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. At NewsBreak, we design our overall rewards package to attract top talents. Depending on the position, the role may also be eligible for discretionary bonus and options. Your recruiter can share more details during the hiring process.

Search Research Intern Jobs in CaliforniaResearch Intern Jobs in California: Frequently Asked Questions
Which companies sponsor visas for research interns in California?
Universities and research institutions are among the most active sponsors for research intern roles in California. UC San Diego, UC Berkeley, Stanford, and Caltech regularly host international researchers. On the industry side, companies like Genentech, Illumina, NVIDIA, and various biotech firms in the San Diego and San Francisco Bay Area have documented histories of sponsoring research-focused positions, particularly for candidates coming through academic pipelines.
What visa types are most common for research intern roles in California?
J-1 visa is the most common visa for research interns in California, particularly through the Research Scholar or Intern exchange visitor categories, which many universities and national labs administer directly. F-1 students with valid OPT or CPT authorization can also work in research intern roles without a separate employer-sponsored petition. H-1B visa sponsorship is less common for internships given the temporary nature of the role, though some full-time conversions may involve H-1B later.
Which cities in California have the most research intern sponsorship jobs?
The San Francisco Bay Area, including cities like Berkeley, Palo Alto, and South San Francisco, concentrates a large share of research intern opportunities across tech and biotech. San Diego is a major hub for life sciences and genomics research, with employers clustered in Torrey Pines and Sorrento Valley. Los Angeles also offers research intern roles, particularly through UCLA, USC, and aerospace and defense contractors in the region.
How to find research intern visa sponsorship jobs in California?
Migrate Mate filters job listings specifically by visa sponsorship availability, making it easier to identify California-based research intern roles where employers are open to international candidates. Rather than sifting through general job boards, you can browse Migrate Mate for research intern positions across California's key hubs in the Bay Area, San Diego, and Los Angeles, with sponsorship status surfaced directly in the listing details.
Are there any California-specific considerations for research interns seeking visa sponsorship?
California's concentration of research universities and federally funded national laboratories, such as Lawrence Berkeley and SLAC, creates a strong institutional infrastructure for J-1 and F-1 visa sponsorship. California employers must also comply with the state's strict worker protections regardless of visa type. Research interns at federally funded facilities may face additional security clearance requirements that can affect eligibility for certain roles, particularly for nationals of specific countries.
What is the prevailing wage for sponsored research intern jobs in California?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
