Senior Logical Design Engineer

Job Title

Senior Logical Design Engineer

Role Summary

Join the digital design team to develop and optimise RTL for high-performance, power-efficient chips targeting very high-throughput AI inference. You will own RTL modules from specification through delivery and work closely with verification and physical-design teams to enable successful tapeout.

This role is hands-on and cross-functional; some candidates may require additional eligibility checks due to UK, US and other international export control regulations.

Experience Level

Senior-level — 6+ years of experience in digital design, RTL development, or related roles.

Responsibilities

Deliver RTL designs and ensure they integrate correctly into the wider system.

• Develop and maintain clear RTL specifications and module interfaces.
• Implement complex design modules with focus on performance, power, and area.
• Plan, partition and own discrete design work packages from definition to delivery.
• Collaborate with verification engineers on simulation and formal verification to ensure functional correctness.
• Work with physical design and other cross-functional teams to ensure seamless integration.
• Document design methodologies, interfaces, and maintain coding standards and best practices.

Requirements

Key skills and experience required; concise and pragmatic.

• 6+ years of experience in digital design or RTL development for high-performance systems.
• Proven track record delivering RTL for high-performance and power-sensitive designs.
• Familiarity with advanced digital design concepts such as pipelining, clock-domain crossing, and power gating.
• Experience with high-speed or low-power design methodologies.
• Strong analytical problem-solving skills and attention to detail.
• Effective written and verbal communication for cross-functional collaboration.

Education Requirements

Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, Computer Engineering, or a related field.
