Why join us? 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. Backend Software Engineer at Handoff 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. What You'll Do Own end-to-end technical delivery for 2-3 enterprise accounts, from pilot success criteria through production rollout and ongoing support Customize our core deliverables: estimates, takeoff drawings, and summary reports - to each client's templates, naming conventions, units, materials preferences, and branding Stand up and automate intake and delivery workflows (file transfer, custom CSV exports, API payloads) into and out of client systems Expose and document Handoff's API for clients to consume, and build SKU matching that maps our estimate line items to a supplier's catalog - maintaining mappings as catalogs evolve Assess each client's tech stack (POS/ERP systems such as Oracle), recommend a realistic integration path, and assist with connections to legacy systems, scoping what's feasible and never over-promising Lead weekly calibration reviews with the client's estimating team, incorporate correction notes, and drive accuracy against agreed error-rate targets, treat
