Senior Fullstack Engineer – Ruby, React

This is a fully remote position, open to applicants in Brazil.

📋 Description

• Develop and deploy full-stack features within the Rails service layer and the React frontend of the client's community platform.

• Select tasks from the Linear board, define your own scope of work, and produce high-quality production code with comprehensive test coverage.

• Engage in the client's sprint rituals, demonstrations, and checkpoints, articulating technical choices, trade-offs, and the status of deliverables with confidence.

• Collaborate closely with the current engineers on the project (your main pair during onboarding) as well as with the client's internal engineers and project managers.

• Help guide the team towards forthcoming beta and release milestones, identifying risks early and suggesting solutions instead of merely highlighting issues.

• Participate in discussions regarding architecture and integration as needed (e.g., real-time infrastructure, feed/messaging through Stream, performance, and scaling considerations).

• Conduct code reviews that elevate standards without hindering the team's progress.

⛳️ Requirements

• Over 7 years of full-stack engineering experience, including significant production work in Ruby on Rails and React.

• Proficient in navigating a substantial Rails monolith. You can explore an unfamiliar codebase, identify patterns, and implement changes that align with existing conventions instead of conflicting with them.

• Strong knowledge of Postgres (writing efficient queries, understanding indexing, and reasoning about migrations on a live database) and familiarity with Redis in caching or background-job scenarios.

• Experience with React in a production application (component patterns, state management, and integration with a Rails backend).

• You have worked on applications where real-time features, multi-tenancy, or scalability are significant concerns, and you possess insights on the trade-offs (familiarity with ActionCable/AnyCable, Stream.io, Pusher, or similar is advantageous).

• Ability to communicate effectively with both technical and non-technical stakeholders, and comfortable presenting your work directly to a client team.

• Self-motivated: you can take a ticket, ask the appropriate clarifying questions, and complete it without requiring constant oversight.

• You value feedback and are passionate about your craft. You prefer to address concerns early rather than deliver work that you are not proud of.

• Must be available to work in an EST or compatible timezone (Eastern North America to Western/Central Europe), ensuring substantial overlap with an EST/CET working day for sprint rituals, pairing, and client interactions.

• Comfortable with contract work.

• **Nice to have**

• Previous experience with creator-economy, publishing, or community-oriented products.

• Experience working as an embedded contractor within a client's engineering team.

• Familiarity with deploying Rails applications at scale (Heroku, AWS, or similar).

• Experience integrating with third-party real-time/feed/chat services.

🏝️ Benefits

• Competitive salary and flexible work hours.

• Opportunity to work on cutting-edge technologies in a collaborative environment.

• Access to professional development and training resources.

• Supportive team culture that values innovation and creativity.
