Job Summary & Responsibilities

Role summary

FEO is creating a Common EFEM (Equipment Front-End Module) platform that can be used across multiple Onto tools. We are hiring a Senior Systems Engineer to lead system-level definition and integration of the EFEM platform.

You will own system requirements and interfaces, system architecture, integration planning, and system-level validation. The work spans robotics, FOUP load ports, sensors, motion systems, environmental controls, safety, and control software.

• You often won’t have complete information. You should be able to state assumptions, identify risks, and choose tests that reduce uncertainty.
• Problems are usually harder than they look. You should expect iteration and plan for it.
• Progress is measured by results: a working integration, validated performance, reduced risk, and clear interfaces that teams can adopt.
• Clear thinking and clear communication are required. This role involves trade-offs and alignment across teams.

Responsibilities

System definition and architecture

• Define EFEM system requirements, functional specs, and interface definitions for use across multiple product families.
• Develop system architecture, module boundaries, and integration plans for:
  • robotics and wafer handling
  • FOUP load ports and related sensors
  • motion and precision positioning
  • lighting and sensing subsystems
  • airflow / environmental controls
  • safety systems
  • control software
• Set platform-level standards so the EFEM can be configured and reused without rework.

Integration leadership

• Lead integration across mechanical, electrical, software, robotics, and controls.
• Work with SMEs across robotics, motion control, safety, PCBA design, optics, and software controls to resolve interface and behavior issues.
• Define system-level metrics and acceptance criteria (throughput, placement accuracy, wafer flow reliability, environmental stability, contamination control).

Characterization and validation

• Create and execute system-level test plans for modules and integrated builds.
• Analyze data to find performance gaps (motion precision, handling reliability, vibration, thermal/environmental behavior, sensor performance).
• Drive root cause analysis and coordinate corrective actions across teams.

Standards and factory automation

• Ensure compliance with relevant SEMI standards (e.g., E84, E87, E90, E10, S2, S8) and EFEM automation requirements.
• Support interface specifications for AMHS, factory automation, and host control.
• Produce documentation needed for adoption: architecture notes, interface specs, test methods, and performance requirements.

Collaboration and technical leadership

• Work with product teams, NPI, and FEO module owners to ensure the platform fits multiple tool architectures.
• Present system behavior, trade-offs, risks, and design decisions to engineering and leadership.
• Mentor engineers on integration discipline, validation practices, and systems thinking.

Qualifications

Required

• BS or MS in Systems Engineering, Mechanical Engineering, Electrical Engineering, Robotics, Mechatronics, or related field.
• 8+ years in semiconductor capital equipment, robotics, mechatronics, precision automation, or other multidisciplinary systems.
• Experience defining system architecture, interfaces, and requirements for complex systems.
• Experience integrating robotics, precision motion, sensors, and controls into a working system.
• Familiarity with SEMI standards and factory automation interfaces used with EFEMs.
• Strong problem-solving skills using data, structured debugging, and clear written documentation.

Preferred

• Direct EFEM development experience (wafer-handling robotics, load ports, automation).
• Knowledge of contamination control, airflow management, environmental stability, and vibration mitigation.
• Experience with reliability methods (FMEA, structured root cause analysis) and platform engineering.
• Python, MATLAB, or similar tools for data analysis.
