The Role
Senior IC who owns the software running on BOAB Ventures' AI-enabled acoustic buoy systems end-to-end — embedded Linux on ARM, cross-platform DSP library, and the IoT cloud handoff. Our products deploy on U.S. submarines and integrate with the sonobuoys we manufacture. You will regularly go to sea on small boats to deploy, test, and recover the systems you build. Operator feedback from those trips directly shapes your architecture. The team is small, the org is flat, and architecture decisions you make this quarter get fielded next year. Responsibilities • Develop, troubleshoot, test, deploy, and debug buoy software in Linux using modern GNU tooling. Current stack is C++17 / Python 3.12+ in ROS2; ROS2 is being removed. • Develop and maintain a cross-platform DSP library for real-time ARM A-series and cloud computing environments. • Deploy to sea on small boats to launch, test, and recover systems. Observe operator workflows, identify gaps, and feed findings back into the architecture. • Debug at the hardware-software boundary — read schematics, scope signals, and isolate the failing layer yourself. • Maintain the API with the cloud team consuming acoustic data via MQTT (real-time) and S3 (servicing-interval offload). • Build documentation, containers, and CI/CD pipelines that enable technicians to scale buoy production. • Plan and execute system-level field testing under the reality that maritime test time is expensive, unpredictable, and scarce. • Mentor junior engineers as the team grows. Requirements • 8+ years of embedded software experience. New graduates will not be considered. • Demonstrated experience deploying code on fielded devices where real-world test time is limited and unpredictable. • Strong C/C++ programming, testing, and debugging fundamentals. • Strong version control fundamentals. • Linux development environment experience. • Ability to work with hardware engineers to debug systems where bugs live between hardware and software. • Excellent verbal and good written communication skills. • Physically able to participate in at-sea operations: lifting, carrying, maneuvering on a small boat, fine manipulations in a maritime environment. • Eligible for SECRET or TOP SECRET clearance. Preferred • Maritime operations experience — small boat ops, over-the-side handling, field repair, or sea logistics. • Prior military service or history working directly with military customers and operators. • Experience physically deploying alongside end-users: defense field ops, robotics field trials, remote sensing, oceanographic research, or similar. • Low-level protocol experience: I2C, SPI, CAN, asynchronous serial. • Embedded IoT modems and the AT command set. • CMake, ament/colcon, Docker, GCC cross-compilation, and embedded CI/CD tooling. • Python proficiency. • FreeRTOS and its modules (filesystem, network drivers).
