A Division of Aquaffirm

Ref: BNC/MFR/0423NS

 Salary Range: £37,000 – £45,000 commensurate with experience

 Manufacturing Lead, Electrochemical Sensors

AquAffirm is developing the world’s first portable, digital, cloud-connected sensors for measuring some of the world’s most debilitating water contaminants, with a first application to measure arsenic, which affects over 140 million people in 70 countries.

AquAffirm provides a dynamic and collaborative environment for researchers and engineers to excel at their careers. Our globally-recognized scientists and engineers pursue innovation to help solve complex challenges in the water sector, which range from water reuse optimisation software through to point-of-use testing solutions and contaminant removal technologies.

AquAffirm has one full-time Engineer/Scientist role as Manufacturing Lead, Electrochemical Sensors available. Acting as part of the AquAffirm product development team the post-holder will join a highly motivated group working to develop an innovative and award-winning enzyme biosensor for measuring arsenic contamination levels in drinking water.

The successful applicant will have a strong background in bio-/chemical-sensors with experience in manufacturing electrochemical sensors. Industrial research and development experience in establishing manufacturing processes would be beneficial. Additionally, the successful candidate will have excellent verbal and written communication skills and will have an ability to work both independently and as part of a team.

The role requires use of the candidate’s own initiative to ensure that all projects are delivered on time, within the scope and in required quality. Confidence in working in a busy, business-focussed environment with highly-skilled and motivated individuals, coupled with the ability to handle pressure on occasions is essential. The appointment will start as soon as possible and is subject to receipt of satisfactory references.

  • Facilitate in the discussions with external vendors and subcontractors;
  • Facilitate in the development of electronic instrumentation to interface sensors;
  • Oversee use of existing electronic and optical spectroscopy instrumentation and custom software for sensor characterisation and measurement;
  • Prepare progress reports on sensor development and manufacturing as required;
  • Work with Chief Scientist and project manager to ensure undertaken laboratory work is in accordance with the company’s health and safety policy;
  • Review of relevant literature where required;
  • Report to project manager;
  • Carry out any other duties within the scope, spirit and purpose of the job as requested by AquAffirm.


 PhD in Electrochemistry or biosensors would be beneficial; industrial experience in sensor manufacturing is essential.
