Overview

Senior Machine Learning Engineer (d/f/m) at Personio. Hybrid role based in Dublin, London, or Munich office 2 days a week.

Role Responsibilities

  • Design, develop, and deploy robust machine learning and AI systems for a range of products and use cases, including generative AI.
  • Integrate ML and AI models into production systems, ensuring scalability, reliability, and maintainability.
  • Deploy and monitor machine learning models and systems, including CI/CD pipelines, automated testing, monitoring, and model versioning.
  • Leverage cloud platforms (AWS + Snowflake) and ML infrastructure (e.g., SageMaker, feature stores) for scalable deployment.
  • Collaborate with cross-functional teams (Product, Customer Experience, and other engineering teams) to deliver AI-driven features and insights.
  • Ensure all ML/AI solutions adhere to best practices in data privacy, security, and ethical standards.
  • Contribute to a culture of technical excellence, knowledge sharing, and continuous learning.

What You Need To Succeed

  • University degree in Computer Science, Machine Learning, Data Science, or a related field.
  • 5+ years’ experience building and deploying production-grade machine learning models.
  • Strong software engineering mindset — ability to write clean, reusable, and scalable code in Python.
  • Experience integrating ML/AI models into production software systems.
  • Solid understanding of MLOps practices, CI/CD pipelines, and automated testing frameworks.
  • Hands-on experience with ML frameworks (e.g., TensorFlow, PyTorch, Hugging Face).
  • Experience working with backend teams and deploying end-to-end products.

What’s a Plus?

  • Background in data science: experimentation, A/B testing, and measuring ROI/impact of ML projects (not just accuracy).
  • Experience with NLP or generative AI techniques.
  • Familiarity with cloud-based ML infrastructure (AWS, Snowflake, SageMaker, etc.).

Why This Role?

  • Join a recently created AI team focused on delivering LLM and ML-powered projects with real business impact.
  • Lean, well-supported environment focusing on real use cases and improving user experience.
  • Full ownership of end-to-end ML delivery: from prototype to production.
  • Exposure to high-impact use cases backed by executive sponsorship and high visibility within the organization.
