Product Manager, Mail-In Blood Testing

**About SiPhox Health** SiPhox Health is building the leading home testing platform for biomarkers across inflammation, hormones, and metabolic and cardiovascular health. Six in ten Americans live with a chronic disease, and our mission is to make early detection possible from home. We operate two business lines, both scaling quickly: 1. **Mail-in blood testing**: Growing more than 50% quarter over quarter, and the most comprehensive and highly rated at-home blood testing available today.

2. **At-home blood testing device**: Planned launch in 2027. Our chip-based module combines biochemistry with integrated photonics, electronics, and microfluidics, protected by more than 50 patents. SiPhox is an MIT startup backed by Tier I investors including Y Combinator, Khosla Ventures, and Intel Capital. **The Role** This is not a product-maintenance role. It is a role defined by urgency, ownership, and consequence.\ \ We build and deliver a physical product to customers' homes.

It is filled with their blood, processed by laboratories under regulatory scrutiny, and returned as a result on which they will base real health decisions.\ \ We are looking for someone who takes ownership of the full product lifecycle, execution and quality, who moves decisively under pressure, and who is willing to implement a practical solution now rather than wait for a perfect one later. Candidates who require a fully mature organization, established handoffs, and a documented procedure for every situation will not find that here.

The ideal candidate is prepared to build those systems while the operation runs at full speed.Areas of Ownership **Product ownership, mail-in blood testing** The product is both the physical kit and the digital results experience.
