🚀 Senior Data Engineer (Contract – Outside IR35)

📍 UK-Based | Remote / Hybrid | Defence, Government & High-Assurance Environments

⏳ Contract | Outside IR35


🔍 The Opportunity

Are you a Senior Data Engineer who thrives in high-assurance, mission-critical environments?

This is a chance to shape secure, resilient data platforms that sit at the heart of national defence, government, and regulated-sector programmes.

You’ll engineer robust data pipelines, cross-domain integrations, and secure-by-design platforms that enable controlled data sharing across complex multi-classification ecosystems.

If you’re motivated by meaningful impact, technical depth, and delivering quality at scale—this contract is for you.


🛠️ What You’ll Be Doing

  • Designing and building secure, scalable data pipelines and integration services
  • Engineering data solutions for cross-domain and multi‑classification environments
  • Writing production-grade Python, plus Java/Scala where needed
  • Modelling complex datasets to enable controlled, interoperable data access
  • Integrating data from diverse and sometimes legacy operational systems
  • Implementing fine-grained access controls, classification rules & governance frameworks
  • Deploying data services across cloud, hybrid, and on‑prem environments
  • Working closely with architects, security engineers, and delivery teams
  • Contributing to design reviews, technical assurance, and architectural decisions
  • Ensuring platforms are resilient, observable, and high-performing
  • Producing high-quality technical docs for a range of stakeholders


🧠 What You’ll Bring

Core Technical Skills

  • Strong commercial experience as a Senior Data Engineer
  • Excellent Python engineering capability
  • Commercial Java and/or Scala
  • Advanced SQL + strong data modelling
  • Expertise in large-scale ETL/ELT pipelines
  • Solid understanding of distributed systems
  • Experience across AWS, Azure, or GCP
  • Knowledge of Docker, Kubernetes, containerisation & orchestration
  • Familiarity with CI/CD and modern DevOps practices


🔐 Security, Defence & Government Experience

  • Experience building data solutions in secure/regulated environments
  • Understanding of zero-trust architecture & least-privilege models
  • Implementing data classification & policy-driven governance
  • Working with systems subject to formal assurance, audit & compliance
  • Comfortable handling sensitive or protected information


⭐ Nice to Have

  • Knowledge of semantic data, knowledge graphs or graph DBs
  • Experience with RDF, SPARQL, ontologies
  • Familiarity with cross-domain data flow patterns
  • Infrastructure-as-Code (Terraform, CloudFormation)
  • Exposure to open-source data frameworks


👤 The Ideal Contractor

  • Operates independently with minimal oversight
  • Pragmatic, delivery-driven, and quality-focused
  • Excellent communication across technical & non-technical stakeholders
  • Strong analytical and problem-solving approach
  • Comfortable within structured delivery frameworks


🔒 Security Clearance

Candidates must be eligible for UK Security Clearance.

Some roles may require undergoing formal vetting during engagement.


💬 Ready to Make an Impact?

If you're a Senior Data Engineer who wants to work on meaningful, technically challenging projects that genuinely matter, this contract offers real depth, autonomy, and high-level engineering work.


If you want, I can also create:

✅ A punchier, shorter LinkedIn version

✅ A cinematic/military-style version

✅ A more corporate employer-brand version

✅ A version optimised for search (SEO)

✅ An outreach message version for direct candidate sourcing

Neurodiversity in Data Science Careers: Turning Different Thinking into a Superpower

Data science is all about turning messy, real-world information into decisions, products & insights. It sits at the crossroads of maths, coding, business & communication – which means it needs people who see patterns, ask unusual questions & challenge assumptions. That makes data science a natural fit for many neurodivergent people, including those with ADHD, autism & dyslexia. If you’re neurodivergent & thinking about a data science career, you might have heard comments like “you’re too distracted for complex analysis”, “too literal for stakeholder work” or “too disorganised for large projects”. In reality, the same traits that can make traditional environments difficult often line up beautifully with data science work. This guide is written for data science job seekers in the UK. We’ll explore: What neurodiversity means in a data science context How ADHD, autism & dyslexia strengths map to common data science roles Practical workplace adjustments you can request under UK law How to talk about your neurodivergence in applications & interviews By the end, you’ll have a clearer sense of where you might thrive in data science – & how to turn “different thinking” into a real career advantage.

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.
