Job Description: About the Role As a Senior Physical Design Engineer, you will be a core technical contributor responsible for the physical design implementation of our next-generation IPs. In this role, you will implement RTL2GDS ensuring the architecture and design achieve their peak physical potential. We are looking for a "full-stack" physical design engineer who is deeply curious about the logic they are building. You should be the type of engineer who thrives at the convergence of microarchitecture and physical layout, enjoying the challenge of analyzing how an architectural datapath affects timing closure and how to push the boundaries of Power, Performance, and Area (PPA). Key Responsibilities End-to-End Implementation: Own and execute the complete physical design flow (Synthesis, Floorplanning, P&R, Signoff) for major sub-systems and diverse IP blocks, ensuring they meet or exceed aggressive targets for PPA. Architectural & RTL Co-Optimization: Partner with RTL and Architecture teams from early-stage design to signoff. Identify physical and structural bottlenecks early—such as routing congestion in complex crossbars, dynamic power hot-spots in execution units, and interconnect span limits—and collaborate on microarchitectural or structural solutions to overcome them. Cross-Product PPA Execution: Apply advanced physical design techniques customized to the unique demands of different design classes. This includes implementing extreme leakage/dynamic power efficiency for edge IPs, rigorous reliability and redundancy structures for automotive standards, or maximizing bandwidth and throughput for high-speed fabrics. Technical Ownership: Take ownership of complex implementation challenges, contribute to the improvement of flows, methodology, and automation, and assist in mentoring junior engineers while promoting best practices. Requirements - What you’ll bring Experience: 4+ years of hands-on physical design experience on advanced process nodes (7nm and below preferred). IP Implementation Expertise: Solid experience with the physical implementation of at least one major IP domain (such as CPUs, high-speed interconnects/fabrics, cache/memory hierarchies, or specialized accelerators) and a proven ability to adapt to new logic classes. Co-Design Mindset: Understanding of the interplay between physical implementation and microarchitecture, coupled with the curiosity to learn and adapt to different product architectures. Tool Proficiency: Strong proficiency with industry-standard EDA tools—specifically Synopsys (Fusion Compiler, PrimeTime) and/or Cadence (Innovus, Tempus) implementation and sign-off suites. Advanced Problem Solving: Ability to debug complex physical design challenges, including structural timing violations, routing congestion etc. with minimal supervision. Education: Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field. Why join us? In this role, you will play a pivotal part in driving aggressive PPA optimizations across significant design sections, operating at the critical intersection of physical layout, RTL design, and hardware architecture. You will have the autonomy to make a substantial impact across our entire product portfolio—from highly efficient IoT cores and dense memory systems to demanding high-performance platforms. We offer a direct path for technical growth, allowing you to collaborate with world-class engineers in a supportive, fast-paced, and learning-rich environment. Additional Information: This position requires a successful background and reference checks and satisfactory proof of your right to work in: India Any offer of employment for this position is also contingent on the Company verifying that you are a authorized for access to export-controlled technology under applicable export control laws or, if you are not already authorized, our ability to successfully obtain any necessary export license(s) or other approvals. SiFive is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. Championed by leaders who chose to make a real difference, SiFive led the RISC-V revolution—creating a tremendous wave with the strength to remove economic hurdles and create opportunities for all. Now that we’ve made history, you have the opportunity to write the future. If you love to be challenged, you can join the best of the best and get rewarded for doing something that truly matters.
