Staff Data Engineer - AI Infrastructure Architect

BAO; Île-de-France; Hybrid; EUR 90,000 - 130,000; Full time

Job summary

BAO is seeking a Staff or Principal Data Engineer to shape the data architecture behind the next generation of AI. This deeply hands-on IC role combines software and data engineering with architectural leadership as the company scales, working across Data, Platform, Software and AI Engineering boundaries.

You'll own the technical direction for large data infrastructure areas, transform ambiguous data challenges into concrete architectures, and design scalable pipelines for ingesting, processing

Qualifications

• Deep software and data-engineering fundamentals.
• Strong track record of owning complex production systems end to end.
• Experience defining architecture across multiple systems or significant technical areas.
• Evidence of leading major technical work while remaining an individual contributor.

Responsibilities

• Own the technical direction for significant areas of our data infrastructure.
• Turn ambiguous data problems into clear architectures, systems and execution plans.
• Design scalable approaches to acquiring, ingesting, processing and integrating large datasets.
• Build and evolve infrastructure for data quality, sanitisation, security and privacy.
• Make architectural decisions around storage, processing, reliability, observability, scalability and cost.
• Identify where existing approaches will stop working and lead the move towards better ones.
• Establish patterns and systems that other engineers can build on, rather than solving each dataset independently.
• Work across Data, Platform, Software and AI Engineering boundaries to solve end-to-end problems.
• Provide technical direction to other engineers without needing formal line-management authority.
• Raise the engineering bar through design reviews, technical judgement and hands-on contribution.
• Stay close to code, production systems and debugging rather than becoming a purely architectural role.
• Use modern AI tools actively while applying strong engineering judgement to their output.
