Job description

Join a pioneering Quantum AI company that’s redefining how artificial intelligence is built and deployed!


Location: Madrid or Barcelona (Hybrid)

Contract: Fixed Term contract ending 30th June 2026


Responsibilities

  • Develop end-to-end data and model pipelines: source, augment, and validate datasets; design and manage training, fine-tuning, and evaluation workflows; deliver production-ready models that meet customer needs.

  • Design rigorous evaluation frameworks to ensure model competence and alignment through statistical testing, reliability assessment, and continuous monitoring.

  • Optimize training and inference performance using distributed compute resources, reducing latency, and identifying algorithmic or systems-level efficiency improvements.

  • Enhance models post-training by applying supervised fine-tuning (SFT), preference optimization, and reinforcement learning techniques to improve reasoning, safety, and helpfulness.

  • Compress and specialize models using advanced optimization techniques to meet performance and deployment constraints.

  • Collaborate across research and engineering teams on data curation, training experiments, model serving, and system observability.

  • Contribute to shared ML infrastructure, writing clean, well-tested, and maintainable Python code, documenting key decisions, and upholding high engineering standards.

  • Experience with data processing tools (NumPy, Pandas) and software best practices (Git, unit testing, CI/CD).

  • Solid understanding of language model training, architecture, and evaluation concepts.

  • Hands-on experience with large-scale datasets, including collection, cleaning, annotation, and quality assurance.

  • Practical experience using GPUs, containerized workflows (Docker), and distributed or cloud-based job orchestration.

  • Ability to interpret research papers, prototype rapidly, and turn ideas into reproducible, production-ready code.

  • Excellent communication skills and a collaborative, problem-solving mindset.
