About us (Stealth mode)
We’re a stealth, VC-backed deep-tech startup building a next-generation molecular sensing platform, leveraging proprietary light-based sensing in a wearable form factor.
Our mission is to turn the body’s molecular signals into a continuous source of truth — unlocking real-time biochemical clarity for areas like fertility, inflammation, metabolic health, and recovery. Today’s wearables track proxies (heart rate, sleep, movement), but the biology that drives health still lives in episodic, invasive lab tests. We’re closing that gap.
The Role
We are looking for a hands-on R&D Lab Technician to support and accelerate core experimental work across surface chemistry, optical sensing, and microfluidics.
You will work closely with senior scientists and engineers to prepare experiments, run repeatable test workflows, and maintain experimental discipline across the platform. This is a foundational, high-impact role: your work will directly affect data quality, iteration speed, and system reliability.
This role is ideal for someone with hands-on industry lab experience who enjoys working across disciplines and wants deep exposure to cutting-edge biosensing technology in an early-stage environment. We particularly value candidates from medical device, diagnostics, or wearable sensor R&D backgrounds who understand the rigour and documentation standards those environments demand.
You will own
* Preparation and execution of workflows for sensor substrates, including cleaning, bioreceptor immobilisation, and testing.
* Support of biomolecular probe immobilisation, washing, and controlled incubation protocols.
* Preparation of buffers, reagents, analyte dilutions, and biologically relevant test fluids to defined quality standards.
* Support of stability, repeatability, and shelf-life studies of functionalised sensor surfaces.
* Handling and preparation of optical sensing chips and substrates under guidance from the photonics team. Such as cleaning the chip, basic optical alignment. There is no requirement on fabrication side.
* Support of benchtop experiments linking chemistry performance to optical readout (fluorescence, absorbance, or label-free methods).
* Preparation of test fluids and support of microfluidic cartridge testing, including flow, wetting, and lifetime experiments.
* Assistance with rapid prototyping workflows for microfluidic components (including 3D printing) and surface treatment processes.
* Maintenance of accurate experimental logs, batch records, and sample tracking across all work packages.
* Support of lab organisation, inventory management, consumables ordering, and equipment maintenance.
You’ll collaborate closely with leaders across photonics, microfluidics, clinical, and product and play a key role in bringing a genuinely cutting-edge wearable technology from first prototypes to pilot-ready systems.
The Person
Ideal requirements
* 1–3 years’ hands-on laboratory experience in an industry setting — ideally in medical devices, diagnostics, biosensors, or wearable health technology.
* Bachelor’s or Master’s degree in Chemistry, Biochemistry, Biomedical Engineering, Biotechnology, Biomedical Science, or a related field. Equivalent hands-on laboratory experience will be considered in place of formal qualifications.
* Comfortable working in a wet-lab environment with chemical and biological reagents.
* Methodical, detail-oriented, and disciplined in following and documenting experimental protocols.
* Organised and reliable, with strong time-management skills and the ability to support multiple work streams simultaneously.
* Curious and proactive, with an interest in how chemistry, optics, and microdevices interact.
* Motivated to learn and grow in a fast-moving R&D environment.
Nice to have (strong signals, not required)
* Experience with surface chemistry, biosensors, aptamers, antibodies, or bioconjugation techniques.
* Familiarity with fluorescence assays, ELISA-like workflows, or optical measurement techniques.
* Exposure to microfluidics, lab-on-chip devices, or wearable sensing systems.
* Experience working in a research, diagnostic, or biotech lab.
* Previous work in a regulated environment (ISO 13485, ISO 10993, or equivalent quality systems).
* Hands-on experience with rapid prototyping tools (3D printers, laser cutters, plasma treatment equipment).
Why work for us?
* High-impact, hands-on role: Your work directly supports the core experiments that define sensor performance, stability, and reliability. You’ll be close to the data and the hardware that make the platform work.
* Exposure to cutting-edge deep tech: Work on genuinely novel continuous biosensing technology at the intersection of surface chemistry, photonics, and microfluidics — far beyond routine lab work.
* Learn from exceptional scientists and engineers: Work day-to-day with senior experts across chemistry, optics, and microdevices, gaining rare cross-disciplinary experience.
* Early-stage influence: Join at a stage where experiments move the roadmap. Flat structure, fast iteration, and real visibility into how your work feeds into product decisions.
* Clear growth pathway: Competitive compensation and a defined progression path into Senior R&D Technician, Associate Scientist, or more specialised technical roles as the platform and team scale.
