Overview

This role puts you on a frontier AI lab's GenAI team, building and testing real software on top of large language models before they're released. You'll work across the full stack—Python, Java, Rust, C#, C++, or TypeScript—to integrate model APIs, build evaluation harnesses, and diagnose failure modes. The pace is fast, requirements shift, and you're expected to contribute working code within your first week. It's a fully remote, 40-hour-per-week engagement paying $25–$30/hr.

What You'll Do5

  • 1Build and ship full-stack applications, services, and internal tools that exercise frontier model capabilities end to end in Python, Java, Rust, C#, C++, or TypeScript.
  • 2Wire pre-release model APIs into working software, including the surrounding scaffolding like tool interfaces, evaluation harnesses, and telemetry.
  • 3Spot and document model and integration failure modes you encounter, turning engineering observations into clear written feedback for the research team.
  • 4Prototype quickly against shifting requirements, delivering working increments even when the spec is thin.
  • 5Collaborate with the engineering manager and other engineers to keep code quality, architecture, and technical documentation consistent.

Requirements7

  • 13+ years of professional experience shipping production software at a top-tier organization.
  • 2Deep production experience in at least one of Python, Java, Rust, C#, or C++, plus working proficiency in a second language.
  • 3Full-stack expertise: backend services and APIs, a modern front-end framework like React or equivalent, relational or document databases, and cloud deployment.
  • 4A proven ability to onboard onto an unfamiliar codebase and deliver working code quickly with minimal ramp-up.
  • 5Demonstrable career progression and a track record of taking on increasing responsibility.
  • 6Reliable availability for at least 40 hours per week during weekdays.
  • 7Strong written communication skills and the ability to explain complex technical decisions clearly.

Who Should Apply

You're an experienced full-stack engineer who loves working at the edge of what's possible with AI. You're comfortable with ambiguity, pick up new codebases fast, and take pride in turning rough ideas into working software. You want to collaborate closely with a small, senior team and have your technical feedback shape how frontier models evolve.

Salary Insight

The engagement pays $25–$30 per hour, remotely from India, for a full-time 40-hour work week.

Application Tip

When you apply, include a specific example of a time you integrated an unfamiliar API or SDK into a production app—and what you learned from the failure modes you encountered. This role values hands-on debugging and clear post-mortems, so showing that process will help you stand out.
