The ideal candidate is We are seeking an experienced and proactive Hardware Validation Engineer with a strong background in mechanical engineering to be the driving force behind product reliability for our active loudspeaker systems. The ideal candidate: Has a strong background in mechanical engineering. Is highly collaborative and hands-on. Is comfortable acting as the primary technical bridge between an external mechanical engineering lead and mechanical engineering team (US-based) and an internal multi-disciplinary development team (electrical, acoustics, software) in Europe. Is willing and able to travel up to 20% domestically and internationally. Has the ability to travel to the US. Main objectives of the role Lead the validation and testing strategy for all mechanical components and full product assemblies. Have a direct impact on product quality from the earliest prototype stages through to mass production. Function as the main communication conduit between the external US-based mechanical engineering team and the Berlin-based development teams. Your role and responsibilities Validation strategy and execution: Design, develop, and execute comprehensive validation and reliability test plans for mechanical components and complete active loudspeaker products. Perform hands-on testing on prototypes and ensure product durability and robustness by specifying and arranging dedicated test procedures (e.g., environmental, shock/vibration, life-cycle). Prototyping lead on mechanical engineering: Take the lead during all prototyping phases in Berlin, ensuring an intense focus on early mechanical validation and failure prevention through DFMEA and risk analyses. Drive the definition and execution of mechanical test procedures for prototypes built on-site. Design for excellence: Actively participate in design reviews, critically applying DFM (Design for Manufacturability) and DFA (Design for Assembly) principles. Provide practical, engineering-focused feedback to the design teams to optimize mechanical parts for high-volume, quality production. Technical bridging and collaboration: Function as the main communication conduit between the external US-based mechanical engineering team and the Berlin-based development teams. What you need to succeed in this role Education and experience: Bachelor's degree in mechanical engineering or a related technical discipline. Proven professional experience in a hardware validation, reliability, or quality engineering role focused on physical products with strong electro-mechanical integration. Testing and prototyping expertise: Demonstrable hands-on experience creating, managing and performing detailed hardware validation protocols. Strong experience with building fast prototypes, validating concepts and designs as early as possible. Manufacturing and design acumen: Strong working knowledge of DFM/DFA methodologies and how mechanical design impacts manufacturing quality and yield. Experience with manufacturing processes such as extrusion, injection molding, die casting and additive manufacturing. CAD software experience for mechanical design reviews, tolerance analysis, and support of manufacturing/assembly teams. Experience with PTC Onshape is considered a strong plus.

You’ll join an international, open-minded team across software, hardware, product and research, in an environment with plenty of autonomy and ownership. You’ll work on cutting-edge audio technology, turn complex requirements into working solutions and contribute to global projects, with support for your growth through individual development plans, mentoring and coaching. About us We are a pro audio company from Berlin, Germany. Since early 2011, we have been working on radically transforming audio technology, by re-thinking the underlying physics of sound reproduction. We wondered: What if sound could truly be controlled the way we can control light? What if we could create soundscapes that feel more real than reality? What if every seat in a venue could be made the best seat? Our solution is science-based, software-driven, and hardware-enabled: the HOLOPLOT Matrix Array. The sound system for a new era, a powerful tool that brings previously inaccessible capabilities to the world of audio. We believe when people experience better sound, they will enjoy more meaningful moments and create richer memories, leading to more fulfilling lives. At HOLOPLOT, it is our mission to redefine what is possible - enabling unparalleled and breathtaking experiences. A revolution in sound. Be part of it.
