Our Tech Team 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 the Product Experience Team, a cross-functional engineering group based in Barcelona and Nantes that owns the platform layer across all of Lengow’s product suites: channel execution (Netmarkets & Netamplify) and market intelligence (Netrivals & Net Monitor). We focus on solving the challenges that connect these suites, such as unified identity and access, self-service onboarding, cross-product analytics, and AI-powered features like compliance checks and category mapping. While other teams specialize in a single product, we work across all four, ensuring a cohesive and scalable platform. The team operates in a remote/hybrid model, values strong engineering practices, and delivers end-to-end features on a modern tech 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.

⌨️ Your main tasks would be as follows : • 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
