<p style="min-height:1.5em">We're hiring a senior full-stack engineer to help us build the next version of FeedbackFruits.</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">We believe in engineers who stay close to the product: domain experts who pay attention to how users actually behave and use the platform.</p></li><li><p style="min-height:1.5em">Most of the work comes down to one thing: making the product better. We rethink each feature from the user's perspective and rebuild it on stronger foundations, together with our designers and product managers.</p></li><li><p style="min-height:1.5em">We modernise the stack as we go, moving from Rails + Ember.js to Rails + Hotwire. There's deeper technical work alongside it, on performance, stability, and the platform, all in service of a product that feels faster and more reliable.</p></li><li><p style="min-height:1.5em">Stabilisation and simplification are our top concerns, from both a product and an engineering standpoint. We'd rather fix root causes for the long term than patch symptoms, even when patching would be quicker.</p></li><li><p style="min-height:1.5em">Our long-term aim is to get closer to our users by shipping faster, moving from one monthly release with regular hotfixes toward continuous delivery.</p></li><li><p style="min-height:1.5em">We've also adopted agentic coding and integrations to sharpen how we work, and we value multipliers: engineers who raise the people around them and put the team before their own output.</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>What you'll do:</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Join one of our engineering squads and own full-stack delivery on the roadmap, from backend logic and database design to the server-rendered UI it connects to</p></li><li><p style="min-height:1.5em">Lead the migration of Ember features to Rails + Hotwire, which means understanding the existing functionality, redesigning it thoughtfully together with PMs/designers, and shipping something better than what was there before</p></li><li><p style="min-height:1.5em">Handle support escalations and legacy bug-fixing as part of the mix alongside feature work. The balance will depend on which squad you join, but keeping the codebase healthy and customers unblocked is part of the job</p></li><li><p style="min-height:1.5em">Contribute to improving our CI/CD practices and deployment pipeline as we work toward more frequent, more reliable releases</p></li><li><p style="min-height:1.5em">Keep performance in mind across the stack</p></li><li><p style="min-height:1.5em">Build and maintain integrations with Learning Management Systems using LTI and partner APIs</p></li><li><p style="min-height:1.5em">Participate in code reviews and technical design discussions, bringing both quality standards and a pragmatist's sense of what's worth the effort</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>What you bring:</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">You have 5+ years of professional software engineering experience and Ruby on Rails is your home stack: you've shipped production code with it, you know its conventions, and you're comfortable in its edges</p></li><li>&l
