About the Job

Requirements

  • A Ph.D. in electrochemistry, analytical chemistry, biochemistry, chemical or materials engineering, or a related discipline, focused on aptamer biosensors.
  • Hands-on experience in biosensor design, electrochemical techniques, and surface chemistry optimization.
  • Proficiency operating electrochemical instrumentation and analyzing experimental data.
  • Expertise with biorecognition elements, particularly aptamers, for biosensor applications.
  • Knowledge of small-molecule detection in biological or environmental samples.
  • Practical experience handling and analyzing biofluids.
  • Strong problem-solving and troubleshooting skills.
  • Ability to communicate and work effectively with multidisciplinary teams.

Responsibilities

  • Design, prototype, and optimize electrochemical biosensor systems focused on small-molecule analytes and aptamer-based recognition.
  • Apply surface chemistry and electrode modification strategies to improve sensitivity, selectivity, stability, and performance in complex biological samples.
  • Translate bio-element–target interactions into measurable and reproducible sensor outputs through assay design.
  • Use electrochemical methods, including voltammetry, impedimetry, and chronoamperometry, to characterize and evaluate biosensor function.
  • Apply data-driven approaches, including Python-based analysis and Design of Experiments, to streamline workflows.
  • Troubleshoot technical and conceptual challenges and propose solutions to improve performance.
  • Develop and maintain Standard Operating Procedures and ensure experimental reproducibility and compliance with quality standards.
  • Collaborate with chemists, biologists, engineers, and data scientists to advance biosensor prototypes from concept to application.
  • Present results through written reports, oral presentations, and scientific publications.
  • Attend research and development training and seminars to stay current with hormone-sensing technologies.

Desired Qualifications

  • Postdoctoral experience.
  • Experience with Surface Plasmon Resonance, molecular docking, or structural modeling.
  • Familiarity with automation, Python scripting, and statistical design approaches such as Design of Experiments.
  • A track record of peer-reviewed publications, patents, or industry-led biosensor projects.

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.
