- Partner with the Platforms team to oversee infrastructure‑as‑code deployments using Pulumi, Docker, Kubernetes and cloud‑native services (Azure, AWS).

- Lead, coach and guide a team of engineers, fostering a culture of best practices in coding, testing, and documentation alongside a culture of continuous learning and psychological safety.

- Partner with stakeholders across the business such as Operations to translate business requirements into technical solutions.

What you’ll bring

- 7+ years experience in data engineering, with at least 2 years experience leading a team, ideally in a fast paced, high growth environment.

- Strong proficiency in Apache Airflow, dbt, and Azure Data Factory.

- Expertise in Snowflake, including advanced SQL, performance optimisation, and security features.

- Hands‑on experience deploying and integrating Generative AI models (OpenAI, Hugging Face, or similar).

- Solid understanding of data governance frameworks and compliance requirements (GDPR, CCPA).

- Proficiency in Python and SQL; familiarity with PySpark or other distributed processing frameworks is a plus.

- Experience with cloud platforms (Azure, AWS) and infrastructure‑as‑code tools (Pulumi, Terraform).

- Strong CI/CD skills with Azure Pipelines or equivalent.

- Excellent communication skills, with the ability to interact effectively with technical and non‑technical stakeholders

- Strong problem solving skills, with a continuous learning mindset.
