Python ML Engineer

Employment Type: Full-Time Location Type: Remote (U.S. Based Applicants Only) Salary: Not Specified

Position Overview

Solace is a healthcare advocacy marketplace that connects patients and families to experts who help them understand and take charge of their personal health. As a Python ML Engineer at Solace, you will own the deployment and operationalization of machine learning models that power intelligent features across our platform. You will work closely with data scientists and product teams to take algorithms from prototype to production, building scalable, reliable systems in AWS that directly improve healthcare access and outcomes for our patients. You are a builder at heart—someone who can navigate between code, infrastructure, and real-world impact. You understand the ML lifecycle end-to-end and thrive on making advanced analytics deployable, observable, and maintainable.

About Solace

Healthcare in the U.S. is fundamentally broken. The system is so complex that 88% of U.S. adults do not have the health literacy necessary to navigate it without help. Solace cuts through the red tape by pairing patients with expert advocates and giving them tools to make better decisions—and get better outcomes.

We're a Series B startup, founded in 2022 and backed by Inspired Capital, Craft Ventures, Menlo Ventures, Torch Capital, and Signalfire. Our fully remote U.S. team is lean, mission-driven, and growing fast. Solace isn’t a place to coast. We’re here to fix healthcare—and that takes urgency, precision, and heart. If you're ready to stretch your skills, ship impactful ML infrastructure, and collaborate with a high-performance team, you're in the right place.
