Senior Fullstack Engineer (Ruby+React)

Our client is a full-service digital product agency focused on the creator economy and online education space since 2020. The team is distributed based in Canada, working on a major build for a leading platform in the creator economy involving a native Community feature.

• 7+ years of full-stack engineering experience, with substantial production work in Ruby on Rails and React
• Comfortable in a Rails monolith of meaningful size, able to navigate an unfamiliar codebase and match existing conventions
• Strong with Postgres (writing efficient queries, understanding indexing, reasoning about migrations on a live database) and familiar with Redis in caching or background-job context
• Experience working with React in a production app (component patterns, state management, integrating with a Rails backend)
• Experience with real-time features, multi-tenancy, or scale concerns; familiarity with ActionCable/AnyCable, Stream.io, Pusher, or similar is a plus
• Effective communication with technical and non-technical audiences; comfortable presenting work directly to a client team
• Self-directed: able to pick up a ticket, ask clarifying questions, and ship without constant check-ins
• Motivated by feedback and cares about craft; prefers raising concerns early
• Available to work in an EST or compatible timezone (Eastern North America through Western/Central Europe) with strong overlap to EST/CET working day
• Comfortable working as a contractor

Nice to have:

• Prior experience on creator-economy, publishing, or community products
• Background working as an embedded contractor inside 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

• Build and ship full-stack features across the Rails service layer and the React frontend on the client's community platform
• Pick up tickets from the Linear board, scope your own work, and deliver production-quality code with strong test coverage
• Participate in the client's sprint rituals, demos, and touchpoints, speaking confidently about technical decisions, trade-offs, and delivery status
• Collaborate closely with the existing engineers on the project and with the client's internal engineers and PM
• Help drive the team toward upcoming beta and release milestones, flagging risks early and proposing solutions
• Contribute to architecture and integration discussions where relevant (e.g. real-time infrastructure, feed/messaging via Stream, performance and scaling questions)
• Write code reviews that raise the bar without slowing the team down

This is a temporary contract role. Available to work in EST or compatible timezones (Eastern North America through Western/Central Europe) with strong overlap to EST/CET working day. Comfortable working as a contractor.
