkins, or similar
• Strong system design skills — scalability, reliability, security, and performance
• Excellent written and oral communication skills — able to present architecture decisions to technical and business stakeholders
• Ability to work on-site all 5 days in Omaha, NE

What You'll Do

• Own and lead end-to-end solution architecture for Java modernization and identity management initiatives across client engagements
• Assess existing legacy Java applications and systems — defining modernization roadmaps, re-platforming strategies, and migration sequencing plans
• Architect and oversee the development of modern Java / Spring Boot microservices platforms — designing for scalability, security, and cloud-native deployment
• Design and implement enterprise identity management solutions — SSO, OAuth 2.0, OIDC, MFA, and IAM platform integrations
• Lead technical design sessions, architecture reviews, and proof-of-concept development for modernization initiatives
• Define and enforce architecture standards, coding best practices, and security governance across client engagements
• Collaborate with business stakeholders, product owners, and engineering teams to align solutions with business and technical objectives
• Build and maintain detailed architecture documentation — solution designs, technical specifications, migration runbooks, and decision records
• Identify and mitigate technical risks across modernization and identity management workstreams
