Artificial Intelligence • SaaS • B2B

<Handoff> is an AI-powered SaaS platform that automates estimating, proposals, invoicing, and project management for residential construction professionals, including remodelers, handymen, and fix-and-flip investors. It generates instant AI estimates from descriptions, drawings, photos, and uploaded files, and includes CRM, change order management, an AI assistant, file management, and homeowner financing tools to help contractors close more deals and run their back-office operations efficiently.

📋 Description

• 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.

🎯 Requirements

• 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.
