Requirements

• 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, and excel at making smart tradeoffs between complexity and speed to ship the right things quickly
• Curiosity: A genuine motivation to move metrics and grow the business through thoughtful product decisions, not just technical execution

Responsibilities

• 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

Preferred Qualifications

• Direct experience on a growth team or working on acquisition/monetization initiatives
• Data-driven mindset with curiosity about user analytics and behavioural patterns

• Experience with A/B testing tools (Google Optimize, Optimizely, VWO, etc.)
