Sr. Field Service Engineer

Direct Field Service enables customer success through on-site installation, repair, preventive maintenance, engineering change upgrades, escalation support, and equipment lifecycle service for Lam equipment. The organization is responsible for safe, high-quality, scalable execution that improves installed base performance, productivity, customer trust, and business results.

As an FSE4 or FSE5 at Lam, you will act as Engineer in Charge (EIC), senior technical owner, and technical counterpart to service management. These roles are senior technical leadership positions, not primarily shift-coverage or transactional repair roles. You will own complex troubleshooting, structured problem solving, technical recovery plans, installation and machine-performance execution, and customer-facing technical communication. You will convert ambiguous problems into defensible models, executable game plans, safe work plans, clear decisions, and measurable results, maintaining technical continuity until success criteria are met or ownership is formally transferred.

• Serve as Engineer in Charge (EIC) or senior technical owner for assigned product lines, tool sets, installations, escalations, upgrades, conversions, or recovery projects, with clear accountability for technical outcomes and customer/company commitments.

  Establish a single executable technical plan with clear problem definition, success criteria, decision points, owners, timing, required resources, risk controls, and escalation thresholds.

  Lead complex, ambiguous, intermittent, chronic, or high-impact troubleshooting from containment through hypothesis development, model creation, testing, learning, verification, permanent resolution, and recurrence prevention.

  Create and maintain Model Based Problem Solving (MBPS) artifacts, including accurate problem statements, system models, fault hypotheses, test matrices, decision trees, evidence, conclusions, and next actions.

  Develop executable game plans that define work sequence, resources, parts, procedures, data capture, hold points, recovery options, and success criteria.

  Create, review, and lead Pre-Task Plans (PTP), risk assessments, procedure reviews, safe-state verification, and stop-work decision points for high-risk, complex, or non-standard work.

  Lead technical execution for installations, evaluations, upgrades, conversions, qualifications, productivity programs, and sustaining recovery efforts, including OIM/microschedule content, dependencies, risks, hold points, and recovery paths.

Minimum Qualifications:

• FSE4: Bachelor's degree in Electronics, Engineering, or a related technical field with 7+ years of relevant semiconductor equipment service, installation, escalation, or product-support experience; or an equivalent combination of education and experience.

  FSE5: Bachelor's degree in Electronics, Engineering, or a related technical field with 10+ years of relevant semiconductor equipment experience, or an equivalent combination of education and experience, plus demonstrated technical-manager-level leadership and product-line impact.

  Demonstrated success as an EIC, technical lead, escalation owner, installation lead, project owner, or equivalent leader for complex semiconductor capital equipment.

  Demonstrated ability to create structured problem-solving models, test plans, technical recovery strategies, risk assessments, customer-ready reports, and defensible troubleshooting models using schematics, logs, tool data, procedures, parts history, process symptoms, and failure signatures.

  Ability to influence cross-functional teams and communicate effectively with technicians, engineers, managers, customers, and executives.

  Willing to work in a clean room environment while wearing personal protective safety equipment, or cleanroom suit.

  Frequently position oneself (e.g., bend, stoop, reach, walk, sit, twist, squat, kneel, climb, stand) to perform job tasks for extended periods.

  Willing to travel frequently, domestically and internationally, based on customer needs, flexibility to work a variety shifts including compressed and alternative workweeks including overtime and on-call if needed.

We believe it is important for every person to feel valued, included, and empowered to achieve their full potential. By bringing unique individuals and viewpoints together, we achieve extraordinary results.
