Advanced Packaging & Power Delivery Senior Engineer in Bristol

As a Senior Advanced Packaging & Power Delivery Engineer at Axelera AI, you will play a pivotal role in shaping the silicon and packaging architecture of next‑generation AI accelerators. You will own power‑delivery design across the full stack – from on‑die power grids to package and PCB PDN – and bring deep expertise in advanced packaging technologies to help us scale from today’s products to tomorrow’s multi‑chiplet, 3D‑integrated systems. Working within our R&D Custom Design team and collaborating closely with Silicon Engineering and AI Integrated Systems, you will be at the intersection of analog design, packaging innovation, and product delivery – with real ownership and direct impact on the chips we ship.

Key Responsibilities

• Own power‑delivery design end to end, from on‑die power grids to package and PCB PDN design and analysis.
• Lead advanced packaging architecture decisions for 2.5D/3D stacking, multi‑chiplet integration, and interposer/substrate co‑design.
• Perform SI/PI verification and sign‑off across the full stack, ensuring power integrity and signal integrity targets are met.
• Collaborate with the AIIS and Silicon Engineering teams to align power delivery and packaging solutions with product and silicon requirements.
• Support thermal and integration reviews for current and future products.
• Develop and maintain power‑delivery methodology, flows, and design guidelines within the Custom Design toolchain.
• Identify and mitigate single‑point‑of‑failure risks in SI/PI workstreams; mentor and grow the team's packaging expertise.
• Engage with external partners, substrate/interposer vendors, and OSAT houses to co‑develop advanced packaging solutions.

Qualifications Required

• Bachelor’s or Master’s degree in Electrical Engineering, Microelectronics, or a related field; PhD is a plus.
• 7+ years of experience in power delivery and/or advanced packaging design in a semiconductor or deep‑tech environment.
• Demonstrated expertise in on‑die power grid design and package/PCB PDN analysis.
• Hands‑on experience with 2.5D and/or 3D IC packaging technologies, multi‑chiplet integration, and interposer/substrate co‑design.
• Proficiency with industry‑standard EDA tools for power integrity, PDN simulation, and package design.
• Ability to work cross‑functionally and communicate complex technical trade‑offs to diverse stakeholder groups.
• Strong written and spoken English communication skills.

Nice to Have

• Experience with SI/PI verification and sign‑off methodologies.
• Familiarity with thermal modeling and co‑simulation for integrated packages.
• Exposure to AI accelerator or custom ASIC design flows.
• Experience collaborating with OSAT partners, substrate vendors, or research institutes (e.g., imec).
• Knowledge of advanced node custom and analog design practices.
