The Opportunity

We’re looking for a Senior Data Engineer who pairs solid engineering fundamentals with an analytical mindset. You’ll build reliable data foundations, enable high-quality reporting and self-serve analytics, and help us take our Power BI capability to the next level. We care more about attitude, work ethic, and proven delivery than formal qualifications.

What you’ll do
  • Design, build, and maintain scalable data pipelines and ELT/ETL processes across telematics, ERP, IoT, CRM, and finance systems.
  • Model and deliver robust data products (lakehouse/warehouse, marts, semantic models) that power BI, analytics, and data science.
  • Lead our use of Microsoft Fabric for ingestion, transformation, and analytics, including Lakehouse, Warehouse, Pipelines, Notebooks, Dataflows Gen2, and OneLake.
  • Build and optimise Power BI datasets and semantic models (including Direct Lake and incremental refresh) in partnership with analysts.
  • Implement data governance, quality, lineage, and security-by-design; drive documentation, testing, and version control standards.
  • Tune performance across SQL, storage, and BI layers; manage cost and reliability in the cloud (Azure preferred).
  • Enable streaming and near-real-time use cases where needed (e.g., telematics/IoT) using appropriate services.
  • Champion modern DataOps practices (CI/CD, environment management, automation) and mentor junior team members.
  • Collaborate closely with stakeholders to translate business needs into well-designed data solutions and clear metrics.
What you’ll bring (essential)
  • Proven experience (5+ years) as a data engineer delivering production-grade data solutions.
  • Strong SQL and proficiency in at least one programming language (Python preferred; Scala/Java also valuable).
  • Hands-on experience building and operating ETL/ELT pipelines and data models (Kimball, Data Vault, or similar).
  • Cloud data experience (Azure preferred), including storage, compute, and security fundamentals.
  • Practical Power BI experience as a data engineer: shaping data models, optimising for performance, and collaborating with analysts.
  • Solid grasp of data governance, privacy, and security best practices; comfortable with Git and documentation.
  • Bias to action, ownership, and continuous improvement; capable of balancing speed with quality.
Nice to have
  • Microsoft Fabric: creating and managing a Fabric Warehouse or Lakehouse (and underlying “database” objects), building Pipelines/Notebooks, using OneLake, and enabling Direct Lake for Power BI.
  • Experience with telematics, IoT, logistics, or construction data.
  • Streaming platforms and APIs (e.g., Kafka, Event Hubs) and batch orchestration.
  • DataOps/CI-CD for data (Azure DevOps/GitHub Actions), dbt, unit/integration testing for data.
  • DAX fundamentals and Power BI performance tuning at scale.
  • Formal qualifications or certifications (e.g., Azure DP-203, Microsoft Fabric Analytics Engineer) are welcome but not required.
What success looks like in 6–12 months
  • Reliable, well-documented pipelines feeding a governed lakehouse/warehouse.
  • Faster, more trusted Power BI reporting backed by high-quality semantic models.
  • Clear data standards adopted across the team, with CI/CD and automated testing in place.
  • Demonstrable cost, performance, and data quality improvements on key domains (e.g., telematics, operations, finance).
Benefits
  • Competitive salary and package.
  • 24 days plus bank holiday annual leave, plus personal leave.
  • Training and professional development tailored to you.
  • Employee Assistance Programme.
  • Strong safety and sustainability culture.
  • Modern equipment and supportive, team-oriented environment.
  • Recognition programmes for outstanding performance.

If you’re a hands-on engineer who loves building practical, scalable data solutions and wants to grow an organisation’s Power BI and Microsoft Fabric capability, we’d like to hear from you.

How Many Data Science Tools Do You Need to Know to Get a Data Science Job?

If you’re trying to break into data science — or progress your career — it can feel like you are drowning in names: Python, R, TensorFlow, PyTorch, SQL, Spark, AWS, Scikit-learn, Jupyter, Tableau, Power BI…the list just keeps going. With every job advert listing a different combination of tools, many applicants fall into a trap: they try to learn everything. The result? Long tool lists that sound impressive — but little depth to back them up. Here’s the straight-talk version most hiring managers won’t explicitly tell you: 👉 You don’t need to know every data science tool to get hired. 👉 You need to know the right ones — deeply — and know how to use them to solve real problems. Tools matter, but only in service of outcomes. So how many data science tools do you actually need to know to get a job? For most job seekers, the answer is not “27” — it’s more like 8–12, thoughtfully chosen and well understood. This guide explains what employers really value, which tools are core, which are role-specific, and how to focus your toolbox so your CV and interviews shine.

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.
