The selected candidate will operate within a cohesive, outcome-driven delivery team accountable for plugin modernization, application remediation, cloud deployment readiness, and production stabilization.
The Senior Appian Plugin Developer will serve as a hands-on technical contributor responsible for refactoring custom plugins, validating compatibility across the broader plugin inventory, and ensuring migration activities meet cloud, security, and quality standards. This role requires deep expertise in Appian plugin architecture, Java development, and cloud modernization practices.
Refactor custom Appian plugins to remove filesystem, database, and logging dependencies incompatible with Appian Cloud

Validate compatibility of custom and AppMarket plugins within Appian Cloud environments
Assess and remediate configuration or deployment gaps identified during plugin validation
Implement secure, centralized logging approaches aligned with cloud deployment standards
Package and deploy updated plugins across development, testing, and production environments
Support regression testing across dependent Appian applications impacted by plugin updates
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
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
Experience working in regulated environments (financial services or similar)
Comfort operating within high-accountability, milestone-driven engagements
7+ years of professional Java application development experience
3+ years of hands-on experience developing and maintaining custom Appian plugins
3+ years of experience modernizing or refactoring legacy application components for cloud environments
3+ years of experience designing secure integration patterns using RESTful APIs
3+ years of experience implementing and configuring modern logging frameworks (e.g., Log4j2, SLF4J)
3+ years of experience supporting deployments across development, testing, and production environments
3+ years of experience working within multi-team agile or hybrid delivery environments
Green Card holder or US Citizenship required
Must be able to obtain Public Trust Security clearance.
Experience supporting Appian Cloud migration initiatives
Demonstrated ability to assess technical debt and execute structured remediation plans
Appian Certified Developer (Senior or Lead preferred)
Experience supporting financial services or highly regulated enterprise clients
