Due to growth we are looking for a Senior Optical Engineer to join our business on a permanent, full-time basis. This role will be based at our Scion House site in Stirling and you will be part of the assay platform and instrument development teams. The role will be responsible for driving the development of the optical systems associated with the LumiraDx Point of Care (POC) instrument design, including fluorescence measurement based systems from the lab-based prototype stage to high volume manufacture design transfer.

Role & Responsibilities

  • Concept generation of optical sub systems, including fluorescence measurement systems, relevant to the required performance, form factor, robustness and cost criteria associated with the LumiraDx Instrument development activities.
  • Modelling and simulation of optical systems and associated critical to quality design consideration inputs, ouputs, design variables and tolerances.
  • Creation of detailed design specifications based on simulation, prototype testing, characterisation and product requirements.
  • Define optical performance specifications for the optical detection system, working closely with engineers  and scientists across disciplines to maximize system performance.
  • Design and execute optical experiments to demonstrate, characterise and verify the performance of optical systems including fluorescence measurement systems.
  • Analysis of experimental data of new and existing designs, and creation of associated design study reports, including application of signal measurement and processing techniques to determine and optimise system signal to noise.
  • Work across instrument development and assay development teams to resolve system performance anomalies.
  • Formulate robust calibration schemes methods appropriate for implementation as part of a high volume manufacturing system solution.
  • Work with external vendors to specify and realise both custom and off the shelf optical components.
  • Responsible for ensuring the design complies with regulatory standards.
