Department Overview

Motorola Solutions stands as a global titan in integrated physical security and public safety, leveraging a comprehensive ecosystem of mission-critical tech.
The Oslo RD team is a lean, dynamic group responsible for expanding our hardware portfolio for enterprise security. We are a team with a start-up mentality backed with the strength of a global, trusted company. One of our primary tracks right now is significantly enhancing our audio product portfolio. Working in our team means you won't just be executing tasks—you will have the unique opportunity to lead the technological direction for the next generation of our security products.

Job Description

We are seeking an experienced Acoustic Engineer to lead the audio hardware design and tuning for our security product line, with a strong focus on two-way "talk-down" devices. In this role, you will own the end-to-end acoustic performance of our devices, from defining initial system requirements and selecting components to final DSP tuning and mass production testing. You will work cross-functionally with Electrical Engineering (EE), Mechanical Engineering (ME), and external Joint Design Manufacturing (JDM) partners to ensure our security devices deliver loud, clear, and reliable audio in challenging environments.

Key Responsibilities:

Acoustic Architecture & Design

• Define Requirements: Establish and document clear acoustic performance requirements and target specifications for new security products and talk-down devices.

• Component Sourcing: Evaluate, select, and qualify core audio transducers and electronics, including loudspeakers, microphones, and audio amplifiers.

• Hardware Integration: Lead the physical acoustic design to meet performance targets. This includes calculating and designing optimal speaker enclosures (back volumes), determining strategic microphone placement for clear voice capture, and designing acoustic ports and protective meshes (waterproofing/dustproofing).

• Cross-Functional Collaboration: Partner closely with Electrical Engineering (EE) teams to design and review audio circuit schematics, ensuring clean signal paths and optimal power delivery to amplifiers.

• JDM Management: Oversee and guide both internal engineering teams and external JDM partners, ensuring all mechanical and acoustic designs strictly adhere to required performance standards.

Audio Tuning & Signal Processing

• Playback Optimization: Implement equalization (EQ), dynamic range compression (DRC), and limiting to maximize loudspeaker loudness and vocal clarity while preventing transducer distortion or damage.

Testing, Validation & Production

• R&D Validation: Define, develop, and oversee R&D acoustic testing methodologies. Guide internal labs and JDM partners through the validation process to ensure prototypes meet design specifications. Identify and mitigate acoustic challenges such as rattling and leakage.

• Mass Production Testing: Establish robust acoustic test methods and pass/fail criteria for the manufacturing floor to guarantee consistent audio quality and yield in mass production.

Basic Requirements

• Bachelor’s or Master’s degree in Acoustics, Electrical Engineering, Mechanical Engineering, Physics, or a related field.
• 5-10 years of experience in the field of acoustics or audio engineering.
• Proven experience in debugging acoustic-mechanical issues such as rattling and sealing.
• Hands-on experience with audio measurement equipment and software.
• Previous experience managing or collaborating with overseas ODM/JDM partners is a plus.

This position offers significant room for professional growth. You will have dedicated opportunities to expand your skill set and integrate advanced audio algorithms and AI edge computing into our next-generation security systems, depending on your interest, capability and capacity. A few examples:

• Advanced Voice Processing: Expand into developing and tuning Acoustic Echo Cancellation (AEC) for seamless two-way communication, alongside microphone beamforming and advanced noise reduction to isolate human voices in noisy outdoor environments.
• Sound Localization: Research and implement spatial audio techniques to determine the direction of a sound source, allowing security cameras to automatically pan toward threats.
• AI Edge Audio & Machine Learning: Exploration and integration of AI-driven acoustic features, including:
  • Sound Classification: Training models to recognize specific security events (e.g., glass breaking, sirens, aggressive shouting).
  • Keyword Detection: Implementing CNN-based or lightweight LLM-driven trigger word recognition at the edge.
