• Perform failure analysis, root-cause investigation, and implement corrective design actions.

Systems Integration

• Integrate electrical, mechanical, and software systems into final products.
• Ensure compatibility of hardware interfaces, wiring harnesses, and communication protocols.
• Support the transition from prototype to manufacturing, ensuring design-for-assembly and design-for-test principles are met.

Documentation & Compliance

• Generate and maintain design documentation, BOMs, and test reports.
• Contribute to risk assessments, design reviews, and compliance documentation.
• Support the preparation of technical files and validation reports for regulatory submissions.

Cross-Functional Support

• Collaborate with production, quality assurance, and field service teams to resolve product issues.
• Provide technical input for product improvements, cost reduction, and reliability enhancement.

Essential Requirements

• Bachelor’s or master’s degree in mechanical, electronics, or electromechanical engineering, or a related field.
• 3+ years of experience in a multidisciplinary engineering role, ideally in an R&D environment.
• Proficiency in systems integration and validation involving mechanical, electronics, and software components.
• Strong knowledge of design tools (e.g., CAD for mechanical, EDA tools for electronics, etc).
• Experience with embedded systems, microcontrollers, and interfacing hardware and software.
• Demonstrated ability to develop and execute test protocols for system validation.
• Excellent problem-solving skills and the ability to work both independently and collaboratively.
• Ensure project and individual timelines are consistently met in collaboration with the line manager.

Preferred Skills

• Familiarity with C and embedded firmware programming and troubleshooting.
• Familiarity with Linux OS environments.
• Hands-on experience with rapid prototyping techniques (e.g., 3D printing, PCB fabrication).
• Practical experience conducting customer-facing testing.
• Knowledge of calorimetry in chemical or battery industries.

Benefits and Package:

• Annual salary dependent on skills, qualifications and experience
• Bonus based on performance
• 4-days week eligibility at the end of the probation period
• EV salary Sacrifice Scheme eligibility after 1 year seniority
• Share Incentive Pan
• Pension scheme, 5% matched contribution
• Life Cover
• Holidays – 25 days + bank hols (plus seniority days)
• Training plan available
