• Produce engineering documentation including designs, analyses, compliance reports, and security, safety, and service-related artefacts.

• Conduct technical assessments, trade studies, and feasibility evaluations to support solution development.

• Contribute to the delivery of integrated solutions using COTS and bespoke technologies.
