  • Partner with your front-end counter-parts and SREs to support observability, performance, and reliability initiatives

  • Contribute to architectural decisions that improve the performance, security and cost-efficiency of our platform

Qualifications

  • Strong alignment with our values
  • You are proficient in English (spoken, written, and reading) at a CEFR Level C2 / ILR Level 5
  • Deep expertise with Ruby on Rails, with an emphasis on infrastructure and architectural improvements
  • Solid experience working with MySQL and/or Postgres
  • A strong track record of improving performance, scalability, and system reliability
  • 5+ years of experience in a back-end engineering role, ideally focused on infrastructure or platform systems
  • Comfortable working autonomously in a fast-paced, fully remote environment

Requirements

  • Bonus points for having helped scale an early-stage product to 1M+ monthly active users
  • Experience with front-end technologies (especially React)
  • Experience building internal tooling or SDKs for use across engineering teams
  • Experience reducing infrastructure or tooling costs through in-house solutions

Benefits

  • Fully remote: work from anywhere in the world!
  • Autonomy and trust to do your job: we care about outcomes over everything else.
  • Paid time away: all employees are given 35 days of PTO annually. We also offer a paid sabbatical after 5 years.
  • Generous U.S. benchmarked compensation and startup equity no matter where you are in the world.
  • Awesome medical coverage with 100% coverage for you and your family, or medical reimbursement options where applicable!
  • Parental leave for parents expanding their family, or just starting one.
  • Home office stipend to help you get up and running.
  • Learning & development stipend to help you level up your professional skills.
  • Annual bonus potential for roles that don't already receive variable income or commission.
  • Company retreats: Twice a year, the Circle team gets together for a fully paid company retreat in incredible places around the world!
