Remote Principal Rf Engineer Jobs in Colorado (NOW HIRING)

About the role
NSPM-11 directs the national security enterprise to adopt AI fast and assure it across the full stack, down to the data pipeline. That is our home field. 

We are hiring a Principal AI Engineer, AI Security to build agentic and mission AI on the Bluestaq platform. You will prove it secure and resilient from design through deployment. 

This is a senior individual-contributor role with a player-coach path. You will deliver hands-on now and stand up and lead a small AI team as the work grows. You will be the AI technical authority across the full lifecycle, from shaping bids to assuring what we deliver. 

What you'll do 

• Serve as the AI Security technical authority on captures and bids. Translate mission-owner AI and AI-security requirements into solutions that win. Build credibility with technical buyers across the IC, DoD, and partners. 
• Own AI-assurance/security roadmap for the platform, spanning model security, runtime protection, and threat modeling for AI built on Bluestaq data. Partner with engineering to embed assurance by design. 
• Design and assure AI for the environments mission owners operate in, including disconnected, classified, and air-gapped settings where assurance cannot depend on continuous cloud connectivity. 
• Threat-model AI systems against the attacks that matter at this level: adversarial inputs, model extraction and distillation, data and supply-chain poisoning, and agentic or tool-use abuse. 
• Establish and carry the external voice on secure AI for national security through talks, writing, and demonstrated technical work. 
• Ensure delivered AI meets the assurance, TEVV, and supply-chain standards mission owners depend on, so trust drives expansion and renewal. 
• Connect AI-security work into Bluestaq's broader AI platform, so evaluation frameworks, model registries, and pipelines serve the whole program instead of a security-only silo. 
• Stay ahead of AI/ML advances and bring in the ones that offer real advantage here, not the ones that just make headlines. 
• Coach mission owners and non-technical stakeholders on what AI can realistically do, so expectations match reality before a program commits. 
• Spot gaps in Bluestaq's AI tooling, skills, or process before they become blockers, and drive the proposals that close them. 
• Hire and lead a small AI team as the pipeline grows. 

Required qualifications 

• Five or more years across AI security architecture, AI/ML engineering, or a closely related combination, with demonstrated specialization at the intersection of the two. 
• Hands-on experience securing modern AI systems: LLMs, retrieval-augmented generation, and agentic or tool-using architectures, including MCP-style integrations. 
• Working command of the AI threat landscape and practical countermeasures, including where those countermeasures are weak and you compensate with architecture. 
• Cloud security depth, AWS preferred, including identity and workload isolation for model and inference traffic, preferably supporting large-scale Intelligence Community programs. 
• Ability to translate AI risk so a customer accreditor, a security auditor, and an engineer each understand it in their own terms. 
• The seniority to own a domain, set standards, and influence engineering decisions without direct authority. 
• U.S. citizenship and the ability to obtain and maintain a U.S. government security clearance. 

Preferred qualifications 

• Active TS/SCI. 
• A public technical record in AI security: research, conference talks, open tooling, red-team writeups, or sustained content. We value the thinking shown, not just the resume. 
• Experience delivering and assuring AI in regulated or government environments. 
• Familiarity with the federal AI assurance landscape, including NIST AI RMF, TEVV, and the NSPM-11 mandate. 
• Secure AI/ML supply-chain experience: model and dataset provenance, third-party model risk, and the equivalent of an SBOM for models. 
• Experience standing up an AI or AI-security capability from zero and growing a team into it. 

Education
Bachelor's degree in Computer Science, Cybersecurity, or a related field, or equivalent experience. Advanced degree preferred. 

Required Location & Travel
This position remote, open to candidates based in Colorado or Virginia, with up to 12 trips per year to customer, partner, or government sites, including secure facilities.
