What are the responsibilities and job description for the 1-Month Contract-Embedded Systems /Audio Engineer position at Rain?
RAIN Technology Inc, maker of Orva (the OR voice assistant), is seeking a hybrid engineer with expertise in embedded systems and audio engineering to assist in delivering multi-user prototypes.
The ideal candidate will have a strong background in Bluetooth device management, Raspberry Pi development, and audio signal processing, including microphone array design and/or implementation. This project involves working across two distinct prototypes to enable multi-user interaction and shared audio input/output in surgical environments.
We are excited to work with a skilled professional to deliver innovative solutions that advance the future of surgical voice assistants!
What You’ll Do:
- Advise on, design, and implement hardware/software architecture for Bluetooth management and audio signal processing.
- Partner with existing Orva software engineering and design/product teams around requirements and dependencies.
- Develop and configure a Raspberry Pi and other hardware as needed for multi-user Bluetooth routing and microphone array management.
- Integrate the solution with a device running the Orva Android app.
- Test prototypes for latency, audio quality, and user experience in simulated real-world environments.
- Address technical challenges related to wireless protocols, EMI, and audio clarity.
- Document technical designs and provide recommendations for scaling the solution.
What You’ll Bring:
- Expertise in embedded systems engineering, including Raspberry Pi development.
- Strong understanding of Bluetooth audio management, including routing and pairing multiple devices.
- Proficiency in audio signal processing, including microphone array design, beamforming, and noise reduction.
- Experience developing APIs or using lightweight communication protocols like WebSocket.
- Familiarity with Android devices and audio integration.
- Demonstrated ability to troubleshoot and resolve hardware-software integration issues.
Nice to Have:
- Experience working in healthcare or other regulated environments.
- Knowledge of electrostatic discharge (ESD) and EMI management.
- Familiarity with voice assistant technologies and ASR systems.
Project Scope & Timeline:
- Duration: ~4 weeks (open to shorter and maybe longer, depending)
- We assume this will not be a full-time position but will involve periods of heavy activity and collaboration with the RAIN team, with some breaks in workflow.
- Deliverables:
- Functional prototypes for two scenarios (multi-user Bluetooth headsets connected to a single device; far-field mic array).
- Technical documentation and implementation recommendations.
- Assistance with initial testing and debugging.
Please include examples of projects that demonstrate your expertise in Bluetooth audio management, microphone array design, and embedded systems development.
