Mechanical Design Engineer

We specialise in the design and manufacture of high‑quality fire detection solutions that protect people from fire in over 100 countries around the world.

At Apollo, we are always on the lookout for passionate people who want to make a difference and build a rewarding, challenging career within an internationally renowned fire detection company.

As a Mechanical Design Engineer, you will be responsible for delivering robust mechanical designs for high‑volume safety‑critical products across the full development lifecycle—from concept, simulation and prototyping through testing, verification, regulatory approval and production handover.

• Deliver robust, cost‑optimised mechanical designs on time and within budget.
• Work with Project managers to define implementation plans and deliver against them.
• Ensure all designs comply with quality, manufacturing and regulatory standards (including UKCA/CE and EN 54).
• Drive innovation in materials, sustainability and manufacturing processes.

• Check and approve mechanical designs, drawings and supporting documentation.
• Design high‑volume plastic injection‑moulded components and small metal fabrications.
• Create innovative mechanical solutions optimised for manufacture, assembly, reliability, sustainability and ease of installation.
• Ensure that existing designs are managed and supported through their lifecycle.
• Perform DFMEAs and drive corrective actions to eliminate risk.
• Prepare detailed 3D CAD models and 2D drawings using Solid Works.
• Use our PLM system to manage design data, change processes and control configuration management.
• Participate in prototyping activities, engineering evaluations and physical testing.
• Support regulatory and environmental testing with Labs and Compliance teams.
• Collaborate cross‑functionally with Electronics, Compliance, Software, Manufacturing and Programme teams.
• Experience defining mechanical architecture at the system level (interfaces, structure, materials).
• Execute simulations: FEA (static/dynamic), CFD, tolerance analysis, mouldflow or ray‑tracing.
• Familiarity with Model‑Based Definition (MBD).
• Knowledge of digital engineering methods and simulation automation.
• Understanding of modern automated and smart manufacturing technologies.
• Ability to support continuous improvement initiatives and introduce new technologies.

• Good communication skills – listening and giving honest, constructive feedback.
• Trusts and empowers staff to make decisions and be the best they can be.
• Practices a coaching/mentoring ethos.
• Builds and promotes teamwork.
