2. A technical interview (60 mins).

3. Final feedback received within a couple of days after the interview.

Join us on this exciting journey where you'll have the opportunity to work on groundbreaking projects and shape the future of the IoT industry. Embrace the challenge, unleash your creativity, and be part of a team that is passionate about making a real impact in the world of technology 🦾

Required Technical Stack Experience:
- Expert level in Unity development, especially for VR applications on Android (Meta Quest devices).
- Expert level in C# and implementing efficient data handling.
- Expertise in designing, developing, and maintaining API and SDK for others to use.
- Strong knowledge of efficient memory management and data processing pipelines.
- Deep understanding of platform limitations, especially on VR devices.
- Knowledge of integrating with cloud streaming and storage of real-time sensor data.

Expected Knowledge in the DSP Domain:
- Experience with real-time data streaming and processing, ideally for biometric or sensor-based data.
- Experience in implementing and optimizing DSP algorithms, particularly real-time signal processing.
- Understanding of EEG and PPG signal characteristics and quality assessment.

Nice-to-Have Technical Stack Experience
- Java knowledge, particularly in Android development, for working on communication protocols.
- Familiarity with BrainFlow or similar libraries in sensor and DSP data handling.
- Experience with hardware integration in Unity (though no firmware work is required).
-Experience in Noise Reduction and Signal Filtering Techniques for real-time biometric data.
- Experience in Latency Optimization and Predictive Algorithms for Signal Processing. Familiarity with algorithms to predict signal fluctuations or compensate for delays (such as predictive coding) would enhance the VR experience.
- Knowledge of Data Security and Privacy Practices required while working with sensitive biometric data, and familiarity with data security protocols and practices.
