* Background as a Senior Technician or Degree in Electrical, Electronic or Automotive Engineering
* Experience in validation, verification or test engineering within EV, energy or industrial systems
* Strong understanding of system‑level validation and test methodologies
* Hands‑on experience with embedded systems and communication interfaces
* Proven ability to build, wire and configure test setups and prototypes
* Experience analysing test data and producing clear outputs
* Familiarity with safety risk assessment in a test environment
* Comfortable working in a fast‑paced, evolving environment
Desirable:
* EV charging systems or protocols (OCPP / OCPI)
* Battery systems or power electronics
* IoT systems, telemetry or cloud integration
* Test automation or scripting (Python or similar)
* Exposure to regulatory compliance and certification testing
Who You Are
* Hands‑on and practical – enjoys building and solving real engineering problems
* Self‑sufficient – able to take ownership in a process‑light environment
* Detail‑focused – strong approach to documentation, traceability and quality
* Adaptable – comfortable working in a scaling, fast‑moving business
Why Join TUAL?
* Work on cutting‑edge EV charging and energy systems
* Play a key role in shaping validation capability as the business scales
