Own physical implementation through sign-off for advanced-node ASIC projects.About NativechipsNativechips (NC) is a US-based company with teams in the US and Cairo, building an AI-augmentedplatform for chip design. We work across proprietary and open-source EDA stacks, applying AI/ML tomake chip design faster and more accessible. We deliver platforms to IDMs and offer self-serve PaaS to design teams worldwide. We're a small, senior team — every hire shapes the product and the company.About the roleWe're hiring a Senior PnR Engineer to own physical implementation on customer projects, including22nm work. You'll handle synthesis through timing sign-off using proprietary tools (Synopsys, Cadence, Siemens), partner with foundries on tape-out submission, and serve as a senior IC on our small core silicon team.What you'll doOwn synthesis, floorplan, placement, and routing for customer ASIC projectsDrive timing closure across all corners and modesRun physical verification (DRC, LVS, ERC) and drive sign-offPartner with foundry teams for tape-out submissionCoordinate with verification on the design-to-physical handoffWhat we need from you6+ years PnR experience with at least one sub-65nm tape-out shippedSynopsys ICC2 / Fusion Compiler OR Cadence Innovus production expertiseTiming sign-off (Synopsys PrimeTime or Cadence Tempus) fluencyPhysical verification sign-off experience with Siemens Calibre (industry standard) or Synopsys IC Validator or Cadence PegasusBSc/MSc in Electrical Engineering or related fieldBonus points for22nm or smaller node physical design experiencePower and IR closure tools — Ansys RedHawk-SC, Cadence Voltus, or Synopsys PrimePowerOpenROAD or other OSS PnR familiarityMulti-patterning sign-off experience (DPT/TPT)Experience leading PnR sub-teams or methodologyWhy NativechipsDirect impact on product direction and engineering culture from day oneWork alongside a senior, founder-led team with deep semiconductor industry experienceCairo-based engineering team with US headquarters; remote-friendly working modelCompetitive compensation with meaningful stock options for early hiresWork on technically substantial problems — not maintenance workLocation: Cairo-based, remote-friendly.
