Edge AI Engineer

Job description

Sigma Connectivity'sEdge AI initiatives span multiple domains-computer vision, audio intelligence, sensor fusion, and embedded ML-delivering low-latency, privacy-preserving intelligence directly on devices across diverse hardware platforms. Projects routinely involve developing and optimizing ML models for tasks such as gesture recognition, defect detection, object tracking, and contextual human-machine interaction, deployed on edge hardware including Qualcomm, NVIDIA, NXP, and other MCU-class systems. Work includes quantization, DSP/NPU acceleration, real-time analytics, and combined cloud-edge pipelines that enhance precision while keeping compute close to the data source.

We are looking for a skilled ML Engineer to join our growing team and contribute to the development of advanced edge AI solutions.

Your work will include -

Model Design and Deployment: On-Device

• Design, train, and validate ML models for computer vision, sensor fusion, signal processing, and predictive analytics.
• Develop and optimize ML pipelines for on-device inference, including quantization, power/performance tuning, and DSP/NPU acceleration.
• Monitor, test, and optimize the performance of deployed models to ensure accuracy, scalability, and maintainability.

Data Processing & Analysis

• Build data ingestion, preprocessing, and feature-engineering pipelines for both edge and hybrid (Edge + Cloud) deployments.
• Extract, process, and analyse large datasets to generate actionable insights and continuously improve model performance.

Collaboration

• Work with cross-functional teams-architects, embedded developers, PMs, UI/UX, and customers-to develop and integrate ML functionality into real products.
• Participate in prototyping, PoCs, and contribute to customer dialogues and technical presentations.
• Participate in technical discussions, document your work, and clearly explain the trade-offs and decisions behind the solutions you present.

Stay Current

• Keep up to date with the latest trends, tools, and technologies in AI/ML to ensure our solutions are cutting-edge.

We are looking for -

• Strong hands-on experience in Python, ML frameworks such as PyTorch or TensorFlow, and classical CV libraries (OpenCV, scikit-learn).
• Ability to build and deploy ML models for Edge or Embedded platforms, preferably with experience on Qualcomm, Nordic, NXP, or similar SoCs.
• Familiarity with quantization, model compression, benchmarking, and inference profiling on constrained hardware.
• Experience with data pipelines, including data validation, augmentation, and performance analysis.
• Understanding of end-to-end ML lifecycle, including experimentation, evaluation, and deployment in production environments.
• Master's or PhD in ML, Robotics, Autonomous Systems or related fields.
• 2+ years of hands-on experience developing and deploying ML models in production.
• Proven experience in one or more of:
  • Computer vision
  • Time-series or sensor-data ML
  • LLM-based or hybrid AI systems
• Effective communication skills and experience working in cross-functional teams.
• Passionate about staying up to date with emerging technologies, methodologies, and industry trends in AI/ML.
• Bonus: Knowledge of MLOps, FastAPI, Docker, CI/CD, and cloud platforms such as Azure or AWS

We Provide -

• Cutting-Edge Projects: Opportunity to work with industry-defining technologies in terms of applied research and pushing functional boundaries.
• Vibrant Work Environment: We have technical experts from 25 nationalities as part of our team and disruptive ideas are a daily occurrence whether it is a groundbreaking mesh technology, a radical approach to manage power and performance on edge devices, or creative solutions to enhance model efficiency.
• Work-Life Balance: We understand the importance of balancing work and personal life. Our flexible work hours and remote work options help you maintain this balance.
• Competitive Pay: We offer a salary that aligns with industry standards, ensuring you are fairly compensated for your skills and experience.
• Generous Vacation Time: Enjoy a healthy work-life balance with 25 days of annual paid vacation. We believe time off is crucial for your well-being and productivity.
• Health and Wellness Benefits: Dedicated yearly health and wellness allocation.
