Frontend-heavy fullstack role. You will be working within the **Optimal Choice squad**, owner of the backoffice tool "Delivery Areas Service" that determines which vendors deliver to which customers. Due to it being an old tool based on outdated technologies and intertwined code, the squad has been historically prevented from pursuing the long-term vision for it and providing the functionalities that our users long for. Until now. You will be joining the squad at an important milestone in its 10-year history: we are migrating the tool to a more secure internal system and way of deployment. While doing that, we are redesigning the application from scratch, aiming at better UX, better guardrails and better development experience. You will work closely with the design team in building what is, in fact, a complete new application. You will also be leveraging the already company-integrated state-of-the-art AI agentic tools to support you in this work in what will very likely be a gratifying, fun and interesting experience. By leveraging your fullstack skills, you will also have the opportunity and autonomy to deliver functionalities end-to-end, build on your backend experience in Python and become a pillar of the domain and solidify your position as a person who knows the system inside-and-out. In our Logistics Team, you'll tackle high-impact challenges that make last-mile delivery efficient, affordable, and sustainable. Your work will directly improve experiences for riders, end customers, and merchants across the globe. Each enhancement you contribute will help Delivery Hero optimize delivery operations, supporting expansion into new areas like grocery and retail. - **Lead the Migration**: Drive the end-to-end rewrite of our existing back-office tools into the new Ops Portal, eliminating technical debt and implementing modern design specifications. - **Build from Scratch:** Leverage modern React and updated libraries to create a high-performance, analytical tool that provides a superior experience for our internal users. - **Bridge the Stack:** While leaning heavily into the frontend, you will also ensure seamless integration with our Python-based microservice, performing necessary adjustments for a successful end-to-end data flow. - **Collaborate & Mentor:** Partner closely with our frontend specialist, to elevate the team's frontend ecosystem and mentor other engineers on best practices. - **Own the Lifecycle:** Take full ownership of features from initial specification and system design to deployment and production monitoring. **Qualifications** - **Frontend-First Mindset:** You identify as 80-90% Frontend-focused. You are an expert in modern React (Hooks, Context, State management) and are happy to leave legacy Redux patterns behind. - **Backend Capable:** You are "Fullstack-literate." You have experience with, or a strong ability to debug and contribute to Python backends and write efficient SQL queries. - **Autonomous & Pragmatic:** You have 5+ years of experience and a track record of delivering functionality with minimal bugs. You know how to balance "perfect" code with the need to ship value. - **Architectural Fluency:** You understand component-driven architecture and can contribute to system design discussions that span across multiple services. - **Testing Rigor:** You believe in the "test-pyramid" and write robust unit and integration tests to prevent regressions in our new codebase. - Problem Solver: You don't just move tickets; you look at the business impact of delivery area dynamics and suggest technical solutions to improve the logistics' efficiency, help prioritize those solutions and collaborate well with your team members to deliver them . - AI Adopter: You lean in to the age of AI-tools and know how to leverage them to get your work done in an efficient way **Additional Information** Ensuring you and all our Heroes are looked after, happy, and healthy is always on the menu.
