About the Job

Requirements

  • Must have earned a Master's degree in Computer Science, Machine Learning, Data Science, Artificial Intelligence, Computer Engineering, Software Engineering, or another technical field before the full-time start date.
  • Knowledge of Python and foundational data processing technologies.
  • Foundational understanding of computer science concepts, including data structures, algorithms, object-oriented programming, debugging, testing, and problem solving.
  • Foundational understanding of machine learning concepts such as supervised learning, unsupervised learning, model training, evaluation, feature engineering, and experimentation.
  • Introductory understanding of modern AI systems, including large language model APIs, prompt-based interactions, retrieval patterns, AI-powered tools, or generative AI applications.
  • Ability to support AI/ML development, testing, documentation, integration, or data pipeline activities under guidance.
  • Awareness of responsible AI expectations, including reliability, safety, governance, security, privacy, compliance, and appropriate escalation when work is unclear or outside standard guidance.
  • Strong communication, collaboration, and documentation skills, and learning agility to work effectively across technical and non-technical teams.
  • Employment eligibility to work with American Express in the United States is required; the company will not pursue visa sponsorship for these positions.

Responsibilities

  • Support the development, testing, and integration of AI/ML models, large language model integrations, intelligent services, or data retrieval pipelines under guidance.
  • Assist with data collection, preprocessing, transformation, and validation to support model training, testing, evaluation, and implementation.
  • Contribute to debugging and improving AI-enabled solutions to strengthen performance, reliability, explainability, maintainability, and quality.
  • Support AI capabilities such as model training workflows, inference endpoints, prompt-based interactions, evaluation routines, retrieval patterns, AI agents, or agentic workflows.
  • Collaborate with engineering, product, data, risk, security, and business partners to implement AI-driven solutions aligned to business requirements.
  • Document model parameters, prompts, assumptions, data pipelines, integrations, and technical decisions to support reproducibility and knowledge sharing.
  • Participate in Agile development practices, including sprint planning, stand-ups, demos, retrospectives, code reviews, and team ceremonies.
  • Assist in ensuring AI systems and AI-enabled features align with enterprise expectations for reliability, safety, governance, security, compliance, and appropriate escalation.

Desired Qualifications

  • Master's degree candidates with an expected graduation date between December 2026 and June 2027.
  • Experience through academic coursework, research, projects, open-source contributions, internships, hackathons, or extracurricular activities using Python, R, Java, JavaScript, or similar technologies.
  • Interest in machine learning, generative AI, natural language processing, intelligent automation, data engineering, agentic AI, or AI-enabled software development.
  • Familiarity with natural language processing techniques and model concepts such as fuzzy matching, embeddings, BERT, transformers, large language models, or other modern language models.
  • Exposure to large language model APIs or similar AI models, including prompt engineering, prompt evaluation, tools, function calling, retrieval patterns, or agent workflow concepts.
  • Experience or coursework involving machine learning algorithms and applying them to practical or real-world problems.
  • Familiarity with APIs, data pipelines, extract-transform-load processes, cloud environments, containerized development, model deployment patterns, or monitoring.
  • Awareness of continuous integration and continuous delivery, version control, testing, code reviews, Agile development, and collaborative software engineering workflows.
  • Exposure to version control systems such as Git and collaborative software development workflows.
  • Curiosity about AI-powered developer tools, responsible AI practices, governance, security, model documentation, and enterprise-scale delivery.

About the Company

American Express

Issues credit cards and runs a payment network

American Express issues credit and pay-in-full charge cards to consumers and businesses, and unlike most card issuers it also runs the payment network its cards use. Its Travelers Cheque, launched in 1891, made carrying money abroad safer, and in 1959 it became the first major issuer of plastic cards. Cardholders earn points toward flights and hotels plus perks such as airport lounges, while companies use its corporate cards for employee travel and expenses. American Express earns a fee from merchants on each purchase, plus annual fees and interest on balances cardholders carry. Henry Wells and William Fargo, who later started Wells Fargo, co-founded it in 1850 as a freight delivery business; it is based in New York City.
