Performance Engineer

Responsibilities

• Own System Performance Across Product LifeCycle:
• Define and maintain system level performance driven baselines (including neutron and x-ray output power, reproducibility, beam pointing and positioning, tolerances, stability, sensitivities).
• Collaborate closely with customers and suppliers to derive future product requirements and translate them into system specifications.
• Assess System Stability and Sensitivities:
• Develop and apply system-level models to analyze sensitivities to mechanical tolerances, thermal effects, and environmental and seismic influences.
• Use Statistical methods (e.g. MonteCarlo) to quantify performance margins
• Feed derived constraints and tradeoffs back into performance, layout, and integration baselines.
• Maintain the necessary performance budgets on system level and break down requirements into component specifications.
• Lead Performance Driven Requirement Engineering in System Engineering:
• Translate performance-driven requirements into specifications for realizable, verifiable and serializable system architectures.
• Drive milestones and design reviews focused on performance maturity.
• Contribute to engineering frameworks, documentation standards, and cross-functional processes.
• Drive Performance Verification and Validation:
• Define performance verification and validation strategy.
• Establish traceability from system performance objectives through subsystem requirements to verification plans and test results.
• Collaborate Across Disciplines:
• Provide integration leadership by ensuring alignment across disciplines (mechanical, layout, laser, vacuum, controls, safety, operations) and ensure consistency of empirical integration data with functional and physical baselines from a performance perspective.
• Bridge Research to Industrialization:
• Support the transfer of experimental concepts into stable, reliable and scalable systems.
• Govern configuration control and evaluate change impacts on performance-related system aspects.
• Support the implementation of Systems Engineering and Performance methodologies across the organization.
• Drive clear and transparent decision-making.

Requirements

• 5+ years developing large, integrated, complex interdisciplinary systems within complex environments (e.g., high-power lasers, semiconductor, accelerator, nuclear, medical devices, or advanced manufacturing).
• Advanced Degree in Physics or Mechanical Engineering, related or equivalent education and experience.
• Solid expertise in system level modeling & analysis (e.g. MATLAB, python), including tolerance, sensitivity and stability analysis using statistical methods (e.g. Monte-Carlo).
• Experience with CAD literacy, FEM-tools (e.g. ANSYS) and optical simulation (e.g. Zemax) is highly beneficial for interpreting layout-driven performance impacts.
• Experience with system performance integration and scalability of large engineering systems is highly beneficial.
• Fluency in English required; German proficiency is a strong plus.
