Job summary

REOLINK TECHNOLOGY PTE. LTD. in Singapore is seeking an Audio Algorithm Engineer (Master/PhD) to develop streaming, multilingual speech recognition and audio understanding on camera devices. You will optimize models for low latency, integrate with firmware, and push end-to-end audio pipelines from data prep to deployment.

You will work with Whisper/CLAP-like encoders, apply quantisation and distillation, and collaborate with firmware engineers to ship real-time audio AI features on hardware.

Qualifications

• Master's Degree or PhD in Computer Science, Electrical Engineering, Signal Processing, Acoustics, AI or related field, focused on speech or audio.
• Hands-on experience training and evaluating deep learning models for audio in signal-level tasks and understanding tasks.
• Solid foundation in audio signal processing: STFT, filterbank, mel features, pitch/harmonics, room acoustics and reverberation, SNR and level.
• Familiar with audio front-end processing (noise suppression, echo cancellation, dereverberation, gain control, VAD).
• Able to design and train small, streaming models under compute/memory/latency budgets; familiar with quantisation, pruning and distillation.

Responsibilities

• Speech Recognition: Develop streaming multilingual speech recognition and keyword spotting for far-field audio from a single camera microphone.
• Voice Interaction: Develop VAD, end-of-turn detection, turn-taking and barge-in; compare cascades with full-duplex speech models.
• Speech Enhancement: Develop noise suppression, echo cancellation, dereverberation and target-speaker extraction for one mic.
• Sound Events and Audio Understanding: Develop sound event detection, audio classification and captioning.
• Model Training and Evaluation: Run experiments end-to-end, from data prep to training, fine-tuning and ablations; build evaluation harnesses.
