Senior Embedded Linux Engineer

About Bots Unlimited Bots Unlimited is a San Antonio based product development and hardware company that designs, produces, and supports high performance technology for drones, robotics, automation, and edge AI systems. We create advanced camera modules, long range wireless solutions, embedded compute platforms, and propulsion electronics, working closely with trusted manufacturing partners to deliver reliable hardware with a globally resilient supply chain. We also provide customers with supply chain support and manufacturing services to help bring complete products to market. We operate in a fast moving, execution focused environment where team members own their work end to end and are trusted to manage themselves with a high level of accountability. Our team values initiative, clear communication, and a strong sense of responsibility, qualities that let us move quickly and ship production-ready hardware. If you are interested in building better products, we might be the right fit for you. Position Overview You’ll contribute to full-stack embedded development—from writing low-level Linux drivers to bringing up hardware prototypes in the lab. The work involves integrating high-performance camera sensors, wireless communication modules, and real-time subsystems on modern embedded Linux platforms. You'll be part of a small, fast-moving team shipping systems that operate in real environments, not just test benches. This is a full-time, exempt position reporting to the VP of Engineering. This position is remote with travel up to 25% to our company headquarters or other locations.
