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

SSTL designs and manufactures satellites for Earth observation, communications, navigation, debris removal, and exploration missions. The tech stack is heavily skewed toward aerospace engineering (Solidworks, MATLAB, Ansys, FPGA, VHDL) with enterprise SAP systems underpinning operations. Active hiring is concentrated in engineering roles, and a major SAP S/4HANA cloud migration is underway—replacing SAP Business One—while the team tackles recurring pain points around resource constraints, skill gaps, and technical debt across satellite payload and ground-segment development.
