Senior Machine Learning Engineer, Risk AI/ML

Senior Machine Learning Engineer, Risk AI/ML Ready to be pushed beyond what you think you’re capable of? At Coinbase, our mission is to increase economic freedom in the world. It’s a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform — and with it, the future global financial system. We are looking for a Machine Learning Engineer to join our Risk AI/ML team. Your work will directly prevent fraud, account takeovers, and scams, while enabling future products like instant guest checkout and Coinbase Cards. This is a hands‑on technical role where you will leverage our cutting‑edge, self‑service ML platform to rapidly design, deploy, and iterate on the models that defend millions of users. Responsibilities Own a Critical Risk Domain: Take full technical ownership of a core problem space, such as Scams or Account Takeover. Design, build, and lead the strategy for all models in this domain. Architect and Design Systems: Lead the system design and architecture for new, complex risk detection models. This includes everything from feature pipeline design to model selection (e.g., GNNs, LSTMs, LLMs) and high‑performance serving. Drive the Technical Roadmap: Work with Product, Ops, and other stakeholders to translate ambiguous business needs into a clear technical roadmap. You will be the primary technical voice defining the "how." Mentor and Lead: Act as a technical leader and mentor for mid‑level and junior engineers on the team. Lead by example through code reviews, design docs, and coaching. Apply Advanced ML: Apply modern methodologies (deep learning, NLP, Graph Neural Networks, sequence modeling, and LLMs for NLP and conversational agents) to solve complex, crypto‑native challenges. Build Context‑Aware Risk Systems: Architect the adaptive logic that decides which friction (a quiz, an LLM agent, a human review) to apply to which user, balancing security with user experience. Qualifications 6‑8+ years of professional experience in software engineering and/or AI/ML, with experience deploying AI/ML systems into production. Proven track record of technical leadership , including designing and deploying large‑scale ML systems from scratch. Passion & Values: A commitment to building an open financial system and a strong desire to protect users from fraud and scams. You embody our core cultural values: add positive energy, communicate clearly, be curious, and be a builder. AI/ML Knowledge: Deep expertise in applied AI/ML techniques (Risk ML, deep learning, NLP, recommender systems, anomaly detection). Technical & Coding Skills: Expert‑level coding skills (Python) and deep experience with AI/ML frameworks (TensorFlow, PyTorch). Experience in building backend systems with a focus on data processing or analytics is a plus. Team Collaboration: Ability to work collaboratively on technical initiatives and contribute to impactful AI/ML solutions. Communication Skills: Strong communication skills, with the ability to convey technical concepts to both technical and non‑technical audiences. Nice to haves Master’s / Ph.D. in Computer Science, AI/ML, Data Science, or a related field. Familiarity with modern data and AI/ML infrastructure (Feature Stores like Tecton, Model Serving like RayServe, Apache Airflow, Spark, Kafka). Experience with Graph Neural Networks (GNNs) or Sequential Models (like LSTMs). Experience with LLMs (NLP, fine‑tuning, agentic systems) or Reinforcement Learning. Understanding of MLOps best practices, including monitoring and improving production models. Experience with data analysis and visualization tools.
