Surrey Satellite Technology Ltd (SSTL) Tech Stack

Small-satellite design and manufacturing for Earth observation and space infrastructure

Aviation and Aerospace Component Manufacturing Guildford, Surrey 201–500 employees Founded 1985 Privately Held

SSTL designs and manufactures complete small satellites for Earth observation, communications, navigation, and in-orbit servicing missions. The tech stack reveals heavy investment in SAP enterprise systems (S/4HANA Cloud, Datasphere, Business One, Concur) alongside specialized aerospace engineering tools (MATLAB, Ansys, Solidwork, STK, Nastran, FPGA/VHDL). Hiring is heavily weighted toward senior and mid-level engineers—18 of 21 active roles—signaling either a major mission ramp or intentional shift away from junior-heavy development toward experienced spacecraft system integrators.
