Description

We’re looking for a Senior Full-Stack Ruby on Rails Engineer to lead development of our analytics dashboard. You’ll design, build, and maintain Rails APIs, background jobs, and database schemas that power data-rich React components and interfaces. You’ll work closely with product managers, designers, front-end developers, and infrastructure to rapidly push new features from ideation to production.

This is a hands-on role with plenty of scope to influence architecture, user experience, and coding standards. While we’re targeting senior engineers, we’re open to strong mid-level candidates who demonstrate leadership, ownership, and a passion for full-stack craftsmanship.

Team, Culture, and Product

We're a small engineering team looking to grow. We're a remote-only organization with most of the engineering team working from US timezones. We aim to help mobile app developers make data-driven decisions about their marketing in a secure, privacy-centric, user-friendly way. We encourage flexibility in working locations and hours but also make sure we all overlap at least briefly for a bit each day.

  • Ensure test coverage for new and existing features using RSpec and Jest
  • Employ feature flags to support trunk-based development workflows
  • Adhere to and enforce code style guidelines and best practices
  • Profile, debug, and optimize both front-end and back-end performance issues in production and staging environments

Nice-to-haves

  • Experience with advanced topics in React such as the Context Api, Memoization and Virtualization
  • Experience with mobile app development or mobile marketing
  • Experience building data-intensive user workflows - customizable tables, charts, etc

Benefits

  • Annual budget for learning and personal development (conferences, books, classes, etc)
  • Budget for fitness and well-being activities (gym memberships, fitness equipment)
  • Unlimited vacation days and a vacation stipend to make sure you take time off (we recommend at least 20 days off per year)
