Full Stack Software Engineer

Crystal Knows

Crystal helps companies deeply understand the personality, behavior, and motivations of their most important peoplke -- employees, customers, prospects and job candidates.

Crystal has raised $7M in VC funding led by Salesforce Ventures, has thousands of customers globally and is currently an ambitious remote team of 20 people.

The Role

As we build and scale Crystal over the next few years, our product & engineering team is growing along with it. We're building the largest, most accurate personality platform in the world - it's a huge project that requires close collaboration between data analysis, machine learning, and social science.

  • Having a healthy approach to product velocity and technical debt
  • Taking our work very seriously, but not taking ourselves too seriously
You'll be working alongside a talented product team to translate Crystal's powerful data into everyday business value, and you'll be on the ground floor helping us build the foundation for an enduring, impactful company.
