Senior Data Engineer (Founding Platform Lead)

Our client is a private, entrepreneurial, family owned real estate platform with a multi billion pound property portfolio and private credit book. They're building their first proper tech function from scratch, and this is the founding hire to lead it.

This is a founding level hire. You'll take on a high ownership role, defining the technical roadmap and building the data platform that connects a business that has never had one, shaping how the organisation runs going forward rather than maintaining someone else's system.

What they need built

  • A robust data model acting as a single source of truth, reconciling properties, entities, leases, tenants, projects, invoices, cash flows, valuations and documents across multiple data sources.
  • Integrations with third party vendors via APIs, webhooks, database access and scheduled ingestion.
  • Automation that eliminates repetitive manual work across data collection, validation, approvals, reconciliation, reminders, document generation and reporting.
  • Dashboards, reports, alerts and internal applications that principals and operating teams can actually trust and use.
  • LLM pipelines for extraction, classification, retrieval and workflow support, built with evals, human in the loop oversight and auditability.

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.

How you'd work

  • With genuine autonomy, balancing a robust platform architecture against rapid delivery.
  • Setting the standards for security, testing, deployment, monitoring and documentation as you go, since none currently exist.
  • Managing selected vendors and building the engineering culture from the ground up.
  • Mentoring a junior data engineer as the team grows.
  • Close to the business, handling financially sensitive, personal and commercially confidential information with mature judgement in a regulated environment.

What they need

  • A strong record of building and operating reliable pipelines, integrations, data models or platforms serving real users and business critical decisions.
  • Strong programming fundamentals in Python, TypeScript and SQL, with the ability to review and maintain a high quality bar for other contributors' code.
  • Confidence building robust REST APIs, working with relational databases such as PostgreSQL, modelling data, building ETL/ELT pipelines, and making pragmatic build versus buy calls.
  • Experience deploying production systems on AWS, Azure or GCP, including monitoring, secrets management, access control, backups and disaster recovery.
  • Experience with production LLM pipelines, covering context engineering, evaluation, retrieval, tool use and guardrails.
