Product & Process Development Engineering Internship

We are looking for a hands-on engineering graduate (Bachelor’s or Master’s) to join our R&D team on a 6-month internship, with the possibility of extension. You will support design verification and engineering change requests (ECRs) on Callavid ®, our clinical- stage drug-device product for women, design and 3D print jigs and fixtures, and help manufacture samples for a clinical trial production run.

It is a great opportunity to gain real experience of medical device design controls within a quality management system.

• Planning and executing design verification activities in line with the Design Verification Plan
• Drafting test protocols, carrying out testing, accurately recording raw data and writing test reports
• Maintaining traceability between user requirements, technical requirements and verification tests
• Preparing test samples and fixtures, and coordinating with external test laboratories and suppliers
• Analysing test data against acceptance criteria, including basic statistics and sample size justification
• Recording and supporting the investigation of deviations and non-conformances

Jig, Fixture & Part Design

• Designing jigs and fixtures in Solid Works for test manufacturing, assembly and verification testing
• Producing parts in-house on our 3D printers, from print preparation to fit checks
• Iterating designs quickly based on testing and feedback, keeping models and drawings up to date
• Printing other parts as needed, e.g. prototype components, holders and workstation aids
• Ensuring jigs and fixtures used for verification are documented and controlled for repeatable results
• Raising ECRs with impact assessments on design, risk, verification, suppliers and regulatory docs
• Updating drawings, specifications, BOMs and procedures, and routing them for approval
• Maintaining the ECR log, chasing actions and supporting change review meetings
• Supporting updates to risk management documentation ( dFMEA / PFMEA) resulting from changes

Manufacturing & Equipment

• Supporting hands-on sample manufacturing for a clinical trial production run
• Maintaining workstations, 3D printer, air compressor and Mecmesin tester (training provided)

Documentation & General

• Keeping documents accurate and version-controlled (GDP) under an ISO 13485 quality system
• Communicating specifications and progress with suppliers for component procurement
• Supporting the R&D team with mechanical engineering and design work

• Completed Bachelor’s or Master’s in Mechanical, Biomedical, Manufacturing, Design or related Engineering
• Working knowledge of 3D CAD (Solid Works preferred)
• Very high attention to detail and a methodical approach to testing and documentation
• Clear and accurate technical writing skills
• Proficient in Microsoft Office, particularly Excel for handling and analysing data
• Well organised, able to manage multiple tasks and follow actions through with stakeholders
• Willing to take responsibility for equipment maintenance and to support hands‑on manufacturing

• Hands‑on experience developing a drug‑device combination product in a small, fast‑moving team
• Mentoring from experienced engineers, with the opportunity to extend beyond the initial 6 months

• Start date: Monday 30 November 2026, for 6 months (with possibility of extension)
• Location: Finchley Road, London NW3 5JJ
