Our partner is looking for a Technical Lead, Machine Learning based in United Kingdom.
This is a unique opportunity for an experienced Machine Learning leader to help build production-grade AI systems from the ground up. In this role, you will transform advanced AI research into scalable, reliable solutions powering next-generation applications. You will own critical areas including model fine-tuning, inference optimization, ML infrastructure, evaluation frameworks, and deployment processes. Working within a small, highly skilled engineering team, you will have significant technical ownership and influence architecture, engineering practices, and product direction. This position is ideal for someone who enjoys solving complex AI infrastructure challenges, mentoring engineers, and building innovative systems in a fast-moving environment.
Accountabilities
- Design, build, and scale production machine learning systems supporting advanced AI-powered applications.
- Own the infrastructure and execution layer required to train, deploy, monitor, and optimize large language models in production environments.
- Develop and maintain training pipelines, evaluation frameworks, and data workflows to continuously improve model performance.
- Fine-tune foundation models using modern techniques such as LoRA, QLoRA, supervised fine-tuning (SFT), and direct preference optimization (DPO).
- Optimize model inference performance, latency, reliability, and GPU resource utilization.
- Build high-quality datasets and establish robust evaluation processes to measure and improve AI system capabilities.
- Manage deployment workflows, monitoring, observability, and reliability of machine learning services.
- Define engineering standards, contribute to technical strategy, and promote best practices across the ML engineering function.
- Mentor and support a high-performing machine learning team while fostering a culture of ownership and technical excellence.
- Collaborate closely with backend engineers, product teams, and other stakeholders to translate AI capabilities into impactful user experiences.
