• Mentor and coach Physical Design engineers, supporting capability development across the team.
• Review and approve block‑level physical design deliverables before integration.
• Lead technical reviews, debug sessions and closure activities.
• Support recruitment activities and contribute to building a world‑class Physical Design team.
• Represent Aion Silicon at universities, conferences and industry events, sharing technical expertise and promoting innovation.
• Ensure the team remains at the forefront of industry methodologies, tools and advanced‑node technologies.

What We\'re Looking For

• 10+ years of Physical Design experience with a proven track record of full-chip delivery.
• Strong expertise in advanced technology nodes, including 7nm, 5nm and below.
• Experience delivering multiple complex SoC or ASIC tape‑outs.
• Demonstrated leadership experience mentoring and developing engineers.
• Strong customer engagement and stakeholder management skills.
• Excellent communication skills with the ability to influence technical direction across multiple teams.
