Job description

The Role 

The software team at K2 builds software across the stack, from gateware & micro firmware to high level satellite control to Ground Software and all the associated testing, and we're looking for an SDET who shares our belief that test infrastructure is a first-class engineering discipline. You will be embedded directly within the flight software team, working shoulder-to-shoulder with the engineers writing the code that flies our spacecraft owning the automation frameworks, test tooling, and HIL infrastructure that make rapid, confident software deployment possible. 

This role is not a QA function. You will be a builder. In your first 6 months, you will design and ship core test automation frameworks and integrate them into our CI/CD pipelines. In your first year, you will own end-to-end test coverage across multiple spacecraft subsystems and lead HIL testing campaigns alongside flight software engineers, proving the software is ready to go to space. In your first two years, you will have operated your test systems against hardware that has been launched to orbit. 

Responsibilities 

  • Design, develop, and own software test frameworks targeting K2's flight software stack, including subsystems for propulsion, GNC, power, thermal, and communications
  • Build and maintain automation tooling that integrates seamlessly into CI/CD pipelines, enabling fast and reliable flight software deployment
  • Develop hardware-in-the-loop (HIL) and software-in-the-loop (SIL) test infrastructure in close collaboration with flight software engineers
  • Create tooling for test execution, data collection, and anomaly triage that gives engineers clear, actionable signal
  • Reduce flaky and nondeterministic tests; continuously improve coverage, pipeline reliability, and test execution speed
  • Collaborate with flight software, avionics, and systems engineers to define test requirements, write test plans, and execute verification campaigns
  • Analyze test results to identify and characterize failures, and drive resolution across the team
  • Maintain documentation for test infrastructure, procedures, and hardware configurations 

Qualifications 

  • Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Aerospace Engineering, or a related STEM field, or equivalent professional experience
  • Experience building and maintaining test automation frameworks, not just executing tests written by others
  • Experience with CI/CD systems (e.g., GitLab Pipelines, GitHub Actions, Jenkins) and version control (Git) 

Nice to Have 

  • Experience with hardware-in-the-loop (HIL) testbeds or embedded systems testing
  • Experience testing avionics, spacecraft, robotics, autonomous vehicles, or other safety-critical hardware
  • Rust programming experience, including embedded or no_std environments
  • Knowledge of real-time operating systems (RTOS) or bare-metal embedded firmware
  • Familiarity with aerospace communication protocols (RS-422/485, Ethernet, UART, SpaceWire, Ethernet)
  • Experience with electronics test equipment: oscilloscopes, logic analyzers, power supplies
  • Containerization experience (Docker, Kubernetes) for test environment management
  • Experience with Embedded Linux
  • Familiarity with shell scripting 

Compensation and Benefits:

  • Base salary range for this role is $123,000 - $175,000 + equity in the company
  • Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
  • Comprehensive benefits package including paid time off, medical/dental/vision/ coverage, life insurance, paid parental leave, and many other perks
