Machine Learning Engineer

Are you ready to embark on an outstanding journey with Manulife? As a Machine Learning Engineer on our Group Function AI team, you will design and ship production-grade AI services that power Finance, Treasury, Actuarial, and emerging GenAI solutions across the enterprise. Your mix of software craftsmanship, cloud-native engineering, and machine-learning know-how will turn data-science prototypes into reliable, business-critical products.

Position Responsibilities:

• Collaborate with Data Scientists and Data Engineers to build modular, reusable ML & GenAI pipelines (feature stores, model registries, automated retraining).
• Engineer and optimize models for performance, cost, and scalability; run A/B or challenger tests and track data/model drift.
• Own production deployment: containerize models (Docker), orchestrate with Kubernetes/AKS, and automate CI/CD with GitHub Actions or Azure DevOps.
• Stand-up and maintain observability stacks (logging, tracing, metrics, alerting) to ensure SLA/SLO compliance.
• Integrate AI services into finance, treasury, and actuarial workflows via robust REST/GraphQL APIs and event streams.
• Guide solution architecture with Cloud & Security teams—infra-as-code (Terraform/Bicep), network policies, secrets management.
• Evaluate and implement GenAI patterns (prompt orchestration, RAG, guardrails) on Azure OpenAI, Databricks, and internal LLMs.
• Champion engineering best practices and mentor peers on clean code, test automation, and MLOps standards.
• Stay current with advances in ML, GenAI, and DevSecOps; introduce fit-for-purpose tools and frameworks to the team.

Required Qualifications:

• 5+ years delivering high-availability software in Python plus one statically-typed language (TypeScript, Java, Go, etc.).
• Proven experience operationalizing ML/GenAI models in cloud environments (Azure preferred) using Docker, Kubernetes/AKS, MLflow or Azure ML.
• Hands-on with CI/CD pipelines, unit/integration tests, code-quality scanning, and blue-green or canary releases.
• Advanced SQL skills and proficiency with both relational (PostgreSQL, SQL Server) and NoSQL/analytic stores (CosmosDB, Delta Lake).
• Big-data processing using Spark/Databricks; ability to build high-throughput ETL/ELT and feature-engineering workflows.
• Experience deploying or fine-tuning LLMs (GPT-series, Llama 2/3, BERT, etc.) and working with vector databases (Elastic, Azure Cognitive Search, Pinecone).
• Exposure to secure, regulated domains—Finance, Insurance, Actuarial, or Treasury—and the ability to translate complex business logic into reliable code.
• Demonstrated ability to balance urgency with delivering high-quality, well-documented solutions.

Preferred Qualifications:

• Bachelor’s degree in Computer Science, Software Engineering, Data Science, Mathematics, or a related technical field (or equivalent industry experience).
• Master’s degree in a relevant discipline is an asset and may substitute for part of the required experience.

When you join our team:

• We’ll empower you to learn and grow the career you want.
• We’ll recognize and support you in a flexible, inclusive environment where well-being truly matters.
• As part of our distributed Group Function AI team, you’ll shape the next generation of AI that drives Manulife’s global success.
