La IA no eliminó la ingeniería de datos. La hizo más necesaria, porque cada modelo necesita datos limpios y gobernados.

Quién sufrió los despidos

Sobre todo los perfiles que solo hacían informes. Quien mantiene pipelines, almacenes y costes en la nube siguió contratado.

Cómo debe verse tu CV

  • Una columna y una página.
  • Cada punto con una cifra concreta.
  • Tres proyectos en GitHub con diagrama y README.

Cursos gratis

NVIDIA DLI, Google Cloud Skills Boost, Microsoft Learn (DP-900 y DP-700), Databricks Academy y DE Zoomcamp.

Prácticas

Postula entre agosto y octubre, haz una pregunta técnica concreta antes de pedir una referencia y mira empresas fintech y de logística.

Cómo funciona un centro de datos

Perspective view down a cold aisle between two rows of server racks with blue and green status LEDs, raised floor tiles, overhead cable trays and cooling ducts. COLD AISLE · GPU RACKS · ZUBAIRHUSSAIN.XYZ
Cold aisle between two rows of racks. Cold air comes up through the perforated floor; servers exhaust heat into the hot aisle behind them.
Grid power passes through substation, UPS batteries and generators to power distribution units feeding the racks. Chillers and cooling towers feed CRAH units that push cold air through the aisles.
