Desirable

• The Tech, Data, and Product team comprises 70+ people from diverse backgrounds, working in our offices in Nantes, Paris, and Barcelona. Our products are developed thanks to six autonomous product Teams, each working on a specific business domain. The teams are led by a Product Manager and Engineer manager working with a dedicated small team of developers (from 4 to 8)
• You’ll be joining a cross-functional engineering team in Barcelona with full ownership across two internal platforms: channel execution (Netmarkets & Netamplify) and market intelligence (Netrivals & Net Monitor). The team operates in a remote/hybrid model, values engineering craft, and ships features end-to-end across a modern stack
• The stack includes PHP/Symfony, React, PostgreSQL, MariaDB, GCP, Kubernetes, RabbitMQ, and Datadog — with an active push toward AI-augmented development workflows
• As we continue to scale and unify both platforms, we need a strong full-stack engineer who can take ownership of complex backend features while collaborating effectively on the frontend. You’ll be a key contributor in a team that values clean code, pragmatic architecture, and cross-functional impact
• Design, build, and maintain backend services and APIs in PHP/Symfony across both platforms
• Own database schema design, query optimization, and migration strategies in PostgreSQL/MariaDB
• Contribute to React-based frontends — reviewing, implementing, and improving UI features
• Collaborate on architectural decisions and participate actively in code reviews
• Operate and deploy services in a Kubernetes/GCP environment, maintaining observability with Datadog
• Work closely with product managers, designers, and peer engineers in an agile setup
• Leverage AI-assisted development tools (GitHub Copilot, Claude, Gemini) as part of your daily workflow
