AI Agent Systems Software Engineer, Senior

The Opportunity:

As an AI software engineer, you've moved past building simple LLM wrappers and into the harder problem: building agents that interact with structured, deterministic systems, and produce results that are reliable enough to act on. You understand that the real challenge isn't getting a language model to generate text. It's getting an autonomous system to call the right tools in the right order, translate between natural language and formal representations, and know when it has made an error. We are building a platform where AI agents serve as the bridge between human intent and formal computational systems, and we need someone like you to design and build that bridge.

On this team, you'll own the AI agent layer that sits between operators and the platform's core reasoning and modeling capabilities. You'll design agents that can interpret loosely specified requests, discover relevant computational assets, translate requirements into structured inputs that formal systems can evaluate, and explain results back to users in language they can act on. When the underlying systems reject an input or return a counterexample, your agents need to localize the error, suggest corrections, and help users iterate quickly. You'll work with LLMs, tool-use frameworks, and retrieval systems, but always in service of a system where the final answers must be formally grounded, not probabilistically generated.

You'll join a small, elite team where everyone operates at the technical frontier. You'll be the person on the team who makes the system accessible, designing agents that let operators interact with formal reasoning and computational modeling through natural language rather than code. You'll build in a rapid development environment with AI-native tooling, measuring success by whether operators trust and have confidence in your agents.

Join us. The world can't wait.

You Have:

• 5+ years of experience designing and implementing software systems

• 2+ years of experience on applications involving large language models, autonomous agents, or natural language processing

• Experience building agentic systems that use tool calling, multi-step reasoning, or retrieval-augmented generation to interact with external APIs or structured data sources

• Experience with LLM orchestration frameworks such as LangGraph, LangChain, or agent-coordination tooling

• Ability to work across the boundary between probabilistic AI systems and deterministic software, ensuring that LLM outputs conform to the expectations of formal or structured downstream systems

• Ability to obtain a Secret clearance

• Bachelor's degree in computer science, artificial intelligence, or computational linguistics

Nice If You Have:

• Experience translating natural language specifications into formal or semi-formal representations such as constraint sets, typed schemas, or domain-specific intermediate languages

• Experience building human-in-the-loop AI workflows where the system proposes actions and a human approves, modifies, or rejects them

• Experience deploying or fine-tuning language models in secure or air-gapped environments for defense, intelligence, or national security customers

• TS/SCI clearance with a polygraph

• Master's degree in computer science or artificial intelligence preferred, Doctorate degree in computer science or artificial intelligence a plus

Clearance:

Applicants selected will be subject to a security investigation and may need to meet eligibility requirements for access to classified information.

Identity Statement

As part of the hiring process, we will ask you to complete an identity verification process that leverages advanced biometrics and artificial intelligence to ensure authenticity and protect against identity fraud. You are expected to be on camera during interviews and assessments. We reserve the right to take your picture to verify your identity and prevent fraud.

Candidate AI Usage Policy

AI is a part of our daily work at Booz Allen, and we are committed to the responsible and ethical use of AI tools. However, we want to ensure a fair candidate process based on your own skills and knowledge. As part of this commitment, the use of artificial intelligence (AI) or other tools to assist with responses during interviews (whether in-person or virtual) is prohibited unless permission is explicitly provided.

Work Model
Our people-first culture prioritizes the benefits of collaboration, whether it occurs in person or virtually. To support engagement and effective communication, employees working virtually are generally expected to have their cameras on during meetings.

• Remote: If this position is listed as remote, there may still be occasions when you are required to work in person at a Booz Allen or customer facility.

• Hybrid: If this position is listed as hybrid, you will be expected to work from a Booz Allen facility frequently, in alignment with leadership expectations and the needs of the role. You may also be required to work from or visit a customer facility.

• Onsite: If this position is listed as onsite, work will primarily be performed at a Booz Allen office or customer facility, where employees will collaborate directly with colleagues and customers as required by the role.

Commitment to Non-Discrimination

All qualified applicants will receive consideration for employment without regard to disability, status as a protected veteran or any other status protected by applicable federal, state, local, or international law.
