Software Engineer, Autonomy

About the roleYou are responsible for creating the core decision-making framework, algorithms, and models that guide multi-aircraft coordinated wildfire suppression. At the nexus of the perception pipeline, suppression execution engine, and operator command interface, your systems will rapidly develop and adapt strategies in a changing wildfire environment to achieve suppression goals. You will collaborate directly with firefighters, pilots, and your engineering colleagues to determine and validate system requirements.What we doRain integrates with early wildfire detection to dispatch autonomous aircraft to suspected ignitions. Once dispatched, Rain's Wildfire Mission Autonomy System perceives the fire, shares intelligence, develops a suppression strategy, and when approved, completes the water drop and evaluates its efficacy. Combining wildfire mission management, path planning, fire perception, suppression strategy, and suppressant targeting, Rain's technology gives fire agencies the ability to stop wildfires in their earliest stages, before they grow out of control.ResponsibilitiesBuild and integrate mission-level autonomy frameworks for goal-oriented behavior, task assignment, and system-level coordinationEnable intuitive human command and supervision, communicating intent, and building operator confidence in mission-critical contextsDevelop algorithms for collaborative autonomy involving multiple aircraftEnsure real-time performance and reliability of autonomy software, especially under compute-constrained and communications-limited conditions.Design autonomy software with fault-tolerance, fail-safe behavior, and robustness to uncertain environments or degraded sensors.Validate and test in simulation and in flight, ensuring mission success in challenging conditions faced by firefighting aircraftCollaborate closely with other members of the engineering team to develop and test the algorithms that power the wildfire mission autonomy systemContribute to simulation environments for training, testing, and validationQualificationsDeep expertise (6+ years of experience) in software engineering for UAS, robotics, or other safety-critical applicationsStrong proficiency in C++14 (or newer) development for resource-limited environmentsKnowledge of planning, state machines, or behavior treesBackground in robotics, control systems, or aerospace autonomyFamiliarity with simulation tools (e.g., Unreal Engine, AirSim, AFSIM)Understanding of communication protocols, real-time constraints, and embedded systemsWhat will make you a great fitYou're excited about Rain's mission to stop wildfires before they grow out of controlYou thrive in small teams, where you can see the immediate impact of your knowledge and expertiseYou have experience with reinforcement learning or adaptive autonomyYou're familiar with STANAG/DoD autonomy standards and DO-178CYou've previously worked with uncrewed aerial systems, aviation, aerospaceYou've served as a firefighterYou are willing to travel at least 15% of the year for validation testingLocationThis is an on-site position.
