Software Test Engineer, Flight Software Integration & Test Operations

You will design, build, and execute structured software test procedures that validate spacecraft Flight Software (FSW) across integration milestones, system-level campaigns, and environmental test events. You will translate requirements, ICDs, and operational concepts into repeatable, high-signal procedures with objective pass/fail criteria, then execute those procedures on real hardware and integrated test environments to produce flight-ready verification evidence.

This role combines software test engineering, system integration, automation, and hands-on test operations. You will work closely with the Flight Software team to ensure features are testable, measurable, and validated under nominal and off-nominal conditions prior to launch.

Space experience is not required. We welcome candidates from robotics, autonomy, automotive, aerospace, defense, or other mission/safety-critical systems.

What You’ll Do

• Develop and maintain detailed Flight Software test procedures covering nominal mission threads, off-nominal scenarios, fault responses, safing behavior, and recovery workflows.
• Translate requirements and ICDs into structured procedures with defined preconditions, configuration baselines, operator 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 relevant instrumentation.
• Develop and maintain live monitoring and post-test dashboards (e.g., 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.

This Role Is a Strong Fit If You Come From

• Experience producing structured verification evidence and disciplined test reports.
• Built test harnesses or automation tooling in Python, C++, or similar languages.
• Integrated regression suites into CI workflows with clear automated reporting.
• Strong understanding of determinism, configuration control, and reducing false positives in system-level environments.
• Hands-on experience running system-level campaigns and operating hardware during integration or environmental test events.
• Familiar with workflows such as thermal vacuum, thermal cycling, vibration, shock, or EMI/EMC support.
• Comfortable triaging issues across hardware, firmware, and software boundaries under schedule pressure.

Required Qualifications

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

If you’re excited about the role but don’t meet every requirement, we still encourage you to apply.

Desired Qualifications

• Experience in mission-critical or safety-critical engineering environments.
• Experience integrating automated test environments and regression suites into CI/CD workflows.
• Experience supporting environmental test events and operating hardware during structured test campaigns.
