• Working in Python with libraries such as Scikit-learn and TensorFlow for model deployment
• Deploying and optimising services on cloud platforms such as Azure or AWS
• Supporting end-to-end product development alongside architects and stakeholders

The skills you will need:

This is a role for someone already comfortable with applied data and machine learning systems, who can also build, ship and maintain clean, maintainable backend applications.

Required:

• 3 or more years of experience as a full stack developer
• Experience building and consuming REST APIs
• Proven hands-on experience with data analytics and production-grade ML or AI tooling
• Experience developing integrations across systems and services
• Strong knowledge of both SQL and NoSQL databases
• Python as a primary language, including libraries such as Scikit-learn or TensorFlow
• Exposure to cloud platforms such as Azure or AWS
• Familiarity with Git and code repository tools

Desirable:

• Experience in enterprise-scale environments
• Knowledge of Java in addition to Python
• Background in data engineering or predictive insight tooling

Personal qualities:

This role suits a developer who thrives on solving complex data challenges. You will enjoy working across services, code and models to build intelligent systems that deliver practical results.
