About the Role

SoFi's Senior Staff AI Engineer is a hands-on role within the independent risk organization, responsible for setting technical direction, driving execution, and ensuring the successful delivery of complex, production-level AI initiatives. This role will conceptualize, prototype, and implement AI-based solutions for risk management and compliance, working closely with the Director of Risk Analytics to solve challenging problems, mentor engineers, and connect technical innovation to business success.

Responsibilities

  • Define the long-term technical architecture and strategy for the AI platform, focusing on scalable agentic frameworks and LLM deployment patterns.
  • Architect and standardize the use of graph-based LLM orchestration using LangGraph for complex reasoning problems.
  • Develop persistent infrastructure for agentic state management to maintain context and reliability across distributed nodes.
  • Pioneer and institutionalize advanced parameter-efficient fine-tuning (PEFT) and compression techniques to optimize model performance and minimize costs.
  • Support the development of a unified model serving platform for custom-trained models, ensuring high-throughput, low-latency inference.
  • Define and enforce high standards for AI operationalization, including AI observability solutions and advanced tracing/testing frameworks.
  • Mentor senior and junior AI Engineers to elevate overall engineering quality.
  • Coordinate with cross-functional teams to distill requirements, define project roadmaps, and ensure timely project deliveries.
  • Stay up-to-date with the latest trends in GenAI, LLMs, and NLP, experimenting with new techniques to drive AI innovation.

Requirements

  • Bachelor’s or Master’s degree in Computer Science, Data Science, AI, Machine Learning, or a related field (PhD is a plus).
  • 8+ years of software development experience.
  • 3+ years of hands-on experience developing and deploying production-level AI applications.
  • Expert-level experience with LangGraph for LLM application orchestration.
  • Expert-level proficiency in developing agentic solutions with a portfolio demonstrating advanced use of planning, memory management, tool integration, and control flow.
  • Deep understanding of LLM architectures, prompt engineering, retrieval-augmented generation (RAG), and advanced text generation techniques.
  • Proven experience implementing parameter-efficient fine-tuning (PEFT) techniques (e.g., LoRA).
  • Deep expertise in building or extending inference engines (e.g., vLLM, NVIDIA Triton, or TGI) and managing Kubernetes/GPU orchestration.
  • Deep experience designing and institutionalizing AI observability solutions (e.g., LangSmith, Arize, Deepchecks) and advanced tracing/testing methodologies.
  • Experience with cloud platforms (AWS, Azure, or GCP) and containerization technologies (Docker, Kubernetes).
  • Expert level Python required.
  • React is strongly preferred.
  • Experience with large-scale data handling, including unstructured and structured data pipelines, with a preference for Snowflake and DynamoDB.
  • Experience developing and integrating AI-powered APIs and microservices architecture into banking applications.
  • Experience with vector databases and retrieval-augmented generation (RAG) techniques using systems like Elasticsearch, Pinecone, or FAISS.
  • Exceptional ability to communicate complex technical concepts, drive consensus among senior technical leaders, and influence organizational AI strategy.
  • Strong analytical and problem-solving skills with attention to detail.
  • Strong collaboration skills, with experience working in agile, cross-functional teams.
  • Familiarity with regulatory frameworks and ethical considerations in AI within the banking industry (e.g., GDPR, data privacy, model explainability) is a plus.
  • Experience in banking or financial services use cases such as conversational AI for customer service, intelligent document processing for loan applications, fraud detection, or risk analysis is a plus.
