Everforth ECS, the federal segment of a $4B global organization, is seeking an AI Prompt Engineer to support the Cybersecurity and Infrastructure Security Agency's (CISA) Technical Engineering and Support Services (TESS) program. This role is based on-site in Arlington, VA.
You will design and govern AI-assisted workflows that accelerate the analysis of software vulnerability and risk data. Working with CISA-approved enterprise AI tools (primarily Microsoft Copilot), you will transform complex security datasets into actionable intelligence for federal cybersecurity operations.
Key Responsibilities:
- Craft, deploy, and refine structured system and user prompts using advanced role-play and constraint strategies to support software vulnerability analysis, CVE/CWE parsing, and threat risk summaries
- Systematically test model outputs across varied enterprise temperature and grounding parameters to eliminate hallucinations in risk scoring and threat summarization
- Document prompt patterns and maintain a centralized, version-controlled repository of reusable prompts with clear guidelines for technique application
- Enforce rigorous validation and reproducibility rubrics to benchmark prompt accuracy, consistency, and repeatability across software supply chain and vulnerability data feeds
- Translate manual CISA cybersecurity workflows into standardized AI-assisted templates to support technical delivery teams and capability leadership
Required Skills:
- Active Top Secret (TS) clearance with ability to obtain DHS/CISA Suitability
- 3+ years of professional experience working with AI/ML tools or large language models, with strong preference for candidates supporting federal, defense, or intelligence organizations
- Experience with CISA-approved AI toolsets (Enterprise Microsoft Copilot, M365 Copilot, GovCloud AI Environment)
- CompTIA Security+ or equivalent CompTIA certification meeting DoD 8140/8570 IAT Level II requirements
- Demonstrated expertise in generative AI prompt engineering techniques (chain-of-thought, few-shot framing, system instructions) and prompt evaluation/testing methodologies
- Proven capability to document, standardize, and scale repeatable technical practices for broader team adoption
Desired Skills:
- Bachelor's degree in Computer Science, Data Science, Information Technology, or related analytical field
- Familiarity with federal cybersecurity frameworks including NIST SP 800-53, CVE/CWE schemas, and CISA Known Exploited Vulnerabilities (KEV) catalog
