Job Specifications
This mid-level data science role is based within a cross-functional delivery team, working on our groundbreaking genAI product. The successful applicant will be crucial in collaboratively researching/modelling/building features to personalise and power intelligent user interactions.
Your responsibilities will include hands-on product development, adherence to industry best practices, including model development and deployment, and the use of techniques such as reinforcement learning to improve product performance.
You will have solid foundations in machine learning theory and practical experience, particularly in NLP, is essential for success. We are also looking to push the performance boundaries of our new product as far as possible, so experience and knowledge of techniques like reinforcement learning would be a bonus.
You will need to be confident in writing production-ready Python code, building end-to-end functionality, and deploying it to a live environment. Experience working within a professional software development setting is essential.
Responsibilities
Develop, train, and deploy machine learning and AI models, with a focus on NLP and language understanding tasks
Write production-grade Python code to build functionality and deploy AI systems to production
Work extensively with PyTorch and other machine learning frameworks to build and iterate on models
Optimise and productionise models inside the AWS ecosystem, using accelerated hardware resources where needed
Build intelligent guardrails to protect our users, product and customers
Collaborate closely with cross-functional teams, including other data scientists, product and machine learning engineers, to integrate AI solutions into our tech stack
Explore and implement cutting-edge techniques like reinforcement learning and LLM fine-tuning
Explore and implement methods to measure product performance and gain insights into performance metrics
Documentation and active knowledge sharing
Cross-functional team collaboration
Adherence to best practices, including code quality and security
Continuous learning and development
Responding to alerts from monitoring systems on models or technology in the data science domain (during work hours)
Requirements
Experience in data science and machine learning, with a proven track record of deploying models in production settings
Proficiency in writing production-grade Python
Familiarity with machine learning and deep learning frameworks (e.g. Scikit-learn, PyTorch, TensorFlow)
Experience with web development frameworks (Django, FastAPI)
Experience with containerisation technologies (e.g., Docker, ECR) and an understanding of GPU acceleration for deep learning
Experience working in a software engineering environment
Experience with microservice design patterns
Experience in a range of machine learning techniques, such as:
NLP techniques like text embeddings, large language models and entity & intent recognition
Reinforcement learning algorithms and applications
Recommendation techniques and algorithms
Supervised and unsupervised machine learning techniques
Prediction and uplift modelling techniques
Experience with agentic, RAG, required; council orchestration understanding, beneficial
Previous exposure to sales funnel optimisation, sales and marketing insights, sales psychology and its application in data-driven contexts is beneficial
Excellent communication skills, with the ability to clearly articulate technical concepts to non-technical stakeholders
Studies have shown that women and people who are disabled, LGBTQ+, neurodiverse or from ethnic minority backgrounds are less likely to apply for jobs unless they meet every single qualification and criteria.
