Embedded Projects
• Knowledge of Linux and Linux Kernel is a key to success.
• Get acquainted with Git + Gerrit for version control and code review;
Jenkins for continuous integration.
• Medical projects last long, development and test process should
comply with respective quality regulations norms. Tasks and schedule
are well defined and documented. Big “paperwork” overhead.
• While working for start-up projects be prepared to work hard on many
topics from different areas. The scope of work is undefined. Schedule is
tight.
• Automotive projects are trending now.
