The role ⚡
📍 London (Hybrid) | 🤝 2 days in the office | 💰 Competitive Salary + Benefits
The Data Platform team builds and runs the platform that all Funding Circle data teams use. This includes our Snowflake platform, streaming and batch ingestion, orchestration, data contracts, and the Data Product Portal.
We are in the middle of a big change. We are moving to Snowflake and to a federated "Data as a Product" model. This role will lead the engineering of that platform.
- Lead the technical direction of the Data Platform. Turn the target architecture into a clear, sequenced engineering plan, and keep the team aligned to it.
- Own the technical quality of the platform: Snowflake infrastructure and RBAC, ingestion patterns, orchestration (Airflow), CI/CD, observability, and cost controls.
- Make and record technical decisions. Run the decision-document process. Make the final call when the team cannot agree, and escalate cross-domain decisions to the architecture review board.
- Grow the team. Mentor engineers, spread knowledge so that no system depends on one person, and set a review culture that is fast and deep.
- Make it easy for domain teams, Data Scientists, Analysts, and AI Agents to build on the platform. Define standards and reusable patterns. Make sure that DP reviews do not block the domain teams, and work closely with the teams that use the platform.
- Lead the platform side of the Athena → Snowflake migration: source landing, reconciliation and cutover evidence, and decommissioning of the legacy platform.
- Own operational excellence with the Engineering Manager: on-call quality, alert quality, incident follow-ups, runbooks, and disaster recovery.
- Own security and governance controls on the platform with Security and Data Governance.
- Manage the technical relationship with platform vendors. This includes support cases, escalations, and roadmap input.
- Explain technical trade-offs clearly to non-technical stakeholders and data leadership.
- Set and evolve the team's standards for AI-assisted engineering, so that tools like Claude and Copilot are used safely and consistently.
- Work closely with the Principal Engineer. The Principal owns the cross-domain architecture. You turn it into the platform engineering plan and make sure the team delivers it.

- Experience designing end-to-end data pipelines. Combining batch, file-based, and streaming ingestion (Kafka/CDC) managed with Airflow orchestration.
- A good understanding of data security and governance, including PII handling and access control.
- Strong infrastructure-as-code skills and CI/CD skills.
- Track record of writing clear design docs, explaining technical risks to non-technical stakeholders, and making decisions under uncertainty.
