Company mission
Strategy consultancy meets product studio: We build AI-powered tools that turn data into decisive competitive advantage.
Role
Who you are
- This isn't a graduate role, so to succeed you'll need real production experience. But you don't need to have done it all independently yet. We're looking for someone with strong foundations who is ready to grow quickly with the right support around them
- Circa 3 years of experience in data engineering, analytics engineering, or a closely related role, with hands-on exposure to production environments
- Competency with SQL across multiple database platforms
- Python proficiency for data manipulation and pipeline work (Pandas, SQLAlchemy)
- Hands-on experience with cloud data warehouses (Snowflake, BigQuery, or Redshift)
- Familiarity with data modelling concepts and ELT/ETL design patterns
- Clear communicator: comfortable explaining technical concepts to non-technical stakeholders
- Collaborative and reliable in cross-functional teams
- Organised enough to manage multiple workstreams without things falling through the cracks
- Curious and keen to keep developing: data engineering is a fast-moving space
What the job involves
- We're looking for Data Engineers at Mid and Senior level who are passionate about turning complex data into actionable insights that drive remarkable results for our clients
- Why this role will accelerate your career
- We know that at this stage of your career, the right environment matters as much as the role itself. Here's what that looks like at QuantSpark:
- Real career growth: Our last hire at this level moved to Senior Data Engineer within 18 months. It reflects the pace at which people develop when they're working across varied, complex client problems rather than maintaining a single internal stack
- Training budget that you'll actually use: We invest £6,000 per person per year in learning and development and we mean it. People use it for master's degrees, industry conferences, and professional certifications
- Client exposure from day one: In your first year you'll work across multiple client engagements spanning FTSE 100 companies, PE-backed portfolio businesses, and government departments. The breadth of exposure you'll get here could take five years or more to accumulate in a single in-house role
- Mentorship that's built in: You'll work alongside talented senior engineers who are invested in your development; technically and in how you navigate client relationships
- We believe in being upfront about what joining a scale-up consultancy actually looks like:
- Messy data: Real client data is rarely clean. You'll need creativity and rigour to build pipelines that handle edge cases, missing data, and evolving schemas
- Varied stacks: Each client brings different tools and constraints. Adaptability matters more than knowing every platform in advance
- Building while flying: We're still maturing some of our data engineering standards. You'll help shape them, which is an opportunity as much as an ambiguity
- Speed vs. quality: Clients need results quickly, and our reputation depends on delivering robustly. Holding that balance is a skill we'll help you develop
- Reports to: Engineering Manager
Salary benchmarks
Our take
QuantSpark helps governments and businesses to strategically apply data science through the development of complex decision-making software. Primarily, its work involves analysing large datasets and systems in order to understand customer behaviour and help clients make informed decisions for strategic planning in sales and marketing.
In recent years, big data has become central to the operation of businesses large and small, and this has led to great demand for data scientists fluent in sophisticated modelling and analysis. QuantSpark seeks to go a step further, providing a service which combines data science with commercial insight- effectively providing both services through one transaction. By doing this, QuantSpark hopes to offer clients a more meaningful insight into their data than a standard consultancy could.
Already, the company has an impressive client list, including the UK Government, the Australian Government and Bain Capital. QuantSpark's tools and solutions are developed to become embedded in its clients' operations, ensuring a long-lasting relationship between them, and meaning that, as QuantSpark continues to expand its client base, its model should allow it to see continued success in the future.
