Job Title: Member of Technical Staff, Research Engineering

Job Type: Full-time

Location: Remote

The Role

We are seeking a Research Engineer to operate at the frontier of Reinforcement Learning (RL), developing novel environments, training pipelines, and evaluation systems that advance the capabilities of modern AI models. This role sits at the intersection of research and production, translating experimental ideas into scalable, high-performance systems.

What You’ll Work On

Architect self-contained RL environments that capture complex, real-world tasks, including reward functions, verifiers, and evaluation logic.

Design and scale episode pipelines and multi-component training processes (MCPs) to support reproducible experimentation.

Build automated data generation systems, leveraging synthetic data to accelerate training cycles without compromising quality.

Develop and integrate AI-driven evaluation and quality assurance systems for automated grading, validation, and feedback loops.

Fine-tune and optimize open-source RL models using internally generated datasets and custom training strategies.

Establish benchmarking frameworks to measure model capability, robustness,...
