Candidates should have experience programming embedded software on a Power PC and testing embedded software using various test facilities, such as debuggers, probes, logic analyzers, and oscilloscopes. Furthermore, familiarity with DOORS and model-based development, either in SysML or UML, is required. A solid understanding of standardized bus systems and protocols, along with excellent analytical and design abilities (including review and critical analysis) is essential. We value candidates who are keen to work on novel products where the software is time and mission-critical, and who can communicate effectively with multiple stakeholders, including Systems Engineering, Electronics and Electrical, and Test and Validation. Responsibilities: As an Embedded ADA Software Engineer, you will develop real-time embedded software in ADA on a Power PC. Your responsibilities will include testing the embedded software, generating test requirements and scripts for unit, subsystem, and system-level testing on both host and target platforms. You will run tests, analyze results, and utilize target test facilities such as debuggers, probes, logic analyzers, and oscilloscopes. Furthermore, you'll be tasked with documenting the software effectively.
