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:

• Mail-in blood testing : Growing more than 50% quarter over quarter, and the most comprehensive and highly rated at-home blood testing available today.
• 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
