We currently have approximately 50 models in production that are all trained and monitored regularly.
Do you want to be part of the next step in our growth journey?
We are in search of a Machine Learning Engineer with the ability to work in an energetic and interactive environment. You must be a self-starter with a passion for crafting innovative ML solutions and as part of our team work closely with our data scientists and data engineers. You will regularly learn and implement new technologies, and play an active role in developing, proving out, and (re)assessment of existing machine learning architectures. You will also be in close collaboration with our DevOps and system engineers in order to consciously improve our infrastructure and our CI/CD environment and process.
Main tasks
- Design, build and train robust machine learning models using appropriate algorithms and techniques. This includes experimenting with different architectures and hyperparameters to optimize performance for specific business needs.
- Modify/tune existing models, data pipelines and related functionality according to market fluctuations or stakeholder needs.
- Clean, transform and prepare large and complex datasets for model training. You'll also identify and engineer relevant features to improve model accuracy and efficiency.
- Rigorously evaluate model performance using various metrics, conduct thorough validation and ensure models are reliable and generalized well before deploying them into production.
- Design, implement and maintain scalable and reliable infrastructure for model training, testing and deployment, including using our on-prem platform, CI/CD pipelines and containerization technologies.
- Deploy trained models into prediction services, monitor performance and proactively troubleshoot issues to ensure model accuracy and uptime.
- Work closely with data scientists, data engineers, software engineers and business stakeholders to define requirements, design end-to-end solutions and drive impact through data-driven applications.
- Continuously optimize models for speed, memory consumption, and overall efficiency, ensuring cost-effective and scalable operations.
- Keep up with state-of-the-art research, tools and techniques in the field of machine learning and share your learnings with the team.
Learning curve
In this role you will be using the best selection of tools and processes in the ML domain. The role enables you to learn even more about creating, developing and implementing standards for ML applications, and get deep knowledge about ML concepts and frameworks. You will also have the possibility to learn more about (and get hands-on experience of) adjacent fields like Data Engineering and Data and ML Platform Architecture.
Requirements
