- Drive innovation through automation, containerisation, and performance optimisation across hybrid and multi-cloud environments.
- Team Leadership & Mentoring
- Provide mentorship and technical direction to DevOps engineers and cross-functional teams, fostering a culture of collaboration, learning, and engineering excellence.
- Support team development through coaching, knowledge sharing, and hands-on guidance in DevOps best practices.
- Lead by example in driving high standards for reliability, security, and delivery velocity.
- Platform Reliability & Automation

- Ensure platform availability and performance through proactive monitoring, alerting, and incident response.
- Operational Excellence
- Define and implement observability, logging, metrics, and incident management.
- Lead root cause analysis and post-incident reviews, leading to platform improvements.
- Continuously improve operational processes and tooling to enhance platform resilience and developer productivity.
- Security & Compliance
- Implement robust security controls, secrets management, and compliance monitoring in line with organisational and regulatory requirements.
- Collaborate with security and governance teams to ensure infrastructure and data services meet required standards.
- Cross-Functional Collaboration
- Work closely with data engineers, architects, and product teams to align DevOps practices with platform and business goals.
- Act as a trusted adviser on DevOps strategy, tooling, and operational readiness for data-centric projects.
- Lead DevOps efforts across project-based initiatives, including system upgrades, platform modernisation, and integration of new tools into the operational architecture.
- Support the delivery of enterprise data pipelines in regulated environments (e.g. finance, government), ensuring compliance, scalability, and performance.
Skills & Experience:
- Experience in a senior or principal DevOps engineering role, ideally within data-intensive or regulated environments.
- Strong software development background with experience in distributed, highly scalable, and cloud-based systems architecture.
- Deep expertise in infrastructure-as-code (e.g., Terraform, Pulumi), CI/CD tooling (e.g., GitHub Actions, Jenkins, GitLab CI), and container orchestration (e.g., Kubernetes).
- Proficiency in scripting and automation (e.g., Python, Bash, Go).
- Experience with Azure and hybrid/multi-cloud deployments.
- Familiarity with data platform technologies and workflows (e.g., Spark, Airflow, Kafka, Lakehouse architectures).
