With our cutting-edge technology, we are seeing customers innovate and manufacture parts with unmatched reliability, speed, and quality.

You’ll be joining a close-knit team, working with experts in 3D geometry, web technologies, cloud infrastructure, firmware, and everything in between.

We also have a variety of employee-started communities at Carbon: baking, bootcamp, yoga, gaming, book club, diversity groups, and many more that you can participate in, and maybe even start your own!

As a Software QA Engineer focusing on Systems, you will be responsible for testing a large range of software, from our rich design and manufacturing interfaces to the 3D printer itself. You will play an essential role in validating how the various systems of Carbon’s products interact with our software.

  • Become an expert on the various software systems in the Carbon 3D printers and accessories and be able to troubleshoot and debug issues
  • Assess risk, develop test strategies, and execute test plans around new features by collaborating with developers, designers, and product managers
  • Help improve engineering and testing efficiency by defining better processes and best practices
  • You have:

  • Proven skills in hands-on testing and finding ways to break products
  • Experience developing test plans, test cases, assessing risk, and filing bugs
  • Strong written and verbal communication skills
  • Effective program management skills to be able to follow through on issues and track progress across multiple teams
  • Experience debugging and deep-diving into issues
  • An incredibly methodical and detail-oriented mindset
  • Big plus(!) if you have:

  • BS or MS Degree in Computer Science, Electrical Engineering, Mechanical Engineering or equivalent
  • 2+ years experience in software testing
  • Experience testing or troubleshooting across multidisciplinary systems
  • Automation and scripting experience (we use Python!)
  • Experience with a logging analytics platform (we use Splunk!)
  • Experience with JIRA and Confluence
  • You do not need to match every listed expectation to apply for this position. Here at Carbon, we know that diverse perspectives foster the innovation we need to be successful, and we are committed to building a team that encompasses a variety of backgrounds, experiences, and skills.
