Job Title: Senior ASIC Timing Signoff and Front-End Implementation Engineer

At SpaceX, we're pushing the boundaries of space technology and innovation. We're seeking a highly skilled Senior ASIC Timing Signoff and Front-End Implementation Engineer to join our team.

About the Role:

We're looking for a talented engineer to develop cutting-edge next-generation ASICs for deployment in space and ground infrastructures around the globe. As a Senior ASIC Timing Signoff and Front-End Implementation Engineer, you will be responsible for:

  • Full chip and block level timing signoff and convergence through timing ecos on post routed database for various timing signoff checks
  • Full chip and block level front-end implementation from timing constraints development, synthesis, formal verification, power intent generation & validation
  • Develop block and full chip level timing constraints for test modes
  • Timing closure ownership throughout the entire project cycle (RTL, synthesis, and physical implementation)
  • Analysis of clock domain crossing paths at block and full chip level
  • Work with mixed signal IP/PLL/SerDes/PHY teams to drive integration, timing, logical equivalence checking and analysis of various IPs into RTL
  • Develop/modify/run RTL logic synthesis, formal verification, power intent verification and post synthesis timing validation flows
  • Execute low power design and physical synthesis, deploying knowledge of unified power format and power intent verification
  • Implement Functional ECOs for complex blocks
  • Deploy and enhance methodology and flows related to timing constraint generation and verification and timing closure
  • Work closely with chip architecture, design verification, physical design, DFT, and power teams to achieve tapeout success on designs - generally bridging the RTL and place and route
  • Work with multi-disciplinary groups to make sure RTL/Netlists are on schedule and delivered with the highest quality by incorporating automated checks at every stage of the design process
Requirements:
  • Bachelor's degree in electrical engineering, computer engineering or computer science
  • 5+ years of experience working as a synthesis and/or front-end STA engineer
Preferred Skills and Experience:
  • Experience in ASIC multimode constraint generation, constraint partitioning and timing closure in advanced nodes
  • Experience with test modes, mode merging to optimize physical design implementation and STA Signoff
  • Experience with power intent and upf development for block and soc top
  • Familiar with formal verification and implementing functional ecos
  • Knowledge of deep sub-micron FinFET technology nodes (7nm and below) timing challenges, multi-corner and multimode timing closure, process variations (AOCV, POCV based STA), voltage drop aware STA, and clock reconvergence pessimism removal
  • Hands-on experience in industry standard physical synthesis and STA tools (Synopsys DC, Primetime or equivalent)
  • Experience with clock domain crossings, DFT/Scan/MBIST/LBIST and understanding of their impact on synthesis, physical design and timing closure
  • Deep understanding of ASIC design flow, top-down and bottom-up design methodologies
  • Knowledge of low-power methodologies and leakage/dynamic power optimization flows and techniques
  • Familiar with implementation or integration of design blocks using Verilog/SystemVerilog
  • Experience with high reliability design and implementations
  • Excellent scripting skills (csh/bash, Perl, Python, TCL, Makefile etc.)
Additional Requirements:
  • Must be willing to travel when needed (typically)
  • Willing to work extended hours and weekends to meet critical deadlines, as needed
Compensation and Benefits:

Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock, stock options, or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan.

You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks.

You may also accrue 3 weeks of paid vacation & will be eligible for 10 or more paid holidays per year.

Exempt employees are eligible for 5 days of sick leave per year.
