Full Job Description

Overview:

Agentic Engineer

Location: Tysons Corner, VA (Hybrid)

At Integral Federal, we invest in our people—equipping them with the tools, expertise, and culture of innovation needed to deliver measurable results. Committed to exceeding expectations and delivering mission impact, our team thrives on solving complex challenges, optimizing performance, and ensuring long-term success for our clients.

The Role: We are looking for a curious builder to join our team and develop AI Agents. You will design, build, and deploy autonomous agents and LLM-powered applications across AWS, Google Cloud, and Microsoft Azure.

We do not require a Master’s degree, a Bachelor’s degree, or any degree at all. We care about your understanding of modern AI architectures and your drive to repetitively solve problems. If you are the type of developer who loves tinkering with multi-agent workflows, experimenting with the Model Context Protocol (MCP), and testing the limits of new foundation models, you belong here.

Responsibilities:

Design and build autonomous AI agents using the latest large language models (LLMs) and orchestration frameworks.
Implement and leverage the Model Context Protocol (MCP) to seamlessly connect our AI models with external tools, APIs, and data sources.
Move beyond prototypes by building rigorous evaluation (Evals) pipelines and implementing LLM observability to ensure agents run reliably without hallucinating or getting stuck in infinite tool-calling loops.
Deploy AI solutions across multi-cloud environments, utilizing the best tools available on AWS, Google Cloud (GCP), and Microsoft Azure.
Translate complex, ambiguous problems into functional, robust, production-ready code.
Stay plugged into the bleeding edge of the AI landscape, bringing new tools, papers, and open-source projects to the team's attention.
Work closely with other engineers to securely and efficiently integrate agentic workflows into our existing infrastructure.

Qualifications:

What You Must Bring (Required):

Proof of Capability: Personal projects, GitHub repositories, or open-source contributions demonstrating your ability to build AI apps or agents. (Please include links in your application).
LLM & Agent Experience: Hands-on experience working directly with LLM APIs (OpenAI, Anthropic, Gemini, etc.) and building agentic loops (tool calling, memory management, reasoning).
Protocol Knowledge: Familiarity with or a strong desire to master the Model Context Protocol (MCP) for tool integration.
Cloud Fluency: Experience deploying applications or running experiments on at least one major cloud provider (AWS, GCP, or Azure) and a willingness to learn the others.
Builder’s Mindset: An insatiable curiosity, a high tolerance for ambiguity, and the grit to troubleshoot novel problems.
Ability to obtain a Secret clearance

Bonus Points (Preferred):

Experience fine-tuning models or working with local, open-weight models.
Experience testing models to create a baseline and identify drift
Experience building custom tools, robust RAG pipelines, or complex data ingestion pipelines from scratch.

Salary range: $90,000 - $175,000

The above salary range represents a general guideline. Integral Federal considers a number of factors when determining base salary offers, such as the scope and responsibilities of the position and the candidate's experience, education, skills, and current market conditions.

Depending on the position, employees may be eligible for overtime, shift differential, and/or discretionary bonuses in addition to base pay.

Company Overview:

Integral partners with federal defense, intelligence, and civilian leaders to tackle their most important challenges and deliver positive outcomes. Since our founding in 1998, we have helped clients leverage existing and emerging technologies to transform their enterprises, empower growth, drive innovation, and build sustainable success. The forward-leaning solutions we deliver are tailored to each mission with a focus on keeping our nation safe and secure.

Integral is headquartered in McLean, VA and serves clients throughout the country.

We offer a comprehensive total rewards package including paid parental leave and immediate vesting in our 401(k). Give us a try and become part of a curated group of professionals at Integral Federal!
