Overview

Quantum Computing & AI software company based in Barcelona seeks a Deep Learning Engineer. This is a fixed-term contract until June 2026.

Responsibilities

-

- Lead the end-to-end design, training, optimization, and evaluation of deep learning models (LLMs and computer vision), from data preparation through large-scale distributed training and deployment.

- Research, apply, and advance state-of-the-art model compression techniques—including pruning, distillation, quantization, and architectural optimisation—to balance accuracy, latency, cost, and hardware constraints.

- Build and maintain reproducible, automated pipelines for large-model training and compression, incorporating ablation studies, benchmarking, and systematic evaluation.

- Develop and curate datasets and fine-tuning strategies (e.g., SFT, preference optimisation, prompt engineering) tailored to domain-specific and real-world use cases.

- Integrate compressed models into production systems,



collaborating closely with cross-functional teams while maintaining high engineering standards, documentation, and code quality.

Qualifications

-

- Master’s or Ph.D. in Computer Science, Machine Learning, Electrical Engineering, Physics, or a closely related technical field.

- 3+ years of hands‑on experience training deep learning models from scratch, including architecture design, data pipelines, training loops, and distributed training.

- Strong expertise in model compression methods (pruning, distillation, low-rank factorisation, quantization) and performance analysis through ablations and error diagnostics.

- Deep understanding of modern model architectures (LLMs and/or computer vision), training dynamics, optimisation techniques, and the full model lifecycle. xqbhyrx

- Proficiency with Python, PyTorch, and modern ML tooling, along with experience building scalable, reproducible training pipelines and optimizing models for real-world deployment constraints.
