# Senior Software Engineer -  Ruby on Rails at FeedbackFruits 

- **Company:** FeedbackFruits 
- **Location:** Amsterdam, Netherlands
- **Compensation:** €65k–€85k
- **Employment:** full-time
- **Posted:** 2026-10-30
- **Last confirmed live:** 2026-11-02
- **Apply:** https://jobs.ashbyhq.com/feedbackfruits/c0dfd833-e587-4c68-a9af-9d3011e3cd6d

## Job description

We're hiring a senior full-stack engineer to help us build the next version of FeedbackFruits.

- We believe in engineers who stay close to the product: domain experts who pay attention to how users actually behave and use the platform.
- 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.
- 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.
- 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.
- 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.
- 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.

What you'll do:

- 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
- 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
- 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
- Contribute to improving our CI/CD practices and deployment pipeline as we work toward more frequent, more reliable releases
- Keep performance in mind across the stack
- Build and maintain integrations with Learning Management Systems using LTI and partner APIs
- Participate in code reviews and technical design discussions, bringing both quality standards and a pragmatist's sense of what's worth the effort

What you bring:

- 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
- You write tests as a matter of course, not as an afterthought. RSpec and Capybara are part of your regular toolkit, and you write tests that actually catch things rather than just confirm the happy path
- You are user-oriented: when you're deciding how a feature should work, your first instinct is to think about the person using it, not the implementation that's most convenient
- You've worked in a legacy codebase before and come through it well. You know what to fix, what to leave, and how to leave things better than you found them without getting stuck in a refactoring spiral
- You understand CI/CD well enough to work within good practices and to nudge a codebase toward them when they're missing
- You communicate clearly, give honest feedback in code reviews, and take it just as well. You’re collaborative without needing everyone to agree with you
- You are pragmatic and document your decisions; you'd rather make a thoughtful trade-off and write it down than chase the perfect solution indefinitely
- Familiarity with Ember.js or migration scenarios from it to Hotwire is a genuine advantage here; experience with AI dev tooling, Azure, or observability practices would serve you well too

What you get:

- Hybrid work schedule (3 days onsite)
- 25 paid holidays per year
- A day off for your birthday
- Advantageous pension scheme
- 3 days of volunteering leave per year
- €550 Learning & Development budget per year + 3 days paid leave for learning
- Travel allowance and Swapfiets subscription
- Free access to our office gym
- Unlimited access to mental health support via OpenUp (EU, US, and AUS)
