Job Description

Principal Mechanical Engineer | Thermal & Physics-Led Design | Deep Tech

Location: Sydney (Inner West)

Package: $160k - $200k + Super + Early Equity

The Challenge: First-Principles Engineering

This is not a standard machine design role. We are partnering with a heavily backed deep-tech startup who are moving from lab-proven tech to mass-manufacturable product in under 18 months. To do this, they need a Principal Mechanical Engineer who doesn’t just arrange components but understands the physics of what they are building.

The Role

You will take ownership of the mechanical architecture for high-energy reactor systems. This involves extreme heat, high voltage, and complex fluid dynamics.

  • Thermal & Fluid Mastery: You will design cooling systems and gas flow paths for high-power active components. You must be comfortable verifying designs with CFD and first-principles calculations.
