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.
Responsibilities
Lead major architecture and software design decisions
Develop and maintain background jobs (Sidekiq) and employ caching to keep dashboards snappy under load
Own CI / CD pipelines and deployments (GitHub Actions, Docker, Kubernetes / ECS), ensuring that releases are automated, reliable, and fast
Collaborate closely with designers, product managers, and front‑end developers to create user‑friendly and visually appealing interfaces
Write clear and maintainable documentation
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
Requirements
Deep expertise in Ruby on Rails (typically 5+ years)
Proficiency in ReactJS (typically 3+ years), along with a strong foundation in JavaScript, TypeScript
Experience integrating front‑end components with Ruby on Rails backends
Experience building and consuming REST APIs
Familiarity with Git and hosting platforms like GitHub
Excellent organization and communication skills
An appetite for learning, problem‑solving, and contributing to a dynamic team environment
Nice‑to‑haves
Experience with AWS, Kubernetes, and Docker
Experience with Ruby outside of a Rails context (such as Sinatra)
Experience with PostgreSQL
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
Experience working with in‑house style guides
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)
Team off‑sites and other get‑togethers
Health Care Plan (Medical, Dental & Vision)
Family Leave (Maternity, Paternity)
Compensation Range :
$125K - $225K
