  • Build and launch new capabilities and products that bring significant value to customers

  • Work closely with different engineering teams and product teams.

An ideal candidate has:

  • 5+ years writing production backend systems code

You get brownie points for:

  • Experience with data pipelines in the relevant domain

We Offer:

  • Attractive compensation, both cash and equity-based on previous experience and expertise. We want you to share in our upside

  • An opportunity to be a part of our growth journey through a people-friendly stock option plan 

  • 7-year for post-termination option exercise (vs. standard 90 days)

  • Remote-first Culture

  • Flexible PTO
