DATA ENGINEERING AND BIG DATA
TALENT SOLUTIONS
Processing Big Data has become crucial to countless businesses. Those who decide to pursue a career within Big Data face complex development challenges, too tough for relational database systems. After all, there is no Data Science without Data Engineers.
Whilst businesses may have vast quantities of data at the ready, it holds no real value unless it can be stored, harnessed and utilised. It’s estimated that most UK companies have at least 100 terabytes of data stored which could be used for various purposes around the business, as well as newly accessible hard-to-process sources such as web data, image data, and social media data.
This is where those who work in Data Engineering become extremely valuable, as they develop Data Platforms that allow this kind of volume to be processed and used by Data Scientists and analysts across the business.

Start: 1st May
The Role
A growing data team within the digital/consumer sector is looking for a SQL‑first Analytics Engineer to help build out a robust, scalable analytics layer. You’ll be joining a small, collaborative team focused on strengthening data models, improving governance, and laying the foundations for AI‑driven analytics.
This role sits at the intersection of data modelling, analytics engineering, and modern AI‑enablement. You’ll transform raw data into well‑structured, trusted datasets that support decision‑making across the business – while also helping shape a semantic layer designed for future AI and LLM‑powered use cases.
You’ll be joining at a pivotal moment: the platform is in place, proof‑of‑concepts are underway, and the team needs someone who can own modelling, testing and semantic design from day one.
What You’ll Be Doing
- Designing and building clean, scalable data models for analytics, reporting, and self‑serve
- Writing highly efficient SQL to transform raw data into business‑ready datasets
- Using SQLMesh (or similar frameworks such as dbt) to orchestrate transformations
- Working with stakeholders to understand key business questions and model data accordingly
- Improving data quality, testing, documentation and governance
- Contributing to the development of a strong semantic layer to support AI/LLM adoption
- Exploring opportunities to integrate AI into analytics workflows and automation
- Ensuring data structures, metadata and context enable accurate natural‑language querying
- Understanding downstream impact – supporting analysts, engineers and business users
What We’re Looking For
- Strong SQL‑first mindset – SQL as your primary problem‑solving tool
- Proven experience with transformation frameworks (SQLMesh, dbt, or similar)
- Solid understanding of data modelling principles and trade‑offs
- Experience building models in cloud data warehouses (Snowflake, BigQuery, Redshift, etc.)
- Ability to design intuitive, business‑friendly datasets
- Understanding of data architecture and how layers fit together
- Curious, pragmatic, collaborative – comfortable working in a small team
- Strong communication skills and willingness to ask for support when needed
Bonus Points
- Experience designing data models to support AI/ML or LLM‑based analytics
- Interest in using AI tools to enhance developer productivity
- Exposure to semantic layers or metrics layers
- Experience with customer data
- Ability to make thoughtful, real‑world trade‑offs in data design
Why This Role Has Come About
The team is scaling up its engineering capability and investing heavily in AI‑driven analytics. They’ve brought in another contractor and are now looking for someone who can:
- Strengthen and extend existing data models
- Build a robust semantic layer
- Support AI proof‑of‑concepts
- Improve governance and testing
- Ensure analytics models are reliable, well‑documented and scalable
This role will be critical in shaping how the business uses data – both operationally and through new AI‑enabled workflows.
Interview Process
- 1‑hour interview with the Data Lead
- Skills assessment focused on SQL, modelling, and analytics engineering
- Immediate availability – interviews scheduled this week
Contract Details
- £400 per day
- Inside IR35
- 6‑month contract
