Senior Lead Engineer, Electrical Design - Signal Integrity

About the Role

The Senior Lead Engineer, Electrical Design develops new electrical systems and circuits for various applications. This role involves researching system ideas, creating schematics and system specifications, testing, simulating, validating, and qualifying systems, and providing support throughout manufacturing. You will work in cross-functional teams with designers, customers, manufacturing engineering, and project leadership to ensure robust and high-quality product development. Feedback from reviews in areas such as manufacturing, test, supply chain, reliability, industrial design, and simulations will be used to enhance designs.

Responsibilities

• Lead the design, development, and implementation of technical solutions in multiple domains.
• Participate in project planning and scheduling.
• Provide technical leadership and direction to a team of engineers.
• Serve as a recognized expert (go-to person) in one or more technical areas.
• Review, interpret, and negotiate customer requirements/specifications; provide customer feedback.
• Lead the deployment of strategic programs and coordinate site-wide deployment efforts.
• Proactively promote industry best practices.
• Manage relationships with key vendors/partners.
• Design, modify, and implement systems that meet customer and Celestica needs (e.g., creation of schematics, bills of material, diagrams, drawings).
• Test, simulate, and measure (including troubleshooting) the performance of systems.
• Keep up to date with relevant industry knowledge and regulations.
• Solve complex problems.
• Liaise with suppliers, customers, contractors, and other internal teams.
• Analyze and interpret data and information.
• Recommend modifications for systems.
• Create reports and documentation.

Requirements

• Experience in PCB design fundamentals, including single-ended and differential signals.
• Proficient in managing signal integrity challenges such as signal loss, impedance control, and crosstalk (near-end and far-end).
• Experience with single-ended and differential signaling up to 50Gbps.
• Skilled in working with component models (Touchstone files) and cascading them to create comprehensive system models for simulation.
• Experienced in simulating digital interfaces (FPGA to DRAM, SERDES) and analog paths (PCB, connector, cable from signal driver to DUT).
• Proficient with 2D and 3D simulation tools (e.g., ADS, ANSYS HFSS, Sigrity).
• Capable of electrical length calculations for signal matching.
• Familiar with interpreting signals in both frequency (S-parameter) and time domains to assess suitability for applications.
• Proficient in generating and interpreting data-eye diagrams up to 50Gbps for NRZ and PAM4.
• Proficient with Allegro or similar layout tools and schematics.
• Expertise in PCB stack-up design, considering fabrication limitations and cost trade-offs.
• Experience with high-frequency board materials.
• Significant experience in measuring signal performance in the lab, including TDR and VNA measurements.
• Able to develop test fixtures, from custom test boards to ad hoc probing solutions for troubleshooting.
• Experienced in balancing cost vs. performance tradeoffs in signal path design.
• Experience with flex circuit design for high-speed signaling.

Qualifications

Typically requires 4 to 6 years of experience in a similar role or industry. A bachelor's degree or an equivalent combination of education and experience is required. Educational requirements may vary by geography.

Physical Demands

• Duties are performed in a normal office environment.
• May require extended periods of sitting and sustained visual concentration on a computer monitor or detailed data.
• Repetitive manual movements (e.g., data entry, using a computer mouse, using a calculator) are frequently required.
• Occasional travel may be required.
