Satlink builds satellite and IoT hardware for fisheries tracking and ocean sustainability. The tech stack is heavily embedded-systems focused (STM32, FreeRTOS, GNSS, GPS, 4G/LoRa/Bluetooth radio) with Python and Linux as the systems layer — typical of companies deploying hardware at scale across remote ocean regions. Engineering hiring now outpaces sales 5:1, and active projects show heavy investment in R&D validation and automated testing, suggesting Satlink is scaling production and reducing manual QA bottlenecks.
