Senior IoT Engineer

Job description:
About US
SensorVision is an IoT solutions development company based in Calicut. We work with clients across the US, UK, Europe, and Australia, helping them build and scale connected digital products. While IoT is a significant part of what we do, we are a product engineering company with capabilities that span the entire technology stack—embedded systems, firmware, cloud infrastructure, web applications, and mobile apps.
We are also an extended R&D team for companies that don't have IoT expertise in-house. That means every project is different—different hardware, different protocols, different use cases. We are a small team with a flat structure; you will interact directly with clients, understand their requirements and own the technical delivery.
We are looking for a Senior IoT Engineer to join us full-time in Calicut: someone who can quickly understand a new problem, pick up a new MCU or sensor, and deliver working code without hand-holding.
