About The Position

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. This position is for an existing vacancy. Senior Backend Engineers to help build iRoofr is building the application foundation that will define how AI is integrated across our entire product — and we're looking for t. You'll be a core contributor on the team establishing the integration architecture and agent patterns that product teams across Roofr will build on top of. This is early, foundational work — you're setting the standard, not following it — and the code you write will have outsized reach and impact across the entire company.

Requirements

5–8 years of backend software development experience
Practical, production experience building AI-powered systems — you've shipped agents, integrations, or LLM-powered features at scale
Hands-on familiarity with LLM APIs and agent frameworks (e.g. Anthropic Claude, OpenAI, LangChain, or similar)
Experience building evaluation pipelines for LLM-powered systems — you understand why 'it seems to work' isn't good enough and have built the tooling to prove it
Strong integration engineering background — you know how to design reliable connectors to external services that hold up in production
Experience building data pipelines for AI use cases, including familiarity with RAG, embeddings, and vector search
A track record of building backend systems that scale — you care about architecture, not just shipping
Strong sense of ownership — you don't wait to be told when something needs fixing or improving
Clear communicator who can collaborate across teams and explain technical decisions without jargon
Experience at an early-stage or high-growth company, and comfort operating in a fast-moving environment
Genuine curiosity about AI and what it can unlock — and the engineering discipline to build it the right way

Nice To Haves

Experience with PHP/Laravel is an asset; what matters most is deep backend engineering fundamentals and the ability to ramp on a stack

Design and maintain rigorous evaluation frameworks for AI systems — including accuracy benchmarks, regression suites, and automated quality checks that give the team confidence to iterate quickly
