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
- Own the mechanical design and development of plastic components for a wearable device and pump system.
- Design robust injection moulded plastic parts from concept through to production release.
- Produce high-quality 3D CAD models, assemblies and engineering drawings to manufacturing standards.
- Perform tolerance analysis and tolerance stack-ups to ensure robust product performance and manufacturability.
- Create detailed design specifications, engineering requirements and mechanical architecture documentation.
- Develop, refine and execute verification test methods to evaluate product performance and reliability.
- Plan and conduct engineering testing, analyse results and iterate designs based on data.
- Lead mechanical investigations, identify root causes of failures and implement effective design improvements.
- Apply human-centered design practices by conducting human factors studies, usability evaluations, and user research sessions - translating findings into actionable product and design improvements.
- Work closely with external suppliers and manufacturing partners to develop production-ready components.
- Specify and qualify bought-in components and work with suppliers to integrate them into the product.
- Collaborate closely with electronics, systems, quality, manufacturing and industrial design teams.
- Balance technical performance, usability, reliability, manufacturability and cost throughout the design process.
- Contribute to early-stage R&D, collaborating with engineering leadership to define and refine future design iterations.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
