Job Description: As a Senior Engineer in Modelling and Simulation, you will lead the development, integration, and operationalisation of simulation capabilities that enable Hivemind Mission Autonomy programs in Australia. You will architect, implement, and maintain high‑performance, real‑time and faster‑than‑real‑time simulation environments used by autonomy, perception, and systems engineering teams to design, test, and demonstrate cutting‑edge uncrewed aircraft mission autonomy. This role involves significant technical leadership, cross‑functional collaboration, and delivery of complex simulation frameworks that support both customer programs and internal R&D. You will directly contribute to scalable, operationally representative simulation ecosystems that underpin mission‑critical software development.
