About the Role

We are looking for a Research Intern to join our Agent RL Training team. You will be paired with a full-time employee as your mentor, working together to explore, from zero to one, how to apply large language models to NewsBreak’s core business, including content understanding, recommendation, agentic web browsing, and autonomous multi-step task completion.

This is a hands-on research role. You are expected to independently drive experiments, propose novel ideas, and iterate quickly. We value self-starters with deep intellectual curiosity and the drive to push boundaries in LLM post-training and agent capabilities.

Location: Onsite in Mountain View, CA office

What You’ll Work On

  • Collaborate with your full-time mentor to identify high-impact research directions for applying LLMs to NewsBreak’s products
  • Independently run end-to-end SFT experiments on LLM-based agents, and assist with RL-related exploration such as reward design and training iteration
  • Curate and build high-quality training datasets: instruction-following, preference pairs, agent trajectories, and synthetic data
  • Contribute to public publications; we encourage and support top-venue submissions during your internship

What We’re Looking For

Requirements

  • Highly motivated and committed: willing to put in extra hours when needed to push projects across the finish line
  • Genuine passion for research: you read papers for fun, tinker with models on weekends, and care deeply about advancing the field
  • Independently capable of end-to-end model SFT: with basic understanding of RL-based post-training methods (RLHF, DPO, PPO, GRPO, etc.)
  • Excellent taste in model behavior: able to reason about what “good” looks like across user-facing domains and articulate why
  • Strong Python and PyTorch skills

Preferred Qualifications

  • Publication at a top-tier venue (NeurIPS, ICML, ICLR, ACL, EMNLP, or equivalent)
  • Experience with multi-node distributed training (FSDP, DeepSpeed, Megatron-LM)
  • Proficiency in writing custom GPU kernels with Triton or CUDA
  • Experience building synthetic data pipelines for agent training
  • Familiarity with open-source RL frameworks: TRL, OpenRLHF, veRL/vLLM

Hourly Pay: $35- $50

The US base salary range for this full-time position is listed below. Pay may vary based on a number of factors including job-related skills, level, experience, geographic location and relevant education or training.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
