Our client platform delivers intelligent insights to property managers, letting agents, and landlords — helping them optimise building occupancy, understand resident profiles, and automate tedious admin tasks As we accelerate our machine learning and AI capabilities, we’re hiring a Python ML Engineer with hands-on LLM training experience to help us push the limits of what’s possible.

The Role

As our ML Engineer, you’ll work directly with the founding team and product leads to build, fine-tune, and deploy intelligent models that work on complex, real-world datasets.

This is a hands-on, high-impact role perfect for someone who thrives in a startup environment and wants to shape the future of real estate technology.

What You’ll Do

• Develop, train, and evaluate machine learning models using Python, with a focus on LLMs and structured/unstructured datasets
• Work with large and complex datasets including resident data, occupancy logs, utility consumption, and admin records
• Collaborate with the Tech Lead and Product team to turn customer problems into scalable ML features
• Explore and prototype model fine-tuning using OpenAI, Gemini, or similar APIs
• Monitor model performance and iterate quickly in a fast-paced production environment
• Contribute to the architecture and pipeline design for model training and inference
• Maintain clean, version-controlled, and well-documented code
• Optional: travel to the US for product workshops and strategy sprints
  
  

Must-Have Experience

• 5-7 years of experience in applied machine learning with Python
• Proven track record in training LLMs or working with LLM pipelines
• Strong experience working with complex, real-world datasets
• Previous experience in a startup or scale-up environment
• Solid understanding of ML frameworks (e.g. PyTorch, TensorFlow, scikit-learn)
• Comfortable with experimentation, testing, and deploying ML models in production
• Excellent communication skills and fluent English
  
  

Nice to Have

• Experience with OpenAI, Gemini, or other LLM APIs (prompting or fine-tuning)
• Domain knowledge or previous experience in real estate, proptech, or smart buildings
• Familiarity with ML ops practices and tools (e.g., MLFlow, Airflow, DVC)
• Ability to handle geospatial data, time series, or IoT data streams
• Interest in NLP, recommendation systems, or clustering algorithms
  
  

Join Us: This is a unique opportunity to join a dynamic team fully integrated with our startup partner and work on cutting-edge projects in a supportive and growth-oriented environment. We'd love to hear from you if you're a mid-level full-stack developer ready to take on a new challenge!
