## About the Role

* 2+ years building ML systems in production, ideally for consumer-facing products.
 * Strong ML fundamentals across supervised learning, sequence/time-series modeling, and modern deep learning.
 * Hands-on experience with large-scale model training and evaluation (PyTorch/TensorFlow/JAX), and strong Python engineering practices.
 * Experience with personalization systems (ranking/recommendations, segmentation, lifecycle modeling, propensity/behavior modeling, causal/experiment-aware thinking).
 * Fluency with data tooling (SQL, distributed compute such as Spark/Ray, and cloud storage/compute).
 * Strong product sense: you can translate ambiguous goals into measurable outcomes and iterate quickly with stakeholders.

Bonus Points

 * Experience applying LLMs/foundation models to product features (tool use, retrieval, structured outputs, guardrails, evals).
 * Experience with multimodal data (sensor signals + context) and/or health/biometrics data.
 * Experience with privacy-preserving approaches (on-device/federated learning, differential privacy, data minimization).
 * Experience designing experimentation frameworks or causal inference approaches for personalization.

## Description

We're looking for a Machine Learning Engineer to build and ship consumer-facing AI systems that power personalization, coaching, and next-generation "sleep intelligence." You'll work across data, modeling, product, and engineering to translate research into reliable, measurable improvements for members.

This role is ideal for someone who loves end-to-end ownership: from problem framing prototyping offline evaluation online experimentation production deployment iteration.

How you'll contribute

 * Build and deploy ML models that improve sleep experiences through personalization, prediction, and behavior understanding (e.g., readiness forecasting, event detection, individualized recommendations).
 * Apply and adapt foundation-model capabilities to real product workflows (LLM + tools/RAG, multimodal modeling, policy learning), including MCP-style integrations where helpful.
 * Develop user behavior models that connect longitudinal signals (sleep, environment, routines) to actionable interventions - grounded in robust experimentation and measurement.
 * Design evaluation strategies (offline metrics, slice-based analysis, calibration, reliability, fairness) and partner with Product to run high-quality online experiments.
 * Productionize models: scalable training/inference pipelines, model monitoring, drift detection, alerting, and continuous improvement loops.
 * Collaborate with cross-functional partners (Product, Mobile, Backend, Clinical) to scope requirements and ship high-impact features., From your first day, you'll take on substantial responsibilities that have a direct impact on our core business and product success. We are a small team that empowers you to own your projects and see the tangible effects of your efforts, enhancing both your professional growth and our company's trajectory. Your path will be challenging but rewarding, perfect for those who thrive in fast-paced environments aiming for high standards.

Collaboration with exceptional talent

Work alongside other bright minds like you: at Eight Sleep exceptional intelligence and a passion for breakthroughs are the norms. Our team members are not only experts in their fields but also avid innovators who thrive in our dynamic, fast-paced environment.

Equitable compensation and continuous equity investment

We extend equity participation to every full-time team member, recognizing and rewarding your direct contributions to our success. This includes periodic equity refreshments based on performance, ensuring that as Eight Sleep grows and succeeds, so do you - perfectly aligning your achievements with the broader triumphs of the company. Pay grows rapidly as you accumulate experience with Eight Sleep and translate it into concrete impact.

Your own Pod - and other great benefits

Every Eight Sleep employee receives the very product that defines our mission: a Pod of their own. If you join us you'll get your own Pod, along with other benefits. Learn more at eightsleep.com/careers
