Senior Data Engineer
✨ About the role
We’re looking for a senior-level Data Engineer to join a high-impact media project at a very early stage. This is a unique opportunity to build an entire data ecosystem from the ground up in a fast-moving, low-structure environment where your technical decisions will directly shape the future of the platform.
The project focuses on integrating and reconciling data from multiple fragmented sources into a reliable, scalable, and business-ready foundation. We’re searching for a true “one-person army”, someone who can independently define architecture, establish best practices, build pipelines, communicate directly with stakeholders, and take full ownership of the data domain from day one.
The stack has not been finalized yet, which means you’ll have significant influence over tooling and technical direction. Strong autonomy, leadership, and communication skills are essential, as you’ll work closely with both technical and non-technical stakeholders.
🏠 Work setup
Our headquarters are based in Paris, while the engineering team works fully remotely.
⚡ What we value
Excellence in execution
Delivering high-quality technical and business solutions
Ownership, trust, honesty, and collaboration
Curiosity and continuous learning
Pragmatic decision-making with long-term thinking
✏️ Your responsibilities
Conduct discovery interviews with the client to understand their environment and business goals.
Propose and select the appropriate tools and technologies to build a Modern Data Stack from scratch.
Own the end-to-end design and implementation of the data infrastructure in a fragmented environment.
Build a production-grade data foundation ensuring reliability and scalability.
Integrate and reconcile multiple data sources such as CRM Batch, Piano, WordPress, and analytics tools.
Design and implement a robust data warehouse architecture aligned with business-critical use cases.
Develop and orchestrate resilient data pipelines using tools like Airbyte and SQL.
Define and implement a Master Data Management approach across inconsistent data sources.
Take full ownership of data quality including monitoring and validation processes.
Make and defend architecture decisions balancing speed and long-term sustainability.
Proactively communicate trade-offs and risks to both technical and non-technical stakeholders.
🎯 You’re the right candidate if you have
Proven ability to operate as a one-man army by talking to clients, picking the right tools, and delivering results without a pre-defined backlog.
4+ years of hands-on experience in data engineering within Modern Data Stack environments.
