The job, in the employer's words
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
