About Us

We are Sennheiser, a world-leading manufacturer of audio products with over 80 years of experience, shaping the future of the audio industry with sophisticated microphones and audio solutions for studios, conference rooms, and stages. We offer you the opportunity to work in a global family company with a trusting, appreciative, and supportive team culture and to make a significant contribution to our shared progress. You can expect a modern, dynamic work environment with flexible working hours and mobile working options, an attractive collective agreement with holiday and Christmas bonuses, a 35- or 40-hour week, and a company pension plan. Further benefits include our company daycare "Ohrwürmchen", employee discounts, subsidies for healthy food in the canteen, Hansefit, Workation, and Jobrad leasing. We work in an international team on exciting projects that actively shape the future of the audio sector, and we welcome applications from all areas.

Responsibilities

• We develop architecture and design concepts for wireless transmission methods and digital signal processing algorithms based on the DECT NR+ transmission standard.
• We conduct analyses, simulations, and measurements to derive system requirements, evaluate architectural options, and identify optimization potential.
• We actively work on the DECT NR+ stack (PHY/MAC), including implementation, optimization, and troubleshooting in the embedded environment.
• We plan and manage defined functional blocks and take over time planning, technical coordination, risk management, and tracking of work packages in interdisciplinary teams.
• We conduct or moderate technical reviews, architecture workshops, design discussions, and decision-making processes with relevant internal stakeholders.
• We participate in international standardization bodies and funding projects by contributing technical requirements and actively participating in discussions and review processes.
• We provide mentoring and knowledge transfer for junior and professional engineers, strengthening team-wide expertise in wireless technologies and the DECT NR+ standard.
• We create technical documentation such as architectures, concepts, specifications, interfaces, and test concepts in close cooperation with purchasing, test/qualification, production, service, project management, and systems engineering.
• We identify innovation potential and help shape the technological roadmap, focusing on strategic reuse of architectural building blocks, guidelines, and development and integration methodologies.

Requirements

• Successfully completed studies (Master/Diplom) in telecommunications engineering, communication technology, computer science, electrical engineering, or a similar technical field, alternatively a relevant technical apprenticeship with many years of relevant professional experience in Wireless Systems, Signal Processing, or Embedded Stack Development.
• Sound knowledge and practical experience in DECT NR+ (PHY/MAC), ideally including implementation and optimization on embedded systems.
• Deep understanding of wireless transmission methods and digital signal processing, especially in the areas of Channel Coding, Time-/Frequency Synchronization, and Robustness Mechanisms.
• Experience in Embedded Stack Development with C/C++ and proficient use of Python and/or MATLAB for analysis, simulation, and prototyping.
• Experience in integrating baseband algorithms and signal processing into hardware, e.g., DSPs, FPGAs, or SoCs is advantageous.
• Experience or active participation in standardization committees and ability to handle standards, specifications, and requirements.
• Motivation to work with open-source stacks and contribute to open development models such as collaborative development and community contributions.
