Job Description
• Lead the Porting Effort: Take Ownership of porting our existing ASIC RTL to the AMD Alveo V80
• Ensure the design is scalable, parameterizable, and optimized for the Versal HBM architecture
• Architect the RTL to support a unified codebase for both FPGA and ASIC targets
• Implement abstractions for memory, clocking, and resets that allow for seamless migration between programmable logic and custom silicon
• Optimize the CKKS FHE data path, including: NTT, KeySwitching, and Base Conversion to exceed the performance of state-of-the-art GPU implementations
• Use the FPGA platform as an iterative testbed to validate code and architectural improvements for future generations of our hardware
• Resolve the current team's challenges with debugging and toolchain experience
• Implement robust hardware debugging strategies using Vivado Hardware Manager, ILA cores, and Vitis emulation flows
• Take full responsibility for achieving timing closure on high density Versal designs
• Optimize the design for resource utilization (LUTs, DSPs, URAM) and power efficiency
• Architect and tune the Versal Programmable Network-on-Chip (NoC) to prioritize high bandwidth data movement between HBM2e and the PL fabric
• Initially lead backend and frontend engineering efforts, then assist in hiring and technical leadership of a multi-disciplinary team (Backend, Frontend, DevOps, Customer Support) to support growth from 5 pilot users to thousands of concurrent users
• Ensure the infrastructure meets enterprise-grade standards from day one, preparing the platform for HIPAA, SOC2, and GDPR compliance
Job Requirements
