Junior Data Engineer 

Work alongside a senior engineer to build production systems for a multi-billion-pound 100% family-owned real estate group.

The opportunity 

We are a private, entrepreneurial family-owned real estate platform with a multi-billion-pound property portfolio and private credit book. We are hiring a junior data engineer to support a senior engineer in building the organisation's internal data platform. 

The first leg of this role will revolve around building the data platform to connect a variety of specialist domains including property management, asset management and accounting. 

Your role 

• Developing and maintaining a Python codebase and database responsible for ingesting, cleaning, validating and reconciling data from internal and third-party data sources. 

• Building REST APIs to serve as the bedrock of an internal platform. 

• Investigating inconsistencies in existing internal data, writing validation rules, document definitions and help establish trusted datasets for asset management. 

• Turning manual collection, checking, reconciliation, reminders, document generation and reporting tasks into dependable workflows. 

• Creating dashboards, reports, alerts and small internal tools for investment, asset-management, finance and operations functions. 

• Develop document extraction, retrieval and LLM-based workflows, with testing, evals, and human-in-the-loop review mechanisms. 

• Write clean, tested and high-quality code; use version control; monitor jobs; investigate failures; and maintain clear technical documentation. 

What we are looking for 

• A rigorous degree in Computer Science, Data Science, Engineering, Mathematics or a closely related discipline. Oxford Computer Science graduates are particularly encouraged to apply, alongside candidates from other programmes with equivalent strength. 
• Strong programming fundamentals in Python, Typescript and SQL. Confident working knowledge demonstrated through useful software, research, internships, open-source work or a strong personal portfolio. 
• An understanding of and experience with relational databases, data modelling, APIs and ETL/ELT pipelines, with an enthusiasm to deepen these skills. 
• Care for readable code, testing, debugging, version control and the difference between a promising prototype and a reliable production system. 
• The patience to trace messy data through unfamiliar systems, identify root causes and verify that a solution works. 
• Commercially minded individual with an ability to think out of the box, and an appetite to build and scale a platform 
• Strong professionalism and maturity.
• The ability to ask good questions, document decisions and explain technical issues to colleagues who do not write code. 
• A grounded, collaborative and high-agency approach: willing to seek guidance, act on feedback and take increasing responsibility as capability grows. 

Helpful, but not essential 

• Internship, placement, research or project experience involving data pipelines, backend engineering, analytics engineering or automation. 
• Familiarity with a cloud platform for application deployment, Docker, data warehouses or, business-intelligence tools. or simple internal web applications.

• Interest in real estate, finance, accounting, asset management, construction or how operational businesses actually use data. 
• Evidence that you have the knack to go beyond the teaching syllabus: a tool, service, open-source contribution, technical article or project used by someone other than you. 

Confidentiality and inclusion

• Appointment will be subject to appropriate references, background checks and a confidentiality agreement. We welcome applicants from different backgrounds whose skills and evidence meet the requirements, and reasonable adjustments are available throughout the process.
