• Experience with data lakes, table/storage formats, and derived datasets.

Responsabilités

• 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.

Life at amo

To ensure that everyone is set up for success within our way of working, we work together onsite 5 days a week.

We wanted to make sure coming to the office was as comfortable as possible for you:

• We chose a location in central Paris, near Opera (Metro lines 3,8,9 and RER A).

• We have a beautiful Parisian-style office with high ceilings, balconies, and huge windows. So a lot of natural light!

Because life outside of work should also be stress-free, we cover:

• Health care (100% coverage).

• Maternity Leave, Paternity Leave, Second Parent Leave (salary maintained at 100%).

• Vacation days: 8-9 weeks (total) per year - (European summer? ).

  • 5 weeks of paid time off (by the state);

  • 1-2 additional weeks (RTT, based on our company contract);

  • ~11 bank holidays.

    We shut down entirely twice a year, two weeks in summer and one week in winter to allow everyone to truly recharge and to avoid prolonged slowdowns (especially in the summer). These pauses are part of your total vacation time, giving everyone a real chance to unplug and recharge. No Slack, no email, no FOMO.
