We are seeking a Senior Appian Plugin Developer to support a structured Appian Cloud migration engagement delivered through an Autonomous Delivery Pod model. This role is focused on modernizing custom Appian plugins and ensuring full compatibility with Appian Cloud architecture within a regulated enterprise environment.

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.

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

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
