About the role
TEAM DESCRIPTION
SumUp's Hardware Development team builds the physical products millions of small businesses rely on every day, and this role sits right at the start of a new chapter: moving our in-house hardware onto the Android platform for the first time.

The team works closely with hardware, software, and QA engineers across the bring-up process, so this role offers a rare chance to shape a product's foundations while working alongside experienced embedded and secure processor leads.
