SENIOR SYSTEMS SOFTWARE ENGINEER Location: Austin, TX (Hybrid on-site, with travel) Travel: ~20% typical; up to ~50% during field exercises and partner/military deployments Clearance: U.S. Citizen with the ability to obtain a security clearance ABOUT NODA NODA is a veteran-owned, venture-backed technology company transforming how unmanned systems collaborate in complex, mission-critical environments. As NODA scales across products, partners, and deployment environments, keeping the system coherent in practice — not just on paper — is what separates a platform that works in the field from one that only works in a demo. Our Systems Software Engineers are the people who can stand at the seam between subsystems — software, networking, RF, and hardware — and make sense of what's actually happening when something breaks in degraded, contested, or denied conditions. You won't be the deepest RF, networking, or hardware specialist in the room, but you'll be able to hold your own in that conversation, pinpoint where in the stack a problem actually lives, and write the software — or pick up a multimeter — needed to prove it. THE ROLE As a Systems Software Engineer, you will work across NODA's cross-system infrastructure — the messaging fabric, gateway, and runtime built on real-time messaging frameworks (DDS, ROS/ROS2, and similar) that coordinate fleets of heterogeneous unmanned systems in real time — debugging and resolving issues that don't respect team boundaries. You'll pinpoint performance and integration issues end to end, write software stacks under a systems architect's supervision where the work falls outside Core Engineering's product ownership, and work directly with networking, RF, and hardware subject matter experts when an issue requires investigation below the software layer. You'll also support the System Health function — characterizing performance baselines, analyzing crashes to root cause, and producing the verification evidence the organization relies on for release decisions. KEY RESPONSIBILITIES - Debug and resolve cross-system issues spanning software, real-time messaging, networking, RF, and hardware — owning the investigation even when the root cause sits outside your primary depth - Pinpoint performance and latency issues in cross-system infrastructure (messaging fabric, gateway, runtime) supporting multi-agent coordination, and drive them to resolution - Write and maintain software stacks under a systems architect's supervision, for work outside Core Engineering sub-teams' product ownership - Investigate and characterize system behavior under degraded, intermittent, or contested link conditions - Perform hands-on hardware diagnostics using basic bench tools (multimeter, oscilloscope) to isolate issues at the hardware/software boundary - Hold credible technical conversations with networking, RF, and hardware SMEs — translate their findings into system-level constraints and software fixes - Contribute to System Health: performance baselining, system-level verification, crash analysis to root cause, and KPI/dashboard evidence used for release go/no-go decisions, with a focus on driving measurable improvements in latency, reliability, and uptime - Identify and mitigate cross-system risks impacting mission effectiveness, including in live exercises or deployments - Support integration tooling, CI/CD for cross-system components, and automated regression in SIL/HIL environments - Maintain Interface Control Documents and integration contracts between major platform components, and translate field/operational requirements into system constraints Core Engineering and architects can build against - Build observability into cross-system components (logging, tracing, metrics) to make the next debugging pass faster REQUIRED QUALIFICATIONS - 5+ years of professional software engineering experience, including significant time debugging distributed, real-t
