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.

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, treating measurement as a core requirement, not an afterthought.
• Meet delivery SLAs and provide first-line technical support and maintenance throughout the engagement.
• Document account-specific configurations, assumptions, and preferences for continuity and clean handover.

About You

• 5+ years of software engineering experience, with a track record of shipping and operating production systems.
• Full-stack comfort: proficient in Node.js, Python, and SQL, able to customize outputs, build integrations, and automate exports across the stack.
• Hands-on API experience: designing, exposing, and documenting APIs, mapping data to a client's schema, and working with legacy or non-REST systems.
• Strong client-facing skills: professional, responsive, and comfortable working directly in a client's channels (email, calls, Microsoft Teams) with both engineers and non-technical estimating staff.
• Metrics-driven: you define quality metrics, track accuracy trends across iterations, and make progress quantifiable and defensible.
• Self-contained and autonomous: you can own technical delivery for multiple accounts and navigate ambiguity, shifting requirements, and staggered timelines.
• B2+ English, ensuring effective communication and documentation with US clients.
• Bonus: exposure to LLM/AI applications, or familiarity with residential construction (framing, foundation, roofing, siding, interior scope) and estimating workflows.
