SUMMARY:
The Senior Signal Processing Engineer plans, implements, modifies, administers and verifies telescope correlator-beamformers and related signal processing systems for the telescope. They're responsible for the engineering processes throughout the engineering lifecycle of the signal processing subsystem, from contributing to the design and design reviews, taking the lead implementer role, and operations for the telescope. They must also possess a deep understanding and experience in Systems Engineering, Agile methodologies and DevOps processes. They must demonstrate a high to expert level of proficiency in Python, Git, Test-Driven Development, Test Automation & Continuous Integration. Senior engineers will be expected to guide and work with more junior team members to accomplish their tasks. Senior engineers are expected to be accountable for their deliverables. As part of the Operations team, they are expected to provide a senior level of Signal Processing systems support, able to investigate, diagnose and resolve complex issues with minimum guidance.
