About the Role
We are looking for a Senior Application Developer to design and build a robust PostgreSQL-based data platform that will underpin our investment reporting, risk analytics, regulatory disclosures and performance measurement. This is a genuinely high-impact, greenfield opportunity. You will have real ownership of the platform design and lead the migration away from Databricks and Excel-driven processes — leaving a lasting mark on infrastructure that sits at the heart of our investment operations.
What You’ll Be Doing

- Portfolio holdings and valuations
- Performance and attribution reporting
- Risk analytics
- Regulatory and trustee reporting
- Operational data governance
You will migrate structured data from Databricks (Delta Lake/Spark) and replace Excel-based workflows with automated, controlled pipelines — ensuring accuracy, auditability and compliance with regulatory requirements at every step.
