Senior / Mid LLM Engineer – Applied AI & Model Optimization (San Sebastián, Spain) Hybrid About the opportunity We are partnering with a fast-scaling deep-tech company operating at the intersection of advanced AI, large language models, and next-generation computational techniques. The team focuses on solving real-world, high-impact problems by building and optimizing AI systems used by general enterprises across industries such as finance, energy, and industrial operations. This is not a pure research role — it’s applied AI at scale, where your work directly translates into production-ready solutions. Role mission As an LLM Engineer, you will play a key role in designing, improving, and deploying large language models, with a strong focus on efficiency, scalability, and real-world applicability. You’ll work on challenging problems such as model compression, performance optimization, and integration into complex systems, collaborating with highly technical teams in a fast-paced environment. What you’ll be doing
- Design and improve LLM architectures and optimization techniques for real-world use cases.
- Fine-tune and evaluate transformer-based models to enhance performance and efficiency.
- Work on model compression and acceleration strategies.
- Run benchmarks, analyze model behavior, and identify performance bottlenecks.
- Contribute to the deployment of AI models in production environments.
- Collaborate with cross-functional teams (engineering, data, product).
- Mentor junior engineers and contribute to technical decision-making.
- Stay up to date with the latest advancements in LLMs and applied AI. #J-18808-Ljbffr Postúlate en Kit Empleo: kitempleo.es/empleo/6u3t7b
