Role: Research Assistant - SADI for Continuous AI Processing
Salary: Grade 6 - £31,236 - £36,636 per annum (pro rata)
Contract Type: Part Time (0.75FTE), Fixed Term for 6 months
Rewards and Benefits: 33 days annual leave, plus 9 buildings closed days (pro rata)
About the Role
The postholder will support the development and validation of SADI (Sum-Difference Accelerated Asymmetric Inner Product), an energy-efficient FPGA architecture for onboard AI inference in small satellites. The role will focus on translating the proposed architecture into a parameterisable VHDL implementation and evaluating its performance against conventional FPGA-based neural-network accelerators.
Key activities will include RTL/VHDL design, FPGA synthesis and implementation, hardware-level performance evaluation, and simulation of quantised neural-network workloads relevant to satellite Earth-observation applications. The researcher will contribute to benchmarking the architecture in terms of power consumption, logic utilisation, throughput and computational efficiency, with particular emphasis on SAR-based ship detection and, where appropriate, multispectral image segmentation.
The role will also involve integration and testing on the University's existing FPGA hardware, analysis of results, and preparation of technical documentation, architecture specifications and research outputs. The postholder will work closely with the project lead and relevant research and industry stakeholders to assess the potential for translation of the technology towards space-qualified FPGA platforms and future CubeSat applications.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you

Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The position provides an opportunity to develop practical expertise at the intersection of AI hardware acceleration, FPGA design, embedded computing and space technology, while contributing directly to the project's intended knowledge-transfer and impact objectives. The researcher will also support dissemination of the project's outcomes through conference participation, publications and the release of an open-source reference implementation where appropriate.
