Experienced Fullstack Engineer - Store Apps

Empresa: MediaMarktSaturn
Provincia: Barcelona
Población: 
Descripción: Your Tasks We´re looking for an experienced Fullstack Engineer to join our Platform team; a small, high-impact team that boosts the effectiveness of three teams building our store experiences. You´ll be embedded in the centre of how we build and run software: owning shared infrastructure, shaping our backend orchestration service, and helping different teams move faster without sacrificing quality or reliability. Your Tasks Serve as a platform proxy for product teams: understanding their needs, unblocking them on shared concerns, and coordinating cross-team technical decisions. Contribute to our backend orchestration service used across all products: reviewing contributions, improving its design, and ensuring it remains reliable and well-documented as usage scales. Build and maintain shared projects such as the back office, taking ownership of both frontend and backend layers. Manage and improve our cloud infrastructure on GCP: provisioning, configuring, and maintaining environments used across product teams. Improve and extend our CI/CD pipelines (GitHub Actions), ensuring fast, stable, and repeatable delivery across all teams. Strengthen our observability: setting up and refining monitoring, alerting, and dashboards with Grafana to give teams clear visibility into production health. Write clean, well-tested code and contribute to a culture where quality and reliability are default. Support and mentor engineers across product teams, sharing knowledge on platform practices, infrastructure, and architectural patterns. Your Profile Solid fullstack experience with TypeScript and Node.js. You´ve shipped and maintained production services and are comfortable owning them end-to-end. Frontend capability in React. You can build and maintain interfaces without needing a dedicated frontend team to carry you. ReactNative experience is a plus. Strong grasp of GraphQL for API design and data querying; experience with Apollo is a plus. Hands-on experience with MongoDB: schema design, indexing strategies, and query optimisation at scale. Comfortable with GCP services and Terraform for infrastructure-as-code; you understand how cloud environments are structured and managed. Experience with CI/CD tooling, particularly GitHub Actions: you can build and maintain pipelines that teams actually trust. Familiarity with event-driven architectures using Google Pub/Sub or similar systems; you understand the trade-offs between synchronous and asynchronous patterns. Experience with Grafana (or equivalent): you think about observability as part of building, not as an afterthought. A solid testing discipline covering unit, integration, and end-to-end scenarios; you think about failure modes and edge cases from the start. Strong communication skills and a collaborative mindset: you can work across team boundaries, synthesise input from multiple stakeholders, and make pragmatic decisions.
