Junior AI Engineer – Python, GenAI & Machine Learning (m/f)

Job Description & Summary

Join PwC Slovakia as a Junior AI Engineer, where you'll have the opportunity to grow your skills and contribute to AI and data science solutions for leading global clients. Our AI team is expanding rapidly — in the last 6 months alone, we’ve welcomed more than 20 new colleagues, and we’re continuing to grow. This role is not a replacement; we are scaling the team because we have a strong pipeline of AI projects. We are currently hiring across multiple seniority levels — from junior to senior engineers — as the demand for our AI solutions keeps increasing.

This role is designed for developers and engineers who want to build, integrate, and deploy machine learning systems and data-driven applications. We are looking for candidates who enjoy coding in Python, working with data, and turning ideas into reliable, scalable solutions.

Key Responsibilities:

• Project Participation: Participate in AI and data science projects from conception to deployment, contributing to solution design and supporting timely delivery of assigned tasks.

• Solution Development: Support the development of AI and ML solutions with a strong focus on Python-based implementation, working across areas such as Large Language Models (LLMs), RAG, classical machine learning and data analysis.

• Learning & Development: Continuously develop technical skills by following AI and data science trends, learning new approaches, and contributing to improvements of existing solutions and processes.

Who We're Looking For:

• Programming Skills (Key Requirement): Solid programming skills in Python (e.g. pandas, numpy, scikit-learn, plotly). Ability to write and understand code is essential. Experience with other programming languages is a plus.

• AI/ML Background: Hands‑on academic, project, or entry‑level experience with machine learning, data science, NLP, Computer Vision, or Generative AI (LLMs, RAG). The focus is on building or implementing solutions, not only using AI tools. Strong foundations in statistics and ML fundamentals are valued.

• Databases: Basic experience with SQL databases; familiarity with NoSQL databases is an advantage.

• Analytical Thinking: Strong analytical mindset with the ability to approach problems logically and creatively.

• Independence & Responsibility: Ability to work independently on assigned tasks and deliver results with guidance when needed.

• Language Skills: Fluent in English (B2 level or higher).

Projects you could be involved in:

• Natural Language Data Exploration: Develop dashboards powered by AI for intuitive business data analysis.

• Document Interaction: Design tools enabling seamless interaction with unstructured and structured text documents.

• Knowledge Assistant:  Implement ERP transformation with AI-powered tools to resolve employee inquiries efficiently.

• Agricultural Monitoring: Utilize Computer Vision for analyzing satellite imagery on a large scale.

• Automated Reconciliation: Create systems to identify anomalous transactions in accounting ledgers.
