Java Developer - IV

Title: Agentic AI Developer

Employment Type: Contract 12+ Months

Location: Irving, TX Or Alpharetta, GA (Onsite)

179537

Pay Range: $60/hr to $65/hr

We are seeking a skilled and forward-thinking Agentic AI Developer to design, build, and deploy autonomous AI agents and multi-agent systems. In this role, you will go beyond traditional static prompt engineering to create resilient, decision-making agentic workflows capable of planning, tool use, memory management, and autonomous execution to solve complex, multi-step real-world tasks.

You will collaborate closely with product managers, data engineers, and domain experts to take cutting-edge LLM agent architectures from research concepts into scalable, production-ready enterprise applications.

Key Responsibilities

Agent Design & Orchestration

• Architect and implement autonomous AI agents using modern frameworks (e.g., LangGraph, CrewAI, AutoGen, LlamaIndex, or custom orchestration loops).
• Design agent reasoning architectures, including ReAct loops, Plan-and-Solve patterns, Reflection/Self-Correction mechanisms, and hierarchical multi-agent structures.
• Construct robust tool-use pipelines enabling agents to seamlessly call external APIs, query databases, execute code, and interact with enterprise software.

System Architecture & Integration

• Integrate Long-Term Memory systems (vector databases, semantic search, key-value state stores) and Short-Term/Context Memory management strategies.
• Implement structured input/output parsing (Pydantic, JSON Schema) to guarantee reliable communication between model calls and execution environments.
• Build fallback mechanisms, human-in-the-loop (HITL) checkpoints, and deterministic guards around non-deterministic AI decisions.

Monitoring, Evaluation & Optimization

• Establish evaluation pipelines (using tools like Ragas, TruLens, or LangSmith) to benchmark agent accuracy, execution speed, trajectory quality, and tool failure rates.
• Monitor runtime performance, API usage costs, latency, and context-window token optimization across complex multi-step trajectories.
• Debug non-deterministic failures, looping behaviors, and hallucinations in multi-step agent execution paths.

Required Qualifications

• Education & Experience: Bachelor's or Master's degree in Computer Science, AI, Software Engineering, or equivalent practical experience with 1-2+ years focused on LLM/AI applications.
• Programming Skills: Expert-level proficiency in Python (TypeScript/JavaScript experience is a plus).
• Agent Frameworks: Demonstrated experience building with frameworks like LangGraph, CrewAI, Microsoft AutoGen, LlamaIndex Agents, or Semantic Kernel.
• API & Tool Integration: Proven track record building RESTful APIs, OpenAPI specifications, function calling architectures, and model tool definitions.
• Vector Databases & RAG: Hands-on experience with vector search engines (Pinecone, Qdrant, Milvus, Weaviate, or Chroma) and hybrid retriever architectures.
• Software Engineering Fundamentals: Strong background in asynchronous programming, microservices, Docker/Kubernetes, CI/CD, and unit/integration testing for non-deterministic AI systems.

Why Join Our Team

Our team is small, autonomous, and focused on delivering value quickly through AI, analytics, automation, and commonly available enterprise tools. We build practical solutions that help business partners work more effectively and make better decisions.

This role is critical to the foundation of our AI and agent development work. By improving data access, quality, mapping, and readiness, this position helps ensure that our agents, dashboards, and automation solutions are accurate, trusted, and useful.
