About the position
PURPOSE:
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 to 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 organisation's 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.
KEY RESPONSIBILITIES:
- Implement and verify correlator-beamformers and related signal processing systems.
- Contribute to systems engineering and Operations documentation refinement
- Support users, operators, as well as the implementation of releases, system changes and fixes.
- Work with the Correlator Beamformer construction teams
- Work with system/array integration team, supporting correlator integration and testing
- Be an integral member of the Computing and Software team, as a senior technical specialist that supports the establishment of signal processing and correlator operations
- Establish and maintain a professional relationship with organisation's Digital Signal Processing team
- Participate in project management and activity management activities.
- Attend relevant training/courses to gain experience and improved knowledge.
- Research new technologies, methods, or approaches, with the purpose of utilizing them within the organization.
- Participate in innovation and technology development initiatives.
- Mentor and educate more junior engineers as and when required
