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 The Role (Internship)
We are looking for a Biosensors Research Intern (Electrochemistry) to support our electrochemical biosensor R&D team, with a focus on aptamer-based sensing and small-molecule assay development. This role is designed for an intern: you’ll work on well-defined experiments, learn our lab workflows and electrochemistry stack, and contribute data and documentation that moves projects forward.
This is a full-time, in-person internship primarily based in London.
What you'll do
Some examples of what you might do:
- Support the design and execution of electrochemical experiments (e.g., voltammetry, impedimetry, chronoamperometry) under guidance
- Prepare buffers/solutions, handle samples (including biofluids where appropriate), and maintain good lab practice
- Assist with electrode cleaning and basic surface functionalisation steps following established protocols
- Run assay optimisation experiments (e.g., concentration ranges, incubation times, blocking conditions) and record results rigorously
- Carry out routine characterisation and quality checks on sensors and reagents, flagging anomalies early
- Contribute to Python-based data analysis and plotting (training provided as needed) and help maintain tidy datasets
- Help draft and update Standard Operating Procedures (SOPs), experiment templates, and lab documentation
- Present progress in short weekly updates and collaborate closely with chemists, biologists, engineers, and data scientists

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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You Bring
Essential
- Currently pursuing (or recently completed) a bachelor’s or master’s degree in Electrochemistry, Analytical Chemistry, Biochemistry, Chemical/Materials Engineering, or a related discipline
- Comfortable in a wet lab environment with strong attention to detail, safety, and reproducibility
- Foundational understanding of electrochemistry and enthusiasm to learn biosensing applications
- Some hands-on experience with at least one of: electrochemical measurements, surface chemistry, assay development, or analytical methods
- Strong organisation and note-taking skills (you keep experiments traceable and data interpretable)
- A proactive, creative, problem-solving mindset and willingness to ask good questions
Nice to have:
- Prior exposure to aptamers or other biorecognition elements (even through coursework or a thesis project)
- Familiarity with the microfabrication techniques and microfluidic wearable platforms, including CAD modelling, lithography, and experimental setup
- Familiarity with Design of Experiments (DoE), basic statistics, or Python scripting for data analysis
- Experience working with complex matrices (e.g., serum, saliva, urine) or sample preparation
- Experience with SPR, molecular docking, or structural modelling
- Experience with Python, R, or MATLAB
