Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Performance Engineer - **Company:** Focused - **Location:** Darmstadt, Germany (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Computer-Aided Design, Systems Engineering, Configuration Management, Software Documentation, Python (Programming Language), MATLAB, Monte Carlo Methods, Zemax, Ansys - **Published:** May 13, 2026 - **Apply:** https://de.indeed.com/viewjob?jk=3eea3f4f032846d6 ## About the Role Do you have experience in Systems engineering?, * 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. ## Description * 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. ## Related Videos - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Cloud Vendor Lock-In - Is it just a new version of the Database Abstraction Layers?](https://www.wearedevelopers.com/videos/1185-cloud-vendor-lock-in-is-it-just-a-new-version-of-the-database-abstraction-layers) - [Strange New Worlds: shaping the future of the digital age](https://www.wearedevelopers.com/videos/677-strange-new-worlds-shaping-the-future-of-the-digital-age) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) - [Colorful quantum randomness](https://www.wearedevelopers.com/videos/100257-colorful-quantum-randomness) ## Related Articles - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023) - [Software Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/194-software-developer-salary-in-germany-2023) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
