Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Data Scientist - **Company:** BigHand - **Location:** London, UK (Remote available) - **Contract:** Permanent contract - **Skills:** Data Analysis, Systems Engineering, Code Review, Continuous Delivery, Corona (Software Development Kit), Human-Computer Interaction, Python (Programming Language), Machine Learning, NumPy, Software Deployment, Data Processing, Large Language Models, Pandas, Scikit Learn - **Published:** August 25, 2026 - **Apply:** https://uk.indeed.com/viewjob?jk=e630d928ae978aba ## About the Role * An analytical background, evidenced by a STEM degree in a technical subject. Physical sciences or mathematics are preferred. * Strong Python skills and competency across the Python data science ecosystem such as pandas, numpy and scikit-learn, or a highly transferable equivalent. * Experience working with LLMs and agentic AI systems, including harnesses, RAG, context engineering and evaluations. * Experience working safely and efficiently with agentic engineering systems. * Solid experience with data wrangling and data analysis. * The ability to train, tune and evaluate models and prepare them for production deployment. * A solid understanding of modern software development lifecycle practices. * The ability to navigate typical problems independently, contribute to discussion and help shape technical requirements. * The ability to communicate complex statistical and machine learning concepts and their results clearly, including to non-technical audiences. Desirable * An insatiable appetite for learning and for acquiring new knowledge, skills and experience. * Comfort operating independently on both existing and new systems while preserving and improving a consistent project structure. * A positive force in building the team as we grow and develop into more senior positions. * A habit of introducing new technology and practices that accelerate the team, for example through lunch and learn sessions. * Experience in the legal industry or another regulated environment such as health or financial services. ## Description BigHand builds software that legal organisations rely on every day. We are looking for a Data Scientist to help us design and ship products to establish our partnership with Ayora, where a clean, considered user interface meets genuinely intelligent behaviour underneath. This is a hands-on role for a data scientist who wants their work in production rather than in a notebook. You will build and evaluate the models and LLM systems that sit behind the product, contribute to how problems are framed as well as how they are solved, and take real ownership of the quality of what we release. What you'll do * Train, tune and evaluate models, and prepare them for production deployment alongside engineering. * Build and improve LLM and agentic AI systems, including harnesses, retrieval augmented generation, context engineering and evaluation frameworks. * Wrangle and analyse messy real-world legal data, and turn it into something the product can rely on. * Design evaluations that tell us honestly whether a model or agent is working, and act on what they show. * Explain complex statistical and machine learning concepts and results clearly, through visualisation and summarisation, including to non-technical audiences. * Contribute to technical discussion and help refine requirements rather than simply consuming them. * Deliver consistently within a collaborative agile framework, with a track record of predictable, high quality output. * Develop well-constructed solutions using the best tools available, avoiding fragile shortcuts taken for short-term speed or to sidestep discussion. * Apply modern software development lifecycle practices, including code review, testing and continuous delivery. ## Related Videos - [Are Code Reviews Worth It?
