Company: Octagon Group

Location: Waterbeach

Posted: May 15th, 2026

Key Responsibilities

• Support design processes from the mechanical side, using engineering knowledge combined with tools such as DFMEA to ensure DFM/DFA is considered throughout the design phase

• Support mechanical workstreams within NPI projects, ensuring readiness for build and scale, and supporting the transition of products through to customer delivery Page 2 of 3

• Work alongside electrical and software engineers within the NPI team to design and develop electromechanical test jigs that optimise production throughput and ensure product quality

• Work alongside the manufacturing team to define and document mechanical build procedures, assembly instructions, and production workflows to establish repeatable manufacturing

• Provide a hands-on approach during NPI builds, supporting root cause investigation and resolution of mechanical failures or assembly issues within the engineering change process (ECN) framework

• Drive improvements in manufacturing readiness by identifying and implementing opportunities to streamline mechanical assembly processes and reduce build time

• Work alongside the quality department to support non-conformance investigations, and product quality improvements during NPI phases • Contribute to the development of the new NPI team’s standards and processes.
