You’ll be instrumental in scaling our machine learning capabilities from experimentation to production across multiple use cases.

ESSENTIAL JOB DUTIES & RESPONSIBILITIES

Infrastructure Architecture & Engineering

• Lead the architecture and implementation of production-grade ML infrastructure using Azure Machine Learning, AKS, Azure Data Lake, Azure Databricks, and related services.

• Design scalable training and inference environments for deep learning and traditional ML workloads, optimizing performance and cost.

MLOps Strategy & Execution

• Define and implement MLOps best practices: versioning, CI/CD for ML pipelines, monitoring, and model governance.

• Automate end-to-end ML workflows using tools such as MLFlow, Azure ML Pipelines, or Kubeflow.

• Build reusable templates and frameworks to standardize ML deployment across teams.

Cross-Functional Leadership

• Collaborate with data scientists to productionize models, offering guidance on infrastructure, deployment strategies, and performance optimization.

• Partner with DevOps and platform engineering teams to align infrastructure with broader cloud strategies and compliance standards.

• Mentor junior ML and platform engineers, sharing best practices and driving engineering excellence.

Security, Reliability, and Observability

• Implement enterprise-grade security and compliance controls using Azure Active Directory, RBAC, and data encryption strategies.

• Integrate observability tooling (e.g., Azure Monitor, Prometheus, Grafana) for end-to-end monitoring of ML systems.

• Ensure systems are highly available, reliable, and scalable to meet the demands of production ML workloads.

EDUCATION

• Bachelor’s degree in Computer Science, Information Systems, or a related field, or equivalent practical experience in lieu of formal education.

• Legal IT experience a plus but not required

SKILLS AND EXPERIENCE

Required

• 5+ years of experience in ML infrastructure, cloud engineering, or MLOps

• 2+ years of experience working in Azure environments.

• Deep hands-on experience with Azure cloud services relevant to ML, including Azure Machine Learning, AKS, Blob Storage, Databricks, Azure Data Factory, and Synapse.

• Strong expertise in containerization (Docker) and orchestration (Kubernetes, preferably AKS).

• Proficient in Python and scripting languages (e.g., Bash, PowerShell).

• Advanced knowledge of CI/CD tools such as Azure DevOps, GitHub Actions, or Jenkins for ML workloads.

• Solid understanding of IaC tools: Terraform, Bicep, or ARM templates.

Preferred

• Microsoft Azure certifications (e.g., Azure AI Engineer Associate, Azure Solutions Architect Expert, or DevOps Engineer Expert).

• Experience designing ML infrastructure in regulated industries (finance, healthcare, etc.).

• Familiarity with feature stores, distributed training, and model monitoring frameworks.

• Leadership experience in building infrastructure for ML at scale.

WHY YOU WILL LOVE THIS ROLE

• Lead the development of high-impact ML platforms that support real-world AI applications.

• Influence the direction of our ML and cloud infrastructure strategy.

• Work in a forward-thinking, collaborative team that values experimentation, clean architecture, and automation.

• Competitive salary, equity opportunities, and comprehensive benefits.

• Continuous learning budget and Azure certification support.
