Key responsibilities:
You will work as a “full stack” data scientist, taking projects from problem formulation to production, independently, as part of a team, or as the team lead.
Understand and translate business problems into smart, pragmatic, high-quality Python solutions that leverage quantitative, data-driven techniques.
Define and run targeted analysis and experiments to reduce uncertainty before initiating long-term projects and critically evaluating the available options.
Exemplify and demonstrate best-practice data science and machine learning across the business and ensure models are re-usable and continuously improved.
Design and implement scalable, reliable data pipelines that ingest, process, and deliver high-quality data to downstream applications.
Enable in-production monitoring of data science and ML solutions.
Design, guide and support data validation and quality assurance activities to assure and improve the robustness and quality of datasets.
Author and maintain methodologies and client-facing documentation, and present results and recommendations clearly, succinctly, and honestly to a variety of audiences.
Understand and maintain existing codebases and system architectures, as well as develop solutions from scratch.
Collaborate with stakeholders, product owners, designers, analysts and other data scientists to design solutions which make sure our clients’ needs are met and the best technical solutions are adopted.
Skills and experience required:
Strong background in data science, computer science, applied mathematics, statistics, or another quantitative field.
Proficient / intermediate level programming skills in Python.
Experience using foundational Python data science libraries (e.g. pandas, numpy, scikit-learn, …).
Experience with SQL and working with databases like Postgres and Snowflake.
Experience of working within cloud environments (Azure and AWS preferred).
Comfortable with sourcing, cleaning, transforming, analysing and visualising data of wide range of types, volumes and quality.
Confident with diverse techniques for testing your code.
Track record of working as part of a data science or similar team and successfully delivering end-to-end analytics/ML/data science solutions in a commercial setting.
A highly motivated, inquisitive, customer-centric collaborator, with a willingness to learn new technologies and ways of working, who demonstrates a “let’s do it” and “challenge accepted” attitude when faced with less well-known or challenging tasks.
A data-driven approach to make development decisions based on robust analyses.
Motivation to explore diverse and potentially unknown techniques. Ability to propose creative, efficient, and effective solutions to new types of problems.
Ability to communicate clearly and concisely at all seniority levels, with both technical and non-technical audience.
Desirable skills include:
Knowledge of Infra-as-code (Terraform), CI/CD pipelines, and Kubernetes, software collaboration experience using version control, preferably Git. Experience using software development / deployment tools, platforms, and best practices e.g., CI/CD pipelines, and containerization technology. Experience with AI-related technologies and products.
