About the Role

As a Software Engineer, Applied AI on Mercor's Enterprise team, you'll operate at the intersection of engineering, product, and customer success. Engineers on this team are builders first, embedding directly with enterprise clients to design and implement technical solutions that unlock the full value of Mercor's platform while applying strong systems and product thinking where it matters. The work spans everything from architecting integrations and writing production-grade code to deploying scalable solutions in production environments, always tied closely to measurable business outcomes.

  • Experience building and deploying production systems in cloud environments (AWS/GCP/Azure).

  • Comfort working directly with customers and explaining technical concepts to non-technical stakeholders.

  • High ownership mindset with the ability to navigate ambiguity and operate autonomously in high-stakes environments.

  • Impact: Your work defines how leading enterprises deploy AI-powered human intelligence systems.

  • Learning: Gain deep exposure to real-world applications of AI across industries and use cases.

  • Growth: Work across engineering and product with fast paths to ownership.
