AI/ML Engineer

Requirements We are looking for an AI/ML Engineer who is growing strong technical depth in machine learning, experimentation, and analytical problem solving, with an interest in applying those skills to trust, safety, and risk challenges across Chime 1–2 years of experience in applied data science or AI/ML engineering, including relevant internship, academic, or project experience Working knowledge of machine learning fundamentals, including feature development, model training, validation, tuning, and evaluation Familiarity with cloud platforms, preferably AWS, orchestration tools, and version control Familiarity with offline model evaluation, experimentation, and model performance tradeoffs Ability to communicate analyses and model findings clearly, clarify requirements, and collaborate effectively with technical and non-technical partners

• Desirable) Exposure to production ML workflows, including inference, monitoring, retraining, orchestration, model deployment
• Desirable) Experience using AI‑assisted development tools such as Cursor, Claude Code, or similar tools
• Desirable) Exposure to deep learning methods, such as embeddings, sequence models, representation learning, or behavioral modeling

What the job involves Chime’s AI/ML Trust & Safety team is building models, insights, and decisioning systems that help protect millions of members while enabling safe, reliable financial progress You’ll contribute to end-to-end model development, analysis, and production‑facing decision systems with guidance from senior team members. Your work will help improve how Chime detects risk, understands member behavior, evaluates tradeoffs, and scales trustworthy member experiences This role is a strong opportunity to build deeper expertise in applied ML, risk systems, experimentation, generative AI, sequence models, and cross‑functional product impact in a high‑scale environment Contribute to the design and implementation of training pipeline components for AI/ML models that support Chime’s risk decisioning systems Develop, test, and iterate on model features within clear requirements and with support from senior team members Support offline model evaluation and contribute to online experiment analysis to understand performance, tradeoffs, and member impact Write modular, testable, and maintainable code following engineering best practices Collaborate with Product Managers, Engineers, and Risk teams to translate model findings into clear recommendations and measurable member impact Contribute to production‑facing model workflows, including model training, tuning, inference, and monitoring Contribute to projects that apply modern AI/ML methods, such as generative AI, sequence models, and automation workflows, to improve Risk decisioning #J-18808-Ljbffr Chime
