About the Role We are seeking a Senior Physical Design Engineer to join our high-performance design team working on next-generation transceiver IPs targeting the TSMC 3nm and advanced technology nodes ### Key Responsibilities Perform block-level and top-level physical implementation including floorplanning, placement, clock tree synthesis (CTS), routing, and physical verification for high-speed designs in advanced technology nodes. Collaborate with RTL and STA teams to ensure clean handoffs and support timing, area, and power convergence. Apply advanced physical design techniques to support multiple voltage and frequency domains, hierarchical design, and physical-aware synthesis. ### Work on key physical design areas including EM/IR analysis and power grid optimization Congestion analysis and mitigation Clock skew optimization and clock quality improvement RC extraction-aware placement and routing Integrate IPs and top-level blocks with attention to physical interfaces, constraints, and timing alignment. Support floorplan development and chip partitioning for high-speed transceiver designs. Perform ECO implementation and assist with tapeout signoff activities. Ensure DRC, LVS, ANT, CELL, and ERC clean databases using industry-standard physical verification tools. Use industry-standard tools such as ICC2, Innovus, Voltus, RedHawk, and Calibre for implementation and signoff. Develop and maintain automation scripts in Tcl, Python, or Perl to improve physical design flows and productivity. ### Required Qualifications Bachelor’s or Master’s degree in Electrical Engineering, Electronics Engineering, or a related field. 5+ years of experience in physical design, preferably with advanced technology nodes. Strong experience with: Floorplanning, placement, CTS, routing, and IR drop mitigation Signoff checks such as DRC, LVS, ANT, and ERC, along with debugging Timing closure support in collaboration with STA teams Hands-on use of tools such as Synopsys ICC2, Cadence Innovus, Calibre, and Voltus Experience integrating high-speed IPs such as SerDes or PHYs into SoC or chiplet-based environments. Experience working on high-frequency datapath and DSP-related designs. Solid scripting skills for automation and productivity enhancement. Good problem-solving skills and the ability to work effectively in cross-functional teams. We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities. ## At a glance - Posted by the employer: Aug 4, 2026 - First seen by OpenNash: Oct 11, 2026 - Last checked: Oct 18, 2026 - Listed for: 75 days - Location: Singapore City[Apply on Astera Labs’s careers site →](https://job-boards.greenhouse.io/asteralabs/jobs/4720222005) ## More jobs at Astera Labs ### [Principal Physical Design Engineer](https://jobs.opennash.com/companies/astera-labs/jobs/5ae3212357921794e632/) Singapore City ### [Teach Lead Physical Design Engineer](https://jobs.opennash.com/companies/astera-labs/jobs/8048facae27e4884328e/) Singapore City ### [Senior Analog Mixed-Signal IC Layout Engineer](https://jobs.opennash.com/companies/astera-labs/jobs/221d9e3fe5624daf8663/) Singapore City ### [Tech Lead Analog Mixed-Signal IC Layout Engineer](https://jobs.opennash.com/companies/astera-labs/jobs/0e396d4d7516da1c993a/) Singapore City ### [Analog Mixed Signal Design Engineer](https://jobs.opennash.com/companies/astera-labs/jobs/b79c33909c027beb9e25/) Singapore ## Similar jobs at other companies ### [CPU Physical Design Engineer](https://jobs.opennash.com/companies/qualcomm/jobs/27bd54e804c3da2d6519/) Qualcomm · Bangalore, India ### [NPU Physical Design Engineer](https://jobs.opennash.com/companies/qualcomm/jobs/916f75702172388c2ee7/) Qualcomm · Bangalore, India ### [Physical Design Engineer II](https://jobs.opennash.com/companies/microsoft/jobs/2d7f9c2e826bc117df12/) Microsoft · India, Karnataka, Bangalore ### [Silicon Physical Design CAD Engineer](https://jobs.opennash.com/companies/microsoft/jobs/d047141045a6e2b56e7a/) Microsoft · India, Karnataka, Bangalore ### [Senior Staff Engineer Physical Design and Methodology (f/m/div)](https://jobs.opennash.com/companies/infineon-technologies/jobs/46bbe226ff31021fb81f/) Infineon Technologies · Munich OpenNash lists jobs from employers’ own careers sites and does not handle applications.
