Description
:
Position: Senior Design Engineer – Product Optimisation (Terex screener Platforms)
Location: Dungannon
Hours: 39.75 per week
Reports to: Engineering Director
Role Summary
This role focuses on improving existing mobile screeners through practical, engineering‑led design optimisation, while also contributing to new product development from the earliest stages.
You will work on machines that are already operating in the field, identifying and delivering improvements to performance, reliability, manufacturability, and cost. Proven improvements are then embedded early into new product concepts and platform developments, ensuring future machines benefit from real‑world learning.
The role combines structured product improvement projects, hands‑on design engineering, and early‑phase NPPD involvement, offering continued exposure to creative design work while delivering tangible product enhancements.
The role is well suited to a Design Engineer who enjoys improving mature products, or a Manufacturing / Operations Engineer looking to move into a more design‑focused role while applying strong build, quality, and process knowledge.
Main Duties & Responsibilities
1. Analyse field performance, warranty data, build issues, and cost drivers on current mobile screening machines
2. Redesign components and assemblies to simplify build and assembly, improve manufacturability and serviceability, increase reliability and durability, and reduce unnecessary complexity
3. Apply DFM/DFA principles to improve existing machines and influence future product architectures
4. Collaborate with manufacturing, supply chain, and suppliers to convert improvement ideas into robust, production‑ready designs
5. Support prototype builds, trials, and validation activities on live machines
6. Own engineering changes through design release and introduction into production
7. Contribute to new product development by embedding learning from existing platforms into early concept decisions, system layouts, and design standards
Experience & Qualifications:
8. Degree (or equivalent experience) in Mechanical Engineering, Manufacturing Engineering, or a related discipline
9. Experience working in design engineering, manufacturing engineering, or product development environments
10. Demonstrated experience improving existing products through redesign, simplification, or engineering optimisation
11. Practical understanding of manufacturing and assembly processes, including tolerances and production constraints
12. Experience applying DFM/DFA principles to influence design decisions on current products or during early development phases
13. Experience using 3D CAD and engineering design tools, or a strong interest in developing advanced design and digital validation skills
14. Exposure to new product development activities, with an interest in influencing designs from early concept through to production
15. Experience with mobile machinery, heavy equipment, hydraulics, or structural assemblies is beneficial, but not essential. We value engineers who can think critically, challenge existing designs, and translate practical insight into robust engineering solutions.
Knowledge, Skills and Abilities:
16. Strong mechanical engineering fundamentals, with the ability to translate real‑world issues into practical design solutions
17. Confidence working with complex mechanical assemblies and understanding how design decisions affect build, service, and long‑term reliability
18. Ability to balance detail‑focused design work with higher‑level system thinking, particularly when influencing early product concepts
19. Evidence‑based problem‑solving approach, using data from field performance, build experience, or testing to guide decisions
20. Ability to work effectively across design, manufacturing, supply chain, and supplier teams
21. Comfortable taking ownership of engineering problems and driving them through to resolution
22. Pragmatic, hands‑on mindset with a strong interest in seeing designs built, tested, and operating in the field
23. Clear and effective communicator, able to explain technical decisions and trade‑offs without unnecessary jargon
24. Curious and improvement‑driven, motivated to embed learning into both current products and future designs
