We are looking for a Machine Learning Engineer to help scale the industrialization of our ML lifecycle. This is a Builder’s Role - you will be responsible for the high-scale architecture that allows our models to survive production. You’ll be a key contributor to our MLOps ecosystem, moving beyond experimentation to build high-throughput, distributed systems that serve as the backbone of our intelligence products.

Machine Learning Engineers help us extract value from our data. They are involved in all the processes from data collection, cleaning, and preprocessing, to training models and deploying them to production. This position will assess, analyze, and organize data, execute tests, and optimize the learning process to develop high-performance machine learning models.

• Develops software using the KnowBe4 Software Development Lifecycle and Agile Methodologies
• Designs, develops, and researches Machine Learning systems
• Transforms data science prototypes by applying appropriate Machine Learning algorithms and tools
• Performs statistical analysis and using results to improve models
• Inference Engineering: Drive the deployment and optimization of both standard predictive models and LLM architectures, balancing trade-offs between low latency, high throughput, and cost-efficiency
• Platform Hardening: Transition research prototypes into resilient, production-ready microservices that can handle massive traffic
• Lifecycle Orchestration: Execute automated pipelines for data and model versioning, validation, and retraining
• Observability: Implement advanced monitoring for model drift, data integrity, and system health to ensure production reliability

The Reality Check:

While the title says pure ML, the day-to-day is data heavy and is also focused on the AI and ML Platform Engineering around our services. Expect a roughly 90/10 split - the vast majority of your impact will come from hardening data pipelines, refining CI/CD for ML, and building world-class observability, with the remaining portion dedicated to model building, implementation and tuning.
