Japan is currently one of the few countries in the world with a legal framework supporting autonomous robotic delivery in urban environments.<\/p>\n\n\n<p>At LOMBY, we develop both hardware and software entirely in-house, leveraging Japan\u2019s strong manufacturing ecosystem to build highly reliable delivery robots designed for real-world deployment.<\/p>\n\n\n<p>As we move toward mass production and large-scale deployment in 2026, we are seeking a Senior Simulation Engineer who can accelerate the development and validation of our autonomous driving technology through high-fidelity simulation environments and scalable testing infrastructure.<\/p>\n\n\n<p>This role is ideal for engineers passionate about solving complex robotics challenges and contributing directly to the social implementation of autonomous mobility systems in dense urban environments.<\/p>\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<p><strong>\u25a0 Job Description:<\/strong><\/p>\n\n\n<p>\u30fbDevelopment of simulation environments for autonomous delivery robots<\/p>\n\n\n<p>\u30fbValidation and evaluation of autonomous driving systems in simulated environments<\/p>\n\n\n<p>\u30fbScenario generation and edge-case testing for public-road operation<\/p>\n\n\n<p>\u30fbSensor simulation and digital twin development<\/p>\n\n\n<p>\u30fbIntegration of simulation pipelines with real-world robot data<\/p>\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<p><strong>\u25a0 Specific Tasks:<\/strong><\/p>\n\n\n<p>LOMBY is currently developing its robots toward mass production in 2026. Our 5th-generation pre-production models have already been deployed in collaboration with Seven-Eleven Japan and are operating daily across nine stores in Tokyo.<\/p>\n\n\n<p>In this role, you will be responsible for building simulation systems that improve the safety, robustness, and scalability of our autonomous driving stack. You will work closely with autonomy, perception, and robotics engineers to reproduce complex real-world environments in simulation and accelerate development cycles.<\/p>\n\n\n<p>A key challenge is accurately modeling Japanese urban environments, where robots must safely coexist with pedestrians, cyclists, narrow streets, parked vehicles, and unpredictable human behavior.<\/p>\n\n\n<p>You will have the opportunity to work across the full robotics development lifecycle\u2014from simulation architecture and algorithm validation to real-world deployment and operational feedback analysis.<\/p>\n\n\n<p>This position follows a hybrid work model.
