- 1 year of mission (renewable)
- Location: Luxembourg (60-70 %) - Frankfort (30-40%)

Responsabilities
- The system architect defines the target architecture for a banking application/functional area and ensures it is fit for its intended purpose while being compliant with architecture standards.
- The system architect is responsible for all applications across the full lifecycle in his area and looks at all aspects from business architecture down to infrastructure architecture.
System architecture:
- Gain direct influence on the business vision by shaping the target architecture alongside product management and key stakeholders, ensuring your architectural decisions clearly translate into real business outcomes
- Own end-to-end architectural design, giving you full accountability for technical coherence, long-term scalability, and design quality
- Drive clarity and alignment by translating strategy into a concrete solution intent, with a visible roadmap, clear information models, and explicit dependencies that make complexity manageable
- Build systems that scale by defining clear subsystem boundaries and interfaces, enabling cleaner integrations, easier deployments, and fewer downstream surprises
- Anticipate future needs by designing and evolving the architectural runway, allowing teams to deliver new features faster without constant rework
- Operate in a sustainable environment where architectural standards protect system stability, long-term maintainability, and technical credibility
- Reduce long-term workload and operational risk by actively controlling application lifecycle and architectural debt, with transparency and the authority to prevent short-term trade-offs from becoming long-term problems
Planning:
- Work at system and enterprise level to shape architectural approaches and capability roadmaps, giving you visibility and impact beyond a single product or team
- Influence quarterly priorities by contributing directly to Qbrs and PI objectives, ensuring technical enablers are planned early rather than treated as afterthoughts
- Create alignment across teams by consolidating technical insights into clear, shared PI objectives that reduce friction and conflicting directions
- Enable teams to deliver effectively by helping structure features and stories in a way that preserves architectural intent while remaining execution-ready
Collaboration:
- Act as a technical reference point by identifying risks between standards and innovation, and actively shaping robust, bank-wide architectural solutions
- Strengthen decision-making by aligning stakeholders, customers, and partners around a shared architectural direction that supports both system intent and business priorities
- Gain hands-on exposure to supplier ecosystems by ensuring externally delivered solutions integrate cleanly, with full control over technical quality and system consistency
