Position Introduction/Key Duties
Cimarron is seeking a Senior Software Test Engineer to support our partnership with a commercial aerospace company at their rocket production facility in Cedar Park, TX. Your role as a Software Engineer on the test team will be critical to the success of Firefly Aerospace Software for use on launch vehicles, spacecraft, and launch facilities. You will use all-digital and hardware-in-the-loop simulation environments to test our Flight and Ground software. This will include testing of software changes where you will act as a formal independent peer reviewer for software changes. Software Engineers on the test team will also be responsible for developing and executing formal qualification software tests and certification tests including safety-critical testing as required by the U.S. Space Force Launch Facilities and the FAA, for pre and post launch software safety. You will be part of the Aerospace Software Engineering Group and will work closely with Flight Software, Ground Software, and Software Simulation personnel to provide thorough tests for our software before use on a launch vehicle, spacecraft, or launch site.
Through this partnership, Cimarron supplies skilled technical talent in support of our customer's advanced launch and space systems. This customer designs and builds small- to medium-lift launch vehicles, lunar landers, and orbital vehicles for government and commercial missions from low Earth orbit to the Moon and beyond. Together, our teams leverage advanced carbon composite structures, patented propulsion technologies, and common components across platforms to move fast, improve reliability, and deliver payloads at a lower cost.
Key Duties:
  • Design and develop test procedures for testing our Ground and Flight Software in all-digital and hardware-in-the-loop simulation environments.
  • Develop software for automating test case execution and report generation.
  • Setup automated testing of daily commits of new Ground and Flight Software and act as a peer reviewer for Merge/Pull Requests.
  • Create unit tests for simulation models, Flight Software, and Ground Software.
  • Adhere to customer test requirements, whether internal or external.
  • Develop and document requirements, designs, plans, and schedules.
  • Provide accurate test development milestones and communicate them to stakeholders.
  • Use Firefly Aerospace Software Engineering development processes and best practices.
  • Actively learn new test technologies and techniques and apply them to Firefly Aerospace Software testing.

Required/Desired Skills, Experience, and Education
Required Skills, Experience, and Education:
  • Due to facility security requirements, only U.S. citizens or permanent residents are eligible for consideration at this time.
  • 5 or more years fulltime industry experience with formal software testing and reporting.

  • Development experience under the Linux operating system.
  • Knowledge of the Agile Software Development Model.
  • Experience using Git version control on a commercial software product.
  • Bachelor's degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience, with a strong portfolio demonstrating relevant projects and accomplishments.

Desired Skills, Experience, and Education:
  • Advanced degree in Software Engineering, Computer Sciences, or Computer Engineering.
  • 7 or more years of experience with formal software testing and reporting for releases, FQT and/or Software Certification.
  • Exceptional C/C++ or Python development skills.
  • Experience with software tests running in the Red Hat Enterprise Linux 8 Real-Time operating system.
  • Practical experience using an Agile Software Development framework like Kanban, SCRUM, or Lean Development.
  • Experience using Atlassian Confluence, Jira, and Bitbucket.
  • Experience using the NASA Trick Simulation Environment.
  • Practice using the GitFlow Workflow.
