Overview



An established organisation working on large-scale data integration and digital transformation initiatives is seeking a Senior Data Developer. This role will focus on architecting and delivering advanced semantic web solutions that support high-value, data-driven programmes. You will lead the design, modelling, and validation of complex linked data ecosystems, and shape the standards, tooling, and best practices used across the wider engineering team.


This position is ideal for someone who thrives in technically challenging environments, enjoys designing semantic models from the ground up, and can guide both technical and non-technical stakeholders through linked data concepts.




Key Responsibilities



  • Design and maintain semantic data models and ontologies aligned with W3C standards.
  • Develop SHACL-based validation frameworks and automated testing approaches.
  • Create DCAT3-compliant metadata services and build/extend SKOS vocabularies.
  • Implement and optimise Triple Pattern Fragments for high-performance data access.
  • Translate domain requirements into robust RDF models and modelling strategies.
  • Build tools and pipelines for data harmonisation, transformation, and validation.
  • Design versioning approaches for evolving vocabularies and datasets.
  • Develop hypermedia APIs following Hydra principles.
  • Work with geospatial datasets using WKT and relevant geographic vocabularies.
  • Write, optimise, and maintain SPARQL queries and SQL-to-RDF transformation logic.
  • Produce clear technical documentation, diagrams, and architectural guides.





Deliverables



  • SHACL validation schemas with accompanying automated tests
  • Semantic data models, ontologies, and vocabulary management structures
  • DCAT3 metadata service components and SKOS vocabularies
  • Triple Pattern Fragment endpoints and Hydra-driven APIs
  • Tools for geospatial processing and data harmonisation
  • Optimised SPARQL queries and transformation scripts
  • Architecture documentation and engineering guidance





Essential Skills & Experience



  • Advanced knowledge of RDF, RDFS, OWL, SHACL, and broader semantic web technologies
  • Strong experience with SKOS, DCAT3, SOSA/SSN, and Hydra
  • Proficiency in SPARQL, SQL, data validation frameworks, and linked data design
  • Ability to convert domain requirements into scalable semantic models
  • Experience working across distributed or federated linked data architectures





Desirable Skills



  • Triple Pattern Fragments, JSON-LD APIs, performance tuning for linked data endpoints
  • Familiarity with OGC standards and geospatial/environmental data formats
  • Experience with Python (e.g., FastAPI), Docker, Git, CI/CD workflows

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.
