Lead Application Developer

Lead Application Developer

This position supports Revolutional's federal customer as part of an application transformation and modernization initiative.

This program is driving a large-scale transformation of systems into a data-centric, cloud-native ecosystem capable of supporting high-volume, near real-time data processing and advanced analytics. The work includes modernization of legacy applications, development of new cloud-native solutions, and implementation of DevSecOps and scaled Agile practices across the organization.

The core challenge: orchestrating complex, multi-contractor delivery while transforming both technology and operating models without disrupting mission-critical operations.

Position Description

As a Lead Application Developer at Revolutional, you will lead the design, development, modernization, and integration of enterprise applications supporting mission-critical federal operations.

This role requires a technically hands-on leader who can drive delivery across modern cloud-native environments while working closely with architects, engineers, product teams, and external partners. You will contribute directly to application development, modernization strategy, DevSecOps adoption, and system integration efforts.

You are expected to move beyond feature delivery—ensuring applications are scalable, secure, resilient, and aligned to evolving mission and compliance requirements.

Responsibilities

• Lead development and modernization of enterprise applications within a cloud-native ecosystem
• Refactor legacy and COTS applications into modular, microservices-based architectures using open-source technologies
• Design, develop, and integrate APIs, event-driven services, and messaging-based systems
• Develop secure, scalable, and highly available applications supporting high-volume and near real-time processing
• Contribute to AI/ML-enabled application workflows, including model integration and deployment support
• Build and maintain CI/CD pipelines supporting automated testing, deployment, and security validation
• Implement DevSecOps best practices, including secure SDLC, automated scanning, and compliance validation
• Support system-of-systems integration across multiple applications, contractors, and technical teams
• Ensure applications align with federal security and compliance requirements, including NIST, FedRAMP, FISMA, Zero Trust, MFA, and ATO support processes
• Design and support data ingestion, ETL pipelines, transformation, analytics, and dissemination capabilities
• Troubleshoot and resolve complex issues across application, infrastructure, integration, and data layers
• Lead code reviews, mentor developers, and enforce engineering standards and best practices
• Collaborate within Agile/Scrum and SAFe delivery environments to ensure consistent execution and delivery quality

Technical Environment
