This is not a report-writing role. This is hands-on engineering for real platforms operating in unforgiving environments in support of critical national missions. You'll design, write, and deploy production software that directly controls autonomous behavior, vehicle health, and mission execution. Your work will run on real hardware, in real water, on real missions. If you care more about results than rituals, shipping than slide decks, and owning outcomes over checking boxes, you'll fit right in. This team values progress with discipline, fast iteration with bounded risk, and engineers who take responsibility end-to-end. We move quickly, learn continuously, and expect our software to work the first time it matters. Why This Role Is Different * You'll work on fielded systems, not demos. * Your software will control vehicles, not dashboards. * You'll have real ownership, not just tickets. * You'll be expected to move fast, think clearly, and deliver. * You'll help define how autonomy software gets built, not just follow a script. If you want to work where engineering decisions matter, where progress is valued, and where the mission is real, this is the role. Primary Responsibilities * Build mission-critical autonomy software using modern C++ and Python on Linux-based systems that operate in constrained, contested environments. * Translate high-level system intent into executable software, breaking down complex autonomy and vehicle requirements into clear, testable implementations. * Architect and evolve scalable autonomy frameworks, emphasizing modularity, performance, and long-term adaptability across multiple vehicle platforms. * Ship real features by developing, integrating, and testing new capabilities in existing codebases, with accurate estimates and ownership from design through deployment. * Collaborate like an engineer, not a spectator, actively contributing to technical debates, design reviews, and trade studies that resolve real constraints. * Mentor and raise the bar, supporting junior engineers and strengthening the team's overall technical rigor and execution velocity. * Own quality without paralysis, writing unit and integration tests that matter, analyzing failures, and fixing root causes instead of papering over symptoms. * Work across disciplines with systems, hardware, and test engineers to ensure software behaves correctly as part of a larger, real-world system. * Continuously improve how we build, refining tools, workflows, and processes in an Agile, iterative environment that values pragmatism over dogma. ## Related Videos - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [Robots are coming into the wild!
