Job Type: Contract-to-Hire

Job Summary

We are seeking an experienced Senior Signal Integrity Engineer High-Speed Hardware to support the development of next-generation enterprise storage platforms.

The ideal candidate will have strong hands-on experience in high-speed signal integrity simulation, 3D electromagnetic extraction, PCB channel analysis, and laboratory measurements. Deep experience with Simbeor and PCIe is highly desirable for this role.

Key Responsibilities

• Own signal integrity analysis for high-speed hardware from architecture through production.
• Drive board-level SI decisions involving PCB materials, stackups, via structures, channel optimization, and signal-loss tradeoffs.
• Perform SI simulations including:
  • Insertion Loss (IL)
  • Return Loss (RL)
  • Crosstalk
  • TDR/impedance analysis
  • Eye diagrams
  • Jitter and margin analysis
• Lead TDR and S-parameter measurements, including measurement setup, calibration, and de-embedding.
• Perform 3D electromagnetic extraction and simulation for vias, connectors, and complex high-speed channel structures.
• Correlate simulation results with laboratory measurements and refine models and design assumptions.
• Use and customize IBIS and IBIS-AMI models for PCIe and other high-speed interfaces.
• Support hardware debug activities where signal integrity is a contributing factor.
• Perform Power Integrity (PI) simulations and analysis.
• Collaborate with PCB design, system, firmware, mechanical, and test engineering teams.
• Evaluate system-level tradeoffs involving signal integrity, performance, mechanical, thermal, and power requirements.
• Develop SI design guidelines, methodologies, and best practices.
• Provide technical leadership and mentorship to junior engineers.

Required Qualifications

• 5+ years of experience in Signal Integrity engineering for high-speed systems.
• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field. Master's degree is a plus.
• Strong SI simulation experience with PCIe and high-speed channel analysis.
• Hands-on experience with TDR and S-parameter measurements.
• Experience with measurement calibration and de-embedding.
• Strong understanding of PCB design from a signal integrity perspective, including:
  • PCB materials
  • Stackup design
  • Via structures
  • Routing
  • Channel optimization
• Deep hands-on experience with Simbeor for 3D electromagnetic extraction and simulation.
• Experience with eye diagrams, jitter, signal margins, insertion loss, return loss, and crosstalk.
• Experience using IBIS / IBIS-AMI models.
• Understanding of Power Integrity and SI/PI interactions.
• Ability to evaluate system-level design tradeoffs.
• Strong analytical and problem-solving skills.
• Excellent communication and cross-functional collaboration skills.
• Ability to work independently in a fast-paced technical environment.

Preferred Qualifications

• Experience with SSD, NVMe, enterprise storage, or data-center hardware.
• Experience with PCIe Gen4/Gen5.
• Experience with NAND or DDR interfaces.
• Experience with VNA-based measurements.
• Experience with additional SI/EM tools such as HFSS, CST, ADS, or Cadence Sigrity.
• Experience developing SI design guidelines and methodologies.
• Experience leading cross-functional hardware development activities.
