We are looking for an experienced Reliability Engineer to take ownership of reliability activities for advanced hybrid electronic systems operating in extreme, high-temperature environments.

The role will focus on proving and improving the reliability of high-temperature electronics
, identifying potential failure mechanisms and working with engineering teams to reduce risk and improve product performance throughout the product lifecycle.

You will work closely with electrical, mechanical, materials, manufacturing and quality engineers
, supporting the development of products used in demanding industries including aerospace, defence and oil & gas
.

This is a technically hands‑on role combining reliability engineering, failure analysis, materials, electronics and thermal management
.

• Develop and execute reliability test plans for high-temperature electronic hybrid designs.

• Conduct stress analysis, life testing and failure mode analysis.

• Plan and support Accelerated Life Testing (ALT) and Highly Accelerated Life Testing (HALT).

• Investigate failure mechanisms including thermal fatigue, electromigration and oxidation.

• Analyse test results and identify opportunities to improve product reliability.

• Work with laboratory and test teams using thermal chambers and specialist reliability test equipment.

• Work with engineering teams to build reliability into products from specification and design through to production.

• Lead or contribute to DFMEA, FMEA and Fault Tree Analysis (FTA) activities.

• Provide reliability input at key product development and design reviews.

• Recommend design changes to improve reliability and reduce product risk.

• Act as a technical authority on reliability matters within the business.

• Support the qualification of materials and components for extreme environments.

• Assess and recommend suitable ceramics, adhesives, alloys and electronic components.

• Support material trials, testing and requalification activities.

• Contribute to component and material obsolescence management.

• Analyse reliability and test data to identify trends and failure patterns.

• Apply reliability prediction and statistical techniques, including Arrhenius and Weibull analysis
  .

• Produce technical reports and presentations for internal and external stakeholders.

• Present reliability findings and recommendations to senior stakeholders and customers.

• Provide clear, evidence-based recommendations for improving product reliability.

• Ensure reliability activities comply with relevant industry and customer standards, including applicable MIL-STD requirements.

• Maintain knowledge of reliability testing standards, methods and emerging technologies.

• Research new reliability methodologies and identify opportunities to improve testing and product assurance.

• Work closely with design, manufacturing and quality teams to resolve reliability issues.

• Collaborate with suppliers, external laboratories and technical partners where required.

• Participate in technical reviews and continuous improvement programmes.

• Lead reliability improvement activities using structured problem-solving and methodologies such as Kaizen and Lean Six Sigma
