Job Description

The Senior Software Developer (DSP) drives or supports the overall design and development of radio astronomy-focused Digital Signal Processing products and applications owned by the Data Processing & Pipelines Department within the Engineering & Technology Development Division. The Senior Software Developer brings expertise in software development, high-performance computing and GPGPU programming to enable development and delivery of data processing products and applications.
JOB DESCRIPTION

• Architectural design and/or implementation of digital signal processing (DSP) products, applications and/or algorithms for Radio Astronomy data processing systems that satisfy higher-level system functional and performance requirements
• Design of these products contains elements of software development, high-performance computing (HPC, GPGPU) and high-speed data transport
• Support analysis, definition, integration, verification and validation activities of DSP products at various system levels
• Development of software to control, monitor, debug and support operation of the developed products and applications
• Drive, follow and support the relevant Software Design Life Cycle and Systems Engineering processes for product development throughout the entire product or application lifecycle from conceptualisation through to decommissioning
• Support deployment, maintenance, upgrades, operation and decommissioning of developed products
• Manage, support and coordinate resources to ensure delivery of products within project constraints
• Participate in the generation of technical system and product-related documentation applicable to developed DSP products to support the delivery and handover of the Data Processing & Pipelines Group's products
• Drive and participate in Research & Development initiatives within the domain of expertise to develop novel ideas for future products and contribute to the overall continuous development of the group
