Senior Physical Design Engineer

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E‑Space is bridging Earth and space to enable hyper‑scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly‑advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space‑based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

• Lead physical design implementation from floor planning through GDSII sign‑off for complex SoC blocks and full‑chip designs
• Perform floor planning, power planning, placement, clock tree synthesis (CTS), and routing
• Drive physical design closure meeting PPA (Power, Performance, Area) targets across all design corners
• Collaborate with the STA team to analyze and resolve timing violations through ECO‑driven optimization
• Conduct and resolve physical verification (DRC, LVS, ERC) issues in partnership with the signoff team
• Develop and maintain physical design scripts, flows, and automation in Tcl/Python
• Work with foundry process design kits (PDKs) and ensure design rule compliance on advanced nodes
• Support integration of hard macros, memory compilers, and analog IP into top‑level designs
• Analyze and optimize signal integrity, including crosstalk and noise effects
• Contribute to physical design methodology development and mentor junior engineers

• Minimum 8+ years of experience in physical design of complex digital ASICs or So Cs
• Deep expertise in Cadence Innovus, with broad familiarity with other P&R tools such as Synopsys ICC2
• Strong experience in floor planning, power planning, placement, CTS, and routing for multi‑million gate designs
• Deep knowledge of timing‑driven physical design and working with STA engineers for timing closure
• Experience with physical verification tools (Mentor Calibre, Synopsys ICV) and DRC/LVS debug
• Proficiency in scripting (Tcl, Python) for flow development and automation
• Solid understanding of low‑power design techniques (clock gating, power domains, UPF/CPF)
• Experience with advanced process nodes and associated PDK constraints
• Strong problem‑solving skills and attention to detail in a deadline‑driven environment

• Experience with 7nm or sub‑7nm process nodes
• Exposure to custom digital or mixed‑signal IC physical design
• Familiarity with signal integrity analysis tools and methodology
• Experience with hierarchical physical design flows for very large So Cs
• Background in satellite, 5G, or IoT chip design

The target base pay for this position is $120,000 – $220,000 annually. The total compensation packaged will be determined by various factors such as your relevant job‑related knowledge, skills, and experience.

This is a full‑time, exempt position, based out of our Saratoga office.

We are redefining how satellites are designed, manufactured and used. If you have experience in LEO satellite component development, design and in‑orbit activities, we will be immediately wow‑ed.
