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.

About this role

We’re looking for a Research Associate (Immunoassay) to help build and scale assay development at Level Zero Health, accelerating our mission to deliver clinical-grade, real-time biomarker monitoring through next‑generation biosensing. Working within the assay development team and alongside a project lead, you’ll help develop and optimise lateral flow assay formulations and manufacturing procedures, design and run experiments to test hypotheses and solve technical problems, and turn raw assay data into clear conclusions that drive iteration.  

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.

We’re a fast-paced, mission-driven young team on a quest to make a lasting impact, fueled by uncompromising integrity, unwavering support for one another, and the thrill of exploring uncharted territories. Our passion for excellence drives everything we do, and we welcome individuals who share our commitment to shaping the future.

You’re a self-starter who loves diving into the unknown, collaborating on complex problems, and taking full ownership of results.

You excel at open, clear communication and see every piece of feedback as a springboard for growth—especially in a science and data-focused environment.

You’re motivated by creating real impact, particularly when it comes to advancing human health.

You strike a balance between independence and collaboration, knowing when to seek support or invite others to join in.

You’re confident in defending your ideas, while also valuing respectful, constructive debate as a path to better solutions.

You thrive in the dynamic atmosphere of a startup, constantly evolving your skill set and fearlessly applying what you learn.

What we offer

A full-time role with a competitive salary and equity options, reflecting our value in your expertise and potential.

An environment where you’ll collaborate directly with the founding team at a leading biosensor startup, gaining access to industry experts and thought leaders.

The chance to grow with us, including ample opportunities for leadership, career advancement, and exploration.

Travel to New York and other potential sites for R&D purposes.

The excitement of working on cutting-edge technology, shaping strategic decisions, and driving innovation at an early-stage venture alongside a superstar team.
