The Team
The Role: Engineer II — The "Task Finder"
What You Will Do
Drive the Omnigive Form: Build and maintain complex, highly interactive UI components using vanilla JavaScript, while seamlessly connecting them to our Rails backend.
Apply the "Omakase" Mindset: Solve problems with the framework rather than around it. You will write idiomatic Ruby on Rails code using ActiveRecord, controllers, and ViewComponents.
Champion Product Sense: Analyze requirements through a "Jobs-to-be-Done" lens. Before writing new code, you will ask, "Can the user already do this?" and actively consider edge cases and error states.
Collaborate and Ship: Balance the desire to ship quickly with the need to ship quality. You will review peers' pull requests with care, communicate blockers proactively in async channels, and default to safely shipping value to users.
Steward our Knowledge: Help maintain our institutional memory by writing clear PR descriptions, logging non-obvious decisions in commit messages, and updating internal documentation when you spot something stale.
What We Are Looking For
Strong JavaScript Skills: Deep comfort with vanilla JavaScript, as it is critical for our main donation form.
Rails & PostgreSQL Proficiency: Ability to ship features in Rails without close supervision, including writing SQL beyond simple queries (joins, aggregations, and catching N+1 problems in PostgreSQL).
Quality & Testing: A strong habit of writing useful automated tests (we use Minitest) by default, including tests that would catch the specific bugs you just fixed.
Pragmatic Frontend Focus: Experience using semantic HTML, global CSS (via design tokens), and Hotwire (Turbo, Stimulus) to build out interfaces where custom JavaScript isn't strictly required.
Independent Problem Solving: A track record of taking a well-scoped feature and driving it to completion, surfacing the adjacent work needed for a polished final product.
Our Tech Stack
Backend: Ruby, Ruby on Rails
Frontend: Vanilla JavaScript, Hotwire (Turbo/Stimulus), Semantic HTML, CSS (Design Tokens)
Database: PostgreSQL, Relational Databases, SQL
Testing: Minitest, Fixtures
Mindset: "Omakase" Rails, MVC, Object-Oriented Programming
