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

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
