About the role

Software Test Engineer focused on designing, building, and executing structured test procedures to validate spacecraft Flight Software across integration milestones, system campaigns, and environmental tests. Role combines software test engineering, system integration, automation, and hands-on test operations in an on-site Burlingame, CA environment.

Responsibilities

  • 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.

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.
