TL;DR · Software Systems Testing Engineer

As a Software Systems Test Engineer at Space Protection Programs (SPP), you will play a pivotal role in ensuring the safety and reliability of flight vehicles by collaborating with software developers and systems engineers to define comprehensive test cases, manage requirement verification matrices, and execute rigorous qualification testing. You will design and build automated qualification test suites on Hardware-in-the-Loop simulators using Python or other scripting tools, analyze telemetry data for system performance validation, and contribute to continuous integration pipelines. This position requires expertise in embedded software verification, system integration, and Agile methodologies, as well as proficiency with hardware diagnostic tools and environmental simulators like MATLAB and Simulink. Ideal candidates are comfortable working in dynamic mission environments, mentoring junior engineers, and driving technical execution toward delivery milestones.

What you'll do

  • Define, document, and review comprehensive system test cases with software developers.
  • Manage requirement verification matrices to map flight software requirements to tests.
  • Design and execute automated qualification tests on Hardware-in-the-Loop simulators.
  • Write and maintain scalable automated test scripts using Python or other tools.
  • Identify, reproduce, and log complex system-level bugs for developer resolution.
  • Analyze telemetry data to verify vehicle performance during test flights and simulations.

What we're looking for

  • Professional experience in software testing, systems integration, or software development.
  • Proficiency in writing and maintaining automation scripts using Python or C++.
  • Hands-on experience creating test plans, defining test cases, and developing testing matrices from engineering requirements.
  • Comfortable operating within Agile Scrum development environments.
  • Active Top Secret government clearance (US Citizenship required).
  • Experience with Hardware-in-the-Loop (HIL) simulators and embedded systems testing.
  • Demonstrated ability to debug complex system-level issues across hardware/software interfaces.
