Senior Research Engineer (f/m/d) in Berlin

HOLOPLOT develops loudspeaker systems that use 3D beamforming and wave field synthesis to control where sound is delivered with exceptional precision. At the core of every system is proprietary software that determines how each driver in an array must behave to create the intended sound field.

Our Research team advances both the software and the acoustic theory and modeling that underpin HOLOPLOT technology. As demand for innovation and product development grows, we are expanding the team to increase our capacity for research-led innovation. This role will help drive new product concepts, features, intellectual property, and the longer-term technical direction of our systems.

You’ll collaborate closely with our senior engineers while taking a leading role in HOLOPLOT’s core acoustic engine and the software and algorithmic work that shapes it. From the outset, you’ll contribute to internal tools, run and validate optimizations, and drive improvements with clear ownership, growing autonomy, and direct impact on our core systems' performance.

From week one, you’ll collaborate as a technical peer with senior engineers and lead projects that have a direct impact on our products. Over your first 6–12 months, you’ll build toward co-ownership of core components of the HOLOPLOT acoustic engine, its software and the workflows behind it, helping shape technical decisions, validation methods and future development. We’re looking for someone who works autonomously, brings scientific rigor to numerical challenges and is driven to understand not just whether a solution works, but why.

• Develop and maintain our proprietary beamforming and array optimization algorithms.

• Develop and maintain our proprietary system design and configuration software.

• Evaluate beam optimizations for products and customer projects, and validate results against simulations and measurements.

• Design and implement linear (FIR/IIR) and frequency-domain DSP methods.

• Develop non-linear DSP algorithms, such as peak/thermal limiters tailored for amplifier and driver protection.

• Plan and run acoustic measurements to verify array modeling and feed data back into models.

• Support sound system design work when projects need fine-tuning and optimization expertise.

• Improve code quality, testing and automation, including using AI-assisted development tools.

• Write clear technical reports and documentation so knowledge is shared across the team.

• Contribute ideas to patent applications and research topics as you grow into the domain.

• Degree (MSc or PhD preferred) in acoustics, audio engineering, electrical engineering, physics or a related field.

• Strong MATLAB skills for numerical simulation and optimization, with clean, maintainable code.

• Solid grounding in audio DSP

• Understanding of nonlinear signal-processing techniques and transducer modeling.

• Working knowledge of array signal processing, beamforming or sound field control.

• Understanding of general and room acoustics.

• Ability to explain technical results clearly in writing and in conversation or presentation.

• Experience with numerical optimization methods.

• Wave field synthesis, Ambisonics or other spatial audio techniques.

• Acoustic simulation tools (EASE, BEM/FEM, or similar).

• Python, version control and automated testing.

• A professional audio or live sound background, plus strong critical listening skills.

• Exposure to patent work or scientific publishing.

• Hands-on experience with audio measurement systems (e.g. Klippel, Audio Precision, REW).

At HOLOPLOT we work in a flexible hybrid setup with trust-based working hours, giving you the freedom to organise your day in a way that supports focus, deep work and balance. Pay is competitive and fair, and we offer perks and benefits such as subsidised public transport, lunch allowances, Urban Sports and a company pension scheme.

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.
