Full-Stack Rails Engineer (Growth-Focused)

We’re looking for a Full-Stack Rails Engineer who loves turning ideas into measurable results. You’ll build and iterate on features and experiments that directly improve how designers discover, use, and grow with DesignFiles.

About Us:

We’re building the go-to platform for interior designers to manage every part of their business—from concept to completion. More than 5,500 customers already rely on our tools, and our remote team of 30+ is growing. If you care about building great products that solve real problems, we’d love to meet you.

What You'll Do:

As a Growth-Focused Full-Stack Engineer, you’ll work at the intersection of engineering, product, and growth. You’ll ship features and run experiments that directly impact activation, retention, and monetization. Your work won’t just be about building — it’ll be about measuring, learning, and improving.

• Run experiments that improve activation, retention, and monetization.
• Collaborate with product, design, and marketing to refine onboarding flows, funnels, and engagement touchpoints.
• Use data to uncover friction in the user journey and ship small, high-impact improvements.
• Take ownership of experiments end-to-end: scope, build, ship, measure, iterate.
• Refine existing features to boost adoption and usability.
• Contribute to a culture of clean code, rapid iteration, and measurable outcomes.
• Participate in daily standups, sprint planning, and retrospectives.

What We're Looking For:

• 5+ years of hands-on Ruby on Rails experience with strong full-stack skills.
• Proficiency with JavaScript, Stimulus.js, CSS, RSpec, SQL, Docker, and Unix Shell.
• Experience with A/B testing, growth-driven development, or funnel optimization.
• Strong problem-solving skills and the ability to self-unblock.
• Fluent English and solid communication skills.
• Collaborative mindset and comfort with feedback and code reviews.

This is a full-time, 40-hour/week remote contract role. We’re specifically seeking candidates (not agencies) based within ±2 hours of Central European Time (CET).

If you’ve built experiments or user-facing improvements that made a measurable impact, we’d love to talk.
