Job summary

Shield AI is seeking a Mission Systems Software Engineer to develop real-time, safety-critical software for autonomous aircraft. You will define system architectures, integrate sensors and vehicle services, and drive verification across lab, flight-test, and deployed environments.

The role requires extensive experience in embedded distributed systems, RTOS, and C/C++/Rust, with potential security clearance. Collaboration across hardware, cybersecurity, safety, and test teams will be essential.

Qualifications

• 5+ years of professional software-engineering experience, including 1+ years in software architecture, systems architecture, or technical leadership.
• 8+ years for Staff; 3+ years in software architecture, systems architecture, or technical leadership.
• 10+ years for Senior Staff; 5+ years in software architecture, systems architecture, or technical leadership.
• Experience developing embedded, distributed, real-time, safety-critical, or mission-critical software systems.
• Proficiency in C, C++, Rust, or another strongly typed systems-programming language.
• Strong understanding of real-time software principles, including scheduling, concurrency, synchronization, latency, jitter, memory management, and deterministic execution.
• Experience with embedded operating systems or RTOSs, middleware, interprocess communication, networking, and data-distribution technologies.
• Experience defining software architectures, APIs, interface-control documents, data flows, deployment models, and system resource budgets.
• Experience integrating software with hardware, sensors, communications systems, navigation systems, effectors, or other mission-system components.
• Experience supporting software through requirements development, design reviews, implementation, integration, verification, system test, and deployment.
• Working knowledge of systems-engineering processes, requirements management, traceability, configuration management, and verification and validation.
• Ability to analyze system performance using instrumentation, telemetry, traces, profiling, network captures, timing data, and resource-utilization measurements.
• Strong cross-functional technical leadership, problem-solving, written communication, and presentation skills.
• Ability to obtain and maintain a U.S. Department of Defense security clearance; U.S. citizenship may be required for clearance eligibility.

Responsibilities

• Serve as a software mission systems engineer for a safety- and mission-critical real-time mission-computing system aligned with A-GRA and AMS-GRA principles, profiles, interfaces, and data standards.
• Define and maintain the end-to-end software architecture, including mission applications, platform services, middleware, operating-system interfaces, hardware-abstraction layers, networking, data distribution, component boundaries, and APIs.
• Architect for deterministic real-time performance by addressing scheduling, latency, jitter, synchronization, throughput, resource utilization, distributed processing, and CPU/GPU/accelerator allocation.
• Develop architecture views, interface definitions, data-flow and deployment models, sequence and timing diagrams, resource budgets, trade studies, and technical decision records.
• Integrate sensors, effectors, communications, navigation, autonomy, mission management, command-and-control, data-processing, and vehicle services in collaboration with hardware, FPGA, cybersecurity, safety, systems, integration, and test teams.
• Design for mission resilience and assurance through fault detection and isolation, redundancy, graceful degradation, recovery, health monitoring, cybersecurity, airworthiness, certification, and requirements traceability.
• Establish engineering practices for concurrency, synchronization, memory and resource management, deterministic execution, interface control, configuration management, and predictable component integration.
• Define and execute verification strategies across HIL/SIL laboratories, simulations, test benches, flight-test environments, and deployed systems using automated, performance, stress, fault-injection, interface, and timing tests.
• Maintain technical ownership throughout the system lifecycle by evaluating enabling technologies and supplier designs, analyzing performance, managing technical debt and modernization roadmaps, promoting reuse, and communicating architectural decisions.
