Job summary

Xona Space in Burlingame, CA, is seeking a software test engineer to design, build, and execute flight software verification across integration milestones and environmental tests. You will translate requirements into repeatable test procedures, automate telemetry validation, and produce flight-ready evidence.

You'll run campaigns on development benches and HIL/SIL setups, implement FDIR fault scenarios, and maintain dashboards for system health.

Qualifications

• 2+ years of experience in software test engineering for embedded or mission-critical systems.
• Ownership of structured test procedures including authoring, review, version control, and operational discipline.
• Experience building or maintaining test software used to execute procedures and validate outcomes.
• Comfortable debugging across hardware/software interfaces using telemetry, logs, and lab instrumentation.
• Experience with test data collection and observability, including dashboards and time-correlated datasets.
• Strong documentation and cross-functional communication skills.

Responsibilities

• Develop and maintain detailed Flight Software test procedures covering nominal threads, off-nominal scenarios, fault responses, safing, and recovery workflows.
• Translate requirements and ICDs into structured procedures with preconditions, configuration baselines, actions, expected results, and measurable pass/fail criteria.
• Build and maintain test software and utilities (command sequencing, telemetry validation, log capture, automated reporting) to execute procedures reliably.
• Run integration and regression campaigns on development benches, integrated avionics stacks, and HIL/SIL environments.
• Implement fault-focused scenarios to validate FDIR behavior, limit monitoring, safe-mode entry, and recovery logic.
• Own test data collection and time correlation, including telemetry, logs, performance metrics, and instrumentation.
• Develop and maintain live monitoring and post-test dashboards (Grafana) to track system health, event timelines, and test progress.
• Support environmental test campaigns as a primary test operator when required, executing runbooks and maintaining disciplined event logs.
