About the Organisation

This organisation specialises in developing high-integrity, security-critical technologies where absolute reliability is essential. The engineering culture is built on excellence, innovation, and a commitment to exceeding customer expectations.

You'll be joining a multi-disciplinary team working on complex problems, disruptive security technologies, and advanced embedded solutions. The work involves supporting government and industry partners on projects involving secure systems, applied cryptography, and cutting-edge software and microelectronics.

About the Role

This is an exciting opportunity for software engineers-ranging from early-career developers to highly experienced specialists-to contribute to the design, development, and testing of innovative embedded products and cyber-security technologies.

The role involves analysing customer requirements, producing maintainable designs, participating in unit testing, contributing to code reviews, and creating documentation as required. Security, precision, and functional correctness will be central to your work.

You'll thrive in this role if you are detail-driven, collaborative, and motivated to develop high-integrity software guided by formal specifications. The work includes both independent problem-solving and close teamwork within an expert engineering group.
