About the role
The Lead Platform Engineer is the senior technical lead for CF’s data platform, combining design authority over platform architecture, helping to mentor and direct the data engineering team and managing delivery of platform and data engineering workstreams.
The role sits within CF’s unified data function (Data Innovation and Data Ops), which is led by the Director of Data, Analytics and Intelligence, as the most senior role within the function’s Data Ops team. Within the team this role sits alongside the Lead Data Scientist(s).
Operating with delegated design authority from the Director of Data, Analytics and Intelligence, the Lead Platform Engineer translates the company’s strategic architectural direction into detailed technical designs, implementation patterns and platform standards, enabling the engineering team to execute against them.
They bring deep technical expertise, experience and knowledge to support the Director in delivery and the strategic architecture, technology strategy, vendor relationships, commercial targets and regulatory frameworks within which the Lead Platform Engineer operates.
They help to coach and manage the data engineer(s) within the Data Operations team. They own the day to day management of the platform and lead data engineering and infrastructure workstreams. They own the platform, infrastructure and data engineering capability that underpins it. The Lead Platform Engineer works collaboratively with the Lead Data Scientist(s), who manage the data science consulting track and direct delivery for the client-facing technical consulting team.
The Lead Platform Engineer contributes to CF’s commercial activities in a focused way: providing technical expertise to support partnership opportunities with platform vendors such as Databricks and with data and research organisations and contributing technical input to proposals where platform architecture or infrastructure design is relevant.
