Troubleshoot and resolve defects related to plugin behavior, integrations, or environmental differences
Collaborate with Appian Developers to remediate application objects and integrations impacted by cloud migration
Partner with DBAs to ensure plugin changes align with data migration and validation activities
Participate in structured migration governance processes, including technical documentation, status reporting, and risk tracking
Contribute to production cutover preparation, rollback validation planning, and post-migration stabilization
Document refactor strategies, compatibility findings, deployment steps, and definitions of done
Operate within a defined delivery cadence, maintaining accountability for milestones and technical quality
What We’re Looking For
Extensive hands-on experience developing custom Appian plugins (smart services, functions, integrations)
Strong expertise in Java development and plugin architecture within enterprise environments
Deep understanding of Appian Cloud constraints, supported APIs, and architectural best practices
Experience refactoring legacy codebases to remove filesystem access, unsupported database dependencies, and non-cloud-compliant logging
Strong debugging and troubleshooting skills in complex Appian environments
Experience validating and packaging plugins for multi-environment deployment
Ability to remain hands-on while working within a structured, governance-driven delivery model
Strong written and verbal communication skills, with the ability to clearly document technical findings and recommendations

Comfort operating within high-accountability, milestone-driven engagements
Required Skills:
