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.

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

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

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.

If our vision excites you, here are the qualities we look for:

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 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
