About the Role Mercor is partnering with a leading AI lab to train frontier models on high-quality insurance reasoning data. We're hiring Surety Underwriters & Bond Specialists to design realistic bonding, credit-analysis and bond-claim scenarios, evaluate model outputs against established market standards, and help shape how the next generation of AI reasons about contractor capacity, obligee requirements and default resolution.

We welcome contract and commercial surety underwriters, bond producers, surety claims professionals, and surety credit analysts from carriers, agencies, reinsurers and bond departments. Surety is a credit-driven discipline distinct from hazard underwriting, and this role reflects that.

What You'll Do Design realistic scenarios involving bid, performance and payment bonds, single and aggregate capacity, work-in-progress analysis, indemnity and collateral, commercial and court bonds, and bond-default resolution

Create work products such as capacity recommendations, credit analyses, bond approvals and declinations, obligee form reviews, indemnity requirements and claim-resolution strategies

Write "golden" reference responses at experienced surety-professional quality

Grade AI-generated responses against structured rubrics for credit judgment, capacity reasoning, contract and bond-form accuracy, and default-resolution realism

and unrealistic default or recovery strategies

Provide written feedback the research team uses to improve model behavior

Participate in onboarding office hours and calibration sessions

You're a Positive Fit If You Have 2+ years of professional experience in surety underwriting, bond production, surety claims, or contract-surety credit analysis

Have worked with at least one bond category, such as contract surety, commercial surety, court and fiduciary bonds, license and permit bonds, or subdivision bonds

Can read contractor financial statements and work-in-progress schedules and translate them into capacity and credit conclusions

Understand the three-party surety relationship and how indemnity, collateral and subrogation differ from insurance loss payment

Demonstrate excellent written reasoning, commercial and credit judgment, and high attention to detail

Can distinguish surety credit decisions from property-casualty risk underwriting and ordinary claim adjudication

Bonus Qualifications AFSB, CPCU, ARM, CPA, or comparable designation

Both underwriting and surety-claims experience

Experience with AIA and other standard bond forms, or with public-works statutory bond requirements
