This is an exciting opportunity for a hands-on builder who excels at integrating Responsible AI principles into production-ready solutions. You will be a key technical contributor responsible for the entire lifecycle of our Responsible AI initiatives, from design and development to deployment and monitoring. You will work with a team of experts to build the scalable, high-performance, and trustworthy AI systems that are essential for our success.

Primary Responsibilities

• System Development: Develop and implement enterprise-scale Responsible AI systems and governance frameworks, ensuring they meet the ethical, performance, and security requirements for mission-critical applications.
• Framework Architecture: Contribute to the architecture and implementation of a centralized "Responsible AI Framework" to ensure compliance, manage model access, and provide a unified interface for governance and risk management.
• Monitoring and Auditing: Implement and manage robust monitoring systems to track model performance, fairness, bias, and ethical compliance, and to optimize the cost-effectiveness of AI systems in production.
• Strategic Collaboration: Work closely with principal engineers, data scientists, and systems architects to translate strategic designs into hardened, production-grade solutions that embed fairness, accountability, and transparency principles.
• Governance and Guardrails: Establish and maintain robust AI governance frameworks and guardrails to ensure data integrity, filter inputs/outputs, prevent bias, mitigate deployment risks, and protect against adversarial attacks.
• Best Practices: Apply and promote software engineering best practices, including robust version control, comprehensive automated testing, and mature CI/CD processes for AI systems.
• Continuous Learning: Stay current with industry trends in Responsible AI, Explainability (XAI), operational AI, and MLOps to continuously evolve the team's capabilities and technical implementation.

• Demonstrated programming proficiency in Python and hands-on experience with major ML libraries and frameworks (e.g., TensorFlow, PyTorch, Scikit-learn).
• Experience with software engineering best practices and tools, including version control, automated testing, and CI/CD pipelines.
• Solid understanding of the full machine learning lifecycle, from data preparation and model training to deployment and monitoring.
• A strong understanding of Responsible AI principles, ethical AI practices, and techniques for bias detection and mitigation.
• An understanding of cybersecurity principles as they apply to AI systems, including threat modeling and vulnerability assessment.

Preferred Qualifications

• Experience working within the national security, defense, or intelligence communities.
• Experience with MLOps platforms such as MLflow, Kubeflow, or AWS Sagemaker.
