Company: iLoF

Location: London

Job Description:

Full‑time

System design & assembly: design, build, align, and calibrate novel optical analytical instruments (e.g., Raman, FTIR, fluorescence, scattering) from concept to validation.
Hands‑on prototyping: solve optical/mechanical design challenges, design custom components and fixtures, and iterate rapidly to meet performance targets.
Systems integration: integrate optics with detectors, light sources, motion, electronics, fluidics, and software control to deliver functional prototypes.
Testing & validation: plan and execute experiments; analyze data to troubleshoot and optimise SNR, resolution, stability, dynamic range; verify compliance with 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, test reports; ensure reproducibility; support IP filings and hand‑off to manufacturing.
Cross‑functional collaboration: work with scientists, assay developers, data scientists, QA/RA to meet biological, analytical, regulatory needs.
Safety & compliance: uphold lab/laser safety; support design controls aligned with ISO 13485 and related standards.
Innovation: track advances in spectroscopy/optics; prototype new architectures to extend platform capability.

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, and scattering instrumentation.
Strong hands‑on skills in opto‑mechanics, precision alignment, stray‑light control, thermal and vibration management.
Experience with data acquisition & control (Python, Matlab, C++, LabVIEW, pyVISA, motion stages/controllers).
Familiarity with optical & mechanical CAD (Zemax/OpticStudio, SolidWorks/Onshape) and tolerance analysis.
Experience maturing prototypes toward production (DfX, manufacturability, reliability) and mentoring junior engineers/scientists.
Advantageous: fiber optics, micro‑optics, microfluidics, laser safety, electronics, signal processing, statistics.
Builder’s mindset: hands‑on, resourceful, relentless about quality.
Low‑ego collaborator who elevates multidisciplinary team.
Mission‑driven and comfortable with fast‑paced startup environment.

Private healthcare insurance (for employees; contractor benefits to be agreed).
Free coffee and snacks.
Weekly happy hours with food and drinks.
Flexible working hours; strong remote work culture.
Opportunity to work with world‑class team and contribute to transformative healthcare technology.
