- Build and maintain modular, reusable ML and GenAI pipelines, including data processing, feature engineering, model training, evaluation, deployment, and monitoring.
- Operationalize traditional ML models and predictive analytics solutions, including classification, regression, forecasting, risk scoring, segmentation, and anomaly detection.
- Implement GenAI and LLM-based solutions, including retrieval-augmented generation, prompt orchestration, document intelligence, summarization, classification, and intelligent workflow automation.
- Deploy models and AI services into production using modern engineering practices such as containerization, CI/CD, automated testing, version control, and cloud-native infrastructure.
- Monitor production models for performance, data drift, model drift, bias, accuracy degradation, latency, cost, and reliability using established MLOps and LLMOps practices.
- Build observability capabilities, including logging, tracing, metrics, alerts, dashboards, and service-level monitoring.
- Collaborate with Risk, Legal, Compliance, Security, Architecture, and Cloud teams to ensure AI solutions are secure, compliant, explainable, and aligned with enterprise standards.
- Support model governance activities, including documentation, validation, auditability, model lineage, and responsible AI controls.
- Evaluate and adopt fit-for-purpose tools, frameworks, and platforms across Azure, Databricks, Azure OpenAI, MLflow, vector databases, and internal AI platforms.
- Engineer AI services that integrate with business workflows through APIs, event-driven architecture, batch pipelines, and enterprise applications.
- Continuously improve solution quality, scalability, maintainability, and cost efficiency.
- Stay current with emerging trends in AI, ML, GenAI, LLMOps, software engineering, cloud platforms, and financial services technology, and share relevant learnings with the team.
- Mentor junior engineers and data scientists on production engineering standards, clean code, testing, monitoring, and MLOps/LLMOps best practices.
Required Qualifications
- 3+ years of experience in AI Engineering, ML Engineering, Software Engineering, Data Science Engineering, or a related technical role.
- Strong programming skills in Python, with experience building reliable, maintainable, and production-quality code.
- Proven experience deploying ML or AI models into production cloud environments.
- Hands-on experience with MLOps practices, including model versioning, model registry, CI/CD, automated testing, monitoring, retraining workflows, and production support.
- Experience monitoring model performance in production, including accuracy, drift, latency, stability, reliability, and business performance indicators.
- Strong understanding of traditional machine learning and predictive analytics techniques, including supervised learning, unsupervised learning, feature engineering, model evaluation, and experimentation.
- Practical experience with GenAI and LLM-based solutions, including prompt engineering, RAG, embeddings, vector search, evaluation, and guardrails.
- Experience working with cloud platforms, preferably Azure, and tools such as Azure ML, Azure OpenAI, Databricks, MLflow, Docker, Kubernetes/AKS, GitHub Actions, or Azure DevOps.
- Strong SQL skills and experience working with structured and unstructured data.
- Experience with data engineering concepts, including ETL/ELT, Spark, Databricks, Delta Lake, data quality, and scalable data pipelines.
- Strong understanding of software engineering best practices, including API design, unit testing, integration testing, code reviews, documentation, and secure development.
- Ability to work with cross-functional teams and communicate technical concepts clearly to both technical and non-technical stakeholders.
- Demonstrated ability to balance speed, quality, risk, and long-term maintainability.
Preferred Qualifications
- Bachelor’s degree in Computer Science, Software Engineering, Data Science, Mathematics, Statistics, Engineering, or a related technical field, or equivalent industry experience.
- Master’s or PhD degree in a relevant discipline is an asset.
- Experience in insurance, financial services, healthcare, Long-Term Care, claims, underwriting, risk management, or operations is an asset.
- Experience with model governance, responsible AI, explainability, fairness testing, or regulated AI environments.
- Experience with document intelligence, claims analytics, call center analytics, workflow automation, or knowledge management solutions.
- Experience with vector databases or search technologies such as Azure AI Search, Elastic, Pinecone, FAISS, or similar tools.
