Junior data engineer

Junior Data Engineer – Public SectorContract: Initial 7 months (extension possible) Rate: £310 per day, Inside IR35 Location: Remote with travel to Waterloo (2–3 days per month) Security Clearance: SC‑eligible (5 years UK residency required)We’re working with a key consultancy delivering a major UK public sector programme and are looking for a Junior Data Engineer to join a mixed delivery team building and operating secure, reliable data platforms that support critical public services.This role is designed for someone early in their data career who wants to develop strong engineering fundamentals in a real production environment.The role – a junior, generalist data engineering positionThis is an engineering‑led role, not a specialist or senior position. The team is ideally looking for a generalist in their first few years within data engineering or data science, who is building breadth across data platforms, pipelines and operations.You’ll focus on:

Designing, building and maintaining data pipelines

Supporting the operation of data lakes and data warehouses

Implementing and improving ETL / ELT processes

Using Python and SQL to transform, validate and move data

Working with analysts and developers to turn data requirements into technical solutions

Monitoring data quality, documenting data models and lineage, and resolving issues

Automating data workflows and operational tasks

Participating in Agile delivery, sprint work and collaboration

Supporting incidents and helping improve platform reliability over time

Working within public sector dataernance, security and privacy standards

This role offers exposure to how data platforms are built, operated and supported in a regulated environment — forming the foundations of a long‑term data engineering career.What this role is notTo avoid misalignment, it’s important to be clear about what this role is not focused on:

Not a Data Analyst role

Not a Power BI / dashboard developer role

Not an insight, reporting or MI position

Not a modelling, ML or research‑focused role

Not an LLM, AI or advanced data science role

While you may work alongside analysts and data scientists, this role does not centre on:

Building dashboards

Producing insights or reports

Statistical modelling

Predictive or machine learning solutions

The emphasis is on data engineering foundations and platform delivery.Ideal candidate profileThis role is best suited to someone who:

Is in their first few years of a data engineering or data science career

Wants to build core engineering skills rather than specialise immediately

Has hands‑on experience with SQL and Python

Understands basic data modelling and ETL concepts

Isfortable learning through delivery in a production environment

Is interested in how data platforms work end‑to‑end, including operations and support

Is keen to grow within public sector data platforms

Who this role is unlikely to suitThis role is unlikely to be appropriate for candidates who:

Are very senior data engineers or architects

Have primarily worked in advanced ML, AI, or research‑focused roles

Are specialised Power BI, reporting or MI developers

Are looking for a role centred on analysis, insights or modelling

Are seeking leadership, ownership of platform strategy, or advanced optimisation work

Applications that demonstrate significant seniority or deep specialisation rather than junior‑to‑mid generalist experience may not be progressed.Required skills and experienceYour CV should clearly demonstrate:

A degree in a technical discipline puter Science, Data Science, Mathematics or similar)

Hands‑on experience with SQL

Experience using Python, Java or Bash

Understanding of ETL processes and data modelling fundamentals

Experience with version control ( Git)

Awareness of data security and privacy

Eligibility for UK SC clearance

Nice to have (but not essential)

Exposure to AWS, Azure or GCP

Familiarity with tools such as Airflow, dbt, Spark

Awareness of CI/CD pipelines or containerisation

Experience in public sector or regulated environments

Important note for applicantsThis role is deliberately positioned as a junior, generalist data engineering role. Please ensure your CV clearly demonstrates hands‑on data engineering fundamentals, rather than senior leadership, advanced AI/ML work, or analytics‑only experience. #4790246 - Jonathan Clough
