Senior Full-Stack Engineer (Contract)

About Us

Our client is a full-service digital product agency that builds businesses at the intersection of content and commerce, focusing on the creator economy and online education space since 2020. We are a distributed team based in Canada.

Location

Remote, EST or compatible timezones (Eastern North America through Western/Central Europe) with strong overlap to a EST/CET working day.

About the Project

You'll be joining a major build for one of our clients, a leading platform in the creator economy. They're rolling out a native Community feature that gives their users' most engaged audiences a place to gather, talk, and come back between sends, unlocking a premium upsell and stronger retention for the platform. The project is mid-development, with a beta window and a release event planned for later this year. You'll be embedded into a small, focused team and shipping production code from day one.

About the Role

We're looking for a senior full-stack engineer comfortable working primarily in Ruby on Rails and React, who can drop into an existing codebase, ramp up quickly, and start delivering meaningful tickets within the first few weeks. You'll work alongside our existing engineering leads on this engagement, share planning and working sessions with the broader client team, and contribute directly to features being shipped to end users.

The stack includes Ruby on Rails with Postgres and Redis (Docker for local dev), a React frontend, with real-time and feed infrastructure powered by Stream.io. We use GitHub for code management and Linear for ticketing. This role is hands-on, with the client owning product management. We're looking for someone self-directed, who communicates clearly and can operate effectively within a client's processes and rituals.

Responsibilities

• 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 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 (e.g., real-time infrastructure, feed/messaging via Stream, performance and scaling).
• Write code reviews that raise the bar without slowing the team down.

Requirements

• 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 make changes that match existing conventions.
• Strong with Postgres (writing efficient queries, understanding indexing, reasoning about migrations) and familiar with Redis in a caching or background-job context.
• Experience working with React in a production app (component patterns, state management, integrating with a Rails backend).
• Experience with apps where real-time features, multi-tenancy, or scale are real concerns (familiarity with ActionCable/AnyCable, Stream.io, Pusher, or similar is a plus).
• Effective communication with both 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 it without constant check-ins.
• Motivated by feedback and a strong sense of craft.
• Available to work in an EST or compatible timezone (Eastern North America through Western/Central Europe) with strong overlap to a 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.

Engagement Details

• Type: Temporary contract, full-time allocation.
• Location: Remote, EST or compatible timezone (Eastern North America through Western/Central Europe).
