Today, much of that logic sits in handwritten C++. You will move it into behavior trees or a similar formal model, so that a reader can follow and test a flight from a file. You will also define how these models request flight skills from the autopilot, and you will make the stack reusable on a second robot. This is a technical authority role with no people to manage. You will join an autonomy team of five engineers, report to the Team Lead Autonomy, and work closely with our Principal Systems Engineer. We want a strong robotics generalist with deep C++ skills and real depth in at least one area: state estimation, motion planning, control, or perception.\nThe day-to-day\nOwn the behavior layer: design the nodes, the ports, and the structure that makesa flight readableand testableas data rather thanas code.\nMove the remaining flight authorityout of hand-written logicand intothe tree, and prove thatthe new path behaveslike the old one before we deletethe old one.\nDefine howthe companion computer asksthe autopilotfor a flight skill, and howit readsback whether that skill is running, finished, or refused.\nDraw the line between what is shared across robotsand what each robot writesfor itself, so thata second platform reusesthe stack insteadof forkingit.\nMake failures legible: a log and a trace should tella reader whichcheck said no, and why.\nWork acrossthe autonomy, perception, platform, and testing teams, sincethe behavior layer touchesall of them.\nRaise the technicalbar: design reviews, code reviews, and the written arguments thatgo with them.\nMentor engineers, without holdinga management line.\nYou should apply if you\nHave around 5 years or more of robotics software experience. Leadership experience is not required.\nHave deep C++ expertise, and the judgment to design a system that other people will extend.\nHave real experience with behavior trees, or with another explicit way of expressing robot behavior, and clear opinions about where that approach breaks.\nHave a breadth of knowledge across robotics: state estimation, motion planning, control, or perception. Depth in at least one of them.\nHave Experience withrobotsthatrunin the physicalworld, not onlyin simulation.\nPossess the ability to take a design apart in a discussion and put it back together bette\nNice to haves\nExperience withBehaviorTree.CPP ora comparablebehaviortreelibrary, includingtoolingaroundit.\nExperience withROS 2, DDS, and the design questionsthatcomewitha distributedroboticssystem.\nExperience withPX4, ArduPilot, orMAVLink, and withthe splitof workbetweenan autopilotand a companioncomputer.\nExperience withdronesorotheraircraft.\nExperience withsimulation, software-in-the-loop, hardware-in-the-loop, orreplay-basedtesting.\nExperience makinga roboticsstackworkfor morethanoneplatform.\nOpen source contributionsin robotics.\nStrong writtencommunication.
