As a Full Stack Engineer in the Commercial Intelligence Value Stream, you will turn business needs and improvement ideas into useful internal products, tools and applications. You will work with business and technical stakeholders to understand how people work today, identify where AI and automation can help, and rapidly deliver solutions that create value.
The potential projects are varied and will evolve over time. It may include web applications, lightweight APIs, decision-support tools, integrations with existing systems, and user interfaces for data or analytical capabilities. The focus is on pragmatic internal solutions that improve efficiency, speed to market and decision quality, rather than on a single predefined product or technology pattern.
You will own work end to end: discovery with users, technical shaping, prototyping, implementation, release, feedback and iteration. Success means shipping useful products quickly, learning from real users and evolving the right solutions while working within Eurowings Digital technology standards.

- Experience modernising or replacing off-the-shelf or legacy internal tools through close collaboration with users.
- Knowledge of airline or other data-intensive commercial environments.
What you will bring
- An ownership mindset and the confidence to take a problem from first conversation to a working product.
- Curiosity about how teams operate and the ability to build trust with business users and technical specialists.
- A bias towards action, rapid learning and visible value, without losing sight of security, reliability and agreed technology standards.
- Flexibility and open-mindedness about the right solution, whether that is a polished web application, a lightweight API, an integration or an improvement to an existing tool.
- Clear communication, proactive expectation management and the ability to explain technical trade-offs in business terms.
- A continuous-improvement mindset and willingness to share knowledge, seek feedback and strengthen engineering practices.
