Mechanical Design Engineer

165637

Join our Engineering team in Tullamore and help develop the mechanical solutions that enable our products to move successfully from development into production. You will work across new product introductions and ongoing manufacturing, turning engineering challenges into practical, reliable solutions.

 

More about the role

As a Mechanical Design Engineer, you will work closely with Development, NPI and local Engineering teams to design, prototype, validate and industrialize mechanical solutions for our manufacturing environment. Your work will range from supporting new product launches to solving existing production challenges through the development of jigs, fixtures, test hardware and other production aids.

Tasks & Responsibilities

  • Design and develop mechanical engineering solutions, jigs, fixtures, production tools and equipment to support new product introductions and existing manufacturing processes.
  • Use CAD to create detailed 3D designs and drawings, taking solutions from initial concept through prototyping, validation and introduction into production.
  • Develop and evaluate prototypes using 3D printing and other appropriate manufacturing technologies.
  • Work closely with Development, NPI, local Engineering, Control & Test Engineering and other functions to deliver effective production solutions, including the integration of electrical components where required.
  • Create detailed component and machine specifications, drawings, BOMs and supporting documentation required for manufacturing and industrialization.
  • Collaborate with and manage external manufacturers and suppliers, supporting quotation, sourcing and delivery of components and solutions according to project timelines.
  • Troubleshoot production and process issues, identify root causes and implement robust engineering solutions while contributing to continuous improvement and process optimization.

 

More about you

We’re looking for a hands-on Mechanical Engineer who enjoys turning ideas into practical solutions and can take ownership of projects from concept through implementation. You are comfortable working autonomously while collaborating across multidisciplinary teams, and you can effectively manage priorities between NPI projects and manufacturing improvement activities in a fast-paced environment.

Essential qualifications

  • Around 3–5 years of experience in a similar mechanical design, manufacturing engineering, production engineering or NPI role.
  • Strong CAD experience, for example CATIA, SolidWorks or Inventor, with the ability to produce detailed 3D models and technical drawings.
  • Practical experience designing jigs, fixtures, production aids or other mechanical solutions for manufacturing environments.
  • Knowledge of manufacturing and prototyping technologies, particularly 3D printing, and experience designing for manufacture.
  • Ability to work independently, manage multiple priorities and deliver against deadlines while collaborating effectively as part of a wider engineering team.
  • Strong communication skills and the ability to work effectively with internal stakeholders and external manufacturers and suppliers.

Good to have qualifications

  • Experience with CATIA and/or Formlabs SLA 3D printing.
  • Knowledge of CNC machining, laser cutting or toolmaking/machine workshop processes.
  • Experience with automation or continuous improvement projects within a manufacturing environment.
  • Knowledge of acoustics or acoustic engineering.
  • Experience using Keyence 3D scanning technology or reverse-engineering mechanical components.
  • Project management skills and experience coordinating engineering activities with external partners.
