Assay Lead
Montreal (in-person)Full-timePosted 1mo ago
About the role
Assay Lead to own the science behind the Hormometer®, leading the assay group on-site in Montreal, responsible for developing new biomarker assays from bench to commercial product and guiding validation, reagent formulation, and production support.
Responsibilities
- Lead the development of new lateral flow immunoassays for additional hormones, from concept through to commercial release.
- Own the performance specs (limit of detection, sensitivity, precision, stability) and design and run the analytical validation studies that demonstrate them.
- Own reagent formulation and stability, including shelf life.
- Troubleshoot assay challenges that surface during transfer, scale-up, and production, alongside our manufacturing team.
- Prioritize the experiment queue across the group: decide what gets run, what gets killed, and in what order.
- Hire and grow the assay team as we scale.
- Communicate research progress to a non-technical team.
- Keep clear, usable documentation of development and validation work.
Qualifications
- You have shipped a lateral flow assay to market. You carried it from bench through to a commercially released product, not just through late-stage development.
- You have roughly 5–8 years of assay development experience. We care far more about what you have shipped than about the number.
- You are still hands-on at the bench. You lead by doing, not by delegating.
- You have solved detection at very low concentrations in a crude, complex biological matrix. Saliva experience is a strong plus.
- You have dealt with reagent stability and shelf life, and with lot-to-lot variability that showed up in manufacturing rather than in development.
- You have worked in IVD, at-home testing, or point-of-care diagnostics.
- You can prioritize a research queue against a hard commercial deadline, and kill a dead end early.
- You explain technical uncertainty clearly to non-scientists.
- Advantage: You developed multiple different assays at a CRO, or shipped assays at more than one startup.
- Advantage: You have worked under ISO 13485 or with FDA requirements.
- Advantage: You have hormone-specific assay experience.
