• Sustaining & Continuous Improvement: Lead and implement engineering changes (ECOs) to improve product reliability, performance, and cost, using structured problem solving and data-driven decision making.
• Failure Analysis & Field Performance: Drive root cause investigations for production and field issues, translating insights into robust corrective and preventive actions that enhance customer experience and product quality.
• Supply Chain Integration: Partner closely with supply chain to identify second sources, alternative components, and design-for-availability strategies, embedding resilience into product design.
• Technical Ownership of Released Products: Act as the technical authority for released electronic platforms, maintaining deep system knowledge, documentation, and design intent throughout the product lifecycle.
• Bridge to Innovation & R&D: Work hand-in-hand with R&D engineers on major platform updates and redesigns, ensuring continuity from legacy systems while supporting scalable, future-ready architectures.

• Strong foundation in analog and digital electronics, with hands-on experience in circuit design, testing, and troubleshooting.
• Comfortable working with lab equipment (e.g. oscilloscopes, multimeters, signal generators) to diagnose and resolve issues.
• Experience owning or supporting products through their lifecycle, ideally in a sustaining or product support environment.
• Practical experience with PCB design and schematic capture tools, and an understanding of design for manufacturability (DFM).
• Proven ability to lead structured problem solving, root cause analysis, and failure investigation, translating findings into robust corrective actions.
• Working knowledge of reliability engineering principles and how they apply to real-world product performance.
• Good understanding of component lifecycle, obsolescence, and supply chain considerations, with the ability to identify and implement viable alternatives.
• Familiarity with relevant regulatory and quality standards (e.g. CE, UL, IPC), and how they apply to electronic products.
• Exposure to embedded systems or firmware debugging would be beneficial.

Combination of lab, office, and manufacturing floor settings. The role may involve hands-on testing and interaction with hardware systems.

• A proactive engineer who takes ownership of outcomes, not just tasks.
• Comfortable operating across technical, operational, and commercial interfaces.
• Strong systems thinker with the ability to balance short-term fixes and long-term solutions.
• Collaborative, with the ability to influence across functions and levels.

• Competitive Remuneration Package including base Salary, performance related bonus structure, pension scheme, and other associated benefits.
