Model Test and Measurement Engineer

ABOUT DEFCON AI RESILIENCE IN THE FACE OF DISRUPTION. DEFCON AI is an insights company that leverages artificial intelligence, mathematical optimization, data analytics, and software engineering for resilient optimization of complex systems. In today’s dynamically changing world, DEFCON AI’s technology aligns outcomes with operational goals, better decision making, and empowers customers to anticipate assess, and mitigate the impacts of disruptions. Be the independent voice that keeps the whole program honest — your evaluation is the standard everyone else is held to.   About the Role   You'll join the analytics and AI engineering team behind a system that genuinely matters: an AI-assisted platform that brings together records from dozens of disparate data sources, resolves them to the correct individual, highlights what analysts should review first, and provides transparent, explainable recommendations that users can trust. Operating within a secure government cloud environment, the platform tackles complex challenges in AI, data integration, and decision support where quality, trust, and accountability are mission-critical .   As a Model Test & Measurement Engineer, you'll own the evaluation framework that helps ensure those systems perform as intended. You'll build and maintain labeled ground truth datasets, design statistically sound audit and sampling methodologies, measure model performance across releases, and create the evidence packages that support deployment decisions. You'll independently validate both scoring and generative AI capabilities, helping the team understand not only whether a model works, but how confidently its outputs can be trusted.   This is a role with genuine influence. Your assessments will inform release decisions, drive improvement efforts, and provide the objective evidence customers rely on when evaluating system performance. You'll work closely with data scientists, AI engineers, and technical leadership while maintaining the independence needed to provide clear, defensible evaluations. You do not build the models you validate, and you do not approve thresholds or release authorization against your own evidence.   If you're energized by measurement, validation, and making complex AI systems more trustworthy, this is an opportunity to have an outsized impact on both the technology and the mission it supports.   This is a fully remote role with occasional travel to DEFCON AI headquarters, customer sites, and partner facilities as needed.   Key Responsibilities   Construct labeled ground truth for model evaluation   Design and run sampled audits   Gate releases against model version; maintain version inventory, evaluation records, and rollback triggers   Run drift and override review   Produce human-oversight and fairness / disparate-effect evidence   Maintain independence from the build roles: produce evaluation evidence, but do not build the models, approve thresholds, or authorize releases against that evidence   Measure workflow improvement: review time, throughput, backlog movement, and override and rework rates   Design evaluation-phase QC: sample selection that does not mix populations, the unit of review, and fair comparison when methods or searched sources differ   Define the measurement events other teams must emit, and confirm the review workspace emits workflow events from first use   Required Qualifications   5+ years with model validation as a named responsibility, not a side task   Direct experience with ground-truth construction and sampling design   Strong Python and SQL; comfort working independently from the teams whose models you evaluate   US Citizenship Required   Active US Secret clearance    Elevated personnel security requirements apply to portions of this work and are discussed during screening   Preferred Qualifications   Regulated-industry or government model-risk background   Experience with fairness / disparate-effect testing and human-oversight documentation   NIST AI RMF or comparable practice   Active Top Secret clearance   What Success Looks Like   Evaluation evidence a customer can rely on, independent of the teams that build the models   Releases gated against a clear version and evaluation record   Workflow metrics (review time, throughput, backlog, override/rework rates) that give the program an honest read on whether it's working   What We Offer   A fully remote, results-based environment   Competitive salary, bonus, and equity package   100% employer paid, comprehensive health insurance including medical, dental, and vision for you and your family   Unlimited PTO, with your manager's approval   Flexible work environment where you manage your work day   14 weeks of fully-paid parental leave   Salary Range: $150,000–$190,000. This represents the typical salary range for this position based on experience, skills, and other factors.   We’re an Equal Opportunity Employer: You’ll receive consideration for employment without regard to race, sex, color, religion, sexual orientation, gender identity, national origin, protected veteran status, or on the basis of disability.  Applicant Data Disclosure     By submitting an application, you acknowledge that Defcon AI uses third-party service providers to facilitate its recruitment and hiring processes.
