Reflex Aerospace delivers tailor-made, high-performance satellites to our customers an order of magnitude faster than anyone else.

Supercharged by a unique and revolutionary “algorithmic engineering” approach, Reflex Aerospace builds and sells tailored satellites to customers from earth observation and telecommunication domains.

Each delivered satellite stands out from the competition through its lightning-fast delivery time and highest quality “Made in Germany”.

Through smart standardization and automation of non-recurrent engineering and of the manufacturing, assembly, integration, and testing processes, Reflex is also able to undercut competition pricing while maintaining quality.

Multiple services are offered around the core product to reach more customers. These services include smart financing models, satellite subscriptions, and reselling of used platforms in orbit. All services aim to increase the number of sold platforms.

Reflex Aerospace is looking for an experienced power system engineer as a part of a cross-functional development team. You will have end-to-end responsibility for the development, integration, and testing of the electrical power sub-system.

Including solar panels, batteries, power control and distribution units (PCDUs), and other critical components. The power subsystem will be responsible for reliable power supply for all other subsystems of the satellite
