About Bask Health
Bask Health is a software platform that enables entrepreneurs, doctors, and healthcare businesses to launch, manage, and grow direct-to-consumer telehealth businesses.
Our platform brings together patient experiences, clinical workflows, pharmacy operations, and commerce tools in one place.
We're an entrepreneurial, product-focused engineering team that values ownership, technical excellence, and building software that solves real problems. Engineers work closely with product teams and company leadership, take features from idea to production, and have a direct role in shaping the platform.
Engineering at Bask is AI-first and builder-led. We use tools like Cursor and Claude Code throughout development while maintaining high standards for reliability, testing, and software quality.
About the Role
We're looking for an ML Platform Engineer, Evaluation Systems to build and maintain the infrastructure that allows Bask Health to evaluate machine learning models and AI-powered applications reliably, consistently, and at scale.
Bask Health supports direct-to-consumer telehealth businesses through a platform that connects patient experiences, merchant operations, clinical workflows, pharmacy coordination, and commerce capabilities. As machine learning and AI become more integrated into these systems, we need dependable infrastructure for measuring model quality, comparing changes, and understanding how AI systems perform before and after deployment.
You'll help develop the platform services, data pipelines, execution environments, and monitoring capabilities that support machine learning evaluation across engineering teams.
This is a hands-on engineering role focused on the operational infrastructure behind evaluation systems. You'll work with cloud services, distributed processing, model integrations, databases, and automated workflows to support repeatable experiments and large-scale evaluation jobs.
Your work may include building evaluation job orchestration, managing benchmark datasets, developing experiment tracking systems, supporting model comparisons, and creating infrastructure that stores and analyzes evaluation results.
You'll collaborate with machine learning engineers, applied scientists, AI evaluation engineers, and backend engineers to understand their technical requirements and build reusable systems that support different model types and evaluation methodologies.
You'll also help improve the reliability and reproducibility of evaluation workflows. This includes ensuring experiments can be repeated, datasets and configurations are versioned, failures are observable, and results can be compared accurately over time.
Because Bask operates in healthcare-related environments, evaluation infrastructure must support appropriate privacy controls, secure data access, and responsible handling of sensitive information. You'll help ensure evaluation datasets and model outputs are managed according to approved security and operational requirements.
This position emphasizes strong infrastructure engineering, practical machine learning knowledge, and ownership of production platform services. You'll contribute to architecture, build scalable systems, improve operational performance, and help engineering teams evaluate AI capabilities more effectively.
We're looking for an engineer who enjoys building infrastructure for machine learning teams, understands the challenges of reproducible experimentation, and wants to make AI evaluation more dependable and efficient across the organization.
