Senior Full Stack Engineer, Growth - Contract

About Roofr

At Roofr, we’re obsessed with our customers. We constantly gather feedback to shape, prioritize, and launch the products they truly need. That’s what makes Roofr’s CRM special. We started by building essential sales tools like aerial roof measurements and digital sales proposals. But when our customers asked for a simple, affordable way to manage and scale their entire businesses, we listened. So, we created a CRM that connects these solutions—along with payments, material ordering, and more—into a seamless, powerful platform. With a clear roadmap ahead, we’re excited to continue expanding and leading the market with innovative products.

We have an amazing culture, strong financials, and best-in-class company metrics. It’s an exciting time to be part of an extraordinary startup that is already successful, yet still early enough to offer its team significant growth, equity, and the opportunity to make a real impact.

What You'll Get to Do

• Drive cross-product impact: Work across multiple product domains simultaneously—building experiments in Proposals, optimizing onboarding flows, and developing features that directly impact acquisition, monetization, and retention metrics
• Move fast, responsibly: Operate in a Kanban environment where priorities shift based on experiment results and business needs, requiring you to balance rapid iteration with quality engineering practices
• Own end-to-end user journeys: Build features that span the entire customer lifecycle—from signup and onboarding to subscription upgrades and hand-offs to implementation teams
• Pioneer AI-driven experiences: Develop and iterate on novel AI-enhanced workflows and experiments that represent the cutting edge of roofing industry technology
• Lead with autonomy: Work in a self-directed environment with our product designer and Growth EM, taking ownership of product decisions and driving features from conception to delivery
• Build with experimentation in mind: Rapidly set up A/B tests and feature variations, prototype new experiences to drive user value, and help us learn and iterate on growth strategies with measurable business impact
• Develop full-stack solutions: Build performant React components and work with Laravel backend following DDD patterns to create robust, scalable features that maintain code quality while enabling rapid experimentation
• Make pragmatic trade-offs: Know when to optimize for speed vs. complexity, always considering the unique needs of cross-domain features and growth experimentation
• Shape the future of roofing software: Join a small, passionate team where your individual contributions directly influence product direction and company growth trajectory

What You'll Bring to the Role

• Strong full-stack foundation: 5+ years of experience with JavaScript, React, and backend development (preferably OOP with Laravel/PHP), with 2+ years building scalable, multi-tenant SaaS products that serve real users
• Database expertise: Strong PostgreSQL skills including query optimization, indexing strategies, and performance tuning for multi-tenant SaaS applications
• Growth engineering mindset: Experience building for experimentation and metrics-driven iteration, with a track record of breaking down complex problems into testable proofs-of-concept and rapid experiments
• Cross-functional collaboration: Proven ability to work effectively with marketing, product, and design teams, consistently communicating technical tradeoffs to meet both user needs and business requirements
• Autonomous problem-solving: You’re comfortable with ambiguity and scoping solutions independently, while knowing when to collaborate. You thrive in early-stage environments where priorities shift and individual ownership drives real impact
• User-centered: You’ll have a deep belief that great products serve users while growing the business, with experience building accessible, reliable experiences that earn customer trust
• A focus on quality: You value testing and documentation as much as code
