Quant Data Engineer

The Role:

As a Quant Data Engineer, you will be joining a small but growing team working closely with Pythia’s quant modellers to ensure they have access to reliable, well-structured and high-quality data for research, modelling and analysis.

With particular emphasis on data quality, usability, investigation and continuous improvement, you will work side-by-side with quant, engineering and operational colleagues to prepare datasets, improve underlying data flows and help ensure that the data feeding our models is accurate, complete and fit for purpose.

Your experience in handling complex datasets, building robust Python-based data workflows and investigating data issues will be key as we continue to expand our modelling capabilities and data inputs. From preparing historical datasets to assessing new data sources and improving existing ones, you will play a central role in helping Pythia extract maximum value from its data.

Sharing our passion for delivering fantastic solutions, you will leave no stone unturned to help drive Pythia’s success and to be part of getting us to the next level.

3 Best Things About the Job:

  1. Impactful Work: You will work directly with quant modellers on the data that underpins core research, modelling and decision-making.
  2. Complex Challenges: You will engage with intricate real-time and historical datasets from diverse sources, helping turn messy inputs into reliable modelling assets.
  3. Pioneering Solutions: You will tackle unique data problems that sit at the heart of predictive sports modelling.

  • 28 days + Bank Holidays leave
  • Purchase up to 5 extra days of holiday/year
  • Casual dress
  • Company events
  • Cycle to work scheme
  • Flexible schedule
  • Private medical insurance
  • Optical and Dental cover
  • Generous paternity and maternity leave
  • Referral programme

Responsibilities

Quant Data Support

  • Work day-to-day with quant modellers to prepare, refine and maintain datasets used for research, modelling and analysis
  • Help improve the structure, quality and usability of underlying data so that it can be consumed efficiently by quant workflows
  • Investigate data issues affecting modelling outputs, identifying root causes and working with relevant teams to resolve them
  • Support the development of repeatable data preparation processes that make research datasets more reliable, consistent and easier to work with
  • Proactively review existing and new data sources to determine what can be consumed, how it should be processed and where improvements are needed

Data Preparation & Engineering

  • Build and maintain Python-based data workflows and supporting pipelines for ingestion, transformation and validation of modelling data
  • Maintain and further develop Pythia’s historical data assets, ensuring they remain accurate, accessible and fit for analytical use
  • Work with engineers to improve upstream and downstream data flows, helping ensure that critical data is captured and processed effectively
  • Support data migrations, backfills and structural improvements where required to improve the usefulness and reliability of modelling datasets
  • Contribute to the development of tooling and processes that make it easier to explore, prepare and troubleshoot data used by the quant team

Data Quality, Investigation & Improvement

  • Ensure data quality and integrity through validation, reconciliation and targeted monitoring across key datasets
  • Expand visibility into data issues by improving checks, alerts and investigative workflows across critical pipelines and sources
  • Define and improve data logic, transformations and assumptions, ensuring they are clearly documented and consistently applied across datasets
  • Improve the clarity and usability of data through better documentation, metadata management and standardisation of definitions
  • Work closely with engineering and operational teams to resolve anomalies, gaps and inconsistencies in source data
  • Contribute to the ongoing evolution of Pythia’s data capabilities, balancing immediate modelling needs with longer-term improvements to data quality and maintainability

Measures of Success

In the first three months, you will have:

  • Fully understood the key datasets, data flows and modelling dependencies across the platform
  • Built strong working relationships with quant modellers and become a trusted partner in preparing and investigating data
  • Contributed to meaningful improvements in at least one modelling dataset, data workflow or data quality process
