This role is crucial for the successful integration, testing, and deployment of our cutting-edge laser-based wafer manufacturing systems. The ideal candidate will have deep hands-on experience with complex electro-mechanical and optomechanical hardware, including lasers, motion stages, and control electronics, and will be responsible for ensuring that all system components perform to specification through rigorous test and validation. This position requires a strong understanding of system-level hardware integration, and test automation, along with the ability to diagnose issues across electrical, mechanical, and optical domains. This is a hardware-focused documentation, test, and validation role - ideal for an engineer passionate about working directly with instrumentation, sensors, and high precision actuators to drive reliability and performance improvements in a fast-paced manufacturing environment. Responsibilities * Lead the hardware integration and validation of complex laser-based wafer manufacturing systems, including optical, mechanical, electrical, and precision motion subsystems. * Develop and execute detailed hardware test procedures - from subsystem acceptance tests to system-level validation - ensuring performance meets design and reliability requirements. * Perform hands-on testing, troubleshooting, and root-cause analysis across electrical, mechanical, optical and controls domains. * Work closely with technicians to ensure consistent build quality, accurate documentation, and reproducible test processes. * Design and specify test setup, instrumentation and data acquisition requirements needed to validate system functionality and performance. * Collect, analyze, and interpret test data, identifying trends, deviations, and opportunities for design or process improvements. * Contribute to the development of automation tools for data collection and test execution (LabVIEW, Python, or equivalent). * Collaborate with cross functional teams - including mechanical, electrical, optical, and software engineers to resolve integration and performance issues. * Contribute to design and readiness reviews, providing feedback focused on hardware testability, manufacturability, and serviceability. ## 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) - [Dirty Tests And How To Clean Them](https://www.wearedevelopers.com/videos/515-dirty-tests-and-how-to-clean-them) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [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) - [Stop Guessing, Start Measuring: Evaluating RAG Systems with Synthetic Test Data](https://www.wearedevelopers.com/videos/1982-stop-guessing-start-measuring-evaluating-rag-systems-with-synthetic-test-data) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
