At METRO, we are dedicated to advancing technology for one of the world's leading international food wholesalers. Our work spans e-commerce, checkout systems, and delivery software, focusing on building products that ensure daily success for our customers and colleagues. Through passion and a sense of ownership, we are actively shaping the future of the wholesale industry.

We are seeking a senior full stack engineer who possesses deep expertise across both frontend and backend technologies. The ideal candidate will have strong leadership capabilities, demonstrated experience in guiding architectural discussions, mentoring engineers, and driving technical excellence. This role requires proven experience in developing complex, distributed systems and workflow-driven architectures, including familiarity with technologies such as Camunda/CIB7, Istio, and microservices.

This role is integral to METRO’s global Quality Management System. As a Senior Full Stack Engineer / Tech Lead, you will play a crucial part in harmonizing and streamlining quality assurance processes across all METRO entities. You will contribute to a large-scale codebase that integrates backend services with a complex monolithic frontend. A key aspect of this role will involve guiding the transition towards modular, scalable components while maintaining reliability and design consistency. You will also be responsible for leading technical discussions, collaborating with architects, and mentoring fellow engineers.

Key Responsibilities

• Design, develop, and maintain both frontend (React, Redux, Material UI) and backend (Java, Spring Boot) components.
• Lead the modernization and modularization of a large monolithic frontend and backend codebase.
• Collaborate with architects and product managers on long-term technical strategies and system design.
• Mentor and support mid-level engineers, promoting knowledge sharing and high code quality.
• Ensure system performance, security, and scalability across frontend and backend layers.
• Champion clean code practices, automated testing, and CI/CD pipelines for development excellence.
• Work closely with DevOps and platform teams for cloud-native deployments on GCP using Kubernetes and Istio.
