## POSITION

- A Senior Fullstack Engineer (AI-Native) builds production-grade applications and intelligent workflows with an AI-first mindset across the full software development lifecycle. This role is for an engineer who does not treat AI as an add-on, but as a core way of working across design, implementation, testing, documentation, debugging, and delivery.
- The ideal candidate consistently approaches work by asking whether a task can be completed entirely with AI or materially improved through AI-assisted execution, while still applying strong engineering judgment and quality controls.

## CHALLENGE

- Full-Stack Engineering: Design, build, and maintain scalable applications using Java (backend).
- AI-Native Product Development: Integrate GenAI APIs and LLM-powered capabilities into core product workflows. Build agentic flows, tool-using systems, and AI workflow automations with clear guardrails and observability.
- AI-Native Engineering Practice: Apply AI-assisted workflows across the full SDLC - from design and implementation to testing, debugging, and documentation. Review and validate AI-generated outputs for correctness, security, and production readiness.
- Technical Leadership: Drive architectural decisions, mentor engineers, and champion AI-native engineering practices across the team.

FOR THIS EXCITING MISSION YOU ARE EQUIPPED WITH...

- 6+ years of professional full-stack engineering experience across frontend, backend, APIs, databases, and production systems, with strong end-to-end ownership of product delivery.
- Strong backend development skills in Java and/or Python, with solid understanding of system architecture, scalability, and production reliability.
- Experience integrating GenAI APIs, LLM features, assistants, or AI-powered product capabilities into production systems.
- Immersive adoption of AI across the SDLC. Demonstrated experience using AI-assisted development workflows for scaffolding, refactoring, testing, debugging, documentation, and delivery while critically reviewing outputs and maintaining engineering standards.
- AI-first mindset. Approaches every task by asking whether it can be completed entirely with AI or improved significantly through AI, then applies the right level of human review, validation, and control.
- Excellent communication skills and fluency in English to collaborate effectively in an international environment.

## PERSPECTIVE

Access to a global network of a globally united and mutually responsible “Tribe of Intrapreneurs” that is passionately dedicated to renew the travel industry and while doing so reinvent the ways how businesses stay, work and pay.

Our entrepreneurial driven environment of full ownership and execution focus offers you the playground to contribute to a greater mission, while growing personally and professionally throughout this unique journey. You will continuously learn from a radical culture of retrospectives and continuous improvement and actively contribute to making business life better, smarter and more sustainable.

LOCATION, MOBILITY, INCENTIVE
