Staff Applied Machine Learning Scientist

Staff Applied Machine Learning Scientist

You are a seasoned applied machine learning scientist (6+ years solving real-world ML problems) with deeply held perspectives on modeling techniques, data workflows, and the infrastructure that unlocks world-class ML systems. Your opinions are rooted in experience—trial, error, and relentless iteration—and they make you surgically effective at building models that actually move the needle.

While you are deeply knowledgeable about LLMs and agents (and getting tired of explaining AI to your friends) you aren't here to just “talk to the LLM.” You build and deploy models that matter—real-time, low-latency systems powered by massive feature stores that serve predictions in the critical path for the world’s biggest enterprises. You work where modeling meets engineering, and you're driven by one thing: making machine learning deliver actual value in production. You’ve wrangled your share of Spark jobs, tuned XGBoost until your eyeballs hurt, and carried a real-time model from notebook to uptime SLA.

You are a technical leader. You guide ML engineers and cross-functional peers by sharing your insights, offering principled critiques, and demonstrating the courage to make the hard calls. You celebrate your team’s wins as much as your own. You mentor through code reviews and modeling walkthroughs. You thrive in the flow state—those moments where a thorny modeling challenge untangles in your mind, and you can just build.

You don’t believe in ivory towers. When data quality is a mess, you dive in. When your model doesn’t work in production, you debug the pipeline, the feature store, and the service endpoint until it does. You're insatiably curious. New modeling techniques? Let’s test them. Advances in streaming architectures? You're already thinking about integration points. You read papers, try repos, and turn research into production-ready code. You’ve deployed ML to AWS, GCP, or both, and know what it takes to make a model fast, scalable, and maintainable.

We’re not looking for someone to prompt their way to mediocre answers. We’re looking for someone who can model the hard stuff—fast decisions, messy data, and enterprise-scale expectations.

Think you’ve got what we need? Let’s find out.
