C4 Engineering is an Australian engineering consultancy founded in 2017, specialising in technical services and project delivery support across aviation, systems engineering, communications, and emerging technologies. The firm works with government agencies and supplier organisations, covering the full project lifecycle from initial design through to certification and testing.
The consultancy's technical work spans a broad set of domains. In aviation, this includes avionics integration and airworthiness solutions for both crewed and uncrewed aircraft, with compliance across CASA, Defence Aviation Safety Regulations, and relevant Defence standards. Beyond aviation, C4 Engineering develops AI algorithms for autonomous underwater vehicles and takes on complex systems integration challenges across defence and communications environments.
In 2021, C4 Engineering launched C4 Space, based at Lot 14 in South Australia - the precinct established to anchor the country's space industry. The initiative supports the development of Australian space sector capability, helping organisations manage the technical and regulatory complexity of space missions.
