Software Engineer, AI and Application Engineering

Onsite: Washington, DC

Mission Recruit is hiring a Software Engineer for our government client to design, build, and support modern, intelligent applications for federal retirement systems. This role blends full stack web application engineering with hands on AI and machine learning development. You will build the systems that serve federal employees and retirees, and the AI capabilities that make those systems smarter over time.

Core Technologies

• Design secure, scalable APIs using TypeScript, ASP.NET Core, or Java with Spring
• Integrate with enterprise systems via SOAP and REST APIs
• Optimize database performance with SQL Server and Entity Framework Core
• Design AI agents and LLM powered applications that automate retirement data workflows
• Build and maintain ML models for classification, prediction, and anomaly detection
• Integrate LLMs into production using prompt engineering, RAG, and agentic frameworks
• Develop data pipelines for large scale structured and unstructured data
• Apply explainable AI practices suited to a regulated, auditable environment
• Participate in Agile ceremonies, code reviews, and release planning

What You Bring

• BS or MS in Computer Science or a related field (required)

Requirements

• Must report onsite to one of the client offices in Macon, GA, Washington, DC, or Kansas City, KS
• Must complete a federal background investigation, which includes a conversation with your current supervisor

Who Thrives Here

The strongest candidates can reason about a React component and a retrieval pipeline in the same conversation. They read systems before rewriting them, evaluate models critically, and know that in a mission critical system, reliability, security, and explainability matter as much as capability.
