Applied Machine Learning Engineer

Job Description Job Description Must be a U.S. Citizen Secret Clearance preferred This position will to support mission-critical aerospace and defense programs. As an Applied Machine Learning Engineer, you will support informed decision-making around the application of machine learning and AI models in safety- and reliability-constrained systems. This role focuses on evaluating tradeoffs between retrieval-based approaches, fine-tuning, targeted training, and non-ML solutions. The position is onsite in Chandler, AZ and works closely with software, infrastructure, simulation, and GNC engineering teams. Requirements Bachelor's degree in Computer Science, Engineering, Mathematics, or related STEM field 3+ years of applied machine learning experience with production systems Demonstrated experience making technical tradeoff decisions around: RAG vs fine-tuning vs lightweight adaptation Model scope, training data selection, and evaluation Strong understanding of model failure modes, overfitting, and distribution shift Experience deploying ML in environments where correctness and reliability matter Ability to clearly communicate ML risks and limitations to non-ML engineers U.S. Citizenship Preferred Qualifications Experience with simulation, autonomous systems, aerospace, or defense programs Exposure to guidance, navigation, or control systems Experience working with hybrid ML + classical systems Familiarity with regulated or compliance-driven software environments Active or prior DoD security clearance Responsibilities Evaluate when machine learning should or should not be applied to engineering problems Advise teams on tradeoffs between RAG, fine-tuning, and targeted model training Support definition of heuristics for model selection, evaluation, and retraining Identify and mitigate ML failure modes in system and simulation contexts Collaborate with GNC, software, and infrastructure teams on safe ML integration Company Description We're Infinia Search.
