Northern Trust
About Northern Trust
Northern Trust, a Fortune 500 company, is a globally recognized, award‑winning financial institution that has been in continuous operation since 1889. Northern Trust is proud to provide innovative financial services and guidance to the world’s most successful individuals, families, and institutions by remaining true to our enduring principles of service, expertise, and integrity. With more than 130 years of financial experience and over 22,000 partners, we serve the world’s most sophisticated clients using leading technology and exceptional service.
The Enterprise AI team at Northern Trust performs data science research and develops custom prototypes to problems that 1) are not adequately addressed by available commercial solutions, 2) enhance the customer and/or internal partner experience and 3) provide Northern Trust with a competitive advantage. We are at the forefront of rolling out Generative AI solutions and frameworks for the bank from Proof of Concepts, full stack development of solutions and vendor evaluations. We also serve to inspire and empower applied data science practitioners by facilitating high‑quality data science education and collaboration within Northern Trust as well as with top universities and research institutions.
Role Summary As a Senior AI Engineer, you will be a key player in developing, deploying, and maintaining state‑of‑the‑art Generative AI solutions within the Azure cloud environment. Your role will focus on building and refining Large Language Models (LLM) and RAG systems on Azure infrastructure, ensuring they meet business requirements and enterprise‑level standards.
Responsibilities
Develop software, typically in Python, to independently acquire data from disparate sources (databases, files, APIs, etc.) and combine them into appropriate training, validation, and testing datasets.
Analyze raw datasets using descriptive statistics, working directly with domain experts to understand the meaning of data fields.
Have a deep understanding of Generative AI and LLMs, evaluation metrics and theory behind LLMs & conversational AI, since Gen AI will be a core part of many solutions being developed at the Bank.
Explain the full pattern of Retrieval Augmented Generation (RAG) and make recommendations on which technologies and techniques to use when building solutions based on this pattern, developing and integrating RAG systems on Azure cloud.
Leverage open‑source AI software like TensorFlow, PyTorch, HuggingFace, LangChain, AutoGen, LangGraph and LamaIndex for the solution development and evaluation.
Evaluate various AI frameworks and services for efficacy and make recommendations on their inclusion as standardized tooling for AI development.
Integrate these tools and software with Azure services for a seamless development and deployment experience.
Leverage Terraform for automating cloud provisioning of resources and other infrastructure tasks.
Build unit tests, data quality checks and data pipelines to ensure that algorithms use trusted data.
Implement CI/CD pipelines using Azure DevOps, ML‑Ops, GitHub Actions, Terraform for automated deployment of AI solutions.
Utilize Azure Kubernetes Service (AKS) for managing and scaling containerized AI applications.
Regularly update and maintain the AI models, ensuring their relevance and effectiveness using Azure monitoring tools.
Enforce strict security measures and controls in Azure, including network security configurations and identity management, data encryption and privacy.
Comply with industry standards, best practices and regulations for AI solutions.
Work across multiple projects in a fluid environment where work spans the full research lifecycle from forming a hypothesis, acquiring data, and developing ETL‑style software to presenting findings.
Provide guidance to other software development teams as prototypes and frameworks are engineered for full production environments.
Key Experience
IAC and automation concepts with various tools.
Full‑stack Azure application development.
Security related concepts and controls, particularly in the cloud environment: virtual networks, subnets, private endpoints, authentication mechanisms, identities and role‑based access.
Data protection and encryption techniques and tooling such as Key Vaults, encryption keys, masking and BYOK.
DevOps including CI/CD techniques and tools particularly Azure‑based and GitHub repos.
Develop and maintain an understanding of many algorithms across supervised learning, unsupervised learning and time‑series analysis.
Propose and develop machine learning ensemble methods that exhibit the best out‑of‑sample characteristics possible given the input dataset.
Utilize expertise in machine learning algorithms to tune algorithms using available hyper‑parameters and carefully select feature subsets.
Discover biases or leakage in datasets and ensure that train/test splits reflect realistic expectations of real‑world performance.
Run large‑scale (parallel or distributed) training and inference jobs on private or public cloud infrastructure.
Present findings to internal and external customers using both data science language (F1 scores, regression error, statistical significance, etc.) and business‑domain specific language gained from experience analyzing the data in scope.
Plan and execute data science training sessions and hackathons.
Work with external parties (vendors, universities, etc.) to incorporate new techniques and tools into the data science lab.
Develop open‑source software in a collaborative environment (desired but not required).
Tools / Languages Required: Python, NumPy, Pandas, scikit‑learn, Linux‑based operating systems, basic development tools (Python IDEs, source control, etc.).
Preferred: Advanced distributed machine learning frameworks (e.g., Keras, TensorFlow) and Azure cloud infrastructure.
Education Computer Science degree (undergraduate or graduate level) and strong statistical background.
Preferred: Data Science graduate work, Finance sector experience or coursework.
Certification
Certifications in Azure Security or DevOps are preferred, but not required.
Azure AI Engineer Associate or equivalent are preferred, but not required.
Salary Range $114,500 – $194,700 USD.
Benefits Northern Trust provides a comprehensive benefits package including retirement benefits (401k and pension), health and welfare benefits (medical, dental, vision, spending accounts and disability), paid time off, parental and caregiver leave, life & accident insurance, and other voluntary and well‑being benefits.
A discretionary bonus program that may include an equity component is also available.
Working With Us As a Northern Trust partner, greater achievements await. You will be part of a flexible and collaborative work culture in an organization where financial strength and stability is an asset that emboldens us to explore new ideas. Movement within the organization is encouraged, senior leaders are accessible, and you can take pride in working for a company committed to assisting the communities we serve. Join a workplace with a greater purpose.
