WALTER: Senior Fullstack Engineer (Ruby+React)

Headquarters: Remote URL: http://gowalter.co

Description

Our client is a full-service digital product agency.

They build businesses at the intersection of content and commerce, and since 2020, we've been focused on the creator economy and online education space.

We're a distributed team based in Canada.

For this project specifically, a good part of the client team is based in Europe, so we're looking for candidates in EST or compatible timezones (anywhere from Eastern North America through Western/Central Europe) with strong overlap to a EST/CET working day.

This is a temporary contract role.

Anticipated start date is as soon as possible.

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 by the time you start, 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 is 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.

There's no Rare Days PM on this engagement (the client owns PM, so we're looking for someone who is self-directed, communicates clearly, and can operate effectively inside 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 the existing engineers on the project (your primary pair during ramp-up) 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, not just problems - 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

Requirements

What we're looking for - 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.

team - You're self-directed: you can pick up a ticket, ask the right clarifying questions, and ship it without needing constant check-ins - You're motivated by feedback and care about the craft.
