Senior Data Engineer

JLL empowers you to shape a brighter way.  

Our people at JLL are shaping the future of real estate for a better world by combining world class services, advisory and technology for our clients. We are committed to hiring the best, most talented people and empowering them to thrive, grow meaningful careers and to find a place where they belong.  Whether you’ve got deep experience in commercial real estate, skilled trades or technology, or you’re looking to apply your relevant experience to a new industry, join our team as we help shape a brighter way forward.   

About the Role

We are looking for a Senior Data Engineer with deep data engineering expertise and proven experience applying Agentic AI to production systems to join our Azara Data & AI Engineering team at JLL Technologies. You will own the design and delivery of critical data pipelines, platform components, and agentic workflows that power Azara, our AI-driven data intelligence platform for commercial real estate. Beyond individual delivery, you will set technical direction for your domain, mentor P1/P2 engineers, and drive engineering best practices across the team. This role is ideal for a senior engineer who wants to architect enterprise-scale data platforms while pushing the boundaries of what Agentic AI can automate in data engineering.

Key Responsibilities

Data Engineering & Platform Architecture

• Architect and lead the design of scalable, fault-tolerant data ingestion, transformation, and serving pipelines using Python and PySpark on Databricks
• Own end-to-end design of data services and APIs (FastAPI) that expose curated data assets to downstream applications and AI services, including versioning and backward-compatibility strategy
• Define data modeling standards, Delta Lake table design, and lakehouse architecture patterns adopted across the team
• Drive pipeline monitoring, alerting, and data quality frameworks that ensure reliability and SLA compliance at scale
• Lead orchestration strategy across Azure Data Factory, Airflow, or Databricks Workflows, optimizing for cost, latency, and maintainability

Agentic AI Leadership

• Architect AI agents that automate complex data engineering tasks — self-healing pipelines, root-cause anomaly detection, automated data quality remediation — and define reusable patterns for the team
• Lead development of agentic workflows using LangGraph or LangChain that integrate with enterprise data platforms, including multi-agent orchestration for complex data automation
• Design and productionize LLM-powered natural language to data query capabilities (e.g., Databricks Genie-style interactions), including evaluation and guardrail strategy
• Set standards for integrating LLM APIs (Azure OpenAI) into data services for intelligent enrichment, classification, and summarization, balancing accuracy, latency, and cost
• Own RAG pipeline architecture that leverages data assets as knowledge sources for agent workflows, partnering with AI engineers on retrieval quality and vector store design

Data Platform & Cloud Infrastructure

• Own architecture decisions for data models, Delta Lake tables, and lakehouse components on Databricks and Azure, evaluating trade-offs across performance, cost, and scalability
• Design data access patterns, caching (Redis), and partitioning strategies for high-throughput data serving
• Lead design of event-driven data workflows using Azure Service Bus and Dapr for real-time pipeline triggers
• Architect distributed task processing (Celery) strategies for scalable, async data workloads
• Drive CI/CD and infrastructure-as-code maturity for data platform components, reducing deployment risk and lead time

Quality & Engineering Practices

• Set the standard for unit and integration testing (pytest) across pipeline logic, data transformations, and AI-integrated components
• Lead code reviews with a focus on data quality, pipeline reliability, and AI-specific risks (hallucination, cost, prompt safety, drift)
• Define structured logging and observability standards for pipeline health and AI workflow performance
• Champion data governance, security, and compliance practices for enterprise data handling, identifying gaps before they become incidents

Technical Leadership & Mentorship

• Mentor P1/P2 data engineers through code review, pairing, and design guidance, actively growing their technical depth
• Lead design discussions and technical reviews for major features, influencing architecture decisions across the team
• Own a data domain end-to-end, from requirements through production operation, with minimal oversight
• Drive adoption of AI-augmented development practices and emerging Agentic AI frameworks across the team
• Partner with the engineering manager on technical roadmap, estimation, and risk identification for the domains you own

Required Qualifications

• 6+ years of professional data engineering experience with deep proficiency in Python and SQL
• Proven track record architecting and operating data pipelines on a cloud data platform (Databricks, Azure Synapse, or equivalent) at production scale
• Strong hands-on experience with PySpark or equivalent distributed data processing frameworks, including performance tuning
• Experience owning data orchestration strategy (Azure Data Factory, Airflow, Databricks Workflows, or similar) across multiple pipelines or domains
• Deep familiarity with Delta Lake, lakehouse architecture, or similar open table formats, including schema evolution and optimization
• 2+ years of hands-on experience building and shipping AI/ML integrations, LLM-powered features, or agent frameworks (LangGraph, LangChain, or equivalent) in production
• Experience with Python web frameworks (FastAPI preferred) for building and scaling data services and APIs
• Demonstrated experience mentoring engineers and leading technical design for medium-to-large initiatives
• Experience with AI-powered development tools (Cursor AI, GitHub Copilot, or similar) for AI-augmented development across the SDLC
• Strong Git and collaborative development workflow experience, including branching strategy and release management
• Solid working knowledge of Microsoft Azure cloud platform
