Founding AI / ML Engineer - Known

About the role You’ll develop and deploy the ML systems that make Known work - from compatibility scoring and recommendations to natural language/voice interaction. You’ll work closely with platform engineers to shape the data foundation and with product engineers to deliver delightful user experiences.Responsibilities • Design and implement profile matching algorithms (recommendations, search, personalization). • Build ML-specific pipelines for model training, evaluation, and inference at scale. • Research, experiment, and productionize agentic workflows to power voice agent and other similar functionalities • Deploy models into production and ensure monitoring, retraining, and evaluation loops. • Partner with the product team to run offline & online experiments to improve outcomes.Requirements • 4+ years in applied ML engineering. • Expertise in Python with ML frameworks (PyTorch, TensorFlow). • Experience with recommendation/search/matching systems and LLM/agentic workflows. • Expertise in reinforcement learning is a big plus. • Familiar with model deployment, A/B testing, and monitoring in real-world systems.Example Projects • Develop an embeddings-based retrieval + re-ranking system for user compatibility. • Deploy a lightweight LLM agent for intake calls/voice matching. • Build an evaluation harness for offline model testing and online experimentation.
