Role overview
As a Full Stack Software Engineer at QLC, you will help develop and scale the QLC Portal and adjacent internal tools. You will work closely with product, operations, and colleagues across the business to turn practical requirements into reliable software. This is a role for someone who can both build and communicate: write sound code, explain decisions clearly, ask sensible questions, and work productively with others.
How we use AI
We use AI-assisted development tools where they genuinely improve speed or quality. The useful skill is not blind reliance. It is the ability to frame problems precisely, test output critically, and apply judgement.
Key responsibilities
- Collaborate with product and internal stakeholders to design, build, and ship new features for the QLC Portal and internal software systems.
- Develop and maintain frontend and backend components using modern frameworks and tools.
- Translate product requirements into clear technical decisions and practical implementation plans.
- Optimise the platform for performance, reliability, usability, and scalability.
- Write clean, maintainable, and testable code that aligns with shared engineering standards.
- Troubleshoot, debug, and resolve technical issues with clear communication throughout the process.
- Contribute to architecture and process decisions so the platform remains secure, efficient, and adaptable.
- Use AI-assisted tools sensibly to support research, prototyping, debugging, and routine implementation work.
- Stay up to date with relevant technologies and working practices, and contribute ideas that improve the product and the development workflow.

- Communication and working style
- Clear written and verbal communication.
