Data Engineer : 5 employeurs, un intitulé

We’re looking for a Senior Data Engineer to join our Engineering & Data team. In this role, you’ll be responsible for a wide array of topics such as: - Build and operate robust data pipelines that keep pace with ever-evolving business needs, ensuring the architecture supports them cleanly. - Contribute to the codebase, ship and maintain your changes in production, and champion strong coding and data engineering practices. - Use AI coding tools (Claude Code, Codex, and whatever comes next) as a core part of your daily workflow — to move faster on pipelines, migrations, tests and documentation — while staying fully accountable for what you merge. [...]

Our ML teams train models on datasets derived from large volumes of raw, unstructured data. Model quality depends directly on data quality, and today that data is handled largely by hand. As a Data Engineer, operating out of Paris, Lausanne, or Zurich, you will own the data layer that feeds the team's models, from raw field logs or public datasets through curated, versioned, training-ready datasets. You will manage terabytes of raw, unstructured data and turn it into clean, documented, versioned datasets, so that the modelers spend their time designing and training models, not waiting on data loaders or wrangling corrupted files. [...]

- Build and maintain batch and streaming data pipelines. - Move production data into archival/data lake storage safely and observably. - Improve quality, reliability, and observability of derived datasets. - Design validations for freshness, completeness, schema correctness, and data quality. - Build reusable datasets that reduce one-off data extraction and aggregation work. - Optimize queries and data processing jobs for correctness, latency, and cost. - Prototype in the right tools, then integrate scoped production experiments with amo’s systems where needed.

We’ve built BeReal with a tiny technology team of world-class engineers and we intend to keep this mindset as we scale it to hundreds of millions of users. To achieve this, we ship new features faster than any other scaled social network while upgrading our infrastructure. We work in small teams of generalists and give each engineer high autonomy to make product related decisions. - Construct and manage robust data pipelines to align with ever-evolving business needs, ensuring optimal architecture support. - Contribute to the codebase, push and maintain your changes in production, and be an evangelist of good coding and data engineering practices [...]
