I korthet

Ericsson is seeking a Senior Data Scientist II to lead the design and implementation of AI/ML models, including Agentic AI systems and LLM-powered applications. The role requires 8-14 years of experience, strong Python and SQL skills, and production deployment experience.

Ansvarsområden

  • Lead the design and implementation of machine learning and statistical models to solve complex business problems.
  • Architect and build Agentic AI systems, including multi-agent pipelines and autonomous reasoning loops.
  • Design and deploy LLM-powered applications, including RAG pipelines and fine-tuned domain models.
  • Collaborate with cross-functional teams to identify AI-driven solution opportunities.
  • Perform data exploration, feature engineering, and dataset curation.
  • Evaluate model performance using rigorous metrics, ensuring interpretability, fairness, and robustness.
  • Contribute to reusable AI frameworks, internal tooling, and shared libraries.
  • Stay at the forefront of AI/ML research, tracking arXiv, open-source releases, and industry developments.

Krav

  • 8–14 years of applied Data Science and Machine Learning experience, with demonstrated progression in scope and complexity of owned systems.
  • Deep expertise in classical ML - regression, classification, clustering, ensemble methods, time-series modeling, and anomaly detection.
  • Hands-on experience building LLM-based systems: RAG architectures, prompt engineering, context window management, vector databases, and LLM orchestration frameworks.
  • Practical experience designing Agentic AI workflows - including tool-calling agents and memory architectures.
  • Proficiency in model fine-tuning techniques: LoRA, QLoRA, PEFT, instruction tuning, and RLHF/DPO alignment approaches.
  • Strong programming skills in Python, with proficiency in SQL and familiarity with distributed data processing.
  • Solid software engineering discipline - clean, well-tested, reproducible code with CI/CD awareness.
  • Experience deploying and scaling AI models in production with robust monitoring, observability, and performance management.
  • Proven track record of end-to-end ownership of AI/ML projects - from problem framing through production deployment and iteration.

Önskade kvalifikationer

  • Master's or PhD in Computer Science, Statistics, Mathematics, or a related field.
  • Experience with deep learning frameworks (PyTorch, TensorFlow) and training or fine-tuning large models.
  • Familiarity with model safety, guardrails, and responsible AI practices, including output filtering, hallucination mitigation, and bias evaluation.
  • Experience with function calling / tool use patterns in LLMs and building structured, reliable agent behaviors.
  • Domain exposure in telecom, network operations, or AIOps is highly desirable.
  • Contributions to open-source AI projects or published research is a plus.

Förmåner

  • Outstanding opportunity to use your skills and imagination to push the boundaries of what’s possible.
  • Work on solutions never seen before to some of the world’s toughest problems.
  • Be challenged, but not alone – join a team of diverse innovators.
  • Opportunity to craft what comes next.
