About the Job

Requirements

  • A relevant scientific degree and extensive experience developing (not merely performing) ELISA, lateral flow assay, or other immunoassay techniques; examples include a PhD focused on developing these techniques or prior work as a Research Assistant or Scientist at a contract research organization, hospital, or immunoassay development company. Basic experience performing immunoassays during a Life Sciences bachelor's or master's degree is insufficient.
  • Awareness of product development, good laboratory practice, and safe working in an industrial laboratory.
  • Comfort working with human samples such as blood.
  • Ability to take a research question and design timely experiments to answer it, independently when appropriate, while accounting for required assistance, services, materials, and equipment.
  • Ability to format and analyse raw assay response data, derive concentrations from calibration curves, and reach definitive conclusions that can be documented for the company's Design History.
  • Ability to perform statistical tests to determine whether observations are significant.
  • Awareness of how deliverables fit within the broader assay-team development plan and ability to keep managers updated on project progress and blockers.
  • Ability to integrate into a new team and collaborate effectively.

Responsibilities

  • Work within the assay development team under a project leader's guidance to discover formulations and procedures for lateral flow assays.
  • Optimise existing formulations and improve assay-reagent manufacturing efficiency by testing changes to procedures identified independently or in discussion with the project leader.
  • Guide Research Assistants' work when experiments require support.
  • Use immunoassay technical knowledge to propose hypotheses and solve technical problems.
  • Maintain an electronic laboratory notebook to company standards, recording experimental data and observations.
  • Communicate work progress, findings, observations, and suggestions to the project leader and, occasionally, the wider company in collaborative meetings.
  • Help develop Research Assistants' technical skills while completing technical work and analysis together.

Desired Qualifications

  • Recent experience developing immunoassays in an industrial laboratory under ISO 13485 or ISO 9001 and good laboratory practice.

About the Company

Level Zero Health

Wearable biosensor for continuous hormone monitoring

Level Zero Health develops a biosensor platform for remote, continuous hormone monitoring using a minimally invasive arm patch. The patch uses DNA-based biosensors and microneedles to measure hormones like progesterone, estrogen, cortisol, and testosterone in interstitial fluid and sends real-time data to a connected system. It differentiates itself by delivering continuous wearable hormone data with validated accuracy and by targeting B2B clinical workflows in IVF, menopause care, and TRT, with plans to pursue regulatory approvals. Its goal is to replace infrequent blood or urine tests with continuous data streams to support personalized care and later expand into consumer and pharmaceutical markets.
