About The Position

Titan is hiring! We are seeking a highly qualified Data Scientist / Software Developer to support mission-critical, AI-based services for a government client operating in a secure, classified environment. Consider this exciting opportunity to work at the forefront of applied AI and knowledge systems, directly impacting national-level initiatives. In this role, you will play a pivotal role in designing, managing, and evolving AI-driven solutions that enable users to leverage private and sensitive content effectively. If you bring extensive experience in knowledge and ontology management, deep understanding of ontology standards and tools, and the security credentials to operate in a highly restricted environment, we'd like to hear from you!

This position will serve as a technical bridge between advanced AI research and production engineering, tasked with developing and evaluating LLM-powered services and semantic knowledge systems for the Compendia Data Platform to meet critical mission requirements.

This is a hands-on role to build production-grade AI and data capabilities and evaluation frameworks and metrics, in support of the 2026 roadmap and parallel customer commitments.

Requirements

• 2+ years of strong Python skills and experience delivering production software (APIs/services), including testing and version control.
• 2+ years of experience with NLP and/or modern LLM workflows (prompting, retrieval, fine-tuning/adaptation, and/or tool/agent integration) and an understanding of evaluation considerations.
• 2+ years of experience designing experiments and quantitative evaluation (metrics, baselines, error analysis) and communicating results to technical and non-technical stakeholders.
• U.S. Citizenship and ability to obtain a DOE "Q" or DoD Top Secret clearance.

Nice To Haves

• Familiarity with semantic technologies (knowledge graphs, ontologies, reasoning/inference, schema/ontology management) or a strong interest in learning quickly.
• Comfort working in a modern development environment (e.g., VS Code), collaborating in a team, and driving consistent progress across parallel priorities.

Responsibilities

• Design, build, and deploy AI-enabled services for the Compendia Data Platform (CDP), including LLM-based NLP capabilities and interoperable (agentic) components.
• Develop and maintain evaluation frameworks for LLM - ontology/knowledge base integration, including quantitative metrics, baselines, error analysis, and reporting to support defensible architecture decisions.
• Support ontology lifecycle management (modeling, inference, validation, and lifecycle workflows) as the ontology module matures from MVP to GA.
• Partner with product and engineering to improve platform stability, performance, and scalability for CDP v1.8 and beyond.
• Contribute to proofs of concept (PoCs), demos, and mission-aligned analytics workflows while sustaining LANL delivery commitments.
• Stay current on relevant research and emerging patterns for semantic engineering, LLM evaluation, and production AI systems; translate findings into implementable, testable solutions.
• Contribute to a high-performing team culture by delivering mission-aligned analytics and software tools that ensure high customer satisfaction and meet strict delivery commitments.
