## Description

You will work in multidisciplinary teams alongside proposition managers, journey experts, UX/UI designers, data analysts, developers, architects, business analysts, and product owners. Together, you will drive impact end-to-end: from defining the right customer problem to experimenting, building, launching, and continuously improving solutions. We value speed, ownership, and action-turning insights into tangible results without unnecessary delays.
Your Role
As a Back-end Developer, you are responsible for delivering the core functionalities that power navigation, profiles, and the overall app experience. You ensure that customers can effortlessly find what they need and move intuitively through the app.

You will:
Design, build, and maintain robust and scalable back-end services
Develop and manage APIs that support navigation, profiles, and core app features
Ensure a consistent and future-proof navigation architecture
Conduct discovery work to better understand customer needs and technical constraints
Collaborate closely with front-end teams, platform engineers, and other stakeholders
Contribute to a seamless and intuitive overall app experience by aligning backend capabilities with user journeys
Continuously improve systems based on performance data and feedback
This is a core back-end engineering role focused on building reliable, scalable systems-not an AI-focused position.
Your Profile
You are a pragmatic and fast-moving engineer who thrives in a dynamic environment. You know how to balance speed with quality and understand when to reuse existing solutions versus building new ones.
