- Ensure data is stored and retrieved correctly. Indeed+1
- Writing server-side code–business rules and data processing. Integrations with other systems. Indeed
- Collaboration with front-end engineers, UX engineers, and other stakeholders in order to deliver features.

- Junior backend developer / Entry level : Usually 0-2 year’s experience. You will support existing systems, repair bugs, and build parts of new features.
- Backend Developer, typically 2-5 years of experience. You will own key modules, create APIs, increase performance and work independently.
- Senior backend developer: Five years or more. You will architect system components, make technical decisions, and mentor others.
- Lead/Principal Backend Engineer : Responsible for technical architecture, strategy and design across multiple services.
- Specialised Backend Roles: E.g., API developer, micro-services engineer, cloud-backend (AWS/GCP), data-backend, etc.

- Database knowledge: SQL (MySQL and PostgreSQL), NoSQL databases (MongoDB and Redis)
- Ability to design and implement APIs. Indeed
- Cloud platforms: AWS, GCP, Azure, containers (Docker and Kubernetes), Micro-services architecture.
- Performance tuning, scaling of systems, and security best practices.
- Test-driven development (TDD), continuous integration/continuous deployment (CI/CD).
Soft Skills & Process
- Debugging complex systems and analysing failures are key to problem-solving. Indeed
- Communication and collaboration: You’ll collaborate with designers, front-end developers, product managers, and QA. Indeed
