And now we’re looking for more brilliant people to join us on our journey.

The Role

Plum is reaching a pivotal moment in our growth.

As we approach CASS Large Firm classification, the manual, spreadsheet-heavy processes that served us in our early stages are no longer fit for purpose.

We are looking for a Senior Data Engineer to architect and build our next-generation Reconciliation & Controls Platform.

This is not a reporting role.

You will own the entire lifecycle of our financial integrity systems, moving us from fragmented, manual workflows to a hardened, automated, and audit-ready infrastructure.

You will be the bridge between complex engineering and regulatory rigor; designing and deploying dedicated reconciliation tooling to standardise our data control frameworks, enhance auditability, and ensure long-term operational resilience.

What You Will Do

• Design and implement robust ETL/ELT workflows that replace manual spreadsheet‑based reconciliations with scalable, monitored, and fully automated processes.
• Continuously optimise system architecture to onboard new product models and partner providers smoothly without adding operational overhead.
• Build and maintain automated reporting pipelines that meet EU & UK regulatory and audit requirements, ensuring consistent, traceable, and fully auditable outputs.
• Decouple core reconciliation logic from the BI layer to ensure operational stability independent of reporting tools or analytics infrastructure changes.
• Develop intelligent alerting, break classification, and exception‑routing workflows that prioritise issues by materiality and provide full traceability for stakeholders.
• Iterate and refine data pipelines based on operational feedback to constantly improve system performance, data quality, and reliability.

Who you are

• 3+ years in Data Engineering or a similar backend data infrastructure role.
• Strong SQL and Python skills; hands‑on experience with Big Query or a comparable cloud data warehouse.
• Experience designing and operating ELT workflows with tools such as Airflow and dbt.
• Experience with financial data reconciliation processes (breaks, exception management, and control frameworks) is highly preferred.
• Experience building systems that meet audit, regulatory, or compliance requirements.
• Ability to work cross‑functionally with Finance, Compliance, Product, and Engineering teams and communicate technical concepts to non‑technical stakeholders.
• Familiarity with GCP and Terraform is a plus.
• Experience developing internal platforms or full‑stack applications is a plus.
• Plum Perks
• We're all in this together! Own part of the company through stock options
• Private health insurance
• Annual training budget
• Plum Premium for you and 2 friends or family
• Referral scheme: earn competitive rewards
• Flexible approach to remote working: we encourage at least 2 days a week in one of our beautiful offices in London, Athens or Cyprus
• Team breakfasts and team lunches.
• 25 days holiday + bank holidays
• 45 work‑from‑anywhere days: giving you the flexibility to work your way.
• 2 weeks sabbatical after 4 years to take the break you deserve.
• Enhanced parental leave
• 1 paid volunteering day annually

• Annual team trip: to a surprise destination!

• A fun, inclusive company culture (think )

If this sounds like you, we’d love to hear from you!

• Thanks,
• Team Plum
