Remote Software Engineer, Rails Backend

The Explanation Company

Time zones: EST (UTC -5), CST (UTC -6), MST (UTC -7), PST (UTC -8)
The Explanation Company ( is hiring an experienced Rails programmer to lead our efforts in building a fast and reliable API backend that scales with our product growth.
You'll report to our CEO, a seasoned entrepreneur, engineer, and former product manager for Facebook Messenger and News Feed. We’re a remote-first, distributed team within the four time zones of the continental U.S. We also get together 2-3 times per year.
What You'll Do
You'll join a small, skilled engineering team in a role we hope will be a defining one in your career. You’ll take a lead role in the overall speed and reliability of a big backend built in Ruby on Rails. This powers a React Native client that includes video calling, chatting, search, and video browsing. There is a lot of surface area, but we’ve prepared for this so you aren’t stepping into a mess. You’ll have other senior engineers to collaborate with when you need a sounding board.
You'll work on a product that's already found product-market fit. Yet, the architecture needs serious upgrades for scalability. You'll design, build, and own key subsystems like queuing, video calling backend, and infrastructure failovers. We have deep experience with Rails, and we’ve prioritized creating a strong codebase and great development environment.
On the team, we have two experienced full stack engineers that know Ruby on Rails well. We don't need to add another full stack engineer focused on feature development, instead we need to add someone whose primary interest and experience is deeper in the stack. You'll be focused on things like reducing Ruby's memory footprint, tuning database configuration, load testing, setting up effective performance monitoring, digging into New Relic, and re-architecting our socket connections for better scalability.
What You'll Bring
  • You bring deep experience in backend development. You likely have 7+ years of experience in Ruby on Rails, and you have significant experience with another language and at least one SQL database (we’re on Postgresql). You’ve gone deep on the Rails framework and understand idiomatic Rails.
  • You bring experience architecting applications of significant scale. You’ve designed and supported a system with more than a hundred thousand simultaneous users. You’re good at stress testing and architecting for speed & reliability, you're excited to focus on all the challenges that come with scaling, and you’re happy to be in an on-call rotation.
  • You like working in a fast-paced environment. You’ll be joining a small team that likes to ship quickly, making incremental progress forward. We merge into main a half dozen times each day with our continuous integration process running in 10 minutes.
  • You’re comfortable working in a remote environment. You are strong at communicating complex thoughts in writing and value clear communication.
  • You’re comfortable working in an ambiguous environment. We set clear goals as a team, but you won’t receive specs and timelines. You’ll be the one asking questions to unpack complex problems, ensuring you understand the product & business needs, and communicating your plan to solve problems.
