Jobs at Cubit Capital

Senior DevOps Build Engineer responsible for designing, building, and maintaining CI/CD pipelines that compile, test, package, and publish software across defense and government contract programs. The role owns build automation, release engineering, artifact management, and container registries end-to-end, while integrating security and compliance checks directly into the build process. Requires 8+ years of hands-on experience with CI/CD tools (GitLab CI, GitHub Actions, Jenkins), strong scripting skills in Python and Bash, and proficiency with containerization, artifact management, and cloud platforms (AWS or Azure). The engineer will partner with development, security, and compliance teams to deliver self-service tooling and standardize builds across unclassified and controlled unclassified environments.

Senior Firmware Engineer responsible for developing and optimizing low-level embedded software in C++ for flight-critical avionics and UAS systems. Will port frameworks to new RTOSes and hardware platforms, create board support packages and hardware abstraction layers, develop peripheral drivers (I2C, SPI, UART, ADC, wireless), and conduct unit/integration testing including MISRA C compliance. Requires 5+ years embedded systems experience, bachelor's degree in Aerospace/Electrical/Systems/Mechanical Engineering, U.S. citizenship, and ability to obtain DoD security clearance.

Lead an embedded Linux software team building mission-critical defense systems, splitting time between management and individual contribution. Design and implement C/C++ Linux daemons, REST APIs, and system services for aerial platforms and deployable manufacturing infrastructure. Manage team standups, architecture reviews, and cross-functional coordination with autonomy, avionics, and mechanical/electrical engineering. Engineer for real-time performance, security, and reliability while owning developer experience, CI/CD pipelines, and field operability.

Senior Software QA Engineer responsible for validating Firestorm's avionics platform—embedded Linux and RTOS flight computers, drivers, middleware, and safety-critical interfaces. Will design and execute risk-based test strategies (feature, exploratory, regression, acceptance) across HIL/SIL rigs, build Python-driven automation for serial/CAN/Ethernet I/O and fault injection, and instrument diagnostics to isolate timing and state issues before Flight Test. Expected to own system testing end-to-end, validate robustness under degraded conditions (jitter, packet loss, brownouts, watchdog resets), and collaborate with avionics, autonomy, radio, and payload teams to harden reliability on aircraft.

Senior Systems Software Engineer role at Saronic Technologies focused on designing, developing, and optimizing software systems for autonomous surface vessels. Responsibilities include implementing autonomous navigation and control algorithms, integrating software with hardware systems, optimizing network communications for low-bandwidth/high-latency environments, and conducting software testing and validation. The role requires 3+ years (Senior) or 8+ years (Staff) of software engineering experience, preferably in autonomous systems or robotics, with proficiency in C/C++ or Rust, embedded Linux systems, and knowledge of low-level protocols and networking principles.
