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.

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

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