As a Firmware Engineer in Embedded OS team, you will work to bring the company’s in-house operating system to new generations of positioning receivers. We are a team of 6 engineers who love hacking on ARM chips at very low level. Our software boots up u-blox receivers and manages their resources. We are looking for a reinforcement, so if that sounds interesting to you, we’d love to talk!Our team designs, implements, tests, documents and provides support for the operating system. As hardware platform, we have embedded processors integrated with several RAM and ROM blocks, specialized signal processing acceleration units and other custom devices as well as standard peripheral blocks within System-on-a-Chip products.We work closely with several engineering teams to help bring up new chips, prototype and implement features, perform all kinds of testing and to optimize every aspect of our software.You will be part of an international multi-site team. In your daily work you’ll be using agile approach and the following tools to work together: Jira, Gitlab, wiki. You will mainly program in C but also will possibly use assembler for ARM (Thumb2) and C++. You will do a good deal of scripting in Perl, Python, shell (bash) and other languages like YAML and Groovy. You are able to set up and tweak Gitlab pipelines and runners, you know how to speak to Jenkins properly – at least, you are strongly interested in the topic and want to be doing that in your job. You have a good general understanding of digital electronics, can read schematics and use soldering iron. Rigging up some test HW is not a challenge but rather makes you smile. You like to use on-chip debugger, oscilloscope and logic analyzer.The position is in Tampere, Finland; Thalwil, Switzerland; or in Athens, Greece. Please state clearly in your application which location you are applying to.There shall be occasional travel to other u-blox sites within Europe.Your Responsibilities
