Job Title: Data Scientist - NLP, LLMs & Generative AI
Are you passionate about leveraging AI to solve real-world business challenges? We're looking for a talented Data Scientist to join a growing and forward-thinking data science function focused on driving innovation through NLP, large language models (LLMs), and generative AI.
This is an exciting opportunity to be part of a newly established team, working closely with the Head of Data Science to shape the roadmap, scale AI-driven solutions, and unlock new opportunities across the business. If you're hands-on with Python, experienced in building NLP or LLM-based applications, and thrive in a collaborative, problem-solving environment-this role is for you.
What You'll Do:
Design and deploy AI-powered tools that streamline internal processes and drive growth
Apply advanced NLP, LLMs, and automation techniques to enhance workflows and insights
Identify AI use cases with cross-functional teams and deliver practical, impactful solutions
Experiment with emerging open-source LLMs and generative AI technologies for adoption
Develop RAG (Retrieval-Augmented Generation) pipelines for extracting insights from unstructured data (PDFs, images, emails, etc.)
Support proof-of-concept development and help scale successful solutions across the business
What We're Looking For:
Technical Expertise:
5+ years of hands-on experience with Python for machine learning and data science
Strong background in ML, NLP, and LLMs, including training/fine-tuning models (e.g., Transformers, encoder-decoder architectures)
Experience with open-source LLMs (e.g., LLaMA, Mistral, DeepSeek, Qwen, etc.)
Familiarity with Hugging Face Transformers and related NLP libraries
Experience building RAG pipelines with embedding models and vector search
Application Development:
Comfortable developing APIs using FastAPI or Flask
Experience with tools like Streamlit or Gradio for building interactive AI applications
Demonstrated ability to integrate LLMs into real-world applications
Infrastructure & Deployment:
Experience testing models on local GPU infrastructure
Knowledge of Python environment management and containerization (Docker is a plus)
Data & Version Control:
Proficient with Git for collaborative development
Ability to access and process structured and unstructured data (e.g., SQL, PDFs, images, emails, JSON)

Frequently asked questions
Why should you trust a specialist technical recruitment agency to find you your next role?
Using a specialist recruitment agency like Matchtech to find your next role is a smart move for a number of reasons. One of the main advantages is that it's a good way to cast your job searching net out wide. Recruiters often have a number of similar positions on the go with different clients, so if you're unsuccessful with one position, you can be put forward for many other vacancies at the same time, increasing the likelihood of you landing your dream job faster and with a lot less effort.
Does Matchtech take a cut of my pay if I use them to find my next job?
Absolutely not! We charge the end client for our services, not the candidate. So you can rest assured that there is no difference to your pay when being placed into a new role by Matchtech.
If I use a recruiter at Matchtech to find my next role, am I going to be bombarded with irrelevant job opportunities?
