Senior Platform Engineer - Azure Data & AI Platform

The Role

Weare looking forsenior platform engineers to build and operate our Azure-based data and AI platform. This is hands-on infrastructure and platform work - you’ll be writing Terraform, designing network architecture, implementingMLOps(AImodel)pipelines, and establishing DevSecOps patterns that engineering teams canuse.

This isn’t a “thought leadership” or “strategy” role. You’ll be in the code, in the CLI, and in the infrastructure daily.

What You’ll Actually Do

Azure Platform Engineering (40%)

• Design and implement Azure landing zones, management groups, and subscription architecture
• Build and maintain hub-spoke network topologies with proper segmentation and security controls
• Implement Azure Policy, RBAC, and governance frameworks that balance security with developer productivity
• Manage identity and access using Entra ID, service principals, managed identities
• Establish monitoring, logging, and alerting with Azure Monitor, Log Analytics, and Application Insights
• Cost management and FinOps practices - keeping cloud spend under control without hamstringing teams

Databricks & Data Platform (30%)

• Deploy and configure Azure Databricks workspaces with Unity Catalog for data governance
• Assisting both data and AI teams withpipelinedevelopment
• Establish Databricks best practices: cluster policies, job scheduling, notebook standards, workspace organization
• Integrate Databricks with ADLS Gen2, Azure SQL, Synapse, and other data services
• Set up and maintain CI/CD for Databricks notebooks, jobs, and infrastructure
• Work with data engineers on performance optimization, cost control, and platform capabilities

MLOps & AI Platform (20%)

• Build ML model deployment pipelines using Azure ML, Databricks MLflow, or both
• Implement model versioning, experiment tracking, and model registry patterns
• Establish inference endpoints (batch and real-time) with proper monitoring and governance
• Create reusable ML pipeline templates and infrastructure-as-code modules
• Integrate AI services (Azure OpenAI, Cognitive Services) into platform offerings
• Implement responsible AI guardrails: model monitoring, bias detection, explainability

DevSecOps & PlatformEnablement(10%)

• Creation of tools, features and dashboards for the developer platform
• Build CI/CD pipelines in Azure DevOps or GitHub Actions with proper security scanning
• Implement shift-leftsecurity: SAST/DAST, dependency scanning, infrastructure scanning, secrets management
• Establish infrastructure-as-code standards with Terraform (or Bicep), including modules and policy enforcement
• Create self-service tooling and automation for common platform tasks
• Write documentation that engineers willreadand use
• Participate in on-call rotation for platform incidents

What We NeedFromYou

Required

• 5+ years platform/infrastructure engineering - you’ve built production platforms, not just prototypes
• Deep Azure knowledge - networking, IAM, storage, compute, PaaS services. You know the difference between service endpoints and private endpoints and when to use each
• Databricks experience - you’ve deployed workspaces, configured Unity Catalog, optimized Spark jobs, managed costs
• Infrastructure as Code - Terraform (preferred) or Bicep. You write modules, understand state management, know how to structure large IaC projects
• CI/CD pipelines - Azure DevOps or GitHub Actions. You’ve built multi-stage pipelines with gates, approvals, and security scanning
• Containerization experience – youknowbest practiceswhen building and working withbothapplication-basedcontainers andcontainersholdingML/AI models
• Security-first mindset - you understand defense in depth, least privilege, network segmentation, and don’t treat security as an afterthought
• MLOps fundamentals - model training vs inference, experiment tracking, model versioning, deployment patterns
• Python and/or PowerShell - for automation, tooling, and platform utilities
• Observabilitystack beyond basic metrics (distributed tracing, log aggregation patterns)

Strongly Preferred

• Experience with Azure landing zones and CAF (Cloud Adoption Framework)
• Microsoft Purview for data governance and cataloging
• Experience with Delta Lake, Spark optimization, data quality frameworks
• Azure networking certifications or equivalent deep knowledge
• Container orchestration (AKS)
• API design and management (API Management, App Gateway, Front Door)

What Actually Matters

• Pragmatism over purity - you choose the right tool for the job, not the coolest one
• Documentation discipline - you document as you build because you know future-you will thanktoday-you
• Automation mindset - if you do it twice, you automate it
• Everything-as-code – - if it’s not in git, it doesn’t exist to you
• Collaboration skills - you can translate between data scientists, engineers, and business stakeholders
• Ownership mentality - you build it, you run it, you support it
• Intellectual honesty - you say “I don’t know” when you don’t, and then you figure it out
