About the Opportunity

We are seeking an experienced Senior Validation Technician to support the development, testing and validation of high-voltage power electronics systems for an innovative automotive engineering programme.

This is a hands-on opportunity for a technician with a strong background in environmental validation, electrical testing, instrumentation and troubleshooting.

Working closely with engineering and development teams, you will execute validation procedures, configure specialised testing equipment, analyse test results and support the resolution of technical issues throughout the product development lifecycle.

Key Responsibilities

Validation Testing & Technical Support

• Set up, execute and document development and validation tests on high-voltage power electronics systems.
• Conduct environmental testing, including thermal, vibration, humidity, corrosion and electrical performance testing.
• Record, analyse and document test results, preparing clear and accurate technical reports.
• Support root-cause investigations and troubleshooting of issues identified during validation.
• Work closely with engineering teams to support product development, testing requirements and technical issue resolution.

Instrumentation & Test Equipment

• Select, install and configure instrumentation to collect accurate test response data.
• Work with accelerometers, strain gauges, pressure gauges, thermocouples, voltage sensing leads and related instrumentation.
• Independently operate oscilloscopes, power supplies, multimeters, flowmeters and other laboratory equipment.
• Fabricate specialised electronic test equipment and test harnesses to support development and validation activities.
• Assist with the design and fabrication of mechanical fixtures, jigs and harnesses.
• Support testing involving thermal management equipment, including chillers.
• Maintain accurate test documentation, technical records and validation reports.
• Interpret electrical schematics, engineering documentation and manufacturers' datasheets.
• Communicate test results, technical findings and recommended corrective actions to engineering stakeholders.
• Support testing at external facilities when required.
• Work flexibly to accommodate testing schedules and development milestones.

Required Qualifications

• Technical degree in electronics, mechanics or a related discipline preferred, or equivalent relevant practical experience.
• At least 3 years of experience conducting environmental validation testing.
• At least 3 years of experience fabricating specialised electronic test equipment and test harnesses.
• Practical experience working with high-voltage electrical systems and a strong understanding of high-voltage safety procedures.
• Experience using oscilloscopes, power supplies, digital multimeters, flowmeters and related laboratory equipment.
• Ability to interpret electrical schematics and manufacturers' technical datasheets.
• Experience configuring instrumentation and supporting electrical or mechanical validation activities.
• Strong troubleshooting, analytical and technical problem-solving skills.
• Proficiency with Microsoft Word, Excel, PowerPoint and Visio.
• Excellent communication skills and the ability to collaborate with multidisciplinary engineering teams.
• Ability to work in a fast-paced product development environment.
• Willingness to work flexible hours when required and travel up to 20% to external testing facilities.

Additional Skills & Experience

The following experience would be advantageous:

• Working with chillers, thermal management systems or temperature-control equipment.
• Familiarity with common machine shop equipment and fabrication processes.
• Advanced soldering and electronic assembly or rework skills.
• Experience with Excel, SQL, Python, Jira or other Atlassian products.
• Experience in supply chain, manufacturing or product lifecycle management environments.
• Experience supporting engineering acceptance criteria, user acceptance testing and technical documentation.
• Experience querying databases, tracking performance KPIs or evaluating test data.
• Familiarity with ReactJS, GraphQL, web development, Figma or Lucidchart.

Why Apply?

• Competitive hourly rate: Up to $58.17/hour.
• Long-term opportunity: Initial 12-month contract.
• Innovative engineering: Support development and validation of high-voltage power electronics for advanced automotive systems.
