#WePowerYourTalent

The energy transition happens through people who see their role beyond tasks and understand that what they do has a real impact.

At PPC, we contribute every day to a safer and cleaner energy system, from the networks that connect communities, to renewable energy that transforms the energy mix, or solutions that make electric mobility accessible.

Regardless of the role, our contribution is reflected every day in the communities we serve, in the customers who choose us, and in an energy system that is constantly evolving. We are present across the entire energy value chain and we are looking for motivated people to join us.

If you are curious to understand things in depth, responsible for seeing them through to completion, and open to working in a continuously changing environment, then your place is with us.

What you will do

In this role, you will have the opportunity to contribute to a purpose greater than daily tasks: making energy safer, more sustainable, and closer to people.

• Designing, building, and deploying machine learning models using Python and frameworks such as TensorFlow, PyTorch, ensuring models are robust, scalable, and optimized for performance.

• Utilizing SageMaker's built-in algorithms and tools to streamline workflows

• Developing and managing big data processing workflows using Apache Spark on AWS EMR. Optimize data processing tasks to handle large-scale datasets efficiently, enabling fast feature extraction and preprocessing for machine learning models.

• Utilizing Amazon Redshift and S3 for data storage, processing, and analysis

• Using MLFlow for experiment tracking, model management, and versioning, and ensure a systematic approach to deploying and monitoring models in production.

• Utilizing Apache Airflow to schedule and automate data processing tasks and model training workflows.

• Collaborating with data engineers to ensure seamless integration of ML models into production environments.

Experience Needed

We want you to join our journey with:

• Bachelor's or Master's degree in Computer Science, Data Science, Engineering, or a related technical field.

• 2+ years of experience in machine learning engineering, including demonstrated experience building and deploying machine learning models at scale.

• Strong programming expertise in Python and experience with Spark for distributed data processing.

• Hands-on experience with AWS services (EMR, SageMaker, Bedrock, Redshift, S3) for end-to-end machine learning pipelines.

• Ability to write clean, maintainable, and efficient production-level code, adhering to best practices in software engineering (e.g., version control, testing, CI/CD).

• Experience using MLFlow or similar tools for managing the machine learning lifecycle (model tracking, versioning, and governance).

• Familiarity with Apache Airflow (or equivalent tools) for managing and automating complex machine learning workflows.

• Strong analytical and problem-solving skills.

• Strong communication and collaboration skills.

• Good English knowledge (upper intermediate level).
