Founding Machine Learning Engineer

compensation and huge ownership over the ML platform from day one.

Responsibilities Define Adaptive's ML strategy: where ML should be applied across our products, what infrastructure we need, and how we should approach build vs. buy decisions. Design and build production ML systems end-to-end — data pipelines, model training, evaluation frameworks, and inference serving. Establish evaluation methodology. Define how we measure model quality, catch regressions, and make data-driven decisions about model changes. Own the strategy for getting the data you need, in the format you need it — what/how to label, how to build feedback loops, and how our models improve over time. Partner with product engineers to integrate ML into the product. You will write production code and work within our existing codebase. Build and lead the ML team as scope grows.

Qualifications 8+ years of experience building ML systems in production, ideally with experience standing up the ML function at an early stage startup or as the senior or lead ML person at a previous company. Strong software engineering fundamentals. You write production-quality code in modern languages (Python, Java, TypeScript) and work within large codebases. Experience with cloud ML infrastructure (AWS SageMaker, Bedrock, Modal, Baseten, or similar). Experience with common ML and data processing frameworks (PyTorch, Tensorflow, Spark) Comfortable working across the stack — infrastructure, backend services, and data systems. Track record of mentoring MLEs and other engineers with observable, clear improvements in those you've worked with. High autonomy. You'll have support and context from leadership, but you're expected to define the path forward and drive it.
