Build Next - Generation Technology. Make a Meaningful Difference in Millions of American Lives.

Location: Woodlawn, Maryland | On-site, 5 days per week

The Opportunity

Imagine putting your software engineering expertise to work on technology that supports one of

America’s most important humanitarian missions—helping millions of Americans access essential services and benefits that can profoundly impact their lives.

We are seeking a Senior Java Developer with expertise in Artificial Intelligence, Large Language

Models (LLMs), and enterprise application architecture to help modernize and advance mission-

critical systems serving the American public.

This is an opportunity to work at the intersection of proven enterprise technologies and the rapidly evolving world of generative AI. You’ll help design and build scalable applications, integrate intelligent AI capabilities, and deliver secure, reliable solutions that improve how essential public services are delivered.

If you’re an experienced engineer who enjoys solving complex technical challenges, shaping

architecture, and putting emerging technologies to practical use, this is an opportunity to make yourexpertise count.

Why This Opportunity Stands Out

• Meaningful Impact: Contribute to technology that supports essential services for millions of

Americans.

• Innovative AI Engineering: Apply generative AI, LLMs, retrieval-augmented generation (RAG),

vector search, and agentic AI to real-world enterprise applications.

• Enterprise-Scale Challenges: Design high-performance, low-latency systems built for

demanding production environments.

• Technical Leadership: Influence architecture, improve engineering practices, and mentor

fellow developers.

• Modern Technology Stack: Work with Java, Spring Boot, microservices, REST APIs, AWS,

PostgreSQL, CI/CD, and emerging AI technologies.

• Mission-Driven Engineering: See how thoughtful architecture, secure development, and

reliable software can make a tangible difference in people’s lives. What You’ll Do

As a senior member of the engineering team, you will help shape the design, development, integration,and ongoing evolution of enterprise applications.

• Architect and develop scalable, cloud-native applications using Java, Spring Boot, RESTful APIs, and microservices.

• Integrate and operationally support LLM and agentic AI capabilities within enterprise

applications, including RAG, vector search, agent orchestration, evaluation, and guardrails.

• Design high-throughput, low-latency services capable of supporting substantial volumes of

concurrent requests.

• Develop and maintain RESTful and SOAP-based web services and enterprise integrations.

• Build reliable, secure, and maintainable solutions using established software design principles

and the Twelve-Factor App methodology.

(Basic Qualifications)

• 10+ years of experience with Java, Spring Boot, Gen AI, LLMs

• Extensive Design and Programming skills in Java and JEE technologies.

• Experience working on Agile projects and strong knowledge of Agile terminology and tools

including Agility.
