The successful candidate will be responsible for designing, developing, and optimizing scalable cloud-based data solutions that support critical Risk, Finance, Treasury, Regulatory, and Management Reporting capabilities. This role combines hands-on technical delivery with solution design, data architecture, and stakeholder engagement, requiring an individual who can translate complex business requirements into robust, enterprise-grade data solutions.

  • Develop and optimize ELT/ETL pipelines to support enterprise reporting, analytics, and regulatory requirements.
  • Design and implement dimensional, analytical, and operational data models.
  • Develop and maintain reusable transformation frameworks using dbt.
  • Build Python-based data processing, automation, and integration solutions.
  • Develop data ingestion processes from multiple internal and external source systems.
  • Support cloud migration and data platform modernization initiatives.
  • Contribute to solution architecture, engineering standards, and platform design decisions.

Performance, Quality & Governance

  • Optimize Snowflake databases, workloads, and SQL queries to improve performance, scalability, and cost efficiency.
  • Implement data quality controls, reconciliation processes, and monitoring frameworks.
  • Troubleshoot complex production, performance, and data integrity issues.
  • Ensure solutions adhere to enterprise security, governance, and regulatory standards.
  • Support code reviews, testing, release management, and CI/CD delivery practices.
  • Maintain technical documentation and promote engineering best practices across the data platform.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
