Job Description

We are looking for a Senior Machine Learning Engineer – Computer Vision to join our team and help us tackle complex visual understanding tasks using deep learning. This role is ideal for someone with a strong background in image analysis, object detection, segmentation, and classification, and who thrives in a collaborative, agile environment.

The ideal candidate combines solid software engineering skills with deep expertise in modern computer vision techniques. Experience with PyTorch is essential, as is familiarity with advanced architectures such as Transformers, Foundation Models, and Vision-Language Models (VLMs). Hands-on experience deploying optimized models in on-premise high-performance environments is highly valued. Our infrastructure processes data at petabyte scale, so attention to performance and scalability is critical.

We are seeking someone with great attention to detail and rigor, who understands the importance of clean code, reproducible ML workflows, and thoughtful experimentation. Curiosity and a desire to continuously learn and grow are essential, as is the ability to communicate clearly and effectively within a collaborative team environment.

Responsibilities: Machine Learning & Computer Vision

• Develop and deploy deep learning models for object detection, segmentation, and image classification.
• Leverage state-of-the-art architectures including Vision Transformers, Foundation Models, and VLMs.
• Design and execute experiments, ensuring reproducibility and scientific rigor.
• Analyze model performance and iterate to achieve production-grade results.
• Optimize inference pipelines for efficiency and scalability.

Software Engineering & MLOps

• Write clean, modular, and well-documented Python code.
• Contribute to code reviews, pull requests, and team knowledge sharing.
• Build and maintain training and deployment pipelines.
• Integrate models into production systems using best practices.
• Follow agile development (SCRUM) and CI/CD workflows.

Data & Infrastructure

• Work with large-scale image datasets, including geospatial data.
• Use GIS tools and libraries (GeoPandas, rasterio, etc.) when needed.
• Deploy and serve models on on-premise infrastructure using NVIDIA Triton for high-performance inference.
• Ensure compliance, reproducibility, and scalability in data and model workflows.

Qualifications & Required Skills

• 4+ years of experience in deep learning applied to computer vision.
• Proficiency in Python and PyTorch.
• Solid understanding of CNNs, object detection, segmentation, classification pipelines.
• Experience working with Vision Transformers, Foundation Models, or multimodal architectures.
• Familiarity with MLOps tools.
• Experience in agile environments with team-based development (SCRUM, pull requests, code reviews).
• Strong attention to detail and a results-driven mindset.
• Professional proficiency in English.
• Ability to work in a multicultural team.

Preferred Skills

• Experience with GIS and geospatial data processing.
• Experience deploying models in on-premise and AWS.
• Experience with large-scale datasets and model optimization techniques.
• Experience with databases, preferably PostgreSQL, at a developer level.

What We Offer:

• Permanent full-time position.
• Salary based on experience.
• 100% remote, hybrid, or on-site work (Alcorcón, Madrid), candidate's choice.
• Flexible compensation: health insurance, meals, training, childcare.
• Challenging and rewarding environment within a multinational company in expansion.
• Access to vast data for impactful projects within a Machine Learning / Computer Vision team.

You will work with real problems from day one, with responsibility and freedom to execute your ideas.
