  • Backend Development: Design, build, and maintain serverless and traditional backend architectures using best practices. (We build on AWS using Lambdas and ECS images - largely in NodeJS.)
  • ETL Pipeline Management: Develop and optimise data pipelines to enable seamless data flow and transformation. (We currently use a mix of SSIS, ETL Works, Airflow, Snowflake and are moving to Airflow/Snowflake only architecture.)
  • Snowflake Management: Create production‑ready procedures in Snowflake for moving and analysing data.
  • System Optimisation: Improve existing backend systems for enhanced performance, scalability, and reliability. (We're migrating away from an old ERP monolith to a SAAS architecture. On top of this, there's always new systems arriving for different teams across the business!)
  • Cross‑functional Collaboration: Work with teams across finance, marketing, and supply chain to support data needs and align technical solutions with business objectives.
  • Technical Leadership: Provide guidance on architecture decisions, ensuring that solutions are aligned with long‑term technical goals and day to day team leadership.
  • Data Governance & Security: Ensure compliance with GDPR, data retention policies, and Jollyes' information security standards
  • Documentation & Standards: Establish best practices for coding, version control, and deployment across the data stack. (Currently, we use Bitbucket, but have poor documentation.)

Why Data Science Careers in the UK Are Becoming More Multidisciplinary

Data science once meant advanced statistics, machine learning models and coding in Python or R. In the UK today, it has become one of the most in-demand professions across sectors — from healthcare to finance, retail to government. But as the field matures, employers now expect more than technical modelling skills. Modern data science is multidisciplinary. It requires not just coding and algorithms, but also legal knowledge, ethical reasoning, psychological insight, linguistic clarity and human-centred design. Data scientists are expected to interpret, communicate and apply data responsibly, with awareness of law, human behaviour and accessibility. In this article, we’ll explore why data science careers in the UK are becoming more multidisciplinary, how these five disciplines intersect with data science, and what job-seekers & employers need to know to succeed in this transformed field.

Data Science Team Structures Explained: Who Does What in a Modern Data Science Department

Data science is one of the most in-demand, dynamic, and multidisciplinary areas in the UK tech and business landscape. Organisations from finance, retail, health, government, and beyond are using data to drive decisions, automate processes, personalise services, predict trends, detect fraud, and more. To do that well, companies don’t just need good data scientists; they need teams with clearly defined roles, responsibilities, workflows, collaboration, and governance. If you're aiming for a role in data science or recruiting for one, understanding the structure of a data science department—and who does what—can make all the difference. This article breaks down the key roles, how they interact across the lifecycle of a data science project, what skills and qualifications are typical in the UK, expected salary ranges, challenges, trends, and how to build or grow an effective team.
