Backend Software Engineer

Handoff is the AI agent that runs a construction company. We help remodelers automate estimating, streamline operations, and win more work - backed by real-time cost data, intuitive design, and workflows that “speak contractor.” With over 10,000 monthly active users and $6B in annualized project volume already flowing through our platform, we’re becoming the trusted partner for the people who build our homes.

We are backed by $25M+ raised from Y Combinator, Initialized, and Greycroft. Our team is distributed across hubs in Austin, São Paulo, and Buenos Aires, and we are deeply focused on building intuitive, high-impact solutions that make a real difference for our users.

You'll be the dedicated, client-facing engineer behind Handoff's AI-automated takeoff platform for our enterprise construction accounts. Think of yourself as the technical owner of two to three enterprise relationships: you'll embed with each client's software and estimating teams, customize our deliverables to their exact standards, stand up intake and delivery workflows, and iterate until our outputs clear a measurable quality bar.

You'll partner with a Construction Account Manager who owns the business relationship while you own everything technical, from first pilot to production integration with their POS/ERP systems. This is a high-ownership role for engineers who like ambiguity, direct customer contact, and being accountable for real business outcomes.

📋 Preparation Priorities (Key Areas to Clarify):

• 1. Relying on bloated enterprise playbooks instead of nimble, early-stage growth tactics.
• 2. Inability to tie creative growth ideas back to hard financial unit economics.
• 3. Slow decision-making speed or resistance to shipping imperfect MVPs.
