Senior Systems Software Engineer

About the role

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

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-time, or multi-service systems in production
• Strong proficiency in C++ and/or Python, with the ability to write production-quality software with architect-level supervision on system design
• Experience with real-time or low-latency messaging/middleware (e.g., DDS, ROS/ROS2, ZeroMQ, MQTT, gRPC) in distributed or multi-agent contexts
• Solid working knowledge of networking fundamentals (TCP/IP, multicast, basic routing) sufficient to debug connectivity/performance issues and converse credibly with networking engineers
• Working familiarity - conversational depth plus basic debugging, not specialist design work - with RF/wireless concepts (link quality, interference, basic link budget reasoning)
• Comfortable using basic hardware bench tools (multimeter, oscilloscope) to debug at the hardware/software boundary
• Demonstrated ability to debug across layers - application, network, RF, and hardware-adjacent - and to know when to pull in a specialist versus solve it directly
• Experience with Linux systems and command-line debugging tooling
• Due to the nature of the position, U.S. citizenship is required due to ITAR regulations, along with the ability to obtain and maintain a DoD security clearance.

Preferred Qualifications

• Experience operating or debugging systems in contested/denied conditions (jamming, intermittent links, degraded bandwidth)
• Experience with Linux-based or real-time systems in resource-constrained, embedded, or edge environments (embedded Linux, bare-metal, RTOS)
• Familiarity with containerization for edge deployment (Docker/K8s) and observability tooling (OpenTelemetry, Jaeger, or similar)
• Experience with simulation, HIL/SIL pipelines, or sim-to-field validation workflows
• Familiarity with security considerations in tactical comms or cross-domain solutions
• Prior work in defense, aerospace, or other mission-critical/regulated environments
• Experience authoring ICDs, requirements traceability, or MBSE artifacts
• Exposure to tactical radios, MANET, or mesh networking in a support/integration capacity

Skills & Attributes

• Comfortable being the generalist in the room - credible across software, network, RF, and hardware conversations without needing to be the deepest expert in any one
• Strong ownership instinct; debugs to root cause rather than handing off at the first sign of unfamiliar territory
• Results-oriented - thinks in terms of measurable system KPIs (latency, reliability, uptime), not just task completion
• Clear written communicator - translates field/debugging findings into structured specs, crash reports, and feedback Core Engineering can act on
• Operates well under a systems architect's supervision on unfamiliar scope, without needing constant direction

Growth Path at Noda

• L5 - Systems Software Engineer: Owns individual debugging and integration tasks within cross-system infrastructure; writes software under architect supervision; builds working fluency in networking, RF, and hardware-level debugging.
• L6 - Senior Systems Software Engineer: Owns end-to-end resolution of cross-system performance, latency, and integration issues with minimal supervision; contributes independently to System Health baselining and crash analysis; represents Systems Engineering in cross-team design sessions.
• L7 - Staff Systems Software Engineer: Drives systems-level technical conduit work independently - translates field and customer requirements into system constraints, owns ICDs for assigned subsystems, and is a primary escalation point for integration risk, release-readiness, and mission assurance evidence.
