About SAIGroup

SAIGroup is a private investment firm that has committed $1 billion to incubate and scale revolutionary AI-powered enterprise software application companies. Our portfolio, a testament to our success, comprises rapidly growing AI companies that collectively cater to over 2,000+ major global customers, approaching $800 million in annual revenue, and employing a global workforce of over 4,000 individuals.

SAIGroup invests in new ventures based on breakthrough AI-based products that have the potential to disrupt existing enterprise software markets. SAIGroup's latest investment, JazzX AI , is a pioneering technology company on a mission to shape the future of work through an AGI platform purpose-built for the enterprise. JazzX AI is not just building another AI tool—it's reimagining business processes from the ground up, enabling seamless collaboration between humans and intelligent systems. The result is a dramatic leap in productivity, efficiency, and decision velocity, empowering enterprises to become pacesetters who lead their industries and set new benchmarks for innovation and excellence.

Role Overview

As JazzX's Mortgage Underwriting SME, you will be the single-domain authority for residential mortgage underwriting across product, engineering, and operations. You will own how underwriting decisions are defined, explained, validated, and operationalized into the JazzX Mortgage Application — ensuring that automated underwriting and assistant experiences faithfully reflect real-world practice, are defensible for regulatory and secondary-market needs, and meaningfully improve outcomes across personas (loan officer, processor, underwriter, closer, post-close QC, servicing).

This is a hands-on position. You will perform representative underwriting assessments, translate rules and compensating-factor logic into machine-actionable decisioning, lead validation of AI-assisted underwriting, map persona-driven workflows and handoffs, and train product and operational teams so the application reliably reduces rework and accelerates decision throughput.

What You'll Do

Hands-On Underwriting & Decision Documentation

• Underwrite a representative set of U.S. residential mortgage loans (purchase, rate-term refinance, cash-out, manual AUS, AUS overrides) and document outcomes in a compliance-ready format (approve / suspend / decline + detailed rationale, conditions, and exception handling).
• Capture decision rationale tied to policy, compensating factors, AUS findings, and investor requirements so engineers and product teams can implement exacting rules.
