Hello!

We're looking for an awesome Optical Instrumentation Engineer to join our team on our journey to revolutionize personalized medicine.

• 
  System design & assembly: Personally design, build, align, and calibrate novel optical analytical instruments (e.g., Raman, FTIR, fluorescence, scattering) from concept and component selection through to bench assembly and validation.

• Hands‑on prototyping: Solve optical/mechanical design challenges, design custom components/fixtures, and iterate rapidly to hit performance targets.

• Systems integration: Integrate optics with detectors/light sources, motion/actuation, electronics, fluidics, and software control to deliver fully functional prototypes.

• Testing & validation: Plan and execute experiments; analyze data to troubleshoot and optimize SNR, resolution, stability, dynamic range; own verification against specifications.

• Technical guidance: Serve as in‑house subject‑matter expert for spectroscopy—advise on component selection (gratings, filters, objectives, fibers, detectors), system architecture, and experimental methodology.

• Documentation & knowledge transfer: Maintain design files, BOMs, alignment procedures, and test reports; ensure reproducibility; support IP filings and hand‑off to manufacturing.

• Cross‑functional collaboration: Work closely with scientists, assay developers, data scientists, and QA/RA to ensure instruments meet biological, analytical, and regulatory needs.

• Safety & compliance: Uphold lab/laser safety; support design controls and documentation aligned with ISO 13485 (and related standards when in scope).

• Innovation: Track advances in spectroscopy/optics; prototype and evaluate new architectures to push platform capability.
  

This role is based in London and collaborates with teams in the UK and abroad.

• 
  An advanced degree (PhD or exceptional MSc) in Physics, Optics/Photonics, Nanoscience, or related engineering field.

• 3+ years industry experience designing, building, and operating complex optical systems from scratch in a lab environment.

• Deep, practical knowledge of Raman/FTIR/fluorescence/scattering instrumentation and how to build/align such systems.

• Strong hands‑on skills in opto‑mechanics, precision alignment, stray‑light control, and thermal/vibration management.

• Experience with data acquisition & control (e.g., Python/Matlab/C++/LabVIEW, pyVISA; motion stages/controllers).

• Plus: Familiarity with optical & mechanical CAD (e.g., Zemax/OpticStudio, SolidWorks/Onshape) and tolerance analysis.

• Plus: experience maturing prototypes toward production (DfX, manufacturability, reliability), and mentoring junior engineers/scientists.
  Advantageous: fiber optics, micro‑optics, microfluidics, laser safety, electronics, and signal processing/statistics.
  

Cultural Skills ✔️

• Builder’s mindset: hands‑on, resourceful, and relentless about quality.

• Low‑ego collaborator who elevates a multidisciplinary team.

• Mission‑driven and patient‑centered, comfortable in a fast‑paced startup.
