About this role

From the Mercor listing

Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced Large Language Models.

1. Overview

Join a leading AI lab's cutting-edge GenAI team and help build foundational AI models from the ground up. We're seeking talented Full-Stack Software Engineers with hands-on production experience across modern application stacks — Python, Java, Rust, C#, C++, and TypeScript — to build, integrate, and stress-test real software on top of frontier models before they ship. Engineers work directly with the AI lab's engineering manager on fast-moving projects and are expected to onboard quickly and contribute working code early.

This is a full-time engagement of 40 hours per week.

2. Key Responsibilities

  • Build and ship full-stack applications, services, and internal tools — in Python, Java, Rust, C#, C++, or TypeScript — that exercise frontier model capabilities end to end.

  • Integrate pre-release model APIs into working software, including the surrounding scaffolding: tool interfaces, evaluation harnesses, and telemetry.

  • Diagnose and document model and integration failure modes surfaced while building, translating engineering observations into clear written feedback for the research team.

  • Prototype quickly against shifting requirements, delivering working increments with limited up-front specification.

  • Collaborate with the engineering manager and other engineers to maintain consistency in code quality, architecture, and technical documentation.

3. Core Qualifications

  • 3+ years of dedicated professional experience building and shipping production software at a recognized, top-tier organization.

  • Production experience in at least one of Python, Java, Rust, C#, or C++, plus working proficiency in a second language — this cohort is intentionally staffed across multiple language ecosystems.

  • Hands-on experience across the stack: backend services and APIs, a modern front-end framework (React or equivalent), relational or document databases, and cloud deployment.

  • Demonstrated ability to onboard onto an unfamiliar codebase and deliver working code quickly with minimal ramp-up.

  • Demonstrable career progression.

  • Ability to engage reliably for at least 40 hours/week during weekdays.

  • Strong written communication skills and the ability to explain complex technical decisions clearly.

Requirements

  • Must be eligible to work in one of: Remote, India
  • Fluent proficiency in English (Written & Verbal)
  • Reliable high-speed internet connection

Common questions

Is Mercor for freelancers or full-time contractors?

Mercor places you with one client for a defined engagement, like 'Python Tutor for 3 months', rather than having you grab small tasks from a shared queue. Most roles function as steady contract work, not one-off gigs.

Does Mercor's application require an on-camera interview?

Yes, every applicant records a video interview with an AI interviewer that asks questions about your resume. Clients review that recording to judge communication skills before matching, so there's no way to apply without going on camera.

What does asynchronous AI training work mean in practice?

No set hours, no check-ins, no meetings. You log in when you want, pick up an available task, complete it, and submit; nobody is waiting on you in real time. That's different from remote employment, where you're expected online during business hours. The tradeoff: you're competing with others for available tasks, so an empty queue means there's simply nothing to do until more work is released.

What does Software Engineering work look like for a Software Engineer, Full Stack — India?

Tasks here are scoped to Software Engineering, not generic labeling. As a Software Engineer, Full Stack — India, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Software Engineering) rather than following a one-size-fits-all rubric. If you don't have hands-on Software Engineering background, this is likely not the right listing to start with.

What specific skills does this listing call for?

Coding, Java, and React are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.

How many hours per week does this role require?

Based on the listing, this role is scoped at about 40 hours per week. Treat this as a real commitment expectation, not a loose estimate.

How much does this specific role pay?

This listing is posted at $25–$30/hr, an hourly rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

What happens when I click Apply on this listing?

You'll be taken to Mercor's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

Can I apply from outside India?

This specific role is open only to people based in India. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply.

How soon will I start working after applying to Mercor?

Not immediately. Mercor is a talent marketplace, not a task queue, so applying puts you in a pool of candidates. You start working only once a specific client, like a major AI lab, selects your profile, and that matching process can take weeks.
