Job description

1. Role Overview

Mercor is partnering with a leading AI research organization to engage experienced sales engineers for a project focused on evaluating how well AI systems perform real-world technical sales work. Rather than producing deliverables yourself, you will define what excellent work looks like: designing task-specific grading criteria and scoring completed work samples with rigorous, well-reasoned written justifications.

2. Key Responsibilities

• Design precise, task‑specific grading criteria for real‑world pre‑sales and solutions‑engineering deliverables (technical discovery plans, tailored product demonstrations, proof‑of‑concept and technical evaluation plans, security questionnaires and RFP responses, integration/API/architecture explanations, and product‑fit and technical‑risk assessments)


• Score AI‑generated and human work samples against those criteria, with detailed written justifications for every score


• Apply consistent, evidence‑based judgment so scores are reproducible and defensible


• Incorporate structured feedback from senior reviewers and iterate quickly on your work

3. Ideal Qualifications

• 4+ years of relevant experience as a Sales Engineer, Solutions Engineer, Solutions Consultant, Pre‑Sales Consultant, or Technical Sales Consultant


• Deep fluency in the pre‑sales craft: leading technical discovery, translating customer requirements into product solutions, delivering tailored demos, handling technical objections, supporting proofs of concept, and evaluating product fit and technical risk


• Hands‑on experience with technically complex B2B software — SaaS, cloud infrastructure, cybersecurity, data platforms, developer tools, or enterprise applications


• Exceptionally strong written communication, with the ability to explain exactly why a piece of technical work would or would not land with both technical and business stakeholders


• Detail‑oriented, consistent, and comfortable having your judgment reviewed and calibrated against peers


• Prior experience with AI training, evaluation, or human‑data projects is a strong plus
