At DesignFiles, we’re looking for a Growth Engineer with strong full-stack Rails experience to join our product engineering team.
About Us:
At DesignFiles, 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 Engineer, you’ll sit at the intersection of engineering, product, and growth. You’ll ship features and run experiments that directly impact customer activation, retention, and monetization. Your work won’t just be about building—it’ll be about measuring, iterating, and optimizing.
Run experiments that improve activation, retention, and monetization.
Collaborate with product, design, and marketing to test and refine onboarding flows, funnels, and client engagement touchpoints.
Use data to uncover friction points in the user journey and ship small, high-impact improvements.
Take ownership of experiments end-to-end: scope, build, ship, measure, and iterate.
Refine existing features to boost adoption and stickiness.
Contribute to a culture of clean code, rapid iteration, and measurable outcomes.
Participate in team rituals like 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, Unix Shell.
Experience with A/B testing, growth-focused engineering, and/or optimizing onboarding funnels.
Strong problem-solving skills and ability to self-unblock.
Fluent English and solid communication skills.
Team-oriented and comfortable with collaboration, idea-sharing, 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 got a portfolio of high-impact experiments or user-facing improvements you’ve shipped and iterated on, we’d love to talk.
