Ai engineer

Join us at NOS as AI Engineer

At NOS, we are applying Generative AI and Machine Learning in large-scale internal operations, with a clear goal: to transform the organization's operating model and measurably improve the daily lives of thousands of employees and millions of customers.

We are a future-oriented company, a leader in communications, entertainment, and technology in Portugal. We believe in the power of innovation to create real impact — economic, social, and environmental — and we are bringing GenAI into production, not just for pilots. This role is for those who enjoy building real systems used every day: production integrations, clear metrics, incidents, continuous learning — and not just demos or proofs of concept. You will work in agile, multidisciplinary squads, connecting GenAI + data pipelines + software engineering, mainly in GCP, with a direct impact on NOS's internal operations.

Your day-to-day (GenAI-first)

The typical distribution of work will be close to:

• ~60% GenAI
• ~25% Data Engineering
• ~15% classical ML

Stack and architecture (indicative)

• Cloud: GCP (BigQuery, GCS, Pub/Sub, Cloud Run; others as needed)
• Language: Python

How we measure success at NOS

• GenAI solutions that reduce operational time and costs, with clear metrics

Who we are looking for - Must-have (to proceed)

• Practical experience delivering data/ML software in production (or equivalent experience; Master's valued but not mandatory)
• Solid Python (readable, testable, versioned code; comfort with code review)

Why NOS?

• Real scale, complex data, and relevant problems
• Experienced teams in engineering, data, and product
