Senior Backend Engineer

**About Seoul Robotics** Seoul Robotics builds autonomous driving systems for factories, ports, logistics yards, and airports. We offer two approaches: a vehicle-centric system, where autonomy runs on the vehicle itself, and an infrastructure-centric system, where the site coordinates and drives vehicles. That lets us automate whole operations, not just one vehicle at a time. We work with global automakers and industry leaders, including BMW, Mercedes-Benz, Nissan, Hyundai, Mitsubishi, Volvo CE, Mando, LG, and SKT. We are expanding quickly across ports, logistics yards, and airports. We are an international team with members from more than 10 countries. English is our working language.
