About Tiny Health

Tiny Health is the first precision microbiome intelligence platform dedicated to helping every person start — and stay — healthy for life. Founded in 2020 by microbiome scientists, practitioners, and engineers, we’re redefining personalized health starting with clinical-grade gut and vaginal microbiome testing. We’ve built an AI-powered engine to train our platform with the latest scientific research on top of our proprietary bioinformatics pipeline leveraging shotgun metagenomics.

Trusted by +150,000 customers and +5,000 practitioners, Tiny Health’s mission is to make the microbiome measurable, accessible, and actionable at every life stage, from birth through healthy aging. Our vision is to build a world where chronic conditions are prevented and course-corrected through evidence-based microbiome interventions.

If you’re passionate about cutting-edge science, health innovation, and helping people live better lives through root cause solutions, join us in shaping the future of precision medicine. Learn more at tinyhealth.com and poweredbytiny.com

The Role

We are looking for an AI Engineer to join our Product & Engineering team. This role will focus on building and scaling production-grade AI systems that power Tiny Health’s consumer and clinician-facing products. You’ll work closely with our co-founder, product/design lead, and a small, high-performing engineering team to design and implement AI-driven features, pipelines, and infrastructure that drive meaningful health insights.

We are seeking someone who has hands-on experience deploying AI applications in production, beyond prototypes or personal projects. You should be comfortable owning end-to-end delivery — from model integration to infrastructure — and capable of operating independently in a fast-moving environment.

If you’re at the lead level, you’ll also help shape Tiny Health’s AI roadmap, set technical direction, and mentor engineers as we expand our AI capabilities.

Key Responsibilities

• Design, build, and maintain production-grade AI systems and APIs that power our products.
• Integrate and fine-tune models (LLMs, embeddings, or other ML architectures) for customer-facing and internal use cases.
• Own the full lifecycle of AI features — from research and prototyping to productionization, deployment, and monitoring.
• Collaborate closely with engineering, product, and science teams to scope and ship impactful AI-driven features.
• Design data pipelines, retrieval systems, and scalable infrastructure for inference and model serving.
• Ensure performance, observability, and reliability of AI components in production.
• (Depending on experience) Lead AI initiatives, guide architecture and system design decisions, and mentor other engineers.

Qualifications

Must-Haves:

• Proven experience building and deploying AI or ML systems in production at scale (not just prototypes or demos).
• Deep understanding of model integration workflows — from inference pipelines to prompt engineering, fine-tuning, or RAG setups.
• Strong backend engineering background (Python or Node.js preferred).
