As a Senior Embedded Software Engineer you will be part of the operating system team that belongs to an R&D division of u-blox’s Positioning product center. The team is responsible for providing reliable, scalable and secure real-time operating system for a wide variety of u-blox positioning products. We design, implement, test, document and maintain low-level platform software that boots up the system and manages its resources. That includes, amongst other things: startup, power management, task scheduling and communication, exception and interrupt handling setup, memory management, security services and device drivers.Our software runs on embedded processors integrated with several RAM and ROM blocks, specialized signal processing acceleration units and other custom HW, as well as standard peripheral blocks within System-on-a-Chip products. We work closely with several hardware and software teams to help bring up new chips, prototype and implement features, perform system-level testing and optimization. We also cooperate with architecture, product and application engineering teams, receiving feedback about and improving our software.You will be part of an international multi-site team. In your daily work you’ll be using Scrum and the following tools to cooperate: Jira, Phabricator, git, wiki. You will mainly program in C but also will use assembler for ARM (Thumb2), C++, Perl and Python where necessary. You have a general understanding of digital electronics and are able to use, e.g., a Lauterbach debugger and lab equipment for debugging purposes.The position can be based in Espoo or Tampere, Finland or in Athens, Greece. Please state clearly in your application to which location you are applying to.
There shall be occasional travel to other u-blox sites within Europe.Your Responsibilities
