Make your mark at one of the biggest names in payments. We're looking for a Senior Data Scientist to join our ever evolving Authorisation Management Performance team and help us unleash the potential of every business.


What you'll own as the Senior Data Scientist

As a Senior Data Scientist, you will lead efforts to forecast trends and automate processes using complex, unstructured data. You'll design predictive models and algorithms to drive payment optimisation and strategic decision-making.


Working with a diverse and cross border team, you'll be responsible for developing, interpreting, and implementing concepts for uplifting authorisation approvals and controls.


Key Responsibilities

  • Primary Focus - Predictive & Prescriptive - building models to forecast future trends using large, complex, unstructured data.
  • Build predictive and prescriptive models using machine learning and big data models.
  • Implement algorithms to automate analysis processes.
  • Deliver automated insights and visual summaries for stakeholders.
  • Explore open-ended business challenges and design experiments.
  • Translate data into new/enhanced capability and functionality requirements.
  • Output should show payment optimisation insights with solution recommendations to key stakeholders and decision makers.

Key areas in which you will add value

  • Own the responsibility for identifying and resolving the biggest authorization issues, from identifying issues through dashboards and data interrogation to owning the resolution and tracking impact delivered.
  • Collaborate internally to submit issues for resolution, track success, and refine the operating model between teams for greatest success.
  • Use analytics and insights to identify areas for improvement, bottlenecks, and opportunities on authorization issue investigation.
  • Establish robust impact tracking to demonstrate authorization enhancement programme achievements, shared to senior leadership.
  • Facilitate the exchange of feature requests between the authorization teams and tooling team for continuous development of authorisation monitoring tooling (executive & operational dashboards, root cause analysis, near‑time alerting, etc.).
  • Support the development of a knowledge codification library for the broader authorization team, and cross‑team learning and alignment calls with key stakeholders.

What you'll bring

  • Bachelor's degree in computer science or equivalent proficiency in programming languages, ML libraries, and big data platforms.
  • Strong knowledge of the payments industry & IT technologies.
  • Desirable but not essential: broad knowledge of Worldpay products and related services; in-depth knowledge of products and services for which teams provide support.
  • Excellent verbal and written communication skills to technical and non‑technical audiences at various levels: executive, management, individual contributors.
  • Experience in authorization investigation and resolution.
  • Excellent problem‑solving and time‑management skills.
  • Willingly share knowledge and expertise with other resources.
  • Ability to work independently and collaboratively.
  • Deep understanding of the payments industry and authorization pathways (e.g., gateways, platforms, acquirers, networks, issuers, etc.).
  • Experience with authorization investigation & resolution; strong analytical skills to understand investigation approaches and tackle complex matters.
  • Strong leadership and communication skills, and strong project management skills.
  • Understanding (but not detailed expertise) of requirements for engineering ticket submissions and converting business requirements to product stories, PI process, etc.
  • Some flexibility of hours is required.

Bonus

  • Strong existing connections within the Worldpay business (e.g., product, commercial or operational) & ability to drive new cross‑business collaboration.
  • Knowledge and experience with differing platforms (e.g., WPG, VAP, NAP) and merchant profiles (e.g., needs and issues of smaller vs larger merchants).

Data Science Recruitment Trends 2025 (UK): What Job Seekers Need To Know About Today’s Hiring Process

Summary: UK data science hiring has shifted from title‑led CV screens to capability‑driven assessments that emphasise rigorous problem framing, high‑quality analytics & modelling, experiment/causality, production awareness (MLOps), governance/ethics, and measurable product or commercial impact. This guide explains what’s changed, what to expect in interviews & how to prepare—especially for product/data scientists, applied ML scientists, decision scientists, econometricians, growth/marketing analysts, and ML‑adjacent data scientists supporting LLM/AI products. Who this is for: Product/decision/data scientists, applied ML scientists, econometrics & causal inference specialists, experimentation leads, analytics engineers crossing into DS, ML generalists with strong statistics, and data scientists collaborating with platform/MLOps teams in the UK.

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.
