What are the responsibilities and job description for the Software Development Engineer in Test (SDET) position at Quindar?

What You’ll Be Doing

Breaking stuff. We need a software engineer to focus on building and automating tests. A top candidate will be able to fix bugs of currently deployed software. This role is a mix of software engineering, DevOps, and testing. The unique part of this role does not lie within writing unit or integration tests but rather mirroring customer use cases – such as testing our satellite tracking, antenna reservation, or satellite command and control services.

Your mission will be to simulate hundreds to thousands of satellites running operations while also being chaos monkey so our system can remain resilient. Don’t worry, you do not have to be an aerospace expert – satellites are just flying computers that you see every 90 minutes. Additionally, you will oversee testing operational recovery procedures.

  • Proficiency in Python and familiarity with Typescript / Javascript
  • Experience with End-to-End test suites such as Playwright or Cypress

  • Independent self-starter; able to complete projects on time with minimal guidance
  • A high standard for software maintainability, quality, resilience, and performance

Background Qualifications

  • Bachelor’s degree in Computer Science (or related field)
  • 3 years [professional] experience in software test, backend development, DevOps, or other related role. Professional experience can be replaced with a self-starter who has drive, the technical skills, and is obsessed with their product.
  • Experience supporting validation and verification for complex software systems
  • Active US Security Clearance (Secret Required, TS/SCI Preferred)
