Project Delivery Model (PDM) is a talent model that is tailored specifically for long-term, onsite client service delivery.

Work you'll do/Responsibilities

As a Platform Engineer Consultant, we are seeking a hands-on Senior Data & AI Engineer with deep expertise in the Databricks platform, Python/PySpark development, and emerging agentic AI frameworks. This role combines traditional data engineering/platform operations with modern AI orchestration, requiring someone equally comfortable tuning Spark jobs as debugging an LLM agent's tool-calling loop.

Responsibilities;

• Troubleshoot cluster, job, and workflow failures across Databricks (compute, networking, permissions, library conflicts)
• Perform cost optimization: cluster right-sizing, job cluster vs. all-purpose cluster strategy, auto-scaling policies, spot/on-demand mix, DBU usage analysis
• Conduct performance tuning: Spark query optimization, partitioning strategies, caching, Photon engine utilization, Delta Lake optimization (Z-ordering, compaction, vacuum)
• Administer and automate platform usage via the Databricks REST API and SDKs (workspace provisioning, job orchestration, cluster policies, Unity Catalog management)

Python & PySpark Development

• Build and maintain production-grade ETL/ELT pipelines
• Write performant, testable PySpark code for large-scale distributed data processing
• Apply software engineering best practices (version control, CI/CD, code review, unit/integration testing)

AI / Agentic AI Development

• Design, build, and deploy at least one AI agent end-to-end - from use case definition through production deployment
• Call and orchestrate LLMs (prompt design, context management, tool/function calling, multi-step reasoning chains)
• Implement agent workflows using frameworks such as LangChain and LangGraph (state machines, multi-agent orchestration, tool routing)
• Instrument and monitor agent behavior using LangFuse or similar observability tools (tracing, evaluation, prompt versioning, cost/latency monitoring)
• Collaborate with data scientists/ML engineers to productionize AI-driven features

Azure Cloud Infrastructure

• Design and manage Azure Storage Accounts (ADLS Gen2, blob storage, access tiers, lifecycle policies) integrated with Databricks
• Implement secure secrets management using Azure Key Vault (service principals, managed identities, Databricks secret scopes)
• Work across core Azure services supporting the data platform (e.g., Azure Data Factory, Azure Monitor/Log Analytics, Virtual Networks, Entra ID/RBAC, Azure Databricks workspace configuration)

Infrastructure as Code & Containerization

• Author and maintain Terraform modules for provisioning Databricks workspaces, Azure resources, and networking
• Manage version-controlled, modular IaC with proper state management practices
• Deploy and manage containerized workloads on Kubernetes (deployments, services, scaling, resource management); integrate with Databricks where applicable (e.g., model serving, custom containers)
