    Write high-quality, scalable code in line with established engineering standards and best practices

  • Collaborate with stakeholders to identify problem areas and implement solutions, including frontend interfaces, data integrations, and third-party service orchestration, with a focus on reliability and resilience

  • Work closely with Data Engineers, Data Scientists, and Software Engineers across the Lifecycle and Online Marketing teams


 


You’ll be great for this position if you have:



  • 3+ years of experience in full-stack software development, ideally with exposure to Go and Python

  • Hands-on experience building web user interfaces using TypeScript or JavaScript, along with designing and consuming RESTful APIs in a microservice-based environment

  • Experience working with SQL and event-driven architectures, including practical experience with PostgreSQL and Kafka

  • Familiarity with building solutions that leverage generative models, alongside a solid understanding of system architecture, software design principles, data modelling, and API design

  • A collaborative approach to working in cross-functional teams, with openness to feedback and continuous improvement

  • Strong sense of ownership and responsibility for delivering high-quality, well-engineered solutions

  • Clear and effective verbal and written communication skills, with experience engaging and collaborating with stakeholders
