Technology Design Engineer in London

I'm currently working with a well-funded semiconductor start-up that's rethinking how AI accelerators are designed. Rather than relying on traditional, general-purpose architectures, the team is developing highly specialised silicon that maximises compute efficiency for modern AI workloads. Their innovative approach is already attracting significant industry backing and is challenging conventional thinking around accelerator design. As the business continues to grow, they're looking for an experienced ASIC Design Engineer to play a key role in developing the next generation of configurable AI processing architectures. You'll work across the full silicon lifecycle, helping transform architectural concepts into production-ready hardware while collaborating closely with Verification, Software and Systems teams. You'll be encouraged to challenge existing approaches, continually refine designs and contribute to the long-term technical direction of the product. Design and implement high-performance RTL for AI accelerator architectures Optimise existing RTL for performance, power and silicon area Evaluate architectural trade-offs and propose design improvements Work closely with Verification, Software and Systems Engineering teams throughout development Define and document micro-architectures, interfaces and design specifications Strong RTL design experience using Verilog or SystemVerilog Experience implementing high-performance digital or signal-processing hardware Scripting experience using Python, Tcl or similar Understanding of AI workloads or hardware acceleration concepts You're comfortable tackling unfamiliar challenges, enjoy working across multiple disciplines and are motivated by building innovative silicon rather than maintaining existing products. Join an ambitious semiconductor company at an exciting stage of growth Work on genuinely innovative AI hardware and accelerator architectures Help shape products that push the boundaries of compute efficiency
