Physical-Aware Optimization

• Partner with backend implementation engineers on physical-aware synthesis, retiming, register balancing, pipeline optimization, and logic restructuring.
• Give RTL teams actionable feedback so designs are implementation-friendly from the outset.

Cross-Functional Execution

• Collaborate with architecture, RTL, verification, physical design, DFT, IP providers, and backend design services to drive rapid issue resolution.

Vendor Collaboration

• Work with external implementation partners to review QoR, timing, and area reports, and support constraint methodology and acceptance criteria.

AI-Enabled Engineering

• Apply AI tools to improve timing analysis, QoR regression, constraint generation, timing debug, report analysis, documentation, and engineering automation.

Required Qualifications

• 8+ years of ASIC implementation experience, including at least two successful tapeouts.
• Strong hands-on proficiency in synthesis and flow development.
• Proven experience closing timing on complex, multi-million-gate designs.
• Deep working knowledge of Cadence Genus and/or Synopsys Design Compiler.
• Strong SDC expertise, including constraint development and MMMC environments.
• A solid grasp of RTL design principles and implementation-friendly coding practices.
• Hands-on experience with advanced process nodes (7nm and below preferred).
• Strong Tcl and Python scripting ability for automation and flow development.
• Excellent debugging and root-cause analysis skills.

Preferred Qualifications

• Experience with AI accelerators, CPUs, or GPUs.
• Experience at 5nm and below.
• Familiarity with LPDDR, PCIe, or SerDes interfaces.
• Exposure to chiplet-based architectures and multi-clock SoC designs.
• Experience mentoring junior engineers or leading synthesis for a subsystem.

Leveling & Scope

While this role is currently posted at a specific level, we are a growth-oriented organization and are open to hiring at a more senior level for the right candidate. This job description is a focused but generalized overview of the role; specific responsibilities and impact expectations will be tailored to the experience and seniority of the final hire.

What Success Looks Like

Within one year, this person will have delivered predictable timing closure and high-QoR netlists for their assigned partitions, reduced implementation iterations through strong constraints and early RTL feedback, and made meaningful contributions to a scalable synthesis methodology that supports future ASIC generations.

Why Join Us?

• Play a key role in synthesis and timing closure for next-generation AI inference accelerators.
• Work at the cutting edge of AI hardware, directly influencing chips built to power frontier AI workloads.
• Grow your technical scope alongside an experienced, high-caliber implementation team.
