Sr. Physical Design Engineer

Job Title

Sr. Physical Design Engineer

Role Summary

Join Amazon Leo's ASIC team to define and implement digital SoCs for satellite and ground communications. The team designs modems, high-speed interfaces, embedded processors, and DSP solutions targeting advanced technology nodes.

The role focuses on back-end physical implementation strategies and execution for communications chips enabling low-latency, high-throughput links between Low Earth Orbit satellites and gateways.

Experience Level

Senior — typically 7+ years of experience in ASIC implementation and physical design.

Responsibilities

Deliver physical design implementation and methodologies for communications chips; collaborate with RTL, architecture, and cross-functional teams.

• Drive architectural feasibility studies and PPA trade-off analysis with RTL/logic designers.
• Lead IO/Core block implementation: synthesis, floorplanning, pin/bus planning, place & route.
• Perform timing closure (STA), congestion analysis, IR drop analysis, power/clock distribution design, and ECOs to achieve sign-off.
• Execute physical verification and prepare designs for tape-out.
• Develop and refine physical design methodologies and flows.
• Evaluate third-party IP and provide integration recommendations.
• Collaborate across multi-disciplinary and multi-site teams to deliver production-quality silicon.

Requirements

Must-have technical skills, compliance, and workplace attributes.

• 7+ years of ASIC implementation experience including synthesis, STA, DFT, and P&R for deep sub-micron nodes.
• Hands-on experience with floorplanning, placement, routing, timing closure, IR drop analysis, power/clock distribution, congestion mitigation, ECO and sign-off flows.
• Experience working directly with RTL/logic designers to resolve implementation and architectural issues.
• Ability to develop physical design methodologies and improve implementation flows.
• Experience evaluating and integrating third-party IP into digital top flows.
• Strong collaboration skills and experience working in cross-functional teams.
• Export control requirement: must be a U.S. citizen or national, U.S. permanent resident (Green Card), or lawfully admitted into the U.S. as a refugee or granted asylum.

Nice-to-have:

• Experience integrating RF/analog/mixed-signal blocks with digital top flows.
• Familiarity with UPF and low-power design flows.
• Experience operating in multi-site or distributed team environments.

Education Requirements

Bachelor's degree or above in Electrical Engineering, Computer Engineering, or equivalent technical field is stated as the baseline; Master's or Ph.D. in Electrical Engineering or a related field is listed as preferred. The posting also allows equivalent practical experience in lieu of a specific degree.
