About The Role

We are developing the next generation of intelligent systems that combine embedded sensing, AI at the edge, predictive maintenance, and natural language interfaces. If you're excited about deploying ML pipelines in real-world hardware, turning unstructured prompts into actions or queries, and working across the spectrum of edge devices, cloud infrastructure, and AI modeling - we want to work with you.

As a Senior AI Engineer, You Will

i. Drive research initiatives and proof-of-concepts that push the state of the art in generative AI and large-scale machine learning for home-automation projects.

ii. Develop AI agents that can interpret, plan, and act autonomously in response to multi-modal inputs

iii. Design and implement high-throughput, low-latency AI/ML pipelines and to operate at global scale.

iv. Work on prompt engineering and iteratively develop LLM-based solutions tailored to custom use cases like text-to-SQL, text-to-command, and context-aware queries.

v. Develop and optimize AI models for deployment on embedded hardware.

vi. Prototype novel generative AI solutions, integrate advancements into production, and collaborate with research partners.

vii. Integrate real-time streaming data (video/audio/sensor) into analytics pipelines and AI workflows.

viii. Develop MLOps pipelines : versioning, continuous training, deployment, and monitoring of models.

ix. Collaborate on cloud infrastructure (AWS) for scalable backend and edge-cloud sync.

Required Skills

i. Solid foundation and expertise in developing and deploying statistical ML models

ii. Experience with ML frameworks like Scikit-learn, PyTorch, TensorFlow,OpenCV etc.

iii. Hands-on experience with real-life signal/data processing (audio, sensor data etc.) is a must

iv. Understanding of MLOps tools and lifecycle (e.g., MLflow, DVC, monitoring tools)

v. Strong proficiency in Python and/or C/C++

vi. Experience in building multi-modal AI systems (combining text, audio, sensor, vision inputs)

vii. Familiarity with voice activity detection (VAD), wake-word detection, and speech-to-command pipelines

viii. Hands-on experience with time-series analysis and forecasting models for predictive maintenance

ix. Experience with GenAI, prompt engineering and LLMs along with APIs
