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 revolutionise 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

• Design and develop microfluidic wearable platforms, including CAD modelling, lithography, and experimental setup


• Fabricate biosensor devices, including iterative prototyping in cleanroom environments, device validation, and preparation for scale‑up and manufacturing


• Run device characterisation experiments and keep track of performance on synthetic replicas, or during clinical studies


• Contribute to early‑stage R&D, collaborating with engineering leadership to define and refine future design iterations

What You Bring

The ideal candidate must have:

• Master’s degree with 1‑4 years of industry experience, or PhD with 0‑2 years of industry experience in microfluidics, microtechnology, materials science, biomedical engineering, nanotechnology, or a related discipline, with a focus on microfluidics and/or wearable or microneedle technologies


• Hands‑on experience in microfabrication cleanroom environments, including (but not limited to): silicon wafer processing, laser etching, photolithography, wet etching (HF, KOH), dry etching (RIE, ICP), microscopy, thin film deposition, e‑beam lithography, laser lithography, and any other relevant microfabrication technique


• Proven experience in microfluidic chip ideation and design, including core components such as mixers, metering systems, valves, etc


• Strong understanding of microscale fluid dynamics and flow control (pressure‑driven flow, capillary flow, paper wicking, etc.)


• Experience in mechanical testing and material characterisation of biological samples

Nice to have

• Experience with handling and flow of dermal interstitial fluid


• Experience designing wearable medical devices


• Knowledge of electrochemistry and biosensing principles


• Prior work in a start‑up or small company environment
