Job description

About Level Zero

Level Zero is pioneering next-generation biosensor technology for precise, real-time monitoring of critical endocrine biomarkers. Recognised as one of the top 20 startups across all categories worldwide at TechCrunch Disrupt 2024 - and backed by top-tier organisations like Redalpine, SOSV, and Entrepreneur First - we’re pushing the boundaries of biochemistry and nanotechnology to revolutionize personalised health.

Founded by two seasoned engineers, we bring extensive experience in R&D, technical innovation, and commercial strategy to transform the way people monitor their health. Our mission is bold: to revolutionise health management by delivering clinical-grade data directly to individuals, wherever they are.

We’re seeking driven innovators to join us in pushing the boundaries of biosensing and health tech, making personalised health monitoring a reality for everyone. To achieve this ambitious vision, we’re assembling the best team in the world - dedicated to turning cutting-edge science into life-changing, real-world solutions.

What You’ll Do

• Work within the assay development team under supervision of a project leader to help discover new formulations and procedures for LZH lateral flow assays
• Further optimise existing formulations and improve manufacturing efficiency of assay reagent manufacturing by testing the effect of certain changes to procedures as agreed with your project leader
• Use technical knowledge of immunoassays to make suggestions of hypotheses to test in the aforementioned areas and solve technical problems
• Maintain electronic laboratory notebook to the required company standard, diligently recording data and observations from experiments you perform
• Communicate all work (progress, findings, observations, suggestions) your project leader and on occasion to the wider company in collaborative meetings

What You Bring

The ideal candidate must have:

• Relevant Scientific degree and extensive experience performing ELISA, LFA or other immunoassay technique. e.g. these techniques were the focus of a masters degree (rather than a technique used only on occasion) or previous work at a CRO, hospital or immunoassay development company as a technician or RA
• Awareness of product development, good laboratory practice and safe working in an industrial laboratory
• Be comfortable working with human samples such as blood
• Ability to format and analyse raw assay response data (derive concentration from calibration curve) and suggest conclusions
• Ability to perform basic statistical tests to conclude if observations are significant or not
• Ability to integrate quickly into a new team and work well with others, as the role will be collaborative

Nice to have

• Recent experience working under ISO13485 or ISO9001 and GLP in an industrial laboratory, performing immunoassays or developing them

Who You Are

We value culture as much as we value technical expertise, creating an environment that’s equal parts collaboration, curiosity, and fun.
