A fast growing space technology company is searching for an SDET to help test, validate, and stress their mission critical software.

• Acting as a chaos tester to uncover weaknesses and improve system resilience
• Troubleshooting and fixing bugs across deployed backend systems
• Testing APIs, databases, event driven architectures, and containerized environments
• Supporting CI and automation within modern DevOps pipelines
• Working closely with frontend, backend, and product teams to ensure quality at scale

What You Will Need

• Proficiency in Python
• Experience with Playwright, Cypress, or similar end to end testing frameworks
• Strong understanding of containerized and serverless architectures
• Skilled in API testing and distributed databases
• Experience building CI or automation pipelines, ideally with GitHub Actions
• A track record of solving technical problems with minimal oversight
• Active US Security Clearance (Secret required, TS or TS SCI preferred)
• Must meet ITAR requirements (US citizen, US national, green card holder)

What You Will Get

• Hybrid work, two days per week on site with flexibility
• Comprehensive health insurance with full coverage for employees
• Unlimited PTO with a requirement to take at least 15 days
• Most US federal holidays observed
• Quarterly wellness benefits
• 4 percent 401(k) matching
• Quarterly offsites in great destinations
• A team that values ownership, curiosity, and continuous improvement

If you are excited by the idea of testing systems at scale and helping shape the future of satellite operations, I would love to speak with you.
