We’re building AI products that move from promising prototypes to reliable, production-grade systems with measurable business impact. This role blends LLM application engineering, applied data science, and data engineering fundamentals.
You will own the end-to-end data operations lifecycle: sourcing and understanding data, designing scalable pipelines, enabling analytics and model development, and partnering with engineering and data science to productionize solutions. You will translate complex data into context for humans and AI applications, implement durable processes.
You’ll design, evaluate, deploy, and continuously improve GenAI systems (RAG, agentic workflows, model fine-tuning) while helping shape the data foundation that makes them trustworthy at scale.
Position Responsibilities:
- Design, evaluate, and deploy RAG pipelines, agentic systems, and chat interfaces, including advanced retrieval methods and modular designs.
- Conduct LLM red-teaming, bias detection, and alignment testing; build automated evaluation frameworks and develop measurement/feedback loops.
- GenAI engineering in the Azure ecosystem: integrate and test LLMs using OpenAI APIs, Azure AI Services, Azure AI Search/Cognitive Search, Azure ML, Databricks, and (where applicable) AKS/Kubernetes.
- Develop and implement ML models (traditional + GenAI) and design/execute experiments to validate, optimize, and scale solutions.
- Contribute to fine-tuning and pre-training pipelines for domain use cases; use synthetic data generation and creative data sourcing to improve modeling outcomes (including sparse/rare-event problems).
Data acquisition & domain understanding
- Identify, evaluate, and obtain access to internal and external data sources with minimal guidance.
- Partner with subject matter experts to understand data definitions, quality, lineage, and business context.
- Document datasets using standard templates (metadata, assumptions, refresh cadence, known issues) and present findings to stakeholders.
Data engineering & platform delivery
- Design, build, and maintain robust ETL/ELT pipelines to extract, transform, and stage data for AI/ML and BI consumption.
- Create and manage tables, schemas, and databases; implement data models that support analytics and machine learning use cases.
- Productionize pipelines and datasets with monitoring, alerting, data quality checks, and performance tuning.
- Collaborate with internal/external engineers and data scientists to integrate data science solutions into production systems.
Analytics, measurement & reporting
- Deliver ad-hoc analysis, business analytics, and reporting for projects of moderate scope/complexity.
- Define metrics and acquire data to measure solution effectiveness; communicate results and recommendations to peers and stakeholders.
- Build dashboards and reporting assets (e.g., Tableau/Power BI/Qlik) to support decision-making.
Process design & operational excellence
- Help design scalable operating processes to implement analytics/AI insights, including:
- Clear roles and responsibilities across partners
- Defined workflows, system/data flows, and contingencies
- Checks-and-balances (validation, QA, approvals)
- KPI tracking and closed-loop learning to continuously improve outcomes
Communication & mentorship
- Partner with Data Engineers, ML Engineers, BI, IT, and business leaders; participate in code/model reviews, documentation, agile delivery, and mentorship.
- Communicate moderately complex technical and analytical topics to senior team members and business partners.
- Build a strong internal network and leverage senior peers to accelerate delivery.
Required Qualifications:
Education & experience
- Bachelor’s degree in Computer Science, Engineering, Math, or equivalent practical experience.
- 2+ years of relevant experience in data engineering, analytics engineering, or BI/analytics roles supporting AI/ML or advanced analytics.
- Advanced degree (MS/PhD) in a quantitative field or equivalent depth through impactful work; publications or research contributions are a plus.
Technical skills
- Strong programming skills in Python; advanced SQL proficiency; Java experience is asset.
- Advanced experience with data transformation and modeling for analytics/BI and ML feature readiness.
- Strong understanding of relational databases and data modeling concepts.
- Working knowledge of distributed computing concepts/tools.
- Advanced experience with data visualization tools
Analytics/ML foundations
- Ability to explore and mine large structured and unstructured datasets using a systematic approach.
- Familiarity with statistics and common analytical techniques (e.g., regression, clustering, PCA, decision trees, survival analysis).
- Basic understanding of machine learning algorithms and familiarity with common AI/ML toolkits.
- Hands-on experience with RAG, embeddings, semantic search, and vector databases (e.g., FAISS, MongoDB, Neo4j) and/or graph-based analytics.
- Knowledge of GenAI frameworks such as LangChain, Semantic Kernel, and agent frameworks (e.g., Autogen / LangGraph / CrewAI-style tools).
(Optional) Include with your application
- 1–2 examples of work (GitHub, write-ups, papers, demos, etc.) showing:
- something you built end-to-end,
- how you evaluated quality and failure modes,
- and how you iterated based on evidence and constraints.
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 environment where well-being and inclusion are more than just words.
- As part of our global team, we’ll support you in shaping the future you want to see.
