Biosensors Research Intern - Electrochemistry

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 Tech Crunch 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.

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.

• 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

• 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

• 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

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

• You live and breathe integrity, tackling challenges with honesty and transparency
• 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…
