The Opportunity:

We are seeking a talented and highly motivated Software Engineer – Agentic AI to join a fast-growing, high-impact program focused on delivering next-generation AI-enabled capabilities. This is an opportunity to work at the forefront of cutting-edge AI technologies, helping design and build advanced autonomous agent systems that solve complex real-world problems in a rapidly evolving environment.

As part of our team, you will contribute to the architecture, development, and deployment of modern software solutions with a strong emphasis on Agentic AI, multi-agent collaboration, and scalable cloud-native systems. You will work alongside experienced engineers, architects, and technical leaders in an agile environment where innovation, rapid iteration, and technical excellence are highly valued.

The ideal candidate is passionate about emerging AI technologies, thrives in fast-moving engineering environments, and enjoys solving challenging technical problems across the full software development lifecycle. You will have the opportunity to influence system design, contribute to AI-driven product evolution, and help shape the future direction of autonomous intelligent systems.

Responsibilities:

• Design, develop, and maintain scalable software solutions supporting advanced Agentic AI capabilities
• Architect and implement autonomous agent systems leveraging agentic workflows, reasoning engines, and multi-agent collaboration
• Integrate AI agents with enterprise applications and distributed systems using APIs, standard protocols, and modern software architectures
• Manage the complete software development lifecycle from concept and design through deployment and sustainment
• Develop clean, maintainable, testable, and efficient code following modern software engineering best practices
• Build and maintain microservices and RESTful APIs supporting scalable and resilient applications
• Collaborate closely with engineers, architects, product managers, and mission stakeholders to rapidly deliver new capabilities
• Participate in Agile/Scrum activities including sprint planning, stand-ups, technical reviews, and retrospectives
• Develop and execute unit, integration, and system tests to ensure software quality and reliability
• Troubleshoot, optimize, and enhance system performance across cloud and on-premise environments
