Senior Embedded Software Engineer - Hardware

SumUp's Hardware Development team builds the payment devices that millions of small businesses use daily, and this role starts a new chapter by moving the in-house hardware onto the Android platform for the first time. The engineer supports system bring-up of a highly customised, security-first Android embedded platform, from bootloader through kernel to framework. Responsibilities include integrating and maintaining kernel modules and drivers such as power management and connectivity, contributing to build system integration, and debugging hardware and software issues at protocol level. Testing and validation to confirm platform stability and security before release are also part of the job. The work is done alongside hardware, software and QA engineers plus experienced embedded and secure processor leads, in an office-first setup in Berlin.
