Machine Learning Engineer - ML Systems & Frameworks

Machine Learning Engineer

AI Systems & Frameworks

Level : Junior (1-3 years)

Location(s) : Barcelona, Spain

Job Type : Full-time

About the role

We are seeking a Junior Machine Learning Engineer to join our high-performance team collaborating with leading AI chip companies. Our work focuses on developing software that enables users to run Vision and Generative AI inference workloads efficiently on custom accelerators.

This is a hands-on engineering role where you will contribute to the development of frameworks, APIs, and runtime integrations that power AI models on next-generation hardware. You will work alongside senior engineers and coordinate with compiler / runtime and hardware architecture teams.

This is not a traditional applied ML position. It suits someone who wants to build a strong foundation in AI / ML systems, performance optimization, and software engineering, while contributing to production-grade AI enablement.

What You’ll Do

• Assist in implementing scalable software architecture and design patterns.
• Help develop Python / C++ frameworks that integrate ML models with custom runtimes.
• Contribute to building high-performance APIs, bindings, and libraries for Vision and Generative AI inference.
• Support Model Zoo maintenance, model loaders, and optimization workflows for easier deployment.
• Profile, debug, and optimize performance-critical sections in framework and runtime layers.
• Contribute to real-time pipelines using GStreamer, OpenCV, and related frameworks.
• Collaborate with compiler / runtime teams on graph-level and operator optimizations.
• Apply best practices in design, testing, CI / CD, and code reviews.
• Participate in end-to-end software delivery, including defining scope and meeting project timelines.
