Senior Back-End Software Engineer, Infra at Circle (circle.so)

This role is for a seasoned Ruby on Rails expert with at least five years of experience who specifically enjoys infrastructure challenges over building front-facing features. You should have a background in scaling systems to millions of users and a desire to build internal tools that help other developers work faster. **What makes it worth a look...** The standout feature is the US-benchmarked salary and equity offered globally, paired with 35 days of PTO and twice-yearly international retreats. It is a rare chance to focus on the technical "plumbing" of a successful remote platform while having high autonomy over architectural decisions and cost-saving initiatives. **You might be a good fit if you...** * Have deep experience modernizing Rails stacks and optimizing MySQL or Postgres. * Enjoy building in-house SDKs and libraries to replace expensive third-party vendors. * Prefer working asynchronously in a high-documentation environment without tracked hours. * Have previously scaled a product to over one million monthly active users.
