Semiconductor Device Engineer

entX is a pioneering company creating next-generation power and heating solutions for space and Defence missions. Our GenX betavoltaic generator delivers long-lasting, maintenance-free electrical power for autonomous Defence platforms, enabling them to stay "on station" far longer than traditional systems allow. Similarly, our innovative radioisotope heating unit (RHU) keeps spacecraft and payloads warm during extreme cold, offering a lightweight, cost-effective alternative to bulky batteries or complex plutonium-based heaters. These technologies unlock new possibilities for extended missions—whether it's keeping a remote sensor alive for months or ensuring a lunar lander survives the harsh temperature swings of the Moon.

entX is seeking a Semiconductor Device Engineer with 3–5 years of hands-on experience to help shape the future of nuclear-powered energy systems. You'll play a key role in advancing entX's GenX betavoltaic generator—a long-life, maintenance-free power source designed for autonomous defence platforms and space missions. Working across R&D, testing, and product validation, you'll contribute directly to systems that redefine endurance, efficiency, and reliability in extreme environments.

If you're motivated by purpose-driven technology and eager to apply your semiconductor expertise to world-first innovations, we want to hear from you.

• Drive the investigation and optimisation of semiconductor devices for betavoltaic energy conversion, focusing on junction behaviour, charge transport, and current capture to enhance performance, troubleshoot issues, and advance fundamental device understanding.
• Contribute technical expertise to translate device concepts into scalable processes, ensuring manufacturability, reliability, and continuous improvement in fabrication methods, while supporting integration into entX's next-generation power systems. Develop and support design outputs (including FMEAs and other technical documentation) to ensure robustness, traceability, and alignment with manufacturing needs.
• Plan, conduct, and coordinate validation activities to demonstrate that devices and processes meet defined specifications and performance targets.
• Ensure products and processes adhere to applicable regulatory, safety, and customer requirements throughout development and production.
• Identify opportunities for novel device concepts and process improvements, raising potential patents with management and collaborating with patent attorneys on filings.

Essential

• Demonstrated experience in the application of semiconductor device physics in an applied or industrial setting.
• Project collaboration experience in a commercial environment.
• Must exhibit a high level of analytical and decision-making skills and ability to work in a team environment
• Good communication skills, both written and verbal.

Desirable

• Experience in handling, manipulation or modification of radioactive isotopes
• Experience in research and translation of research outputs into a commercial application.
• Experience in developing and applying radiation-transport and simulation models.
• Basic understanding of quality, regulatory and safety requirements (i.e. radiation safety, EPA-SA/ARPANSA regulations, quality systems)

Essential

• Degree qualification in physics, chemistry, materials science or another relevant technical field
• Be eligible for application to Security clearance level 2, NV 1 (Negative Vetting Level 1) under the Australian Government's Protective Security Policy Framework

Desirable

• Certification in nuclear engineering, radiochemistry or another relevant technical field is highly desirable
• Possession of a current Baseline or NV1 security clearance

Please ensure your application clearly addresses the key skills and experience, qualifications and certifications as outlined above.
