This investment will enhance scalability and maintainability, reflecting iwoca's growth and modern approach to business loans.
• Implement new customer offer display interfaces: Develop and maintain user interfaces that allow customers to interact with and customise their loan offers. This includes building and integrating features and tools that maximise the utility of our products.
• Develop robust analytics infrastructure: Build and enhance data models and pipelines to ensure accurate and timely data collections. This will involve designing and implementing data solutions that empower the strategy and analytics team to conduct split tests and make data-driven decisions.
  • Proficiency in Python with a strong background in back-end engineering.
  • Experience designing, building, and managing relational databases.
  • Experience designing, building, and maintaining API endpoints.
  • Confidence working across the full stack, including front-end development in React/TypeScript, with a desire to learn new technologies.
  • Strong communication skills, with the ability to translate business needs into clear, effective technical solutions.

Bonus

• Experience with Django and PostgreSQL
• Experience with design software, such as Figma

• A strong numerical or technical background, with a degree in maths, physics, computer science, engineering, or relevant industry experience
