About TUAL
TUAL is building the world’s first deployable charging network for large-scale enterprise customers.
We develop high-power EV charging systems combining battery storage, smart energy management, and ultra-fast DC charging — enabling electrification where grid constraints exist.
This is a fast-paced, product-led environment where engineering output directly shapes real-world deployment.

The Role
We’re looking for a hands-on Validation & Test Engineer to take ownership of testing across our charging and energy systems.
This role is highly practical — you’ll be physically building, wiring, configuring, and debugging systems to ensure performance, safety, and compliance.
You’ll work across electro-mechanical, electrical, and embedded systems, supporting delivery from concept through to deployment and helping establish scalable validation processes.
