What they need
- 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
- 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- Comfortable triaging issues across hardware, firmware, and software boundaries under schedule pressure
- 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
- We welcome candidates from robotics, autonomy, automotive, aerospace, defense, or other mission/safety-critical systems
- Integrated regression suites into CI workflows with clear automated reporting
- Space experience is not required
- Experience producing structured verification evidence and disciplined test reports
- Built test harnesses or automation tooling in Python, C++, or similar languages
- Experience with test data collection and observability practices, including dashboards and time-correlated datasets
- Familiar with workflows such as thermal vacuum, thermal cycling, vibration, shock, or EMI/EMC support
- Experience integrating automated test environments and regression suites into CI/CD workflows
- Experience supporting environmental test events and operating hardware during structured test campaigns
- Comfortable working from ICDs and debugging across hardware/software interfaces using telemetry, logs, and lab instrumentation
- 2+ years of experience in software test engineering, system integration testing, or validation for embedded or mission-critical systems
- If you’re excited about the role but don’t meet every requirement, we still encourage you to apply
- Strong documentation and cross-functional communication skills
- Hands-on experience running system-level campaigns and operating hardware during integration or environmental test events
- Experience in mission-critical or safety-critical engineering environments
- Strong understanding of determinism, configuration control, and reducing false positives in system-level environments
