Synechron UK is seeking highly experienced Senior Data Scientists to lead innovative initiatives within our Credit Risk Technology team. This critical role offers the opportunity to shape the future of data and AI products through the strategic development of cutting-edge Machine Learning (ML) and Generative AI (Gen AI) solutions.



This role focuses on two key pathways:

  • Machine Learning (ML): Specialising in advanced ML algorithms and MLOps practices.
  • Generative AI (Gen AI): Focusing on deploying Retrieval-Augmented Generation (RAG) workflows and managing Large Language Model (LLM) applications.


What You’ll Do

As a Senior Data Scientist at Synechron, you will operate as a vital contributor, overseeing the full lifecycle of Data and AI products within a dynamic financial environment. Your core responsibilities include:


  • Advanced Data Analysis & Modeling: Uncover hidden patterns and develop insights pertinent to Credit Risk via sophisticated statistical, quantitative, and machine learning techniques.
  • Generative AI Applications: Leverage unstructured data, NLP, and LLMs to automate data lineage modeling and documentation processes.
  • Model Optimisation & Monitoring: Enhance model performance, detect anomalies, conduct variance and time-series analysis, and develop automated solutions for model monitoring—covering data drift and correction strategies.
  • Explainable AI for Risk: Apply advanced analytics to interpret root causes behind changes in pre-settlement risk.
  • Framework Development: Build scalable, reusable data science frameworks enabling efficient deployment of financial models.
  • Strategic Product Leadership: Lead end-to-end product lifecycle—from ideation and requirements to development, launch, and post-launch performance management.
  • Stakeholder Collaboration: Partner with senior leadership, business units, tech teams, risk, compliance, and operations to gather requirements, align priorities, and drive consensus.
  • Responsible AI & Governance: Ensure your solutions comply with strict risk, privacy, and ethical standards, including data governance and fairness in highly regulated financial settings.


Key Technologies & Tools

  • Core ML: scikit-learn, PyTorch, TensorFlow, XGBoost, LightGBM
  • Data Manipulation: Pandas, NumPy, LangGraph
  • MLOps & Orchestration: MLflow, Apache Airflow
  • Databases: Neo4j, MongoDB
  • API Development: FastAPI
  • Big Data (Beneficial): Apache Hadoop, Apache Spark (PySpark)


What We Need From You

  • 5-8 years of hands-on experience developing and deploying ML and/or Gen AI solutions in production.
  • Deep expertise in quantitative methods, probability, statistics, and numerical computing.
  • Proven MLOps proficiency—model deployment, versioning, lifecycle management, and data drift monitoring/correction.
  • Experience working in a highly regulated environment, with a bonus for Financial or Credit Risk industry exposure.
  • Exceptional communication, presentation, and stakeholder management skills—ability to influence across diverse teams.
  • Master’s degree in Data Science, Computer Science, or a related quantitative discipline.

What Hiring Managers Look for First in Data Science Job Applications (UK Guide)

If you’re applying for data science roles in the UK, it’s crucial to understand what hiring managers focus on before they dive into your full CV. In competitive markets, recruiters and hiring managers often make their first decisions in the first 10–20 seconds of scanning an application — and in data science, there are specific signals they look for first. Data science isn’t just about coding or statistics — it’s about producing insights, shipping models, collaborating with teams, and solving real business problems. This guide helps you understand exactly what hiring managers look for first in data science applications — and how to structure your CV, portfolio and cover letter so you leap to the top of the shortlist.

The Skills Gap in Data Science Jobs: What Universities Aren’t Teaching

Data science has become one of the most visible and sought-after careers in the UK technology market. From financial services and retail to healthcare, media, government and sport, organisations increasingly rely on data scientists to extract insight, guide decisions and build predictive models. Universities have responded quickly. Degrees in data science, analytics and artificial intelligence have expanded rapidly, and many computer science courses now include data-focused pathways. And yet, despite the volume of graduates entering the market, employers across the UK consistently report the same problem: Many data science candidates are not job-ready. Vacancies remain open. Hiring processes drag on. Candidates with impressive academic backgrounds fail interviews or struggle once hired. The issue is not intelligence or effort. It is a persistent skills gap between university education and real-world data science roles. This article explores that gap in depth: what universities teach well, what they often miss, why the gap exists, what employers actually want, and how jobseekers can bridge the divide to build successful careers in data science.

Data Science Jobs for Career Switchers in Their 30s, 40s & 50s (UK Reality Check)

Thinking about switching into data science in your 30s, 40s or 50s? You’re far from alone. Across the UK, businesses are investing in data science talent to turn data into insight, support better decisions and unlock competitive advantage. But with all the hype about machine learning, Python, AI and data unicorns, it can be hard to separate real opportunities from noise. This article gives you a practical, UK-focused reality check on data science careers for mid-life career switchers — what roles really exist, what skills employers really hire for, how long retraining typically takes, what UK recruiters actually look for and how to craft a compelling career pivot story. Whether you come from finance, marketing, operations, research, project management or another field entirely, there are meaningful pathways into data science — and age itself is not the barrier many people fear.
