Senior MLOps Engineer
As an MLOps Engineer, you will play a pivotal role in designing, building, and operating the platforms, pipelines, and infrastructure that enable machine learning solutions to move reliably from experimentation to production. This is a blended role combining MLOps, Data Engineering, and DevOps, well-suited to an engineer who enjoys working across the full ML and data lifecycle.
You will work within dynamic, multi-disciplinary project teams, collaborating closely with data scientists, software engineers, and client stakeholders to deliver scalable, production-ready ML and data solutions across a diverse range of commercial sectors.
This role offers strong opportunities for career development, exposure to real-world ML systems, and continuous learning within a fast-growing engineering team.
Key Responsibilities & Skills:
Own and manage the end-to-end lifecycle of machine learning models, including development, training, deployment, monitoring, and continuous improvement.
Productionise ML models built with PyTorch, TensorFlow, or Scikit-learn, ensuring reliability, scalability, and security.
Implement model versioning and experiment tracking using MLflow, along with controlled releases, rollback strategies, and continuous improvement workflows.
Design, build, and optimize robust data pipelines in Databricks, feeding ML models and analytics workloads.
Develop and maintain scalable data architectures including Azure Data Lake, Azure SQL Data Warehouse, and Synapse Analytics.
Build and maintain reliable ETL/ELT workflows, ensuring high data quality, accessibility, and performance.
Collaborate with data scientists and analysts to translate business and data requirements into production-grade ML pipelines.
Develop and maintain CI/CD pipelines for software, data, and ML workflows using tools such as Azure DevOps, Git, and Jenkins.
Automate model training, testing, validation, and deployment using MLflow and Databricks Jobs.
Automate infrastructure provisioning, environment management, and deployment using Terraform, ARM templates, or Ansible.
Essential Technical Skills:
Programming: Python, SQL, PySpark, Bash
ML Frameworks: TensorFlow, PyTorch, Scikit-learn
MLOps & Model Management: MLflow, Model versioning, CI/CD
Cloud & Big Data: Databricks, Databricks APIs, MCP, Blob Storage
Data Engineering: ETL/ELT pipelines, DLT, Delta Lake
Infrastructure as Code (IaC): Terraform, ARM templates, Ansible
Version Control & DevOps: Git, Azure DevOps, Jenkins
Experience
3+ years of experience in ML/MLOps engineering or a similar role.
Proven track record of delivering data solutions in a consulting or client-facing environment is a plus.
Experience with Agile or Scrum methodologies is beneficial.
The role will principally centre on MLFlow as an MLOps platform, but similar experience in platforms such as SageMaker or VertexAI is a definite benefit.
