• Architect and own production ML infrastructure for training, deployment, serving and monitoring at scale
• Set the standards for CI/CD, automation, model delivery and ML lifecycle management used across all teams
• Stay hands-on, building Python services, APIs and platform tooling that support production ML workloads
• Own reliability, observability, performance, availability, security and cost across production ML systems, including SLOs, incident response and on-call practices
• Lead the technical response to complex production issues across software, infrastructure and ML workflows, and turn the lessons into lasting platform improvements
• Make and communicate key architecture and build-vs-buy decisions, aligning ML engineers, data engineers, product teams and leadership on priorities and trade-offs
• Help shape engineering culture, best practices and technical hiring as the team scales

• Strong Python skills, plus experience with web frameworks such as FastAPI, Flask or Django
• Extensive hands-on experience with Docker, CI/CD pipelines and cloud environments (we use Azure)
• A track record of making architecture decisions and running complex production systems for reliability, scalability and performance
• Experience defining engineering standards, best practices and operational processes adopted across teams
• Excellent communication and stakeholder management skills, with the ability to influence technical and non-technical audiences
• A collaborative style that brings out the best in others and builds a high-ownership engineering culture

Preferred Skills

• Expertise with Kubernetes and infrastructure as code, such as Terraform
• Experience with ML lifecycle tooling such as MLflow, Weights & Biases or similar platforms
• Knowledge of monitoring and observability tools such as Prometheus, Grafana, ELK or OpenTelemetry
• Experience with distributed ML workloads, model serving, GPU infrastructure, performance tuning and cloud cost optimisation
