The Company

Evonetix is a start-up company which is set to revolutionize de novo gene synthesis as needed to facilitate the fast-growing and incredibly exciting field of synthetic biology.  Our technology is based upon a novel silicon array, manufactured with semiconductor microfabrication techniques and capable of independent control of many thousands of miniaturized reaction sites, allowing massive parallelism of the DNA synthesis process.

Our community is a closely-knit multidisciplinary team of mechanical, electronic and software engineers, synthetic and surface chemists, physicists and biologists.

The Position

Evonetix is looking for a mechanical test engineer to work across our different workstreams to develop test rigs and protocols, and conduct tests, to inform our product development and manufacturing activities. These test engineering activities may be conducted in support of:

  • Key research and de-risking activities.
  • Life testing on key systems and sub-systems within the instrument
  • Proof of manufacturers’ data on key performance metrics, or where this data is not available, to enable informed component choices to be made
  • Design of specialist testing fixtures to enable the scientific team to conduct their research

The core areas of technical development that require extensive testing include:

  • Thermal management – managing the heat generated from the silicon chip so that it does not affect the microfluidic flow cell conditions
  • Fluidics – ensuring stable and consistent reagent delivery to the flow cell
  • Mechatronics – delivery of the DNA to a pre-defined well on a standard microtiter plate
  • Mechanism design – design of robust and intuitive interfaces that will require mechanical loading to complete electrical and fluidic circuits
  • Binary Assembly – working with the biologists in the development and evolution of the experimental set-up as elements of our DNA assembly process are optimised

You will be expected to take ownership for a number of discrete tasks that will run in parallel. This will include:

  • Working with the lead engineer/scientist on the requirements of the experimental set-up
  • Design and development of the test rigs
  • Implementing actuation mechanisms and data-logging solutions, working with other members of the engineering teams
  • Procurement of the standard and bespoke components
  • Assembly and de-bug
  • Conducting the relevant risk assessments
  • Working with the lead engineer/scientist to develop and complete suitable test protocols

This role requires someone who has a critical eye for detail and process.

Over time this role will include the development of test fixtures and manufacturing jigs for early production work.

Skills and experience

You will be degree qualified, or equivalent, in an Engineering discipline, with industrial experience focused in the area of testing.

Essential experience

  • Experience of having taken ownership for the design and development of test rigs and the diligent execution of robust test protocols
  • Knowledge of standard data logging platforms and data analysis tools
  • Knowledge of a range of prototyping and low-volume manufacturing methods

Desirable skills

  • Experience of using Python or similar to develop and run test scripts
  • Practicing 3D CAD user, preferably Solidworks
  • Experience of working within a quality management system, for example ISO13485
  • Background of working within life sciences or scientific instrument design
  • Experience of developing jigs and fixtures for manufacturing and assembly purposes


This opportunity comes with an attractive benefits package which includes a contributory pension, private medical care, life assurance as well as the opportunity to partake in the staff equity scheme.
