Dragonfly Aerospace (DF) is a space technology solutions provider based in Stellenbosch, South Africa. DF offers commercial satellite solutions as well as a range of advanced engineering services, imaging payloads and operational solutions using space and related technologies. The highly experienced and motivated satellite engineering team develop and manufacture high-performance imagers and satellites, targeted at earth observation constellations.



The <Thermal Engineer (TE)> is responsible for leading the design, development and qualification of thermal engineering solutions to meet the needs mandated through product owners, clients and stakeholders such that it achieves outputs which meet validated requirements. The TE is responsible for performing mechanical services in accordance with the required company and departmental management standards and by providing it in an efficient, pro-active and synergistic manner.
All Thermal solutions within the organisation are to be produced in accordance with the standards set out by the Thermal Centre of Excellence (COE). The COE sets out its required standards for, amongst others, Thermal engineering principles, creating system tools, procedures, best practices and product/technology roadmaps.
Thermal solutions are produced for Space and Ground segments of spacecraft
engineering, which includes development for product lifecycle flight hardware models, ground support equipment, testing tools and jigs and in general the required creating systems.
The role of Line Manager takes full responsibility for the Mechanical Division and the management of the performance of all COEs (roles and functions) within it.
