Data Scientist (Contract) – AI/NLP for Cleared Defence Deployment

Contract | Inside IR35 | £600–£700/day | Hybrid / Secure Site | SC/DV Cleared | UK Nationals Only

Contract Length: Initial 3-month engagement (rolling), forming part of a 6–9 month delivery track

We've partnered with a fast-paced UK-based AI software company delivering a major MOD-backed programme. They're developing a mission-critical AI capability for deployment in a secure environment, and they're looking for data scientists who excel in tackling complex challenges.

This is high-impact work, constrained by real-world operational, compute, and security boundaries and delivered as part of a small, elite, cross-functional team.

What You’ll Be Doing:

  • Designing and implementing NLP pipelines for transcription, topic extraction, and summarisation

  • Developing modular LLM workflows (e.g., RAG, graph-based reasoning) optimised for low-resource deployments

  • Integrating structured and unstructured data: transcripts, policy documents, supply chain models

  • Collaborating with platform engineers to containerise models for edge inference

  • Defining evaluation frameworks using both metrics and human-in-the-loop feedback

  • Supporting secure deployment across classification levels and offline environments

  • Participating in on-site trials, tuning performance and refining capability under pressure

  • Ensuring alignment of AI output with operational decision-making requirements

    What You’ll Bring:

  • Hands-on experience building and deploying NLP/LLM solutions, including summarisation, entity extraction, and topic modelling

  • Strong Python skills with libraries such as HuggingFace Transformers, spaCy, PyTorch/TensorFlow, or RAG frameworks

  • Experience with knowledge graphs, GNNs, or graph-enabled retrieval

  • Proven ability to optimise ML systems for air-gapped, low-compute, or edge environments

  • Understanding of evaluation methods using SME and human review cycles

  • (Bonus) Prior work in Defence, aerospace, or similarly secure/regulated domains

    Why This Project?

    You’ll be shaping how NLP and LLMs are deployed into critical operational settings, where the constraints are real but so is the impact. It’s an opportunity to build novel, mission-relevant ML capability that won’t just sit on a shelf.

    Interested?
    If you’re cleared, available within 2–3 weeks, and excited to bring AI to life in Defence - we want to hear from you

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.
