The Principal Mechanical Design Engineer is responsible for leading aspects of mechanical design and development of our diagnostic platform and associated projects within DNAe.

It is expected that the Principal Mechanical Engineer will perform the following tasks with minimal supervision:

Leading technical development

Create, review, & guide others to develop requirements, designs, documentation, prototypes, test strategies, and analysis/test reports. Proactively identify technical/development risks and offer solutions. Provide clarity and decisiveness to the team, given limited information, while escalating decisions where necessary.

Development planning & reporting

Create and manage realistic project plans that may have a 6+ month horizon, and significant uncertainty/risks/issues. This includes defining scope, deliverables, strategies, timelines, resources and budgets. Also guide others to plan & manage less complex projects.

Managing external partners

Where applicable, recommend & work with external development partners to define scope/deliverables, track progress and budget, and ensure their output meets DNAe’s needs.

Technical Skills

• Significant experience in end‑to‑end development of complex milli/microfluidic consumables (for diagnostic systems or similar). This includes generating concepts; creating detailed CAD designs that address requirements and consider the needs of all stakeholders; design reviews; risk management; prototyping, testing & test rig design; and transfer to manufacture.

· Advanced skills in Solidworks computer aided design.

  • Significant experience in design for injection moulding.
  • Able to recommend suitable rapid prototyping techniques suppliers and test methods to match design & development goals.
  • Proficient with root cause analysis & resolving complex technical problems across disciplines.
  • Proficiency with FEA software (preferable Comsol) and hand calculations to analyze design performance.
  • Experience guiding more junior team members in the above and as a reviewer.
Non‑Technical Skills

• Experience developing within medical device development processes (ISO 13485); can guide others on good practice, identify gaps and suggest improvements.

• Able to discuss technical subjects with non‑technical stakeholders at a level of detail appropriate to them.

•(Preferred) Awareness of user, business, regulatory needs associated with sample‑to‑result.

•(Preferred) Basic understanding of assay development methodologies towards medical device designs.

• (Preferred) Experience overseeing third party work and deliverables.

Qualifications

It is expected that the successful candidate for this role is comfortable leading others, reviewing work, and thinking on a strategic/system level. They can draw on their experience developing similar systems to identify potential risks and solutions in the designs. They can question the brief they have been given and offer solutions to the 'job to be done' rather than addressing only the original ask.

They may be starting to think outside of project work towards business process improvements and line managing/career coaching others.

In order to fulfil this profile (as a guideline only) we believe candidates will typically need a higher degree in Mechanical Engineering or Design Engineering with 10+ years experience, at least 5 of which has been spent developing similar fluidics consumable products.
