Software Engineer I (India)

Build the AI that builds teams

Mercor trains large-scale models that predict on-the-job performance more accurately than any human interview. Our platform already powers hiring at the top AI labs, and we scaled from $1 M to $100 M ARR in 11 months—making us the fastest-growing AI startup on record.

What you’ll do

In your first year you’ll ship production code every week across Python- and Go-based services and a React/Next.js frontend that screens millions of candidates. You’ll design new microservices—real-time ranking, interview analytics, and payouts that move millions of dollars—while pairing with senior engineers to profile, test, and harden our LLM-powered agents. You’ll speak directly with users, turn pain points into specs, and own features end-to-end.

You’ll thrive here if

You have solid CS fundamentals and projects you’re proud to demo; you iterate fast—prototype, test, ship in days—and care as much about product polish as system performance. Curiosity about LLMs, retrieval, and ranking is a bonus; you’ll learn alongside engineers who have shipped at Jane Street, Citadel, Databricks, and Stripe.
