Who you are:

• 3+ years of experience in software development would be ideal.

• Strong backend web development skills with experience going from problem to deployment.

• Proficiency in both web development (Javascript, Node.js) and Python.

• Experience building cloud infrastructure (AWS, GCP, Azure) at scale.

• Excited by working on a small team where your contributions have an outsized impact.
