About EndlessDx Laboratory (www.endlessdx.com)

At EndlessDx, we're building a vertically integrated diagnostics company that controls the full stack—from the collection device in a patient's hand to the validated result in their clinician's portal. We're CLIA/CAP-accredited and focused on making precision diagnostics radically more accessible through innovations in self-collection, sample stability, and laboratory science.

We're a small, fast-moving team that values speed, frugality, hard work, deep technical growth, clever experimental design, and smart, practical science. If you want your research to ship in real products that reach real patients—not sit in a journal—this is the place.

What You’ll Do

• Design, develop, and characterize materials and formulations for blood stabilization, analyte preservation, and extraction from self-collected specimen matrices.

• Lead bench‑scale R&D on novel collection device chemistries—evaluating stabilizer systems, desiccants, separation media, and surface treatments for compatibility with downstream clinical assays.

• Develop and execute DOE‑driven studies on analyte recovery, matrix effects, and long‑term stability across temperature and humidity conditions.

• Collaborate closely with our analytical chemistry and laboratory teams to ensure material innovations translate to validated, CLIA‑grade workflows.

• Author technical reports, SOPs, and IP documentation; contribute to regulatory submissions and design history files as needed.

• Stay current on emerging biomaterials, microfluidics, and dried specimen technologies; bring new ideas to the roadmap.

What You Bring

• MS or PhD in Materials Science, Biomedical Engineering, Chemical Engineering, Biochemistry, or a closely related field (BS with exceptional experience considered).

• 3+ years of relevant industry experience working at the intersection of materials science and biological systems—ideally in diagnostics, medical devices, or bioanalytical sample preparation.

• Strong hands‑on research skills: you're comfortable designing experiments, running characterization (e.g., DSC, FTIR, SEM, contact angle, rheology), and interpreting results in a biological context.

• Demonstrated understanding of blood biochemistry—protein adsorption, hemolysis, coagulation cascades, analyte degradation pathways—and how material properties influence them.

• A builder's mindset: you care about scientific rigor, but you're equally driven to see your work manufactured, shipped, and used.

Bonus Points For

• Direct experience with dried blood spot (DBS) or volumetric microsampling device development.

• Familiarity with polymer chemistry, hydrogel systems, or functionalized membrane design for biofluid applications.

• Exposure to FDA 510(k), ISO 13485, or design control frameworks for IVD or medical devices.

• Experience with contract manufacturing scale‑up from bench prototypes to production.

Why This Role Matters

Our collection and stabilization technology is what makes self‑collected, mail‑in diagnostics possible at scale. The materials you develop will directly determine which analytes we can offer, how stable they remain in transit, and ultimately how many patients get access to precision health insights they couldn't get before. You'll work alongside a small, sharp team—including our lab director and CEO—with a clear line of sight from your bench work to products in the field. You will grow fast here.

We offer meaningful equity because we want our early team members to share in the upside of building something important and enduring.
